Down to Earth
Thankfully, this week was a bit quieter than last. However, speculation, discussion, and official press conferences and releases continue in the wake of the loss of both an Orbital Sciences’ Antares rocket and SpaceShipTwo.
Orbital Sciences has stated that the first stage AJ26 engine – in particular, a turbopump failure – is suspected in the accident that ended their ISS resupply flight only 15 seconds after launch. Fortunately for NASA, Orbital has a plan to maintain their logistics contract to ISS. The company plans to accelerate an already scheduled upgrade to the Antares rocket propulsion system. The implication seems to be that the AJ26 engines will be retired (which are refurbished Soviet NK-33 engines built decades ago). The second piece of the plan is that Orbital will contract out ISS cargo flights to other launchers (exactly who is not identified) until the new Antares upgrade is ready. Therefore, no further flights of Antares with the AJ26 will be attempted. The company announced both the initial findings of the accident investigation and their forward plans in a press release on November 5th.
On the other side of the country in the Mojave Desert, there are still a lot of questions concerning what caused the loss of SpaceShipTwo and one of her pilots, as well as what the impact might be on the project. In the fourth daily onsite press conference from the NTSB (full briefing below), it was revealed that cockpit video shows Michael Alsbury (who did not survive) prematurely unlocked the SpaceShipTwo wing feather system. However, the feather was not actually deployed. Further investigation is needed to determine the complete error chain.
Unfortunately for Virgin Galactic, but unsurprisingly, a number of ticket holders are known to have already asked the company for a refund on their deposit for a future ride on SpaceShipTwo. The company is likely to experience significant delays before their first commercial flights, but at least their replacement vehicle is already under construction.
Before we move on to the cool stuff actually happening in space, there are two more earthbound topics I wanted to cover.
First, the midterm elections in the United States. The senate is now controlled by the Republican party and Casey Dreier of the Planetary Society has a brief but comprehensive assessment of what this will likely mean for spaceflight (including planetary science, manned spaceflight, and commercial enterprises). The summary is that no sweeping change, good or bad, is likely to be a direct result of this political swing. But it is hard to know.
Lastly, the much anticipated science fiction film Interstellar was released to what appears to be mostly great reviews. Users on IMDB are rating the film a staggering 9.1 out of 10 (keep in mind that most hyped films have very large IMDB rating inflation at release). I saw the film last night in IMAX and enjoyed it quite a bit. My recommendation is that anyone who is a fan of space, science fiction, and movies, should see this film and see it in the big format; but don’t expect to see a film that feels completely without plot holes or twinges of fantasy. This movie is “hard” science fiction in the flavor of 2001: A Space Odyssey. Recall that ASO involves advanced aliens and interstellar worm hole travel. So if you go into Interstellar expecting to not have to suspend your disbelief somewhat, you will be disappointed. I recommend you see it before reading any reviews, but if you must, here is a good one from Tim Reyes of Universe today (who liked it) and an iffy one from Phil Plait (who didn’t like it).
CollectSpace has a nice piece on how the actors in Interstellar consulted with Space Shuttle astronaut Marsha Ivins.
Coming up on Sunday, November 9, the crew of Expedition 41 (which ended with a change of command ceremony today) will return to Earth after their Soyuz undocks from the ISS. Maxim Suraev, Reid Wiseman, and Alex Gerst will depart ISS in the evening, around 7:30 PM Eastern, and land in Kazakhstan only about 3.5 hours later. Reid and Alex have been excellent ambassadors of the ISS on social media with their great posts on Twitter and Vine. You should follow them during their last day (and look at all their old posts)! Expedition 42 should be an exciting one with additional spacewalks planned.
Around the Solar System
A proposed Canadian mission (yes, Canadian!) would endeavor to search directly for life on Mars. The mission would consist of a small lander and just as small a rover. It is unclear what their budget would be, but since they are using an IndieGoGo campaign to raise a modest (in spaceflight terms) $1 million, I would suspect it is what could be called “shoestring”! Nevertheless, The “Northern Light” lander is exciting in its simple goal of scrapping away at the Martian dirt and looking for the color green. The presumption being that photosynthetic organisms may be alive just below the surface. With a launch window in 2018, the idea is ambitions, but exciting. I donated!
NASA held a press conference on November 7 to give an update on the science gained from observations of comet Siding Spring’s encounter with Mars back in October. One of the most interesting observations, to me, were the many kinds of metal detected by observing the chemical composition of Mars’ atmosphere during the encounter; the atmosphere changed as it was pelted with the dust and rock from the comet. Since Siding Spring is from the distant Oort cloud, these measurements are a window into the chemistry of our solar system as far back as the formation of the sun. The observations were done by the fleet of spacecraft humanity now has at Mars (6 in all counting rovers). Unfortunately, no pictures have come out from the surface of Mars (maybe from Curiosity, which can operate at night?) of the meteor storm that was likely visible from surface.
While comet Siding Spring’s encounter with Mars was an anticipated event, the events at comet 67P/Churyumov-Gerasimenko next week will be a highlight of the year, or even the decade, in space… if the Rosetta spacecrafts Philae lander is able to touchdown on the comet. You could read about the mission on their website here, or just watch these two brilliantly produced videos that should get anyone excited about the mission!
Talk about having a good PR department! Philae will be released from Rosetta on Wednesday, November 12, with a touchdown signal confirming landing reaching Earth at about 11 AM Eastern. NASA TV will cover the event.
Happily, There is some cool astronomy news to cover this week as well!
The ALMA (Atacama Large Millimeter/submillimeter Array) Observatory has taken a stunning image of the planet-forming disc around star HL Tau, which is 450 light years away. I should note that the data was not taken in visible light, but in wavelengths closer to radio. The gaps in the dust around the star are understood to be the orbits of planet-sized bodies forming around the star as we watch. Wow.
Observations from the W.M. Keck Observatory in Hawai’i showed an object known as G2 approach the supermassive black hole at the center of the Milky Way. G2 was thought to be a large glass cloud that would get torn apart by the black hole. But when G2 survived, scientists were forced to revise their hypothesis. The new working theory is that G2 was a binary star system that merged into one massive star due to the gravitational affects of the black hole. I wonder if the system had planets?
This was not a good week for spaceflight, with two major mishaps. The first mishap, the loss of Orbital Science’s Antares rocket, with ISS cargo onboard, mere seconds after liftoff, was like a gut punch for American spaceflight. But the loss of a Scaled Composites test pilot when SpaceShipTwo was destroyed during Friday’s test flight in Mojave was a true disaster. Not only will it be a major setback from Virgin Galactic and the NewSpace industry (and a potential PR nightmare), it was a tragic loss of life. I hope that Scaled and Virgin make the families of the deceased their first priority. You can contribute to a GoFundMe program for deceased pilot Michael Alsbury here.
So, I guess it is ok that I haven’t posted for a while; now the bad can be mixed in with a bunch of cool stuff I need to catch you up on. Here are a few of the bigger stories in spaceflight over the past couple months that you should know about.
Down to Earth
One of the biggest stories of the summer was the CCtCAP (basically, NASA contract for private commercial manned flights to the ISS) award to SpaceX and Boeing. Sierra Nevada’s Dreamchaser was cut from the competition. However, Sierra Nevada has filed an official protest. The appeal process is expected to take several months, but Boeing and SpaceX will continue working on their vehicles in the meantime. The award was worth a total of $6.8 billion (over several years) with $2.6 billion to SpaceX and the rest to Boeing. Regardless of the results of the protest, space enthusiasts should be getting excited about the first crewed flights now only a few years away!
A bill is being discussed in the US House of Representatives known as the ASTEROIDS Act, which would seek to establish legislative rules regarding the mining of asteroids.
On October 17, the Air Force successfully landed the third of their secret space plane fleet, the X-37B, in California. The spacecraft spent 675 days in orbit (wow!). A fourth flight is planned for next year.
A lot has been going on with the ISS program since my last update just after the end of Expedition 40. Soyuz TMA-14M successfully arrived at ISS in late September with three new crew members onboard. Not long after the crew returned to 6-person strength, three separate spacewalks were conducted (two from the US segment and the RS segment) on October 7, 15 and 22. Rookie astronauts Reid Wiseman and Alex Gerst got their first spacewalks and will be returning to Earth as veterans next week. Reid got two spacewalks while Alex Gerst and Barry Wilmore both got one each.
October was the month of spacewalks, but it also saw some successful ISS vehicle traffic (despite the loss of Orbital-3). SpaceX’s fourth Dragon resupply flight was recovered after splashdown in the Pacific ocean on October 24th. Their next mission is planned to launch on December 9th. Also, just the morning after the loss of Orbital-3, a Progress resupply mission launched and docked to ISS without a hitch.
You know Expedition 42 will be a fun time on ISS as well because of this awesome poster they made (most geeks should get the reference).
Around the Solar System
Back on October 8 many people in the Western Hemisphere enjoyed a total lunar eclipse in the early morning hours (at least for us in the USA). But here’s the view you didn’t expect: a video from Mercury (by NASA’s MESSENGER spacecraft) of the moon winking out as it passes into Earth’s shadow.
You know what, why don’t we just do a whole bunch of cool things spotted from around the solar system?
Next is Phobos transiting the sun as seen from the NASA’s Curiosity rover on Mars.
And lastly, we have the NASA spacecraft New Horizons, less than a year from arrival at Pluto. New Horizons is now close enough to its target that it was able to spot Pluto’s tiny moon Hydra with its modest onboard imaging systems (originally detected by the Hubble Telescope in 2005).
There is a lot of other exciting solar system news to catch up on. At Mars, two new spacecraft have recently arrived in orbit: India’s MOM (Mars Orbiter Mission) and NASA’s Maven. MOM is India’s first interplanetary mission and has already sent back some very nice images of the red planet. MAVEN is a probe designed to get a better understanding of Mars’ atmosphere (which should be a window into the planet’s history). MAVEN arrived at Mars in time to get some observations of comet Siding Springs as it had a close approach. Here are some other cool photos of the approach.
Just yesterday, China’s Chang’E 5 T1 mission, a technology demonstrator for a future lunar sample return, landed successfully in Mongolia.
Lastly, the Rosetta spacecraft in orbit around comet 67P/Churyumov-Gerasimenko has reached the final orbit form which the Philae lander will be deployed later this month. The landing site, site J, was chosen a few weeks ago in October.
Astronomers using the HARPS instrument in Chile have discovered a swarm of comets (almost 500!) around a nearby star. More evidence that our solar system is typical, rather than unique.
Wow! What a year so far! There has been a lot of radio silence here on this blog since I was busy with my flight lead assignments at work (lead ADCO for SpaceX-3 cargo flight to ISS and then Expedition 40). Also, I am still very busy planning my wedding next month. I’m not going to try to catch you up on all the amazing and interesting things that have been going on in spaceflight year, for which I apologize. To partially fill the gap, here is a list of spaceflight industry news items that happened in August, helpfully compiled by Doug Messier of Parabolic Arc. Now on to more recent news.
Down to Earth
The crew of Soyuz TMA-12M returned to Earth on Wednesday, bringing to a close the long and eventful Expedition 40 onboard the ISS. I wonder if Swanny was happy to be home? Below is a video summary of their farewell, undocking, and landing.
Flight Engineer Reid Wiseman got this shot of the Soyuz re-entering.
Unfortunately, SpaceShipTwo will likely not have its first flight to space with Richard Branson aboard until at least early next year, according to Branson during an appearance on The Late Show. In just a few weeks it will be the 10 year anniversary of SpaceShipOne’s final flight which won the Ansari X Prize. Ten years later, the burgeoning “NewSpace” industry has not sent a single person to space. Let’s hope they are finally close.
On Thursday this week the first Orion crew module, which will fly an unmanned test flight in December, was moved from the Neil Armstrong Operations and Checkout Building to the Payload Hazardous Servicing Facility where it will be fueled. Perhaps “the gap” is slowly coming to a close?
With Expedition 40 complete on the ISS, Expedition 41 will start off with just a three-man crew of Alex Gerst, Reid Wiseman, and Maxim Suraev. They will be joined later this month by the crew of Soyuz TMA-14M, which includes the first female cosmonaut, Elena Serova, since Yelena Kondakova flew on STS-84 in 1997. So far, Alex and Reid are kicking off Expedition 41 by continuing to constantly post amazing pictures on Twitter as @astro_reid and @astro_alex. Why aren’t you following them?!
Last weekend on September 7, SpaceX successfully launched a Falcon 9 rocket carrying the commercial communications satellite Asiasat-6. The next Falcon 9 rocket on deck will hopefully launch on September 19 carrying a Dragon spacecraft full of cargo to the ISS.
Around the Solar System
The Rosetta spacecraft is in orbit around the comet 67P/Churyumov–Gerasimenko, arriving earlier this summer, 10 years after launch. This “selfie” is an amazing picture that shows both part of the spacecraft and the comet in the background. Rosetta will deploy the Philae probe to land on the comet later this year. ESA is expected to announce the landing site on the comet next week.
Not wanting to be left out, Opportunity also sent home a cool summer vacation photo from the rim of Endeavour crater on Mars. Yes, this is the same Opportunity rover that landed on January 25, 2004. That would be BEFORE the last flight to space by the NewSpace industry over 10 years ago, but who is counting?
China is getting in on the party too. It seems the Yutu rover is still alive on the moon and has sent back a recent panorama.
In Part I of my 2013 year in review I discussed NASA policy and budget changes in 2013. The year for NASA can be summarized as continued excellence, with reason to be concerned for the future. Concern stems from the lack of funding or long-term policy. NASA always dominates space news, but much is also said of the emerging “private” or “New” space sector – as has been the case for the past decade – ever since SpaceShipOne won the Ansari X Prize in 2004. In part II of my review I will discuss the developments in New Space in 2013 and whether I think New Space is finally about to deliver the revolution that we have been promised.
Part II – The Idea Frontier
The 2000s brought New Space to our attention, but the 2010s will be the decade that the dream is realized, fizzles out, or is replaced by New New Space. While Virgin Galactic is making powered flights (two short flights in 2013, none to space) a horde of other bold new companies are showing up, whose ideas make the idea of a blossoming suborbital space tourism sector seem mundane.
The crazy ideas (and I say that in the most respectful way possible) started in 2012 with the announcement of Planetary Resources: The Asteroid Mining Company. Planetary Resources got attention for putting money where its mouth is; with big name and big money backers like Larry Page, James Cameron, Eric Shcmidt, and Ross Perot. Planetary Resources was followed by Deep Space Industries, another independent asteroid mining company announced in January 2013. By that same time in 2013, Planetary Resources was already working on hardware, with a ground test article of their Arkyd spacecraft. One would think that with all the backing that Planetary Resources has, the development and launch of some small space telescopes wouldn’t be too much of a stretch – SpaceX is doing it with only one billionaire – but apparently they don’t have enough billionaires. In May 2013 Planetary Resources unveiled a Kickstarter campaign to raise $1 million towards the first step in their mission: the launch of space telescopes (which they call their Arkyd model) to discover the asteroids they will later mine. Planetary Resources may have single-handedly proved the concept of crowdfunding a space mission by raising to date $1.5 million towards their goal.
But then again, after about 8 months Planetary Resources has received less than half a cent in donations from each American. Contrasted with the taxed $48 or so per American that NASA received last year, it’s not much. Numbers like that shows why the billionaires are necessary, and they are all getting in on the game. In January 2013, billionaire Dennis Tito (who paid for a trip to ISS in 2001) announced his new space project, Inspiration Mars. The extremely ambitious mission hopes to launch a manned mission to flyby Mars in 2018. The trip would be for only two people – preferably a middle-aged married couple, according to the company – but would aim to inspire the world. Hence the slogan “Send Two People, Take Everyone.” I personally think Inspiration Mars is a great idea. It does not seem to have any false or unreasonable pretenses – like intending to start a brand new multi-billion dollar industry of mining asteroids from scratch. Instead the goal is in the name: inspiration.
If achieved, the Inspiration Mars mission likely would change humanity’s perspective and focus – imagine the real life image of someone staring out through a spacecraft window at the globe of Mars? But Tito’s ambition is clearly bigger than his checkbook. A mission to Mars, even a flyby, is expected to cost billions of dollars, and no launch vehicle exists that would be able to send a manned vehicle on its way to Mars (the SpaceX Falcon 9 Heavy is expected to eventually be able to do the trick). So who pays for it? That’s what everyone was asking back in early 2013. Tito answered that question by appearing before a congressional subcommittee in November and proposing that Inspiration Mars be a joint venture with NASA. Who will pay for it? The American taxpayer? It was worth a shot, but NASA and Congress did not seem impressed or swayed by the proposal. Whether funded philanthropically or federally, Inspiration Mars would be an amazing feat. But for now the US Government won’t be helping out.
So Inspiration Mars started off as an interesting and exciting kind of New Space that quickly morphed into a grasp at money to make it an Old Space style venture, which Congress shot down. To qualify as “New Space,” generally a venture needs to avoid NASA and come up with new, novel, cheaper ways to grow the space sector on their own. Well, that’s where Mars One came in, announcing in 2012 plans to send the first manned mission to Mars as part of a reality show. Probably seeing the success of Planetary Resources’ Kickstarter campaign, the Mars One project started an IndieGoGo campaign in December 2013 to fund their orbiter and lander precursor mission in 2018. As of January 18th they have raised just short of half of their goal of $400,000.
So where does this put us? We have a lot of people with a lot of new crazy ideas. When Deep Space Industries was announced early last year, its chairman Rick Tumlison was quoted as saying “One company is an anomaly. Two companies is an industry.” But that is yet to be seen. A lot of excitement and press briefings and a few crowdfunding campaigns is enough to get made fun of by Jon Stewart (as in this April 2012 episode), but in my book, results are what matter. As far as the frontier of crazy new ideas goes, 2013 was mostly a year of announcements with results yet to come.
But that doesn’t mean that we are not seeing the glimmer of the results first foreshadowed by SpaceShipOne winning the Ansari X Prize ten years ago. Virgin Galactic’s SpaceShipTwo succeeded on 3 different powered flights in the last year: April 29th and September 5th of last year, and then recently on January 10th. They have yet to reach space, but they are clearly very close to being “operational”. Also in the suborbital sector, XCOR’s Lynx is still under development and is expected to make a flight test soon. However, on the other side of the coin, some of the promising young companies that were kicked off by the X Prize Cup and the Northrop Grumman Lunar Lander Challenge last decade have fizzled out. Armadillo Aerospace has officially been put on hold by John Carmack and Masten Space Systems never grew out of the tiny mom-and-pop operation they started as. They are doing interesting work, but are more like an R&D outfit than a company in a new industry. I don’t believe they had any flights in 2013 either.
The real results are clearly coming from the companies that are challenging the definition of “New Space” by not being afraid to work with the government to get their feet off of the ground. SpaceX is the most obvious success, with 3 flights of their Falcon 9 rocket last year, one earlier this month, and no major failures. They have demonstrated technical excellence with their low failure rate, by following through on their contract to resupply the International Space Station, and by their impressive efforts to develop a reusable rocket with their “Grasshopper” rocket. SpaceX is joined by other companies that are using NASA contracts as a funding source such as Sierra Nevada who are developing the Dreamchaser reusable space plan and Bigelow Aerospace, which may deliver an inflatable hab module to the ISS in the future.
SpaceX has even purchased nearly 100 acres near the Mexican border in Brownsville, Texas with the intent to launch commercial and military payloads – leaving operations for NASA cargo and crew missions in Florida. SpaceX is quickly morphing into something much more Old Space, with NASA, Department of Defense contracts (if their Falcon 9 rocket is certified by the DoD), and comm sat companies as their main source of revenue. Perhaps 2013 was the year that New Space gave its last gasp before it faded away as a false dichotomy. After all, you can’t fund a high tech company off of Kickstarter and dreams. But you can fund it off of NASA and the DoD. Perhaps the distinction between New and Old space isn’t whether you are funded by the government or not, but rather what your motivations are, and whether you keep the dream alive. So far SpaceX is still run by an eccentric billionaire with dreams of Mars. Meantime, no one at United Launch Alliance, Boeing, ATK, or Lockheed is publicly saying the goal of their company is to send the human species to the stars. And if SpaceX can keep that dream alive, maybe there is something to New Space after all. We will have to wait and see.
It’s been a busy of December since my last post. A hectic week at work, following the thermal pump malfunction on December 11th, kept me very busy right up until my vacation to visit family around Christmas for a week. I am back in Houston now and working on catching up on what’s been happening outside of my little world for the past few weeks. This post will be followed shortly by a 2013 year in review post, so stay tuned!
Down to Earth
On December 10th, NASA JSC’s Morpheus vertical take-off and landing test vehicle conducted its first free flight since the previous model was destroyed in August 2012. Very cool to watch.
Edit: and they flew another flight just a few days later on December 17th, which I missed when I first wrote this post.
On December 11th, Virgin Galactic’s SpaceShipTwo conducted a glide test in Mojave. More test are always good, but the frequency of glide tests without powered flights over the past few months was pretty much the nail in the coffin for Richard Branson’s prediction that he and his family would fly into space on the first suborbital flight on Christmas of this year. Clearly that didn’t happen. It seems likely however that Virgin will conduct another powered flight soon, possibly in the first week of January.
Doug Messier at Parabolic Arc is calling the first few days of 2014 “Launch Week”. Details on the various launches can be found over at his blog, but the quick summary is: SpaceX Falcon 9 commercial launch on Jan 3, Indian comm sat launch on Jan 5, Orbital Sciences ISS resupply flight on Jan 7, and a possible SpaceShipTwo flight.
Did you enjoy the movie Gravity? I liked it so much I saw it twice. Too bad the DVD wasn’t available for Christmas. Anyway, if you liked the movie, then take the time to watch this short behind-the-scenes clip that gives a glimpse at how some of the complex special effects were done.
The Las Vegas based company Bigelow Aerospace has put out a call for applicants to their “astronaut in-space simulations”. Basically the company wants to do their own independent look at how astronauts interact in closed quarters and also use the opportunity to improve their “crew systems” (in other words, the interior details of their inflatable space stations). Why not apply? Can’t hurt.
Be sure to go outside on January 3rd to look for the Quadrantid Meteors. They are supposed to be one of the best showers of the year, and this year the peak occurs on a new moon.
Astronaut Kevin Ford reminisced about spending Christmas in space during expedition 34 one year ago.
Folks are talking about Beyonce’s new song XO which opens with a sampling from the NASA broadcast of STS-51-L launch on January 28, 1986. The audio used is of the Public Affairs Officer reacting shortly after the shuttle Challenger was lost. The choice seems pretty tasteless and disrespectful, even if one can construe an ambiguous connection between the lyrics and the idea of a lost loved one. I personally can’t figure out if it is just a simple love song that has nothing to do with Challenger, or if it is intended to be something deeper. Listen for yourself.
The big news in orbit over the past couple of weeks was the malfunction onboard the International Space Station that led to two contingency EVAs that were prepared and executed right before Christmas. The issue also caused NASA to have to delay the launch and rendezvous of the second Orbital Sciences cargo flight to ISS, planned for a December 18th launch. The launch is now to occur in early January.
The summary of what happened is that on December 11th flight controllers started seeing anomalies in the ISS thermal cooling system. The problem was narrowed down to a faulty Flow Control Valve in one of the two pumps that flows ammonia to cool components on the outside of the station. Over the ensuing days, a few different teams were convened – one team was planning contingency EVAs to replace the pump, another was doing troubleshooting and thinking of ways to try to make the system work with the faulty valve, and another team was preparing a procedure to be executed in case the second pump failed (I was part of this team). After these teams worked night and day for over a week, it was determined that the pump should be replaced, and the first EVA was conducted on December 21st. The spacewalk was very successful; the pump removal went much better than a similar operation that replaced the same pump after a failure in 2010 during Expedition 24.
The second spacewalk was conducted on December 24th and left the station with a brand new pump and no more concerns about the thermal system for the time being. A potential third EVA was cancelled and the space station crew (and ground teams!) got a much needed break for Christmas.
The quick repair even allowed the Russian space agency to conduct their spacewalk that had already been scheduled for December 27th. One of the key objectives of the Russian EVA was to install some commercial cameras on the outside of the station. The purpose of the cameras is to make a live feed of Earth images, in fairly good resolution, available to the public. The cosmonauts got the cameras installed but they would not boot up, so they unfortately had to be brought back inside for troubleshooting.
Christmas 2013 is the 45th anniversary of an iconic photo taken by the crew of Apollo 8 while in orbit around the moon: Earthrise.
A team from NASA Goddard (with Andrew Chaikin for narration) put together a very cool (in an extremely nerdy way) recreation of how the image was captured that day (via Bad Astronomy).
Around the Solar System
On December 14th, the Chinese Chang’e 3 spacecraft came to a soft landing in the Bay of Rainbows on the Moon and quickly deployed the Yutu rover. Chang’e 3 is the first soft landing on the moon since the Soviet Luna 24 in 1976. Since that was over 37 years ago, almost 60% of the world’s population was not alive the last time there was an active rover on the moon. Emily Lakdawalla of the Planetary Society has been doing an excellent job, as usual, gathering information and compiling the best photos and video clips of the Chang’e 3 mission. Here is an update from December 14th and from December 23rd, but I recommend just following her blog directly for the best stuff!
Very cool news from the Hubble Space Telescope; recent data in ultraviolet wavelengths reveals strong evidence of liquid water geysers coming from Europa, a frozen moon of Jupiter. Previously, water geysers have been imaged in visible light coming from Saturn’s moon, Enceladus. The images are stunning. Water geysers imply an ample supply of subsurface water (either in a vast ocean or just pockets or lakes in the ice) as well as the possibility for a medium for life, and a way for our spacecraft to sample that water without needing to drill deep into the ice. More science needs to be done to confirm the Europa geysers but the current data seems very compelling. Unfortunately, it is unlikely that the Juno spacecraft, currently on its way to Jupiter, will be able to confirm the geysers. This is because Juno’s missions objectives are related to the planet Jupiter itself, not its moons, and the visible light camera on Juno is more of an outreach tool than a primary instrument.
Lastly in planetary science news, the European orbiter Mars Express should have completed its very close flyby of the Mars moon Phobos by now. As Phil Plait writes, we don’t expect to get any close up pictures from the 27 mile flyby, but the data should help scientists nail down the exact mass of Phobos.
Down to Earth
Sierra Nevada had an unpiloted glide and landing test of their DreamChaser space plane back on October 26th. Unfortunately, the left landing gear did not deploy on approach and the spacecraft crashed. The company quickly clarified that no major damage was sustained and they are looking into the mechanical cause of the stuck landing gear. The company has not released footage of the actual crash though. The video below cuts off just before landing.
Retired ISS commander Chris Hadfield’s new book “An Astronaut’s Guide to Life On Earth” is now on sale. I got my signed copy today here at NASA JSC! Commander Hadfield is back in Houston for a NASA checkup and is doing some book tour stops while here. Hope to read it and write a review soon!
November is a busy month for deliveries to the ISS. Last weekend, on November 2nd, ATV4 re-entered the atmosphere – undocking had been several days prior. A special experiment took place on ISS to get high resolution photos of the craft burning up and here are the results.
With ATV gone, we are gearing up for the arrival of the new ISS crew. The second half of Expedition 38 – Koichi Wakata, Richard Mastracchio, and Mikhail Tyurin – will launch from Kazakhstan on their Soyuz spacecraft on Thursday, November 7. As is the new flavor of Soyuz flights, they will arrive at ISS just 6 hours later. This crew is one of the most veteran-filled to share a Soyuz in a while. Wakata and Mastracchio will each be on their 4th spaceflights while Tyurin will be on his third. I expect that when Wakata returns to Earth, he will be the only Japanese astronaut on the top 50 list of most time in space (Which you can find about halfway down the page here).
The really exciting thing about this Soyuz flight is that it launches before the first half of Expedition 37 leaves ISS – which is usual how we trade out crews. Instead there will be a short period of 9 people onboard ISS for the first time since the end of the Shuttle program. Why are we doing this? So that an Olympic torch can be carried on a Russian EVA this weekend and then quickly returned two days later with the Soyuz TMA-09M crew. In order for this even to work, last Friday that crew climbed aboard their Soyuz in full re-entry suits and “relocated” their spacecraft from one ISS port to another. A lot of work for a little PR. We will see if it pays off.
Around the Solar System
On Tuesday, November 5th, India launched their Mangalyaan spacecraft to Mars. Mangalyaan is a Mars climate orbiter that will reach the red planet next year after a 10-month Hohmann transfer orbit. India’s mission is the first of two missions to launch int he current Mars window. NASA’s MAVEN mission is to launch on November 18.
I always like getting to talk hard science. There have been some great results regarding astronomy in the past few weeks:
First, astronomers from various universities collaborated on an observation that found the most distant galaxy ever imaged. The work was done at the Keck Observatory in Hawaii (shout out to my dad who does coding work at Keck on the instrument that was used!). The galaxy has an extreme redshift that puts it only 700 million years after the birth of the universe. Hopefully imaging the youngest galaxies will help us understand fundamentals of galaxy formation.
In exoplanet news, there are some developments. Planet Kepler-78b, which is a small very hot planet orbiting its star in just 8.5 hours – had its density measured (using the Doppler Shift method) and it was discovered that it is about the same size and density as the Earth. Most people are calling this the first actual “Earth-like” planet discovered in another solar system. However, it is still too close to its star to be habitable.
But even more exciting, perhaps, than this actual discovery of an “Earth-like” world is the statistical analysis (again using Keck data!) that shows that one-in-five stars in our galaxy is likely to have an Earth-sized planet in the habitable zone. Wow! You might be tempted to say “its just a statistical analysis” but really that’s all any estimate like this is ever going to be because we cannot get direct data on whether all 400 stars have planets. The more planets we discover, the better our sample size, of course. But right now it is looking promising that the follow-on missions to Kepler (JWST and others) have a high likelihood of directly imaging one of these sister Earths. We live in exciting times.
Down to Earth
Two astronauts announced their departure from the NASA astronaut corps at the end of September – Ron Garan and Greg Chamitoff. Greg Chamitoff actually worked in my office as an ISS guidance officer, almost 20 years ago (although the ISS had not been launched yet at the time).
The J-2X upper stage engine, in development under NASA contract for about 6 years for use first in the Ares program and then on SLS, will apparently be “mothballed” next year. In other words, NASA has decided J-2X won’t work for SLS so it is going on hold until they find a future use for it. Bummer.
The European Space Agency is doing rover field tests in the Atacama Desert in Chile in preparation for their 2018 launch of the ExoMars rover.
Roscosmos – the Russian federal space agency – has once again replaced their head administrator in an effort to end the string of launch failures that has plagued the program over the past few years. Good luck with the new guy.
Speaking of Roscosmos; Russian media reports that they intend to try a new Phobos sample return mission (following their failed Phobos-Grunt mission in 2011). The new mission would not occur until 2020 or later. It bears repeating: good luck.
The SpaceX grasshopper test vehicle had one more test flight earlier this month – video below – which will apparently be the last. I have to admit that I am disappointed. I hope SpaceX has something more exciting up their sleeve; the Falcon 9-R might fit the bill.
The new company out of Tucson, Arizona known as “World View” intends to send paying customers to 30 km altitude in a balloon lifted capsule. The flights wouldn’t technically take tourists to space, but would give them a high altitude view of the Earth for far longer than flights in suborbital vehicles like SpaceShipTwo. Tickets are planned to only be $75,000.
Luca Parmitano wrote a nice blog post about what it was like to capture the Orbital Cygnus spacecraft last month.
A relatively large Near Earth Asteroid, 2013 TV135, was discovered on October 8th. TV135 has a diameter of about 400 feet and came within 4.2 million miles of Earth last month. The asteroid has another close approach in 2032 for which the probability of an Earth impact is 1-in-63,000.
Speaking of asteroids, on October 15 a Russian dive team found a half-ton chunk of the Chelyabinsk impact at the bottom of a lake near Chelyabinsk, Russia. Awesome.
Around the Solar System
On October 9, the NASA Jupiter probe Juno had a close flyby of the Earth to get a gravity assist and start heading to the outer solar system. Here is a view of Earth from Juno near closest approach. And here is a diagram of the spacecraft’s trajectory showing the affect of the Earth flyby.
It’s been a whole month since I last posted, so there is some catching up to do. I’m going to try to just hit the highlights.
Down to Earth
A few quick news items from the “NewSpace” sector:
Most exciting and most recently, today Virgin Galactic flew the second powered flight of the SpaceShipTwo space plane. This test involved “feathering” the spaceship’s wings after the engine is shut down to help with a controlled “re-entry”. With this only being the second test flight of the year – the first was back in April – it seems unlikely Virgin will start flights to space by the end of the year. Still, it is awesome to see progress. Here’s a video of the flight.
ATK has partnered with Orbital Sciences to build the rocket for Stratolaunch. Orbital is designing the rocket and ATK will provide the first and second stages. For those that need a refresher, Stratolaunch is the Paul Allen project to have a 747-sized plane be the launch platform for a massive rocket that can deliver as much as 13,500 pounds to Earth orbit.
Last month Sierra Nevada’s “Dream Chaser” space plane went through some taxi tests out in California. Basically, it was just towed down the runway to test the landing gear. But if you think that’s exciting, there’s a video! Interestingly, the nose landing gear is a skid, not a wheel.
SpaceX had another test flight of their “Grasshopper” vertical take off and landing rocket. This time it was a “divert” test where it flew sideways and came back. Here’s the video.
In the NASA world there are a few updates also:
First of all, deputy NASA administrator Lori Garver has announced she will be leaving NASA for a job in the private sector (specifically as president of the American Airline Pilots Association).
Astronaut Mike Foale is also leaving NASA after a 26 year career.
A recent paper was published identifying 12 EROs (easily-retrievable objects) to add to a list of possible destinations for NASA’s asteroid retrieval mission. Unfortunately, Lori Garver (see above) was a chief proponent of this new controversial mission. Check out this article in the Washington Post outlining some of the technical and political issues that may hinder this mission.
Tomorrow night at 11:27 PM Eastern time, NASA’s LADEE (Lunar Atmosphere and Dust Environment Explorer) will launch from the Wallops Island facility in Virginia. The launch should be visible to much of the East coast, so stay up to watch if you can! The spacecraft will not have any cameras. Instead, it has spectrometers and dust scoops for studying the tenuous lunar atmosphere. Once LADEE has launched it will clear the Wallops Island launch range for the Orbital Sciences launch of their first Cygnus flight to ISS on September 17th.
A link I should have posted weeks ago is a first hand account from ESA astronaut Luca Parmitano of the EVA which was aborted in July when his helmet started filling up with water. This was probably the scariest thing to happen in spaceflight since the loss of Columbia a decade ago. Great job by flight controllers and especially Luca in staying calm under pressure.
NASA is officially no longer attempting to fully recover the Kepler Space Telescope. Fortunately, lots of people are thinking of ways Kepler can still do exciting science without the stability of three gyroscopes. One of the most publicized white papers from this past week was the idea to look for planets in the very close habitable zones of white dwarf stars.
Similarly, the WISE spacecraft (wide-field infrared survey explorer) is getting a new mission. WISE is being reactivated on a 3-year mission to look for NEOs (Near-Earth Object). As Phil Plait points out, this mission may be directly related to NASA’s asteroid retrieval mission, and the effort to find a candidate rock to go grab.
To round out the space telescope news, the Spitzer Space Telescope celebrated its 10th year in space this summer. Spitzer ran out of liquid helium coolant in 2009 but is still going strong with its “warm mission”.
In what is a startling development, the United States Air Force’s “Space Fence” will be shut down after the end of this fiscal year. The Space Fence is a key part of our orbital surveillance program. Without the space fence program there will be a gap in capability until if and when the new system comes on line in a few years. It’s very possible that without this system the risk of debris striking any given spacecraft without warning – including the ISS – goes up.

Mars rover Curiosity got an awesome set of images of the moon Phobos passing in front of Deimos. Not just a rover!

Speaking of Virgin Galactic, the term “space tourism” has been officially added to the OED.
The great XKCD comic recently did a great job describing the basics of orbital mechanics.
Somebody recreated the famous shot of a bike flying in front of the moon from the movie E.T.
In a post in July I wrote about how Hubble had determined the color of a far-flung exoplanet. What I failed to mention that they had also discovered that on this planet it probably “rains glass sideways”, which is a bit of a let down if you are wanting to visit this nifty blue world someday. The web comic Sci-Ence is apparently annoyed at how often the planets we discover are unlivable, and has created a handy guide.
Down to Earth
Parabolic Arc has a quick summary of the history of NewSpace suborbital launches, based on some tabulated data from the FAA. It is interesting to see the number of (or lack of) launches for some companies. You can really see how SpaceX is the only reall success story so far.
On the almost success story front, there is Virgin Galactic who did another SpaceShipTwo flight on July 25. Disappointingly, it was only a glide test for pilot training. Everyone is hoping SpaceShipTwp will make its first trip to space before the end of the year.
And then at the bottom is Armadillo Aerospace, which is one step away from being simply a failure story of NewSpace. Armadillo blew up a rocket early this year and hasn’t flown since. Recently John Carmack (owner and investor) announced at a conference that the company is “going into hibernation” because it is out of money and he doesn’t want to sink any more cash in it.
NewSpace aside, there is a bit more drama going on – like the mess that is the Russian space program and its politics. The prime minister publicly called out Roscosmos head Popovkin for the recent Proton rocket failure (the spectacular crash you can see in an earlier post here). Popovkin was hired just a couple of years ago to take over the space program after several other high profile failures. Surprisingly, the Proton rocket is expected to fly 4 to 5 more times this year, with the return to flight coming as soon as next month.
In what is perhaps a revealing indication of where the Russian space program’s priorities really come from, the plan to fly an Olympic torch to the ISS for a spacewalk in time for the winter games in Sochi, Russia, is coming together. The crew of Soyuz flight TMA-11M even have a mission patch design that includes an Olympic flame element.
On Saturday, August 3rd, the fourth Japanese cargo resupply craft, HTV-4, launched from Japan on the way to ISS. The mission will arrive for rendezvous on early Friday morning.
I am assigned to the day shift (7-4) in Mission Control every day this week, so I am lucky enough to have the first shift after rendezvous, where the team will maneuver HTV on the end of the Space Station’s robotic arm to “berth” or attach to the ISS to deliver its cargo.
Look at ISS tracker websites like www.heavens-above.com over the rest of the week for upcoming ISS passes overhead – as you might also catch sight of a much fainter HTV in chase. There is a bright pass over North America tomorrow morning at around 4-5 AM. ISS will be visible in Houston at exactly 5 AM.
In what might be a pretty good PR move, NASA is advertising an upcoming research opportunity… to use twins to study the affect of long duration spaceflight. How? Well when Scott Kelly flies to ISS for a year in 2015, he will come home with 10 times more days in space than his twin brother, Mark Kelly. I’m no biologist or geneticist, but I imagine that being twins, there are some variables this can isolate to better understand what will be happening to Scott during his long flight. Its a very cool offer for the Kellys to make, considering Mark is retired.
I put this news item under the “In Orbit” as a show of hope: NASA’s Space Launch System, or SLS (worst name for a rocket I’ve ever seen) , completed Preliminary Design Review at the end of July. Here’s hoping this project can stay near budget and get American back to space soon.
Around the Solar System
Happy Birthday to the Mars rover Curiosity, who has spent one year on the Martian surface as of today! Check out Phil Plait’s post for a cool timelapse of the last 365 days on Mars. It’s a great video, but a bit disappointing because of how little Curiosity has actually roved so far. Here’s to more roving in the next year! Really we shouldn’t celebrate for another 322 days, since the Martian year is about 687 days long… and let’s face it, Curiosity is a Martian.

Sally Ride is to be posthumously awarded the Presidential Medal of Freedom.
Recently returned ISS Commander Chris Hadfield announced his retirement from the Canadian astronaut corps today.
Last month, the governor of Texas signed a new law that is necessary for SpaceX to build a new spaceport near South Padre Island and Brownsville. The bill allows the mandated closure of Boca Chica Beach – a public state park – on the days of rocket launches. This bill is a big step towards SpaceX making South Texas their second launch site.
Apparently Justin Bieber made a down payment on a spaceflight with Virgin Galactic last week.
If you are a night owl (or the opposite) you should go outside at about 4:30 AM (Eastern) on Tuesday, June 11, and see if you can spot some Gamma Delphinid meteors. The possible meteor outburst may only last 30 minutes or so, but may be dramatic.
The asteroid mining company Planetary Resources launched a “crowdfunding” campaign last month to help them raise money for their asteroid hunting space telescope(s). They are getting close to their $1 million goal. I think it is worth donating (I contributed already) just for the possibility of getting the cool “space selfie” perk they are offering. They are planning to have a small video screen on the outside of the spacecraft that can display photographs that can then be themselves photographed against the backdrop of the Earth.
Warner Brothers intends to make a feature film based on the nonfiction book “Spacesuit: Fashioning Apollo”. I’ll go see it!
On Wednesday, May 29, the second half of Expedition 36 docked to the ISS in the second “express” docking. Launch to docking time was about 6 hours. The new crew consists of Karen Nyberg (American), Luca Parmitano (Italian), and Fyodor Yurchikhin (Russian). Soyuz Commander Yurchikhin is on his third spaceflight. He was just in space exactly 3 years ago for Expedition 24.
Last week, the fourth European transfer vehicle (ATV4) launched from French Guiana on its way to ISS. ATV4 is named “Albert Einstein” and will stay docked to ISS for several months.
Early tomorrow morning, China intends to launch their fifth manned spaceflight. The mission will be Shenzhou 10, and will send three taikonauts to the Chinese Tiangong-1 space station. (via NASA Watch)
The Keck Telescope in Hawaii (where my dad works) was used for some new research into the Big Bang. The giant telescope looked at stars to get spectroscopic data of their Lithium isotope content in order to confirm a prediction made by The Big Bang Theory of the universe’s origin.
