Down to Earth
SpaceX has purchased more land on the coast near Brownsville and South Padre Island in Texas, making their intentions fairly clear.
The United States Congressional Budget Office issued a report with options for reducing the national deficit. One option outlined includes completely eliminating all NASA spending on manned spaceflight. Oh dear.
The big news in the past two weeks, in my opinion, was the launch of Chang’e 3, a Chinese lunar lander. Chang’e 1 and 2 were successful moon orbiters, and the third mission, launched December 2nd, is scheduled to land a large rover on the lunar surface – the first to do so in 37 years – on December 14th. So far, China is putting their money where their mouth is when it comes to their spaceflight program.
Today, December 3rd, SpaceX launched a Falcon 9 version 1.1 with a commercial telecommunications satellite onboard. The SES-8 satellite was successfully sent on the planned geostationary transfer orbit – proving that SpaceX had sussed out and fixed the problem that marred an earlier test launch back in September. The failure of the upper stage to relight back on September 29 was traced back to frozen igniter fluid lines. As SpaceX points out in their press release, this mission is a big step towards fulfilling their long launch manifest, which includes many commercial launches, some requiring a geostationary orbit insertion. One more successful Falcon 9 v1.1 launch is needed for DOD certification. Also, the first ISS resupply flight aboard a Falcon 9 v1.1 is planned for early next year.
On November 19th, the robotic arm on the Kibo module of the ISS (the Japanese lab) was used to deploy several small “cubesats” into orbit. This is the second time the ISS has been used as a launching platform (last time was in December 2012 also using Kibo).
On November 20th, the International Space Station program celebrated the 15th anniversary of the first module launch – the Russian “Functional Cargo Block”, or more poetically “Zarya” (Sunrise)*. Here’s a short but amazing ISS timelapse to celebrate (via Universe Today).
*Nobody in Mission Operations at NASA JSC calls it Zarya.
Around the Solar System
The big story this past month (apart from recent Chinese success) has been comet ISON – the comet-of-the-century that wasn’t. ISON was a fun story to follow because the steep-diving comet (which grazed by the Sun at less than one solar diameter on Thanksgiving Day) was so dynamic that astronomers were having a hard time predicting how and when the comet might brighten, dim, or die. I had spent a week prior to perihelion (the name for closest approach to the sun) hoping I could get up in the morning and spot ISON before dawn, but the Houston weather would not cooperate. As evidenced by this amateur photographer, the comet was naked-eye in the right conditions. Anyway, ISON’s story ended shortly after perihelion, where the nucleus seemingly broke up in the extreme heat. The disintegrating rubble pile that emerged from the far side of the sun brightened very briefly, and is now dispersing and dimming, currently at 8th magnitude. As the writers at “Sky and Telescope” joke in their summary: “ISON now ISOFF”.
On December 1st, the Indian Mars orbiter Mangalyaan (now being referred to as “MOM” in all the english language media I follow) completed a successful rocket firing to leave high Earth orbit and go into solar orbit, on its way to Mars in September 2014. MOM is now cruising through interplanetary space behind NASA’s MAVEN orbiter, which successfully launched towards Mars on November 18th. Here’s a shot of MAVEN back in August when it was being readied for launch.
The European Exomars project – which consists of two missions in 2016 and 2018 – has chosen the name “Schiaparelli” for the 2016 lander. Schiaparelli was the Italian astronomer in the late 19th century who mapped Mars (and incorrectly deduced that Mars was covered in canals).
The Mars rover Opportunity (still roving almost 10 years after landing!) has found a winter post. Opportunity will hang out for the next 6 months on a north-facing slope called “Murray Ridge”. Murray Ridge is named after Bruce Murray, an influential planetary scientist from JPL who died earlier this year.
Astronomers have used the Hubble Space Telescope to detect water in the atmosphere of 5 “hot Jupiters” orbiting nearby (in galactic terms) stars. Since the planets are Jupiter-like rather than Earth-like, there is nothing Earth-shattering (or Jupiter-shattering) about the finding. However, future studies should be able to analyze the atmospheres of smaller and smaller worlds, leading us closer to finding a true Earth twin.
There is a new naked-eye nova in the sky. Don’t go running outside expecting to see something as bright as Venus – it is only magnitude ~5 and is not visible from Northern latitudes.
Down to Earth
The Russian space agency and their cosmonauts successfully completed their Olympics PR stunt last week. On Saturday, November 9th, cosmonauts Oleg Kotov and Sergey Ryazanskiy took the 2014 Olympic Torch outside the space station and took some pictures.
After the symbolic handoff in space, the Expedition 37 crew from the Soyuz TMA-09M donned their Sokol spacesuits, climbed aboard their Soyuz, and returned to Earth early on Monday, November 11. Congratulations to Nyberg, Parmitano, and Yurchikhin on a great mission, and congratulations to the Russians on a successful orbital Olympic relay. Hopefully our space programs will get a bit of a PR boost as a result.
In heavier news, two space industry workers at the Plesetsk Cosmodrome in Russia died earlier this month in a propellant tank accident.
Two veterans of the Soviet space program died in the last month. First, Dmitri Zaikin, selected in the first class of Cosmonauts in 1960, died at 81. Zaikin never flew in space desite a long career in the program and being assigned as backup Voshkoh 2 commander. Second, Alexander Serebrov, from the second generation of cosmonauts, died at 69. Serebrov logged over a year in space on three separate missions, including flights to Salyut and MIR space stations.
The European Space Agency’s GOCE (Gravity field and steady-state Ocean Circulation Explorer) satellite recently ran out of fuel and crashed back to Earth, after a reportedly successful 4 year mission. Here is a cool picture of its re-entry over a remote part of the Atlantic OCean near the Falkland Islands.
On November 12th, Russia launched a satellite aboard a Proton Breeze-M rocket – the same type of rocket that crashed spectacularly back in July. This marks 3 launches since the crash, which is good news for the ISS program, which is supposed to receive a large new module called MLM aboard a Proton rocket.
In other launch news, SpaceX is scheduled to launch another one of their upgraded Falcon 9 version 1.1 rockets on November 25th, this time from Florida.
Around the Solar System
Continuing the launch news, NASA’s MAVEN Mars orbiter is set to launch on Monday, November 18th.
Mars rover Curiosity spent a bit of time in Safe Mode recently, but is back in full working order.
Comet ISON recently had an outburst and is now as bright as 5.5 magnitude. This should be visible with naked eye for people in dark sites (like my hometown Waikoloa, Hawaii) or keen observers with binoculars or telescopes in less dark areas. Keep in mind that there is a full moon late this week, however. Here are some helpful charts from EarthSky on how to find the comet. The comet is up in the early morning, as it is heading towards perihelion (closest point to the sun) in November 28. Most people are hoping the comet will be even brighter when it emerges from around the sun in December.
Because it’s Cool
XKCD takes a new tact on an old saying about space and perseverance.
Retired ISS Commander Chris Hadfield is now charging full into his book tour to promote his memoir-slash-self-help book An Astronaut’s Guide to Life on Earth. I have been thoroughly enjoying his short videos promoting himself and his book. I think he is fitting into his post-space career very well. Check it out.
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.
Down to Earth
As most everyone is very aware, the US Congress did not come to a budget agreement for Fiscal Year 2014 before the calendar rolled over last week, so all parts of the US federal government that are affected by annual congressional discretionary spending have been shut down. This includes NASA. Some critical mission operations are continuing, including ISS operations and most active planetary exploration missions still have their control rooms staffed. The theme however is that anything not directly related to “real-time” operations has been halted. For the first few days this included work on missions in the pre-launch phase of the mission. Luckily for the MAVEN Mars orbiter, the next probe to launch to the red planet, they were able to get a special exemption so that they won’t miss their launch date this coming December.
The local government near Brownsville, Texas has agreed on how to handle temporary beach closures to allow for rocket launches, if SpaceX was to build a new commercial launch site near the Texas-Mexico border. The new legislation is not technically an approval of beach closures for this purpose, but is one step closer and should continue to drive SpaceX to pick Texas for their new launch site.
Ten year’s after China’s first manned spaceflight the CNSA is talking publicly about training astronauts from other nations. So if you got rejected from NASA’s class of 2012 last year, maybe you will have better luck through this alternate means.
Or if you cannot get a passport to one of the nation’s that may partner with China, perhaps you should audition for NBC’s planned show “Space Race”, a reality show in which contestants can win a free ride to space on Virgin Galactic’s SpaceShipTwo. Neat – but not for me.
Last Thursday, the critically acclaimed film Gravity was released worldwide, and broke the October opening weekend box office record. I saw it with some friends at the first show at the nearest theater to NASA JSC, and was thoroughly entertained. The film is visually stunning and emotionally thrilling – go see it. It keeps an intense tempo with only a 90-minute run time (interestingly, the length of the orbit of the ISS, and an important time in the plot of the film). I am not going to post a bunch of links to reviews about the film because they are likely to be spoiler-ridden. You will enjoy this movie. Go. The trailers even give too much away. Just Go.
The anticipated test launch of SpaceX’s new Falcon 9 version 1.1 rocket took place on September 29th and delivered the Canadian payload CASSIOPE to its intended orbit. This is exciting and important news for the future of the company and their cargo contract with NASA. Unfortunately, one mission objective – to relight the second stage after shutdown – was unsuccessful. The company believes they can fix the anomaly before the next flight.
On the same day as the Falcon 9 rocket launch, the Cygnus spacecraft from Orbital Sciences finally rendezvoused successfully with the ISS, marking a big milestone for that company as well. Their next mission is tentatively scheduled for December, and would be the first official cargo mission of their contract.
Around the Solar System
Late in September, NASA finally declared the Deep Impact/EPOXI mission officially dead. After many weeks this summer of trying to regain communication.
NASA officially announced some scientific results from the Mars rover Curiosity which indicate there is little to no methane in the Martian atmosphere. The data seems robust, given that it comes from a sophisticated laboratory directly sampling the atmosphere for several months, but it contradicts previous intriguing science that pointed to an unexplained high level of methane in the atmosphere of Mars. This previous data had led some discussion about whether it could be a by-product of currently active Martian life. The press release from NASA offers no explanation of why the Curiosity data and the previous data (from powerful Earth-based telescopes and Mars orbiters) do not agree. I am not convinced that there isn’t something else going on here besides “Mars has no methane”…
NASA’s new lunar probe, LADEE, achieved lunar orbit yesterday, October 6. Let the science begin!
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!
Because it’s cool
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.

Virgin Galactic has hired two new pilots, including former Space Shuttle Commander and Navy TOPGUN pilot, Frederick “CJ” Sturckow. Awesome!
At the Kennedy Space Center’s new visitor center, the payload bay doors were opened on Space Shuttle Atlantis, which is slated to go on display this summer.
In honor of the new Star Trek movie, here’s something that has nothing to do with space at all. But it’s funny.
A lot has happened at the space station in the past week and a half! Apart from Soyuz TMA-07M returning to Earth on Monday, May 13…
…on Thursday, May 9, in the morning, (while I was working in the Flight Control Room) the astronauts noticed some mysterious debris floating outside the space station…
…which led to an emergency spacewalk to fix a leaky coolant pump only two days later.
For more information, check out my friend and colleague, Anthony, talking about the space station quick fix.
Chris Hadfield’s return to Earth marks the end of a very successful mission that was more than just a typical ISS expedition. Commander Hadfield reached out to people through social media more than any astronaut before. Here is a small “greatest hits” list of some of his photography. But for me, even better than all the pictures from his mission, was the way Hadfield seamlessly connected his love of music to space. Check out this music video he released just hours before coming home last week.
In less successful orbital news, the Kepler Space Telescope – NASA’s planet-finding spacecraft – seems to be in trouble. On May 15, NASA announced that a second of Kepler’s four reaction wheels may be failed. Kepler needs 3 reaction wheels to accurately point the telescope for precision science measurements. If they cannot recover the lost reaction wheel, Kepler’s mission is effectively done. Kepler has been able to discover thousands of planets in our galaxy (most still being officially “confirmed”) but it easily has thousands more left to discover. Save Kepler!
Around the Solar System
In only one day last week, the sun emitted three X-class solar flares (X-class is the biggest class of solar flare, but just like the earthquake scale, an X10 is significantly bigger than an X2, so it’s all relative). Welcome to solar maximum! If you live somewhere where you can see it, there should be some good aurora to see this year.
Remember that rover on Mars? No, not the bigger shiny new one, that one on the other side of the planet – Opportunity. The plucky rover that could just hit a distance record for NASA set by the Apollo 17 moon rover in 1972. Back in 1972, Eugene Cernan and Harrison Schmidt drove their lunar rover 35.74 km in just a few days. After almost 10 years on Mars, Opportunity just broke that record this week. Also, there’s still the Russian moon rover Lunokhod 2 which drove 37 km in 1973. Opportunity still has a ways to go. But it is amazing that she is still going at all!
Down to Earth
Earlier this month, the White House released their proposed federal budget for fiscal year 2014. Which includes an allocation of $17.7 billion for NASA. Much has been said about the budget already – but the focuses seem to be on the $200 million cut from planetary science and the proposal to start planning an asteroid retrieval mission. Yes, you read that right, the idea is that NASA will send a robotic mission to find a worthy asteroid to drag back to cislunar space (that’s fancy space talk for bringing it as close to Earth as the moon). This may be the direction, focus, and “mission” that many have been saying was lacking from NASA’s portfolio since the cancellation of Constellation and the Space Shuttle. It is far too early to know what will come of it, at least until the mission starts being paid for in 2014. Personally, I think the idea makes sense and is exciting… more thoughts on this in a later post.
In truly down to Earth news, the ambitious Thirty Meter Telescope project received a permit to begin construction atop Mauna Kea in Hawaii. They project plans to begin construction in early 2014. the Thirty Meter Telescope (or TMT) will have almost 10 times the light gathering area of the Keck telescopes, also on Mauna Kea. TMT is going to be an amazing tool for astronomers. It should be able to look “further back in time” and see aspects of the beginning of the universe as well as be an awesome exoplanet finding tool, among many other science applications.
The Navy has announced they will be naming a new research vessel after Sally Ride (first American woman in space).
Virgin Galactic has been busy doing glide flights of SpaceShipTwo, getting ready for their first powered flight this year. In their most recent flight last week, the engine had a “cold flow” test – they flowed some propellant through the engine but did not ignite it.
Boston.com’s “The Big Picture” blog has a nice photo essay of two different Mars analog missions going on here on Earth.
After a planned launch this past Tuesday was delayed, today Orbital Sciences is going to attempt the maiden flight of the Antares rocket, which is planned to take the Cygnus freighter on resupply flights to the ISS. The launch is planned for 5 PM Eastern today (Saturday, April 20). If you read this in time, you can follow along at Spaceflight Now’s mission status center.
Around the Solar System
The Mars rover Curiosity went into hibernation starting on April 4 for the “solar conjunction”. This is the period when Mars is behind the sun as seen from Earth, making it difficult to communicate with probes at the red planet.
The Lunar Reconnaissance Orbiter was able to spot the fresh craters left by the GRAIL missions two probes that crashed into the moon last year (on purpose).
Some Mars enthusiasts from Russia have been scouring Mars Reconnaissance Orbiter images to look for the lost Mars 3 lander that the USSR sent to Mars in 1971. They seem to have found it!
NASA has announced two new missions in the agencies Astrophysics Explorer Program. Two space telescopes, TESS and NICER, are being developed for launch later this decade. TESS (Transiting Exoplanet Survey Sattelite) is somewhat of a successor to Kepler, and will be an Earth-orbiting satellite that hunts for exoplanets. NICER (Neutron Star Interior Composition Explorer) will be attached to the International Space Station and will look at x-ray wavelengths from neutron stars.
It has been a while since I have posted one of my weekly space news links posts. Part of the reason has been a whirlwind move that we (my girlfriend and I) made from our apartment into a new house. We currently don’t have internet, which hampers my blogging a bit. But also, I have been busy at work, including having the privilege of working rather closely on the current SpaceX mission to ISS, which has been exciting. I even attended a joint planning meeting for the mission today to talk about unberth and departure of the Dragon capsule on March 25th, which I will get to support from the Mission Control Center.
Down to Earth
It’s official. As of late last month, the US House of Representatives finally passed a bill to rename the Dryden Flight Research Center in California the Neil A. Armstrong Flight Research Center. The proposal still needs to be approved by the Senate.
An international research team working in Antarctica has found an 18 kg meteorite on the ice surface of that barren continent. This is the largest meteorite find in Antarctica since 1988.
Millionaire and former space tourist, Dennis Tito, announced last month that he intends to create a new space “adventure” (not venture) known as Inspiration Mars. The intent of the project is to send humans (ostensibly a single married couple) on a circum-Martian flight that would take about 500 days. The mission would not involve a landing on the planet, due to cost and complexity, but would seek to inspire a generation and possibly lead to greater adventures (and ventures) in the future. Color me skeptical, but I hope they can do it! Fundraising will be a challenge.
Here are some helpful ideas of how Inspiration Mars might be able to generate revenue to make their mission a success.
SpaceX did another hover test of their huge Grasshopper vertical landing test rocket. Cool stuff.
On March 1, SpaceX successfully launched another Dragon cargo craft to ISS on the first attempt.
SpaceX had some issues with their propellant system that delayed their spacecraft’s arrival at ISS by a day. Dragon arrived with no problems on Sunday, March 3, after many meetings to discuss the issues and agree to a replan. I was working in the Houston Mission control Center that weekend and was impressed to see the machine of mission operations chugging away to produce such a quick turnaround of the timeline!
I enjoyed watching the ISS crew open the Dragon hatch and begin unloading on Sunday evening, which I already wrote about in a previous post.
Around the Solar System
On Mars, the Curiosity rover is having some unknown computer memory issues. On February 28th, ground controllers intentionally commanded the rover to use the backup computer, which put the rover into safe mode (coincidentally, on the same day that SpaceX’s Dragon capsule was having issues). The rover is currently functioning while teams back on Earth prepare to send software “patches” to the rover later this week.
NASA’s Van Allen Probe mission has discovered a third distinct radiation belt around Earth.
This week, the comet panSTARRS is making an appearance in the Northern hemisphere’s skies. This is one of the two comets (the other being comet Lemmon) that were supposed to make a splash this year. PanSTARRS has not turned out to be dimmer than hoped, but still worth looking for. The comet just passed the sun and is coming around the other side, which is why it is fading out of peak brightness while also creeping higher above the horizon after sunset. I was able to find panSTARRS with my binoculars this evening and she is definitely pretty, if small.
Speaking of comets, a newly discovered comet, named Siding Spring, is predicted to have a very close approach of Mars (not us, phew!) in late 2014. The uncertainty in the orbit leaves the possibility open that the comet make actually impact Mars. This would be a bad day for Mars and our spacecraft stationed there. Phil Plait explores the possibility of destruction, while Emily Lakdawalla considers the more benign possibility of a nice meteor shower.
