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
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.

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!

One of the three original founders of the Planetary Society, Bruce Murray, passed away on August 29th. Murray was director of NASA’s Jet Propulsion Laboratory during the Viking and Voyager era. He started The Planetary Society with Lou Friedman and Carl Sagan in 1980. If you are a space enthusiast and you are not yet a member of the Planetary Society, you are missing out. Check out their website and weekly radio show.
Last week three ISS crew members returned to Earth, ending Expedition 36. Chris Cassidy, Pavel Vinogradov, and Alexander Misurkin landed on September 11 in Kazakhstan. Next week a new crew will launch and dock on Wednesday, September 26.
Not Quite in Orbit
It seems cosmonaut Yuri Lonchakov – who was in space on Expedition 18 when I started working at JSC – has decided to retire from the space business. He had been in training to fly as commander of Expedition 44 in two years, which is what makes the departure somewhat confusing. However, as NASA Watch points out, he has been in the corps for a long time, with his first flight over a decade ago on STS-100. Everyone has to move on some time.
Last post I wrote about the second powered flight of SpaceShipTwo on September 5, and included some cool footage of the flight from the ground. Well, since then, Virgin Galactic released this view from onboard the spaceplane. Very cool (via Ubergizmo).
Last week on the 12th, SpaceX did a “static firing” (which means the rocket didn’t go anywhere) of the new Falcon 9 rocket on the pad at Vandenberg Air Force Base in California (here’s a Google Maps link). Unfortunately, they saw some anomalies and the test launch was delayed from the planned date of the 15th. According to Elon Musk, they hope to launch at the end of the month.There was a problem connecting to Twitter.
The new rocket is the Falcon 9 version 1.1. As you can see in the graphic below (from Wikipedia), version 1.1 is a significant visual upgrade from the existing Falcon 9. In addition to the payload faring and longer fuel tanks – making it taller – they are upgrading the Merlin engines that power the first stage. All future Falcon flights are supposed to transition to this rocket after the tests, including NASA cargo flights to ISS. So here’s hoping for a good launch in a week or two!
This morning at 10:50 AM Eastern, the Antares rocket carrying the first Cygnus cargo craft launched from Wallops Island, Virginia on the way to ISS.
The flight will bring Cygnus up to ISS for rendezvous this coming Sunday, September 22nd. My favorite part of the launch is this clever sign near the launch pad that made for a good photo op. Or maybe this bald eagle who had a front row seat is cooler?
As of this writing, the spacecraft has already done initial checkouts, with more ongoing.
In a nice double-whammy, there was also a big rocket launch from Florida early this morning. A United Launch Alliance Atlas V rocket launched an Air Force satellite before dawn at Cape Canaveral.
I was intrigued by this article at the Huffington Post about NASA’s radiation limits on active astronauts. Because of differing risks for cancer between genders, women have lower allowed limits of radiation, meaning they can’t fly as many days in space.
Around the Solar System
In somber news, mission managers of the Deep Impact/EPOXI mission announced earlier this month that they have been out of contact with the spacecraft for about a month. Flight controllers have indications that the onboard computer had a glitch and is now likely spinning out of control, which is why they can’t get commands uplinked to correct the problem – the communications antenna is not pointing towards home. The worry is that if it spins out of control for too long, the batteries won’t get charged from the solar arrays and the spacecraft will die.
EPOXI was launched as Deep Impact in 2005 and has had a very successful mission so far, with the rendezvous and impact of comet Tempel 1 and then years later the dramatic flyby of comet Hartley 2.
The biggest space news so far this month, at least that the public has noticed, was the official announcement by NASA that the Voyager 1 spacecraft has entered interstellar space. Some people were incorrectly reporting the announcement as “Voyager 1 has left the solar system” which makes me roll my eyes (see below). Phil Plait of Bad Astronomy covers this topic well.
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.

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.

Chris Hadfield, recently returned ISS commander and now retired astronaut, has announced he will be releasing a book titled “An Astronaut’s Guide to Life on Earth”. It’s not clear yet if the format will be that of a memoir or something else.
John Anthony Llewellyn, who was selected as an astronaut in 1967, died earlier in July. He was 80 years old. Mr. Llewellyn was one of the scientist-astronauts of the 6th NASA group, and resigned from NASA before flying to space.
Its time for the NASA budget battle. Congress has been working on the authorization acts for the 2014 federal budget. The proposal from the Senate has NASA being funded at $18.1 billion, or even higher than the executive branch requested ($17.7 billion). However, the House of Representatives has something different in mind, and is proposing a budget as low as $16.6 billion, which is less than the White House requested. It would take a miracle for this to get resolved before the fiscal year starts.
The Apollo rocket parts being recovered from the Atlantic by Jeff Bezos have been identified as originating from the rocket that sent Apollo 11 to the moon.
Lots of news from ISS and the world’s active space programs in the past few weeks.
First, NASA conducted two spacewalks from the US airlock on the ISS. The first, on July 9th, was successful. Luca Parmitano and Chris Cassidy did maintenance outside for a solid 6 hours. However, if you google “July 2013 spacewalk” you won’t get any results for the July 9th EVA, because just a week later the two astronauts went out the door again, and were not as successful. The Tuesday, July 16 spacewalk ended after only 92 minutes because of water collecting in Parmitano’s helmet. It seems his spacesuit, or EMU, had some kind of cooling system leak. NASA is still investigating to figure out what exactly is broken. There are 3 NASA spacesuits on ISS, so they have a backup if an emergency spacewalk is needed.
In Kazakhstan on July 2, a Russian Proton rocket crashed spectacularly just seconds after launch.
The rocket is the same kind that sometimes takes large ISS components into orbit – such as the MLM, or Nauka, module that is manifested to launch later this year. The rocket was carrying several Russian GPS satellites (known as Glonass). Obviously all the payload was lost.
Check out the shockwave hitting the cameraman in this amateur footage of the crash.
The official investigation commission in Russia has publicly announced their preliminary findings. It appears some sensors were improperly installed. Oops.
Meanwhile, the Kepler Space Telescope team is working towards attempting recovery of one of her failed reaction wheels – which are currently preventing the telescope from doing any more science.

The International Astronomical Union has given names to P4 and P5, the new moons of Pluto discovered by Hubble just over a year or so ago. The new moons will be named Kerberos and Styx, staying with the god of the underworld theme (the other 3 known moons are Charon, Nix, and Hydra).
The IAU named the Pluto moons just in time, because another astronomer looking through old Hubble data of Neptune, found a new Neptunian moon! It will need a name now also…
Curiosity has now roved more than 1 kilometer at Gale Crater on Mars. I wish she would rove faster!
Data from the Hubble Space Telescope (yes, more Hubble!) has identified the color of an alien world. By watching a distant planet “transit” in front of its parent star, the instrument called Space Telescope Imaging Spectrograph was able to figure out that the Jupiter-sized planet is blue. Read Phil Plait’s explanation if you want the details. The color tells us more about the planet – like the fact that the atmosphere is probably full of methane.
Down to Earth
A couple of updates on Space Shuttle artifacts being displayed. First, the original external fuel tank test article was shipped from KSC to the “Wings of Dreams Aviation Museum” in Starke, Florida. Second, the space shuttle Atlantis was “unwrapped” at its new display at the KSC visitor center.
Rumor has it that Virgin Galactic might have their first powered test flight of SpaceShipTwo next week.
The Texas state legislature is a few steps away from approving key measures that would enable SpaceX to build a launch site near the Mexico border outside of Brownsville. This week the Texas House of Representatives approved a bill that would allow closure of state beaches during launches. The bill still needs to go to the State Senate before passing.
Mars One, the… company? … that plans to colonize Mars, has opened up their astronaut application process. What the heck, why not apply?
Orbital Sciences successfully launched their first Antares rocket on April 21st. It was a beautiful launch into a clear blue sky. We look forward to seeing them on ISS in a few months.
Up on the Space Station, two cosmonauts – Pavel Vinogradov and Roman Romanenko – went on a six-and-a-half hour spacewalk to work on some external experiments and also some various maintenance.
On Wednesday, the latest Russian Progress resupply craft launched on its way to ISS. The docking is planned for just a few moments from now, on Friday morning (coverage is live on NASA TV if you catch this post right after it goes up). The Progress will be docking to ISS despite a rendezvous antenna that was unable to fully deploy after launch. The retracted antenna is physically in the way of the docking mechanism, so flight controllers will have to come up with a plan to get the antenna out of the way… or something else. Otherwise the cargo inside will not be accessible. One possibility is to plan another spacewalk after docking to move the antenna.
And on a lighter note, Commander Hadfield talks about barf bags in space.

At Saturn, the Cassini spacecraft has been observing meteors impacting the planet’s rings. Awesome.
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.

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.
Last weekend, the six-man crew onboard the ISS got a special delivery from Earth. The third in what we hope will be a long line of SpaceX Dragon capsules was grabbed by the space station robot arm on Sunday morning. It didn’t take very long after the Dragon was firmly attached for the crew to start working diligently to get the hatches open and get to the cargo inside, even though it was supposed to be partly their day off.
Why the rush? Well if you had only eaten fresh food a few times in the last four months you would be excited too! About 2-4 cargo deliveries will happen during an astronaut’s stay on ISS – so that means you only get to enjoy fresh fruit and vegetables in your diet for a few weeks of your stay.
I was on shift in ISS mission control on Sunday when the crew got the hatch open and you bet they wanted to know where the bags of apples were stored away. Not only did they find the expected NASA manifested bag of apples, tomatoes, and other items, but SpaceX had hidden away a special care package of extra apples and oranges. Their excitement was clear and I’m sure they had a good dinner that night.
What I think comes to light in this case is the interesting economics of supplying a space station, or I suppose any remote operating base. An orange is cheap – your neighbor’s tree might drop some over the fence into your yard and they would never know they were missing nor probably care. But the cost of launching those oranges to ISS makes them worth a lot – not quite equivalent to gold by weight, but getting close. Imagine if the trip to the grocery store cost you 10,000 times more than the groceries themselves? That’s a cost of living that would make even San Franciscans cringe.
This is obviously one important reason that spaceflight is so expensive. By having companies like SpaceX to run supply missions, launch costs can be reduced through efficiency and frequency. But even so, launch costs can only drop by so much. Thus, we will never truly be a spacefaring species unless we learn to be self-sufficient. The European colonies in America only prospered when they learned to live off of the local resources. As long as oranges are worth $2,000, we will be stuck in low earth orbit like some colonists in a coastal fort waiting for the next ship from England.
Someday the lessons we are slowly learning about self-sufficiency on ISS and elsewhere (like bases in Antarctica) will take us outward – but until then I would hate to be the astronauts up there stuck with the guilt of eating a $2,000 orange. What does it feel like to know that so much effort went into getting you just a few bites of fruit?
