The Soyuz capsule, carrying the next crew to the International Space Station, has docked safely with the station.
Engineers now think that a cracked nozzle caused the Japanese probe Akatsuki to miss Venus.
NASA will be conducting tank tests today on the Discovery’s external tank in an effort to find the cause of the recently discovered cracks.
This is more a kerfuffle in the press than a real emergency: for about three hours today Russian mission control had problems communicating with either ISS or the Soyuz spacecraft that is on its way to it. Neither spacecraft was in any danger during the down time.
Virgin Galactic has confirmed the story from Space News that it is part of the crew/cargo proposal that Orbital Sciences submitted to NASA this week.
The image below was produced by Lunar Reconnaissance Orbiter by assembling data from numerous images over six months. The levels of brightness and darkness indicate the percentage of time in which an area is sunlight. The red dot just below the rim of Shackleton shows the approximate location of the south pole.
As you can see, the rim of Shackleton Crater nearest the south pole is illuminated by the sun most of the time, while the nearby crater floor never gets sunlight. This data confirms what Japanese scientists found using their lunar probe, Kaguya. The south pole has the ideal combination of locations with nearly continuous bright sunlight (to provide power) and nearly continuous darkness (where explorers will likely find significant amounts of frozen water), making this is an excellent location to build that first lunar base. And from the image you can see that the Shackleton Crater rim is not the only spot near the south pole with these conditions.
Also, if you look at the close-up image of Shackleton’s rim that I posted here, you will see that there is plenty of room to land and set up residence.
For those that want to relive the experience of success, SpaceX has posted a short highlight video of last week’s successful test flight of Falcon 9/Dragon capsule.
It is difficult to overstate the importance or magnifience of this achievement, accomplished not by a government but by a private company. As SpaceX rightly brags on its website:
This marks the first time a commercial company has successfully recovered a spacecraft reentering from Earth orbit. It is a feat previously performed by only six nations or government agencies: the United States, Russia, China, Japan, India, and the European Space Agency.
What I find even more telling is how quickly SpaceX got this done. The first launch attempt of their first rocket, Falcon 1, took place in March of 2006. About that same time they began work on Falcon 9, and were able to successfully fly its first mission only four years later. Contrast that with NASA. President Bush proposed building a replacement for the shuttle in 2004, and six years later all NASA could do was fly a mockup of Ares I/Orion, not the actual article. And that leaves out NASA’S numerous previous attempts to build a shuttle replacement that spent billions, and never did more than produce pretty powerpoint presentations.
SpaceX’s speed of operation (a sure sign of efficiency) is reminiscent of the early days of the space age. Then, NASA might have laid out the overall plan, but everything was built by private companies, all used to fighting for profits and market share. None could afford a leisurely pace, nor could they afford to do things badly. If they did either, their business would suffer. As a result, the United States was able to go from having no ability to put anything in orbit to putting its first man in space in less than three years, and was able to follow that up with the first manned lunar mission only seven years later.
After a string of failures going back to 2004, the Indian space agency is set to try to launch its most powerful rocket again, this time with its heaviest cargo.
The Air Force has agreed to share the meteorite data its surveillance satellites detect.
Though the article above makes it sound like this data includes a lot of Earth-destroying asteriods, almost all of these detections are of smaller rocks burning up in the atmosphere, information researchers need to produce a more complete census of the solar system.
A software glitch prevented Kepler from making science observations for 13 hours this week.
At least the Russians can still do this: At 2:09 pm (Eastern) today a Russian Soyuz rocket lifted off, carrying the next crew to the International Space Station.
In an article today on spaceref.com “NASA: It’s Our Space Station – Not Yours,” Keith Cowing has some harsh words for NASA and its management of the research on ISS. Based on what he witnessed at a NASA meeting, it appears that NASA wants to retain control over all research on the space station, while denying access to outside other researchers. Key quote:
In addition to prohibiting the ISS National Laboratory contractor from getting its hands on human-based research, Mark Uhran also stated that any proposal that proposed to do anything with spacecraft systems or engineering would be similarly deemed non-responsive. In other words two of the most interesting things you can do on the ISS – the sorts of thing you’d want a larger research base to focus on (assuming you are really interested in outside participation) are off limits due to executive fiat.
Where is NASA’s justification for limiting the ability of the private and educational sectors from making full utilization of the amazing capabilities that are offered by the ISS? Answer: NASA made it up. Truth be known, NASA was dragged kicking and screaming into supporting this National Laboratory concept. Congress had to enact a law to make them do it.
None of this surprises me. NASA is a government agency, and as a government agency it is going to protect its turf, come hell or high water. It is for this reason I think it a bad idea for the new space rocket companies to take any NASA money, up front. If they do, NASA will immediately use those funds as a club to force these new companies to do things as NASA wishes, rather than being free to compete and innovate on their own. In other words, NASA will use the funds to maintain control of all space exploration.
Better the new companies build their rockets and spaceships on their own, and then sell these new inventions to NASA or whoever else wants to use them. Let the profits pay for the work, not the needs and regulations of a government agency.
Not only will this free competiton produce a lot more creativity and innovation, it will almost certainly help to reduce the cost of space travel, as these companies fight to gain market share. And most importantly, it will frame the future exploration of space in the context of freedom rather that a state-run endeavor.
And isn’t freedom the principle that the United States of America stands for?
The Japanese Venus probe Akatsuka might have failed, but its partner, the solar sail Ikaros, continues to function, and remains in contact with its ground controlers, even at a distance of 45 million miles. (The google translation of the daily blog is sometimes spotty (” I will go home 入Rita bath. It will fit your feet smell.”) but still worth reading,)
The largest commercial antenna reflector ever flown in space has successfully deployed in orbit.
In competition with the Orbital/Virgin Galactic proposal I mentioned yesterday, Boeing has submitted its own proposal to provide crew and cargo ferrying service to ISS.
Considering the federal budget debt and the political winds for reducing that debt, I have great doubts the subsidies for these proposals will ever arrive. Nonetheless, with the end of the shuttle program and nothing to replace it, the United States has a serious need for a system to get crew and cargo into space. And in a free society, fulfilling that need means profits, which is why these proposals are beginning to appear, and will get built, regardless of whether Congress funds them up front or later buys the services.
Orbital Sciences and Virgin Galactic have teamed up to propose a four person reusable orbital spacecraft to ferry crews to ISS. Key quote:
The spacecraft, designed to launch atop an Atlas 5 rocket and dock with the international space station, could be ready for test flights as early as 2014. The remotely piloted spacecraft would be able to carry four passengers initially, including three astronauts and one paying ticketholder, though based on market demand the number of private rides aboard the vehicle could grow to two, with four astronaut seats available, sources said. In the works at Orbital for the past year, the reusable spacecraft would be built using existing materials and technologies, employ standard hypergolic propellants and rely on a pusher escape system in the event of a launch mishap, sources said. [emphasis mine]
Note their insistence that they be allowed to fly tourists. This is a major change from how NASA has operated in the past, as a Soviet-style government agency hostile to commercial profits.
Correction: Clark Lindsey notes that the Orbital press release makes no mention of Virgin Galactic, as reported above.
Engineers to the rescue! The Leaning Tower of Pisa no longer leans as much as it used to, but the lean it has is now expected to last for at least another 200 years.
The new colonial movement continues: Brazil successfully launched and recovered a suborbital rocket this past weekend.
The Navy set a new world record with the firing of an electromagnetic railgun on December 10. Though intended as a military weapon Keith Cowing speculates about the railgun’s off-world applications.
The first report is back of the X-37B following the completion of its first flight.
A nano-sized solar sail, built by NASA and launched in mid-November, appears to have been lost. Sadly, this has been the history of almost all solar sail efforts: failure before the sail can even deploy.
The rise and fall of Rocketplane.
A car that runs on air. Literally.
So, what was the top secret payload carried by Dragon on its first orbital mission? SpaceX revealed this secret today: their tribute to Monty Python.
A wheel of cheese.
SpaceX is two for two! The Falcon 9 launch today was a success, and was topped off by the successful return of the Dragon capsule after two orbits.
This is big news. Think about it: a private company — not a government — has designed and built a rocket and capsule, capable of carrying astronauts, and successfully launched both and recovered the capsule. Hot dog! True space travel might very well be around the corner at last.
Sad news: It appears that Japan’s Venus probe failed to enter orbit, and might have flown past Venus.
Update: It is confirmed that the spacecraft flew past Venus. There is a chance Japan could try again, when Akatsuka returns to Venus — in about seven years.
The military’s perspective on the X-37B.
It appears that the next attempt to launch Falcon 9/Dragon is now set for Wednesday.
