Burt Rutan on future of space
At an airshow on Thursday, July 29, in Oskosh, Wisconsin, Burt Rutan, designer of SpaceShipOne, made some interesting remarks about the past and future of private space flight. Key quote:
Rutan said NASA should give 10 to 15 percent of its budget to new space companies like Elon Musk’s SpaceX without regulating how to spend the money. “That would allow them to not (have to) beg for commercial investment, while still working in an entrepreneurial mode.”

Poor leadership by Obama on NASA
Glenn Reynolds of Instapundit today said the following (in recognizing Jeff Foust’s op-ed for Technology Review):
CONGRESS BLOWS IT: Commercial Spaceflight, We Have A Problem. Congress will always choose short-term pork over long-term development unless there’s strong Presidential leadership. But while the Obama space policy is good, the White House hasn’t provided the kind of legislative push it takes to make it work. Without strong leadership, a good policy will always lose out to pork.
Didn’t someone say this already? In fact, didn’t that someone say this more than once?
Russian astronauts lose tools during spacewalk
During a spacewalk at ISS yesterday, two Russian cosmonauts successfully replaced a broken camera and installed new wiring for the recently added Russian Dawn module. They also lost a washer and an “attachment fixture” used to fasten the wiring in place, both of which were spotted floating away.

GAO rules layoffs legal
The General Accountability Office has ruled that the Obama administration’s decision to require contractors to reserve money for the possible termination of the contract, thereby forcing them to cut back early on the Constellation program, was legal.

Single Rope Techinque — on the Moon
James Fincannon of NASA took the two images of the Marius Hills lunar pit taken at different times by Lunar Reconnaissance Orbiter (which I posted here) and did an overlay so that the shadow produced by pit’s rim could be easily compared with the rim itself (see below). He then did some calculations based on the sun’s angle of light shining into the cave and came up with the following calculations:
I estimate it is 60 meters from rim to bottom. The floor is flat below the surface. The rocks on the flat surface below ground are in stark relief (hard shadows) compared to above ground due to the sun coming only at one angle while above ground the albedo/reflections makes for soft shadows at this high sun angle (65 deg elevation). I cannot tell if the black portion of the combo image is a slope or more flat floor. Need a different high sun angle or azimuth to fill that in. Still I like the general pattern of the rim matching the shadow on the floor, although the image I found originally has that edge of the cave rim in shadow for a large extent.
A 60 meter drop is about 200 feet deep. This result is reasonably close to the depth estimated by Japanese scientists, 88 meters or 288 feet, based on images of the same lunar pit taken by their Kaguya probe.
Knowing the approximate depth of the entrance pit raises the much more important question: How will future lunar explorers to get to the bottom of this pit? It is ironic » Read more
ISS and Chinese satellite debris
Russian mission control has indicated that the debris left over from destruction of a Chinese satellite in 2007 poses a “danger” to the International Space Station. Key quote from a Russian official:
“If the calculations show that the debris is approaching the station at an unacceptably close range, the six astronauts will receive the order to take shelter in the two Russian Soyuz spacecraft which are docked with the ISS.”

Space war update
This Orlando Sentinel analysis of the various Congressional NASA budget proposals working their way through the House and Senate right now concludes, as I have been saying for months, that the future for NASA is not good. Key quote:
The plan orders NASA to build a heavy-lift rocket and capsule capable of reaching the International Space Station by 2016. But it budgets less money for the new spacecraft — about $11 billion during three years, with $3 billion next year — than what the troubled Constellation program would have received. That — plus the short deadline — has set off alarms.

House committee adds extra shuttle flight
The space war continues. The House Committee of Science and Technology has amended its budget proposal to include an extra shuttle flight, making its proposal match the Senate’s proposal in at least this one way.

Russians reveal new spacecraft
The Russians unveiled today a new proposed replacement for their Soyuz capsule, capable of carrying six astronauts into orbit. Interestingly, the design does not use parachutes to land, but solid rocket engines.

Senate moves towards House NASA plan
In a blunt rejection of the Obama proposals for NASA, the Senate Appropriations Commerce, Justice, and Science Subcommittee today reworked the NASA plan — handed to them last week by the committee that authorizes NASA’s budget — so that it more closely matched the House version. These changes cut in half the money for private commercial space while adding $3 billion to continue the development of the Orion capsule and the heavy lift version of the Ares rocket.

The space war heats up
It appears the space war is heating up again. This analysis of the NASA authorization legislation issued by the House yesterday notes that it has serious differences with the Senate bill. The article notes that the House bill does not fund an additional shuttle mission while insisting that the government continue the construction of some variation of the Orion capsule and Ares rockets. See also this article from the Orlando Sentinel.

House releases their text of NASA budget
The House Committee on Science and Technology has released the text [pdf] of its NASA reauthorization bill. The committee’s short thumbnail description of the language suggests it is similar to the Senate language. A quick scan of the text also suggests this as well. I hope to take a closer look at both the Senate and House bills later this week and then give my take on both.

John Glenn meets with Obama
John Glenn is meeting with President Obama today. Considering Glenn’s opposition to Obama’s plans for NASA, I suspect he is going to spend some his time lobbying Obama about changing those plans.

Senate deal for NASA
More coverage describing today’s Senate committee vote on the 2011 NASA budget. Interestingly, the Commerce committee and a number of its members have each issued their own press releases. I get the feeling they are trying to convince us they have acomplished something. Here are two from the chairman and ranking member:

compromise approved by Senate panel
Keith Cowing at NASAWatch reports in detail about the unanimous approval of the amended Senate budget for NASA. The final budget appears to have raised the funding for commercial space development to match the Obama request, while adding one more flight to the shuttle schedule and mandating an immediate start of work on some sort of heavy-lift rocket.

The space war continues. Now some astronauts chime in.
The space war over NASA’s future continues. Now 24 former astronauts have written a letter to Senator Barbara Mikulski (D-Maryland), endorsing the idea of allowing the private commercial industry to take over the manned space program of the U.S.

Draft version of Senate NASA budget released
A draft version of Senate’s NASA budget has been released. More commentary to come.
Update. From what I can tell by a quick scan through the actual proposed legislation [pdf], the Senate will give the administration most of the money it wants for commercial space, but also demand that it start work on a heavy-lift replacement of the shuttle immediately, including the full size version of the Orion capsule. However, the language requiring this latter action is very vague (“as soon as possible after the date of the enactment of this act”) and leaves the administration a great deal of wiggle room. From my experience, this means that Congress is trying to create the illusion that it has done something, but is basically leaving the decisions to the administration.
The draft language does forbid any contracts being issued for any new private commercial crew services until the 2012 year, which suggests that Congress wants NASA to focus on the Orion capsule and heavy lift option first. However, to me this merely means the Obama administration is being given the option to stall for a year and then come back again later with the same proposals it offered back in February of this year. That the draft legislation also gives NASA 120 days to put together its plan for its heavy-lift program only increases my doubts about Congress’s seriousness.
Overall, this legislation only confirms my worst fears. If passed as is, both the new private commercial space ventures as well as the government space program will suffer.
WhiteKnightTwo trip logs
Scaled Composites has posted the full test flight log for all of WhiteKnightTwo’s test flights, through July 1, 2010. The logs strongly suggest that the company is moving quickly towards its first full flight of SpaceShipTwo.
