First spacewalk to replace pump module
The first spacewalk to replace the failed pump module on ISS is finished, and it did not go as well as hoped. The astronauts had problems removing one of four cooling system ammonia lines to the old pump. They eventually succeeded, actually using a hammer to lightly tap the quick-disconnect latch free. They then had to seal an ammonia leak coming from the problematic line. These issues caused them to run out of time, preventing them from removing the old pump and installing the new one. It is expected they will pick up where they left off on the next spacewalk, presently scheduled for Wednesday.

Boeing’s private space plans
Boeing cutting metal on its new capsule
Boeing is cutting metal on own privately funded new space capsule, planned for completion in 2015. Key quote:
“We’re at a point in the development of human spaceflight where there’s a market emerging beyond the ISS, beyond NASA,” John Elbon, Boeing’s vice president for commercial space programs, said in a briefing Thursday. “And that piece of this is really exciting as well.”

SpaceX outlines its plans for beyond Earth orbit
At an aerospace industry conference last week SpaceX outlined the company’s plans for building its own heavy-lift rocket, as well as their long range exploration goals. Key quote from rocket development facility director Tom Markusic: “Mars is the ultimate goal of SpaceX.”

First spacewalk to replace pump module delayed
NASA managers have delayed the first spacewalk to replace the pump module from Friday until Saturday, 7 am (EST), with the second spacewalk now delayed from Monday to Wednesday. This is to give them more time to fine tune their plans.

ISS cooling system failure
More on that failure of the cooling system on ISS. It appears that NASA is gearing up to send two astronauts out for up to two spacewalks to try to fix the problem.

Cooling system failure on ISS
A failure in the cooling system on the International Space Station yesterday has forced the astronauts to shut down some of their systems while ground control troubleshoots the situation.

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.
