Akatsuki’s engine too damaged to put the probe into Venus orbit in 2015
The engine of Japan’s troubled Venus probe, Akatsuki, has been found too damaged to put the probe into Venus orbit.
JAXA conducted a test ignition of the probe’s main engine on Wednesday to prepare for another attempt to send it into orbit in 2015. But the thrust produced was only one-eighth the amount anticipated, the space agency said. The damage the engine suffered last December when JAXA ignited it in the initial attempt to send the probe into orbit around Venus appears to be more serious than thought, JAXA said.
Soyuz crew returns safely to Earth, despite radio problems
One of the two three-man crews on ISS have returned safely to Earth, despite an unexpected communciations blackout during their descent.
In related news, the Russians have slightly delayed the launch dates for the next manned flights to ISS, which also means that the next test flight of Falcon 9/Dragon will have to be delayed until 2012. Moreover, the Russians are once again balking at allowing Dragon to dock with ISS on this first flight.
Walking on water
An evening pause: Walking on water. As the youtube website explained, “They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid.”

Questions about White House pressure for campaign donor in GPS controversy
A four-star Air Force general told a congressional committee last week that the White House pressured him to soften his testimony concerning the military’s opposition to the technology being used by the broadband company Lightsquared– a major Democratic campaign donor — because it interfered with GPS signals.
In a related update, LightSquared boss said Wednesday that the company is near an engineering breakthrough that will solve the technical issues that worry GPS users.
Another look at the cost of building NASA’s heavy lift rocket
Clark Lindsey takes another look at the cost for building the Congressionally-mandated heavy lift rocket, what NASA calls the Space Launch System and I call the program-formerly-called-Constellation. Key quote:
Finally, I’ll point out that there was certainly nothing on Wednesday that refuted the findings in the Booz Allen study that NASA’s estimates beyond the 3-5 year time frame are fraught with great uncertainty. Hutchison and Nelson claimed last week that since the near term estimates were reliable, there’s no reason to delay getting the program underway. That’s the sort of good governance that explains why programs often explode “unexpectedly” in cost after 3-5 years…
In other words, this is what government insiders call a “buy-in.” Offer low-ball budget numbers to get the project off the ground, then when the project is partly finished and the much higher real costs become evident, Congress will be forced to pay for it. Not only has this been routine practice in Washington for decades, I can instantly cite two projects that prove it:

Virgin Galactic aims for its first launch of SpaceShipTwo within a year
Virgin Galactic expects to make its first launch of SpaceShipTwo within a year.
“The mother ship is finished… The rocket tests are going extremely well, and so I think that we’re now on track for a launch within 12 months of today,” [Richard Branson] told CNN’s Piers Morgan late Wednesday.
