The image to the right was taken by Mars Reconnaissance Orbiter, with the white arrow showing the Mars rover Opportunity perched on the rim of Endeavour Crater.
The rover’s scientists hope that the rocks found on the crater rim, dredged up from deep below when the crater impact occurred, will be the oldest rocks so far touched on the Martian surface, and thus give them a peek at ancient Martian geology.
Proposed changes in computer hardware specifications may make it impossible to run free operating systems such as Linux.
The extension of Microsoft’s OS monopoly to hardware would be a disaster, with increased lock-in, decreased consumer choice and lack of space to innovate.

Blurred vision is now considered a serious risk for astronauts who spend months in space.
According to one NASA survey of about 300 astronauts, nearly 30 percent of those who have flown on space shuttle missions – which usually lasted two weeks — and 60 percent who’ve completed six-month shifts aboard the station reported a gradual blurring of eyesight.
This story is a followup on information contained in an earlier National Academies report on astronaut staffing.

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.
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.
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.”
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:

The story behind the Italian prosecution of six scientists and one government official over their failure to make an earthquake prediction.
As is usual in these kinds of stories, things are more complicated than they appear at first glance.
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.
A private Japanese weather company plans to launch a satellite to track Arctic ice for use by shipping.
The satellite will transmit images and information about sea ice in the Arctic Ocean. Weathernews will combine the information with available data on sea currents, weather and wave height to provide consumers with a finished product enabling safe navigation along the northern route.
Though I know most people are skeptical of this idea, I think that all weather information should be gathered and sold by private companies, as Weathernews is doing above. For example, the Weather Channel makes its money providing weather information to the public. If they didn’t get the satellite data free from NOAA weather satellites, they would have every reason to launch their own satellites.
Two stories, one from AP and the other from Florida Today, say that NASA will announce today the design of its heavy-lift rocket, mandated by Congress and estimated to cost around $35 billion. Here is NASA’s press release. To me, this is the key quote (from AP):
NASA figures it will be building and launching about one rocket a year for about 15 years or more in the 2020s and 2030s, according to senior administration officials who spoke on the condition of anonymity because the announcement was not yet made. The idea is to launch its first unmanned test flight in 2017 with the first crew flying in 2021 and astronauts heading to a nearby asteroid in 2025, the officials said. From there, NASA hopes to send the rocket and astronauts to Mars — at first just to circle, but then later landing on the Red Planet — in the 2030s. [emphasis mine]
In other words, after spending $1.7 on the National Space Plane, $1.2 billion on the X-33, $1 billion on the X-34, $800 million on the Space Launch Initiative, and finally, almost $10 billion on Constellation, none of which ever flew, NASA is now going to spend another $35 billion on a new rocket that won’t fly for at least another decade.
To be really blunt, this new rocket, like all its predecessors, will never fly either. It costs too much, will take too long to build, and will certainly be canceled by a future administration before it is finished. It is therefore a complete waste of money, and any Congress that approves it will demonstrate how utterly insincere they are about controlling spending.
A clarification: Some of the $35 billion mentioned above has already been spent for the Orion capsule. This however still does not change any of my conclusions.
Astronomers plan one last close look at 1,900-foot-wide asteroid before sending a space probe there to collect samples.
Discovered in 1999, the OSIRIS-REx target asteroid, designated 1999 RQ36, nears Earth once every six years. During the 2011 closest approach in early September, it will be 10.9 million miles (17.5 million kilometers) away. In 1999, closest approach was 1.4 million miles (2.3 million kilometers).
Strangely, the article above never mentions the fact that 1999 RQ36 has 1 in a 1000 chance of hitting the Earth in 2182, which to my mind is the primary reason for studying it.
