Detector Array Deterioration Poses New Problem for JWST

9:27 pm

More problems for the James Webb Space Telescope: The detector arrays for several instruments are deteriorating, even as they sit on the shelf. And remember, the 2014 launch date is probably going to be delayed until 2016. Key quote:

“As you get further and further out with [the launch date], it really raises questions about how far down the [integration and test] process you go for the instruments … and how long you have to store all that before you actually launch,” [Webb program director Rick Howard] told the NASA Advisory Council’s astrophysics subcommittee during a Feb. 16 public meeting here. “And that just makes everybody even more nervous about this problem than anything else.”

Scientists Steer Car With the Power of Thought

5:15 pm

What could go wrong? Scientists have developed technology allowing someone to steer a car by thought alone. Key quote:

“In our test runs, a driver equipped with EEG sensors was able to control the car with no problem — there was only a slight delay between the envisaged commands and the response of the car,” said Prof. Raúl Rojas, who heads the AutoNOMOS project at Freie Universität Berlin.

House cuts off funds to IPCC

9:18 pm

Listen to the squealing: Scientists criticize the House vote to cut off funds to the IPCC. Key quote:

Without the federal support, [Stanford ecologist Chris Field] said, “We’d have no ability to organize meetings, we’d have no ability to coordinate chapters.”

In other words, no more jaunts to Cancun in the midst of winter. What a shame!

Considering the insincere effort of the IPCC and its scientists to correct its numerous errors, as well as their admitted political agenda, it seems completely appropriate to stop funding it with U.S. tax dollars. If these environmentalists want to issue a report, they should pay for it themselves.

More Webb budget troubles

10:56 am

According to its manager, the budget troubles of the James Webb Space Telescope will likely keep it on the ground until 2016.

This is terrible news for space-based astrophysics. Until Webb gets launched, NASA will have no money for any other space telescope project. And since all the space telescopes presently in orbit are not expected to be operating at the end of the decade, by 2020 the U.S. space astronomy program will essentially be dead.

Then again, there is the private sector, as Google Lunar X Prize is demonstrating.

A potential landing site for next Mars rover

3:32 pm

This week’s release of cool images from Mars Reconnaissance Orbiter included the color image below of a region on the floor of Holden Crater, one of the four possible landing sites for Curiosity, the Mars Science Laboratory planned for launch later this year. (If you want to see the entire image at higher resolution, you can download it here.)

Two things that immediately stand out about this image (other than this looks like an incredibly spectacular place to visit):
