Traffic and more roads

8:12 am

Puncturing the myth that more roads mean more congestion Key quote:

Read enough of these studies and you get a sense that much of the induced-demand hubbub is really a sub rosa extension of the war on the suburbs: Stop highway expansion and you can make life miserable enough for the minivan-driving masses that they’ll move out of their gauche “urban-fringe developments” and back to high-density metropolitan cores, where they belong.

In reading the full essay, I was struck by how much the scientific campaign against road construction reminded me of climategate.

10:16 pm

The beer has landed: The first test of space beer in weightlessness has been completed. Key quote:

Astronauts4Hire Flight Member Todd Romberger was selected to perform the flight research. Todd sampled the beer during 12 microgravity parabolas, each reproducing the weightless conditions of space for 30 seconds at a time, and recorded qualitative data on beverage taste and drinkability as well as biometric data to gain a first look at alcohol effects the body.

Two High-priority Climate Missions Dropped from NASA’s Budget Plans

9:33 pm

Two high-priority climate missions dropped from NASA’s budget by the White House. And what’s most amazing: No one’s squealing!

“Removal of these missions was not what we desired and not what the administration desired, but it was a clear recognition and acknowledgement of the budget issues we face as a nation,” [said Steve Volz, associate director for flight programs at NASA’s Earth Science Division]. “It’s cleaner to be allowed to delete the scope that goes along with the dollars than to have to figure out how to do more with less.”

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.”
