Some unusual commercial caves
A look at some truly different commercial caves.
Traffic and more roads
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.

The sponge-like Saturn moon
The sponge-like Saturn moon. Key quote:
Hyperion measures about 250kms across; it rotates chaotically and has a density so low that it might house a vast system of caverns inside.

Northern Lights
An evening pause: When the Sun gets active, such as the solar flare of February 15, 2011, the sky in the high latitudes gives us the world’s best light show.
The caves of Copernicus
and the Ocean of Storms
The discovery of new caves on the Moon keep coming. Today I have two new stories. The first is a discovery by professional scientists of a giant lava tube cave in the Oceanus Procellarum or Ocean of Storms. The second is the detection of a plethora of caves and sinks on the floor of the crater Copernicus, found by a NASA engineer who likes to explore the gobs of data being accumulated by Lunar Reconnaissance Orbiter and made available to all on the web.
The image below of the Moon’s near side, taken by India’s Cartosat-2A satellite and taken from the science paper, shows the location of lava tube in Oceanus Procellarum (indicated by the red dot) and the crater Copernicus.
First the professional discovery. Yesterday, the Times of India reported the discovery of lava tube more than a mile long on the Moon. I did not post a link to the article because I didn’t think the news story provided enough information to make it worth passing along. Today however, fellow caver Mark Minton emailed me the link where the actual research paper could be downloaded [pdf]. This I find definitely worth describing.

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