Fuel leak on Discovery
Engineers are trouble-shooting a fuel leak on the space shuttle Discovery. At the moment NASA does not expect this to delay the planned November 1 launch.

Two German radar mapping satellites to produce three-dimensional imagery of Earth
Two German radar mapping satellites, flying in orbital formation, are now about to produce the first three-dimensional radar imagery of Earth. Key quote:
The combined mission’s data will produce gridded maps with a spatial resolution of 12 meters, or 39 feet. The maps will show elevation with a precision of less than 2 meters, or 6 feet.

The color of a wind turbine can attract bugs
Scientists have found that the color a wind turbine is painted will influence the number of bugs it attracts, which in turn will influence the number of bats and birds killed by the turbine. The least attractive color for bugs: purple!

A wish list of spectacular future planetary missions
Steve Squyres of Cornell University and the project scientist of the Mars rovers Spirit and Opportunity spoke today at an astrobiology symposium in Arlington, Virginia. He described several spectacular planetary missions that might be flown in the coming decade. All are being considered. None have yet been chosen or funded.
- A mission to grab a sample from a comet and return it to Earth.
- A mission to put a rover or lander on one of the poles of Mars to study the frozen layers of water under the icecap.
- Mars sample return mission. This mission is so difficult and expensive that it probably would be broken down into three parts:
- Two rovers on the surface to gather and cache sample material.
- A lander/rover mission to grab the samples and bring them up to Mars orbit. “Putting into orbit a precious cargo the size of a coconut,” Squyres said.
- A mission to grab the sample cargo in Martian orbit and return it to Earth.
- An orbiter to study both Jupiter and its moon Europa.
- An orbiter to Enceladus, the moon of Saturn, to study the water and organic chemistry in its mysterious plumes.
- An orbiter to Titan, with balloon to probe the atmosphere as well as a “lake lander, a boat” to study Titan’s lakes.
- A variety of landers and rovers to go to Venus. One of the more astonishing mission concepts would land, then take off again to visit different places on the surface.
Squyres is the co-chair of a committee of the National Science Foundation that is right now putting together a decadal survey for outlining unmanned planetary research for the next decade. This survey is expected to be released in March, which is when we will find out which of the above missions the planetary science community prefers.

Last Chilean miner reaches the surface safely
The last Chilean miner has reached the surface safely. Key quote from one of the miners in answer to a question about their future as media stars:
“The only thing I’ll ask of you is that you don’t treat me as an artist or a journalist, but as a miner. I was born a miner and I’ll die a miner.”

The World’s First Everything-Proof Underground Luxury Community
The world’s first everything-proof underground luxury community. Fun quote:
The Barstow bunker was built to withstand a 50-megaton nuclear blast 10 miles away, 450mph winds, a magnitude-10 earthquake, 10 days of 1,250°F surface fires, and three weeks beneath any flood. Vicino says that a soon-to-be-installed air-filtration system will also neutralize any biological, chemical or nuclear attacks. The Barstow branch will stock enough food and clothing to sustain 135 people for at least a year, and in a lifestyle that Vicino describes as compact but luxurious, like being on a cruise ship.

The state of NASA’s commercial crew program. Key quote:
The Obama administration requested $3.3 billion for commercial crew services over the next three years, but a so-called compromise bill forged in the Senate slashed the proposal in half. After months of heated contention, the House of Representatives finally agreed to the Senate authorization bill in late September, calling for $1.6 billion for the commercial program.

X-37B goes missing.
Spaceweather.com noted yesterday that the amateur astronomers have reported the X-37B space plane missing. It did not show up when expected, based on its known orbit. Key quote:
It’s possible that the X-37B has landed. More likely, the space plane has maneuvered into a new orbit and will be recovered again in the nights ahead.
