Soyuz undocking at ISS delayed
The scheduled return of three astronauts on a Soyuz spacecraft has been delayed tonight because of a malfunction in the docking port.
Update: The return to Earth has definitely been canceled for tonight. The problem was caused when latches on the Soyuz, designed to secure it safely to ISS, refused to release on command. As of 12:43 am the plan was to recycle and try to land on Friday evening.

First tests of beer in zero gravity
Who says space exploration is dead? Sometime in November researchers will conduct the first zero gravity tests of the world’s first beer to be certified for drinking in space. The tests will take place during suborbital flights of what is commonly known as the Vomit Comet. Key quote:
Sampling the beer during weightless parabolas, the flight researcher will record both qualitative data on beverage taste and drinkability and biometric data on body temperature, heart rate, and blood alcohol content.

The United States, as seen from the Moon
On August 9, 2010 the camera on Lunar Reconnaissance Orbiter took some routine calibration images and captured the Earth from lunar orbit, showing the western hemisphere with relatively little cloud cover. The picture below is a tiny piece from that global image, cropped to show the United States. The details are pretty remarkable, considering the distance. You can explore the full global image in detail here.

Earliest Kodak color tests
An evening pause: Though this sequence of shots from a 1922 Kodak test of Kodachrome film (possibly the earliest in existence) is hardly the stuff of drama, it is fascinating nonetheless, as it gives as an honest glimpse into the culture of its time. As you watch the different women pose for the camera, ask yourself: Has anything changed?

Europe to the Moon
Europe to the Moon! The U.S. may no longer have a coherent lunar exploration program, but Europe sees that water at the Moon’s south pole and wants it, awarding contracts today to begin the work of getting a lunar lander there.

First spacecraft to use Earth-Moon L2 point

China continues satellite maneuvers
China is continuing the mysterious maneuvers of the two satellites that might have actually touched earlier this month. Key quote:
The maneuvers, which appear to involve rendezvous operations between the SJ-06F satellite and the more recently launched SJ-12 craft, could amount to practice for space station dockings or coordinated satellite observations from orbit. Few folks would have a problem with that. But they also could be aimed at developing the expertise for lurking near someone else’s satellte and eavesdropping, or even knocking that satellite out of commission in the event of a crisis. That’s the worrisome part.

Building a lunar vegetable garden on Earth
University of Arizona scientists have built a hydroponic lunar vegetable garden on Earth. More information here. Key quote:
The membrane-covered module can be collapsed to a four-foot-wide disk for interplanetary travel. It contains water-cooled sodium vapor lamps and long envelopes that would be loaded with seeds, ready to sprout hydroponically.

Government high speed railroad and elections
The federal government’s very expensive and probably unnecessary project to build a high speed railroad line between two cities in Wisconsin — using stimulus money — is having a significant influence on the elections there. Key quote:
With the U.S. economy in shambles and our national debt strangling the country, it doesn’t bode well for Feingold that he supported the wildly unpopular health-care bill, which [challenger] Johnson wants repealed, as well as last year’s big clunker, the stimulus bill. Feingold’s support for the unfunded and bottomless money pit of [high speed rail] doesn’t appear to be working for him either. If an entrenched insider like Feingold loses, it could have serious ramifications for the future of high-speed rail across the country. [emphasis mine]

Space Makes Polymers Hard
The harsh environment of space, normally hostile to most materials, acts beneficially to cure certain epoxy resins. Key quote:
“You don’t have to take it up there in the shape that you eventually want,” said University of Sydney physicist Marcela Bilek, a co-author of the new study. “You can take something in a packaged form, all folded up, and then inflate it in space and have it cure into a mechanically solid structure.”

The pain of spacesuit gloves
The number one injury reported by astronauts appears to be fingernail and hand injuries resulting from the use of spacesuit gloves. Key quote:
A previous study of astronaut injuries sustained during spacewalks had found that about 47 percent of 352 reported symptoms between 2002 and 2004 were hand related. More than half of these hand injuries were due to fingertips and nails making contact with the hard “thimbles” inside the glove fingertips. In several cases, sustained pressure on the fingertips during EVAs caused intense pain and led to the astronauts’ nails detaching from their nailbeds, a condition called fingernail delamination.

ISS’s life expectancy
Engineers are reviewing the life expectancy of the International Space Station, in light of the desire of politicians to keep it operating through the 2020s. Intriguing quote:
Airlines and airplane contractors commonly inspect aircraft for such fractures, but with the space station out of reach more than 200 miles up, engineers rely on complex models to predict their growth in orbit.

Scientists develop tractor beam
Scientists develop first tractor beam, although it can only move tiny objects less than two yards. Worse, “because this technique needs heated gas to push the particles around, it can’t work in the vacuum of outer space like the tractor beams in Star Trek.”
