Very brief descriptions, with appropriate links, of current or recent news items.
During a spacewalk at ISS yesterday, two Russian cosmonauts successfully replaced a broken camera and installed new wiring for the recently added Russian Dawn module. They also lost a washer and an “attachment fixture” used to fasten the wiring in place, both of which were spotted floating away.
The General Accountability Office has ruled that the Obama administration’s decision to require contractors to reserve money for the possible termination of the contract, thereby forcing them to cut back early on the Constellation program, was legal.
A cave exacavation in East Timor has uncovered the bones of the largest rat species on record, weighing over 13 pounds and living approximately one to two thousand years ago. The dig also uncovered 11 previously unknown rat species.
In its first six weeks of observation, the Kepler mission apparently found almost 150 planets similar in size to the Earth. The results, learned by accident because a talk given by one of the co-investigators was posted on the web, have not yet been officially announced because the project scientists feel a need for additional time to confirm them. Many of these so-called planets might turn out to be false positives, so some caution is in order.
It’s not the crime but the cover-up: Michael Mann refuses to answer reasonable questions from a reporter for The Dailer Caller.
Spam is everywhere! Today NASA’s Twitter feed from ISS was hacked with unintended ads.
Russian mission control has indicated that the debris left over from destruction of a Chinese satellite in 2007 poses a “danger” to the International Space Station. Key quote from a Russian official:
“If the calculations show that the debris is approaching the station at an unacceptably close range, the six astronauts will receive the order to take shelter in the two Russian Soyuz spacecraft which are docked with the ISS.”
Astronomers have concluded that the high levels of carbon monoxide that they have detected in the upper layers of Neptune’s atmosphere are the leftover fingerprint of a cometary impact some 200 years ago.
Zephr, a British-built solar-powered unmanned plane was ordered to return to Earth after flying continuously for two weeks without refueling. Key quote:
Zephyr is set to be credited with a new world endurance record (336 hours, 24 minutes) for an unmanned, un-refuelled aircraft – provided a representative of the world air sports federation, who was present at Yuma, is satisfied its rules have been followed properly.
On the subject of caves on the Moon, Paul Spudis has directed me to his very cogent October 2009 post for Air & Space magazine. Here he notes correctly that though lava tube caves on the Moon have value, they are unfortunately apparently not located in the best places for settlement.
Keith Cowing at NasaWatch notes quickly that the current budget battles over NASA have people in NASA concerned about the future of the James Webb Space Telescope. The telescope has further cost overruns, and should NASA end up operating under a continuing resolution rather than a full budget, there won’t be enough money to keep the project above water.
This Slate article not only describes the new symbol India has chosen for its currency, it also gives a nice thumbnail description of the origins of other currency symbols, such as the U.S. dollar sign and the English pound sign.
