Asteroid impact threat
End of the world alert! Scientists have identified an almost half mile wide asteroid with a 1 in 1000 chance of hitting the Earth in 2182.
Very brief descriptions, with appropriate links, of current or recent news items.
End of the world alert! Scientists have identified an almost half mile wide asteroid with a 1 in 1000 chance of hitting the Earth in 2182.
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.
Using Google Earth, a curator at an Italian museum has discovered a previously unknown, very young, and almost pristine impact crater hidden in the deserts of Egypt.
This Orlando Sentinel analysis of the various Congressional NASA budget proposals working their way through the House and Senate right now concludes, as I have been saying for months, that the future for NASA is not good. Key quote:
The plan orders NASA to build a heavy-lift rocket and capsule capable of reaching the International Space Station by 2016. But it budgets less money for the new spacecraft β about $11 billion during three years, with $3 billion next year β than what the troubled Constellation program would have received. That β plus the short deadline β has set off alarms.
A star with an appetite: Astronomers have used the Chandra X-Ray Observatory to take a closer look at an engimatic star in the constellation Pisces and found that the dust cloud that surrounds it as well as the unusual and enormous jets that shoot from it probably originated when the star evolved, expanded, and swallowed an orbiting companion, either a giant planet or companion star.
Tucker Carlson, the editor-in-chief of the Daily Caller, has written a lengthy essay on his organization’s series on the scandal surrounding the defunct liberbal Journolist listserv. Key quote:
Weβre not contesting the right of anyone, journalist or not, to have political opinions. (I, for one, have made a pretty good living expressing mine.) What we object to is partisanship, which is by its nature dishonest, a species of intellectual corruption. Again and again, we discovered members of Journolist working to coordinate talking points on behalf of Democratic politicians, principally Barack Obama. That is not journalism, and those who engage in it are not journalists. They should stop pretending to be. The news organizations they work for should stop pretending, too.
Read it all.
The space war continues. The House Committee of Science and Technology has amended its budget proposal to include an extra shuttle flight, making its proposal match the Senate’s proposal in at least this one way.
The Russians unveiled today a new proposed replacement for their Soyuz capsule, capable of carrying six astronauts into orbit. Interestingly, the design does not use parachutes to land, but solid rocket engines.
