ISS to dodge space junk
Russian mission controllers have shifted the orbit of ISS about a half mile in order to avoid an unidentified piece of space junk.
Why this election is important
Mark Steyn explains why next week’s midterm election and what the next Congress does has very special significance. Key quote:
In a two-party system, you have to work with what’s available. In America, one party is openly committed to driving the nation off the cliff, and the other party is full of guys content to go along for the ride as long as we shift down to third gear. That’s no longer enough of a choice. If your candidate isn’t committed to fewer government agencies with fewer employees on lower rates of pay, he’s part of the problem. This is the last chance for the GOP to restore its credentials. If it blows it, all bets are off for 2012.
Space tourism ticket prices could drop
Two companies who are offering suborbital tourism space flights have indicated that the price per ticket could drop by 2011.
NASA’s commercial crew program moves forward
The commercial half of NASA’s future manned program is moving foward. The agency today began soliciting bids for “launchers and spacecraft that would transport astronauts to and from low Earth orbit destinations on a commercial basis.” Contract awards are expected by March 2011.
Google Lunar X Prize
The private race to the Moon, led by the Google Lunar X Prize. Key quote:
The Google Lunar X PRIZE offers a total of $30 million in prize money to the first privately funded teams to land robots on the Moon that explore the lunar surface by moving at least 500 meters and by sending back two packages of high definition video and photos we call Mooncasts. Unlike our first competition, the $10 million Ansari X PRIZE, the Google Lunar X PRIZE isn’t a ‘winner take all’ proposition: instead, we have a $20 million Grand Prize, a Second Place Prize that will award $5 million to the second team to meet all of the requirements, a series of technical bonus missions that can allow teams to earn as much as an additional $4 million, and a $1 million award that will go to teams that make the greatest contribution to stimulating diversity in space exploration and, more generally, in science, technology, engineering, and mathematics.
The competition operates on a “payment on delivery” model: the prize money is only given to teams after they complete a successful mission, meaning that each team needs to raise all the capital needed to design, develop and conduct their missions on their own. We’re now three years into a fairly long effort: the prize is available until all of the prize purses are claimed or until the end of the year 2015. Last week, we accepted our 24th team into the competition.
Last flight for Discovery set for Monday
The leak on the space shuttle Discovery appears fixed, and NASA managers have confirmed the launch date as Monday, November 1, 4:40 pm (Eastern). This will be Discovery’s last flight.
The once and future Moon
Paul Spudis provides a very detailed analysis of the recently released LCROSS lunar results. Key quote:
The Near-IR spectrometers on the LCROSS shepherding satellite detected abundant water (H2O) but also hydrogen sulfide (H2S), ammonia (NH3), methanol (CH3OH), methane (CH4), ethylene (C2H4) and sulfur dioxide (SO2). The uv-vis spectrometer found carbon dioxide (CO2), sodium, silver, and cyanide (CN). Aboard the distant LRO spacecraft, the ultraviolet LAMP imager detected hydrogen (H2), nitrogen, carbon monoxide (CO), sodium, mercury, zinc, gold (!), and calcium. But water, present in quantities between 5 and 10 weight percent, is the most abundant volatile substance present.
Wikipedia bans global warming propagandist
Wikipedia bans global warming propagandist. Key quote:
Through his position, Connolley for years kept dissenting views on global warming out of Wikipedia, allowing only those that promoted the view that global warming represented a threat to mankind. As a result, Wikipedia became a leading source of global warming propaganda, with Connolley its chief propagandist. His career as a global warming propagandist has now been stopped, following a unanimous verdict that came down today through an arbitration proceeding conducted by Wikipedia.
