First Planet Discovered in Alpha Centauri System
Information on the Discovery, and also Insights from Debra Fischer
European astronomers have made the first planetary discovery in the closest-to-Earth Alpha Centauri star system. Here is some information about the discovery, and insights from Yale Astronomer Debra Fischer, who leads another Alpha Centauri planet search partially supported by The Planetary Society.

The Shoemaker NEO Grants at 15
The Planetary Society Shoemaker NEO grants celebrate their 15th anniversary of helping to find and track near Earth asteroids. Here's a quick review of the program, and updates on our four multiple-grant winners.
The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics. The telescope, which has been operating the only all-sky optical SETI survey since its opening in 2006, is run by Harvard University Professor Paul Horowitz and his team. The telescope scans the sky every clear night with a 72-inch primary mirror, looking for laser pulses as short as one billionth of a second that could be transmitted by distant extraterrestrials. When observing, it has been able to process 1 terabit (trillion bits) of data every second, that’s as much as in all the books in print every second.

May 16, 2012 is the third martian anniversary of the start of Mars Climate Sounder (MCS) observations from Mars Reconnaissance Orbiter. MCS started measuring the atmosphere of Mars three Mars years ago, on September 24, 2006. We can now compare the weather and behavior of the atmosphere in three different years, and find the temperature differences to be surprisingly large.

Evidence continues to pile up that the Rio Vichada structure in Colombia is indeed the largest impact structure in South America.
Do planets circle our closest stellar neighbors, the system loved by science fiction: Alpha Centauri? We don’t know. But, Debra Fischer, Julien Spronck, and their colleagues at Yale University, in part with Planetary Society support, are trying to find out.
With the latest piece of the puzzle just published in a scientific journal, a solar system mystery that has perplexed people for more than 20 years has been solved, truly thanks to the support of Planetary Society members.

Roscosmos, the Russian Space Agency, has released its official report concerning the failure of the Phobos-Grunt spacecraft, which fell back to Earth from orbit on January 15 after failing to ignite the engines that were to take it to the largest Martian moon.

Phobos-Grunt has returned to Earth, a lot sooner than it should have. Yesterday, at approximately 17:45 UT, the Russian spacecraft and its passengers, including a Chinese orbiter and the Planetary Society's LIFE experiment, descended into Earth's atmosphere.

I'm not looking forward to spending the weekend sitting deathwatch on Phobos-Grunt. It's not science, and it's a sad event, so my instincts would lead me to other subjects. But it contains the Planetary Society's Phobos LIFE experiment.

We explore space for the noblest goals of science and exploration, and we often persevere in spite of challenges. But space exploration is fraught with bad things happening, or, to use the technical term, ouchies. The Planetary Society's Phobos LIFE biomodule will re-enter the Earth's atmosphere in the next few days with the rest of the Phobos-Grunt mission.

After modifying two antennas and attempting to send commands to Phobos-Grunt for weeks without success, ESA has made the decision to stop tracking support.

On Tuesday, November 22 at 20:25 UTC, a European Space Agency ground station in Perth, Australia, successfully made brief radio contact with Phobos-Grunt.

I said I wasn't going to post again unless the spacecraft talked to us, but I changed my mind because finally there were official comments today about the status of the mission from Roskosmos head Vladimir Popovkin.
