SEE IT NOW: The Planetary Society's CEO, Bill Nye the Science Guy, joined Director of Projects Bruce Betts for a live webcast as 2012 DA14, a 45-meter asteroid, was passing Earth. Bill and Bruce also marveled at video of the meteor burst high over a city in Russia.

David Warmflash, who organized a science (and peace) experiment with the Planetary Society for the ill fated STS-107 Columbia mission, reflects on that tragic day ten years ago.
Using a Planetary Society provided camera, Gary Hug in Kansas, USA discovered Potentially Hazardous Asteroid 2013 AS27 on Jan. 7, 2013. Shoemaker winner Bob Holmes provided the first follow up observations of this 140m-310m wide asteroid.
Calling (Really Serious) Asteroid Hunters
New Shoemaker NEO Grant Call for Proposals
I am happy to announce a new call for proposals for The Planetary Society’s Gene Shoemaker Near Earth Object (NEO) grant program, which is celebrating its 15th Anniversary. Proposals are due Feb. 4, 2013.
PlanetVac: Sucking Up Planetary Regolith
A New Planetary Society Project
Learn about the Planetary Society’s newest project: PlanetVac, with Honeybee Robotics, aims to prototype and test in a huge vacuum chamber a new way to sample planetary surfaces that could be used for sample return or for in situ instruments.
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.
Chris Biddy from Stellar Exploration Inc. presented information about our LightSail project at the 2012 Aerospace Mechanisms Symposium
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.

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.

A daily cycle of cloud formation in the Martian tropics during northern summer is driven largely by solar radiation and the associated solar thermal tide. Models predict a striking pattern of cloud formation above the high altitude volcanoes of the Tharsis region. At mid-day, the atmosphere is typically free of clouds due to elevated temperatures. Beginning in the early evening hours, atmospheric cooling at altitudes above 20 kilometers begins to foster water ice cloud formation. During the night, the altitude of cloud formation descends closer to the surface.
