A couple of days ago Malin Space Science Systems (MSSS) issued a news notice that explains some of the horse-trading that went on behind the scenes to rescue MARDI, the descent imaging camera that they are building for the Mars Science Laboratory rover.

Planetary System Detected Around SETI@home Target Star

Amir Alexander • November 08, 2007

A fully formed planetary system, with five different planets of varying sizes and orbits has been found, orbiting a star more than 40 light years away. Significantly, it is the very same star, 55 Cancri, that was one of the chief targets of the SETI@home reobservations at Arecibo in March 2003.

Planetary Society's Optical SETI Telescope Offers Online View of Night sky

Bruce Betts • October 30, 2007

The Planetary Society's Optical SETI Telescope was built solely to search for possible light signals from alien civilizations. Located at Oak Ridge Observatory in Harvard, Massachusetts, it is the first dedicated Optical SETI telescope in the world. Its 72-inch primary mirror also makes it larger than any optical telescope in the U.S. east of the Mississippi river.

Professional Pilot Magazine asked me to contribute a prediction about the future of flight for the next century. Naturally, I wrote about solar sailing.

Millions of soundings yield clues to Mars' weather

Bruce Betts • April 03, 2007

Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.

Updates from Past Recipients of the Shoemaker NEO Grants (1 March 2007)

Bruce Betts • March 01, 2007

Thanks to The Planetary Society Shoemaker Grant, the 1.06-meter KLENOT telescope optics was completed at the Klet Observatory. Regular observations of the KLENOT project started in March 2002 under the new IAU/MPC code 246, so we can now present results covering 5 years of this work.

Keeping an Ear to the Center of the Galaxy, Southern SETI Prepares for Great Leap Forward

Amir Alexander • February 26, 2007

Located in the southern part of the continent of South America, Southern SETI has a continuous view of densest star-fields in our galaxy. And, since 1990, it has been sponsored and supported by The Planetary Society.

With Observations in Full Swing, Team Prepares to Remove "Sunglasses" from Telescope

Amir Alexander • February 26, 2007

Winter time is observing time at the Oak Ridge Observatory in Massachusetts, when humidity is low and the sky is often clear. And so it has been for the Optical SETI telescope, which opened its doors in April 2006.
