New Developments on the Road to Cosmos 2

Louis D. Friedman • June 23, 2008

The Planetary Society and Cosmos Studios remain committed to flying the first flight with light. Our spacecraft, Cosmos 2, is a maneuverable solar sail that may be the precursor to a new mode of interplanetary travel, and could one day take us to the stars.

Mars Climate Sounder Collects 20 Millionth Sounding

Bruce Betts • March 10, 2008

Last week Mars Climate Sounder collected its 20 millionth sounding at Mars. Mars Climate Sounder is scanning without problems, collecting science observations of the atmosphere of Mars. Mars Climate Sounder has now been observing Mars for over 17 months (three quarters of a Mars year and also approximately three quarters of the Mars Reconnaissance Orbiter primary science mission).

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 [email protected] 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 [email protected] 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.

Making Light Work

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

Bruce Betts • March 01, 2007

Update as of March 4, 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.

Update: Monitoring the Weather?

Louis D. Friedman • October 20, 2006

The bigger the dream, the harder it is to achieve it. Our dream at The Planetary Society is to fly the first solar sail mission -- and prove the technology that might someday take humanity to the stars.

With Multi-Beam Receiver, [email protected] Takes Giant Step Forward

Amir Alexander • August 14, 2006

In seven intense days spent at the radio telescope Chief scientist Dan Werthimer and his colleagues completely overhauled the way SETI data is gathered at Arecibo, and ensured that [email protected] will henceforth enjoy the benefits of gathering data with the most advanced equipment anywhere in the world.
