Mars Exploration Rovers Update: Spirit Homes in on Mitcheltree Ridge, Opportunity Crosses Valley Without Peril

A.J.S. Rayl • March 31, 2007

It's been business as usual on the Red Planet this month as the Mars Exploration Rovers investigated new areas on their ever-moving missions to explore Gusev Crater and Meridiani Planum. Both Spirit and Opportunity chalked up yet another productive month of field geology as they roved onward in their fourth year on location, checking out more of the local environs some 149,597,900 kilometers (93 million miles) away on Earthlings' favored other planet.

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.
