Mars Exploration Rovers Update: As Mars Orbits Nearer to Earth, Spirit and Opportunity Rove Onward into New Territories

Posted by A.J.S. Rayl on 2005/10/27 12:00 CDT

The Mars Exploration Rovers science team witnessed a bit of an expansion down here on Earth this month, while up on the Red Planet Spirit and Opportunity continued roving along. As Halloween nears, the twin robot geologists have put in another solid month's worth of work, overcoming every occasional "hiccup." At this point, as Mars' orbit brings it as close to Earth as it will get until the summer of 2018, both Spirit and Opportunity are moving into new territories at their respective inspection sites.

A piece of a new picture from Hayabusa

Posted by Emily Lakdawalla on 2005/10/04 06:21 CDT

The Hayabusa mission has proven to be a bit of a tease -- they were releasing lots of images to the public as they approached asteroid Itokawa, but once they arrived, the image releases shut down entirely.
