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.

Posted by A.J.S. Rayl on 2005/09/01 12:00 CDT

Spirit has returned enough pictures from the summit [summit #1] of Husband Hill for the Mars Exploration Team to have put together a 240-degree color panorama of her view, which they released at a news conference today, held at NASA headquarters in Washington D.C. In coming days, the rover will return the rest of the images to complete the full, 360-degree, color panorama.

Mars Exploration Rovers Update: Spirit and Opportunity Celebrate Christmas by Working

Posted by A.J.S. Rayl on 2004/12/21 11:00 CST

The Mars Exploration Rovers are trudging ever onward through the dead of winter on the Red Planet dreaming, perhaps, if robots dream, of a white Christmas. But Spirit and Opportunity are robots after all and come this weekend "the poor little rovers will have to keep working, even on Christmas," MER Project Scientist Joy Crisp, of the Jet Propulsion Laboratory (JPL), told The Planetary Society earlier today.

Mars Exploration Rovers Update: Rovers Go Up Hills, Down a Crater, and May be Showing Signs of Age

Posted by A.J.S. Rayl on 2004/06/15 12:00 CDT

The twin rovers Spirit and Opportunity continue their trek across the varied surface of the Red Planet, climbing hills and descending into a crater. After a two-month journey of over 3 kilometers through rocky terrain, Spirit has now begun climbing the Columbia Hills, which were seen on the horizon in the early panoramas taken from the landing site. The rover is expected to spend much of its remaining life climbing the hills and analyzing their geological make-up. Meanwhile, on the other side of the planet, Opportunity is carefully descending into the stadium-sized depression dubbed "Endurance Crater" by the MER team. The rocky formations revealed on the slopes of the crater promise to provide some of the richest sources for studying the geological history of Mars.
