Mars Exploration Rovers Update: Spirit Too Finds Traces of Water

Posted by Amir Alexander on 2004/03/05 11:00 CST

Four days after scientists announced that rocks examined by the rover Opportunity in Meridiani Planum were once soaked with water, Opportunity's twin Spirit made some headline news of its own. In a press conference this morning at the Jet Propulsion laboratory in Pasadena, Dr. Ray Arvidson, Deputy Principal Investigator for the rovers, announced that Spirit had discovered the telltale signs that some amount water had once been present in Gusev Crater as well.

Mars Exploration Rovers Update: Opportunity Finds Evidence of Past Liquid Water

Posted by A.J.S. Rayl on 2004/03/03 11:00 CST

The Mars Exploration Rovers have sent home the first real prize of the mission - evidence of past liquid water on the Red Planet. Opportunity -- which landed five weeks ago inside a small crater near exposed bedrock -- has found evidence that Meridiani Planum was once "drenched with water," and, thus, was once suitable for life as we know it, mission scientists announced at a press conference held NASA Headquarters yesterday.

Mars Exploration Rovers Update: Spirit Breaks More Records; Opportunity Digs a Trench

Posted by Amir Alexander on 2004/02/17 11:00 CST

Mars driving records are falling at Gusev Crater, as the rover Spirit continues its steady progress towards the nearby crater nicknamed "Bonneville." On Sol 43, which ended on the morning of Monday, February 16, Spirit drove 19 meters (62.3 feet) in the morning and another 8.5 meters (27.9 feet) in the afternoon. The total drive of 27.5 meters (90.2 feet), breaks the Mars one day drive record of 24.4 meters (80 feet), set by Spirit only 7 sols ago. The previous record holder Sojourner, rover of the 1997 Mars Pathfinder mission, had managed no more than 7 meters (23 feet) in a single sol.

Mars Exploration Rovers Update: A Restored Spirit Studies Adirondack, 'Talks' to Mars Express

Posted by A.J.S. Rayl on 2004/02/08 11:00 CST

A fully restored Spirit got back to work late last week on Gusev Crater, using her rock abrasion tool for the first time to brush, then grind into Adirondack. And before her first day back was done, the rover returned more surprises to the science team in the flow of research data she sent home, and reestablished the "international, interplanetary communication network" by exchanging communiqus with the European Space Agency's orbiter, Mars Express.

Mars Exploration Rovers Update: Spirit Lands on Red Planet, Returns First Images

Posted by A.J.S. Rayl on 2004/01/04 11:00 CST

Spirit -- NASA's first Mars Exploration Rover -- survived the 'six minutes of terror' entering and descending through the atmosphere to land safely -- and upright -- in Gusev Crater on the Red Planet. Just two hours after the confirmation signal of the landing, the first engineering data and images began streaming into the MER Mission Control at the Jet Propulsion Laboratory (JPL), where Spirit and her twin, Opportunity were built.
