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
Due to funding difficulties within the French space agency, CNES, the Netlander mission has been officially canceled.
The Mars Exploration Rovers are each entering new chapters in their extended missions that are already returning more intriguing discoveries, but they are both beginning to slow down now as the Martian winter closes in on them.
During the last three weeks, the Mars Exploration Rovers have been continuing to rove and explore their respective regions of Mars. Spirit has continued her trek to the Columbia Hills in the Gusev Crater area of Mars, while on the other side of the planet, at Meridiani Planum; Opportunity has been investigating Endurance Crater.
It has been more than a year since the [email protected] crew spent a hectic week at Arecibo, pointing the giant radio telescope at some of SETI's most promising targets. Much of the data collected during the reobservations has since been repackaged as work units, and sent out to users around the world for analysis.
As Spirit continued her journey to the Columbia Hills in Gusev Crater, Opportunity cruised into her extended mission at Meridiani Planum this week, marking the milestone of the rovers' Martian adventure -- full mission success.
This week, the Mars Exploration Rovers team successfully installed the new flight software it was uploading to Spirit and Opportunity last weekend. Now, the rovers have enhanced capabilities that should make their remaining Martian sols even safe and more productive, announced Jan Chodas, flight software manager, at the weekly news briefing at the Jet Propulsion Laboratory (JPL).
2003 was a good year with 50,779 asteroid astrometric observations submitted, including known NEOs and the discovery of a new Aten-class object, 2003 UY12. Based upon the volume of astrometric observations submitted, observatory code 683 was the world's eighth most productive asteroid astrometry station.
As the Mars Exploration Rovers achieved new milestones on the Red Planet this week, NASA approved a plan to extend the missions for both Spirit and Opportunity to mid-September.
The Mars Exploration Rovers continued to crank out scientific findings about Mars this week: Spirit sent home clues of past ground water at Gusev Crater; Opportunity set a one-day distance driving record and returned to the scene of her arrival, the rock she bounced off on upon landing at Meridiani Planum.
The Mars Exploration Rovers each focused their research efforts this week studying the rim of a crater. At Gusev, Spirit continued her study of Bonneville Crater, while at Meridiani Planum Opportunity spent most of her time driving around the southern and eastern portions of Eagle Crater conducting a soil survey of five targets.
After nearly two months of study, Opportunity has emerged from her landing crater at Meridiani Planum and onto
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.
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
Spirit and Opportunity continued their search for evidence of water at Gusev Crater and Meridiani Planum this week, and a lot of excited and smiling faces have been emanating from behind the scenes, in the mission rooms at the Jet Propulsion Laboratory (JPL).
The rovers have been kicking up dirt and roving to new destinations this week, as they pick up the pace and take care of their geological business on Mars.
Mars driving records are falling at Gusev Crater, as the rover Spirit continues its steady progress towards the nearby crater nicknamed
The Mars Exploration Rovers are really starting to 'show their stuff' on the Red Planet. Despite a couple of technological hiccups earlier in the week, the twin robot field geologists are getting down and dirty in the Martian soil.
Both Mars rovers -- Spirit and Opportunity -- are roving on the Red Planet and doing exactly what they were programmed to do as robot field geologists, explore their surrounding areas.
