Mars Exploration Rovers Update: NASA/JPL Team Celebrates Rovers' First Year on Mars as Spirit and Opportunity Return

A.J.S. Rayl • January 05, 2005

As Spirit rang in her new year at Gusev Crater on Mars Monday, NASA officials and mission team members celebrated the Mars Exploration Rovers first anniversary at an event that featured a press conference, storytelling session, and birthday party at the Jet Propulsion Laboratory (JPL).

Mars Exploration Rovers Update: Spirit 'Snaps' Dust-Devils while Opportunity Roves on to Viking (the Crater)

A.J.S. Rayl • March 25, 2005

After more than a year of active-duty research, the Mars Exploration Rovers have caught 'second winds' -- in part because of their new, recently uploaded software and, in part -- however strange it may seem -- from the planet's notorious dust devils.

Mars Exploration Rovers Update: Spirit Investigates New Outcrop Methuselah as Opportunity Roves into a Ripple and Gets Stuck

A.J.S. Rayl • April 28, 2005

The Mars Exploration Rovers have both encountered some truly challenging obstacles in recent days, but have also presented the team with some surprises, and continue to be in overall good health some 16 months after bouncing to a landing, and more than a year after completing their primary missions.

Mars Exploration Rovers Update: Opportunity Roves Out of Sand Dune as Spirit Uncovers Clues of Past Explosions

A.J.S. Rayl • June 05, 2005

Nearly a year and a half after landing on the Red Planet, the Mars Exploration Rovers are continuing to collect important science and impress the team with their resiliency.

Mars Exploration Rovers Update: Spirit Rocks Independence as Opportunity Celebrates With Road Trip

A.J.S. Rayl • June 30, 2005

The Mars Exploration Rovers are still going strong, and both robot field geologists will be working through the July 4th holiday.

Mars Exploration Rovers Update: Spirit Returns (Most of) Panorama from Summit of Husband Hill

A.J.S. Rayl • September 01, 2005

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 Revels in Science at Husband Hill Summit as Opportunity Closes in on Erebus Crater

A.J.S. Rayl • September 22, 2005

Despite a few unexpected bumps and curves in their explorations at Gusev Crater and Meridiani Planum, the Mars Exploration Rovers have been working away and both Spirit and Opportunity have put in a very productive month's worth of work on the Red Planet.

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

A.J.S. Rayl • October 27, 2005

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.

Mars Exploration Rovers Update: Spirit Achieves Martian Year Milestone while Opportunity Reveals Harsh Challenges for Past Martian Life

A.J.S. Rayl • November 30, 2005

In its orbit around the Sun, the Red Planet has been returning to where it was when the Mars Exploration Rovers first landed back in January 2004, and, as the twin robot field geologists are marking the milestone of their first Martian year -- equivalent to almost two Earth years -- fireworks are flashing all around the planet. Although the cause of the fireworks is actually debris from Halley's comet, through which Mars is currently passing, the timing seems so metaphorically appropriate.

Mars Exploration Rovers Update: Spirit Descends Husband Hill as Opportunity Works at a Standstill on Olympia

A.J.S. Rayl • December 30, 2005

The Mars Exploration Rovers have each completed their first Mars Year (687 Earth days) and are close to completing their second Earth year exploring their respective sites on the Red Planet. With both Spirit and Opportunity finding new variations of bedrock in the areas they are exploring, the mission is continuing to send the team holiday gifts in the form of intriguing discoveries.
