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.
I received the following question by email last week: "Do you know if the Mars rovers team has any plans to photograph Venus and Earth together in the evening sky from either rover site? They will be closest together around Sept. 29th."
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.
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
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.
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.
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).
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.
The Mars Exploration Rovers are roving ever on into new territories and deeper into the history books as they close in on the end of one full Earth year of active duty at their respective sites on Red Planet.
As winter gives way to spring on the Red Planet, the Mars Explorations Rovers are maintaining their 5-day a week work schedules and continuing to send surprises home to Earth. Despite a recurring 'ache' in one of her steering motors, Spirit is continuing her climb in the Columbia Hills toward a rock called Uchben, while her twin, Opportunity, is completing her work at Wopmay.
After nearly two weeks of sparse, infrequent communication, Spirit and Opportunity have survived winter solstice and resumed "reliable" contact with Earth and the Mars Exploration Rover team -- and NASA has extended funding for an additional six months of operations, as long as the little robot geologists keep working, space agency officials announced late Tuesday.
During the last four weeks, the Mars Exploration Rovers have braved the Martian winter to continue their geologic field work, sending home more evidence of past liquid water on the Red Planet and images of bizarre geologic formations the likes of which no one has seen before.
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.
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.
