Mars Exploration Rovers Update: Spirit Sleeps through Solstice, Opportunity Cruises Past Viking Record

A.J.S. Rayl • May 31, 2010

The Mars Exploration Rovers made it through their fourth winter solstice in what is the coldest, most challenging Martian winter the twin robot field geologists have experienced.

Is this the eastward turn we've all been waiting for?

Emily Lakdawalla • May 27, 2010

As I discussed on Monday, Opportunity is in the middle of a lengthy trek toward a crater named Endeavour and its tantalizing upraised smectite-bearing rim.

The goal of Opportunity's trek

Opportunity's kilometers-long march across the sands of Meridiani Planum is a great story, and the journey is fun to follow; but what could be worth such a long march?

Opportunity: longest-lived landed Mars mission

Emily Lakdawalla • May 19, 2010

Today is sol 2,246 of Opportunity's mission to Mars; as I write, it's just before 7:00 local solar time. If this sol passes, as her previous 2,245 have done, with Opportunity still alive and speaking to Earth, she will have surpassed a record set on November 12, 1982: Opportunity will pass Viking Lander 1 as the longest-lived landed Mars mission.

Solstice? What solstice?

Emily Lakdawalla • May 14, 2010

Thumbing her nose at this whole winter thing, Opportunity drove 20 meters yesterday, sol 2,240, on the winter solstice.

Happy solstice -- on Mars

Emily Lakdawalla • May 13, 2010

It's the solstice on Mars today: summer in the north, winter in the south.

A Martian Moment in Time, revisited

Emily Lakdawalla • May 12, 2010

A good start to my day today: The New York Times' Lens Blog featured the "Martian Moment in Time" photo that Opportunity took last week in a really nice writeup. I'm so grateful, and still a little surprised, that the folks on the Mars Exploration Rover mission took this idea and ran with it!

A moment in time

Emily Lakdawalla • May 06, 2010

On Mars, at 15:00 local true solar time on May 2, a solitary rover gazed southward across her own dusty deck and snapped three photos, actually three sets of three photos, which were combined to make this view.

Space carnival, rover update, Planetary Radio Live!

Just a linky post today, as I am nanny-less.

Mars Exploration Rovers Update: Spirit Snoozes Past Viking, Opportunity Snaps Endeavour on Horizon

A.J.S. Rayl • April 30, 2010

The Mars Exploration Rovers' fourth Martian winter is proving to be the harshest one yet and Spirit and Opportunity are getting colder than ever before. With temperatures on the Red Planet dropping in April and the Martian winter solstice still two weeks away, the season has turned into a shivering nail-biter.

Spirit: Schrödinger's Rover

Emily Lakdawalla • April 28, 2010

Either Spirit is the longest-lived landed Mars mission ever, or she is not. We won't know for certain unless we manage to observe a radio signal from her.

Sweet dreams, Spirit

Emily Lakdawalla • March 31, 2010

Spirit had been communicating on a once-per-week schedule in recent weeks. During the designated time for the rover to communicate with NASA's Mars Odyssey orbiter passing overhead on March 30, Odyssey heard nothing from the rover.

Mars Exploration Rovers Update: Spirit Begins Hibernation Probably, Opportunity Roves On to Endeavour Crater

A.J.S. Rayl • March 31, 2010

March seems to have come in like a lamb and gone out like a lion on the Red Planet this year as the Mars Exploration Rovers trudged deeper into their fourth winter. While Opportunity finished up work at Concepcin Crater and shifted into gear back on the road to Endeavour Crater, Spirit finished up winter preparations and carried out a limited winter agenda before shifting, it appears, into hibernation mode.

Opportunity's at the twin craters

Emily Lakdawalla • March 27, 2010

Just a little update here to post a Navcam panorama from Opportunity showing that the rover successfully arrived yesterday at the doublet crater she's been aiming for since she left Concepcion a couple of weeks ago.

Opportunity at Concepción from orbit

Emily Lakdawalla • March 24, 2010

I saw this image at the Lunar and Planetary Science Conference so am happy they released it: a view of Opportunity sitting on the north rim of the little, fresh Concepción crater, taken on sol 2153 (February 13, 2010).

LPSC, Day 3: Opportunity, and what the heck is Marquette?

Emily Lakdawalla • March 05, 2010

I wrote earlier about some results from Spirit reported at this year's Lunar and Planetary Science Conference in Houston, Texas; here are the rest of my notes on rover-related talks, from Opportunity's site on the opposite side of Mars.

Gorilla seen in Nasa Snap from Mars? Umm....no.

Emily Lakdawalla • March 03, 2010

Yes, I'm totally not kidding, that is the headline in the Sun: "'Gorilla' seen in Nasa Snap from Mars."

LPSC, Day 1: Spirit and Phoenix

Emily Lakdawalla • March 02, 2010

Where to begin with the Lunar and Planetary Science Conference (LPSC)?

Mars Exploration Rovers Update: Spirit Parks for Winter, Opportunity Tastes Chocolate Hills

A.J.S. Rayl • February 28, 2010

As winter put the freeze on in the southern hemisphere of the Red Planet, the Mars Exploration Rovers slowed down a bit, but continued throughout February to demonstrate the mettle that made them famous: Spirit successfully drove backwards, parked in place for the season, then continued working, as Opportunity roved through rock debris on a cruise around the rim of Concepcin Crater.

Find pics and track the rovers in Google Mars

Emily Lakdawalla • February 11, 2010

I think a goodly proportion of you readers have already figured this out for yourselves since it was launched last March, but I didn't download and install it until last weekend, so this is new to me: Google Mars is awesome.
