Spirit hasn't talked to Earth since March 22 -- so what new information could they have received that would make them pronounce Spirit's possible death? Is there some new analysis of the last bit of telemetry? Some new model indicating Spirit's survival was less likely than previously thought?

With winter still freezing the southern hemisphere of Mars, June might have been an uneventful month for your average working robot, but not the Mars Exploration Rovers (MERs). In fact, from the sounds of silence to a major discovery to an injury scare, the rovers' latest trials, tribulations and achievements, have turned the last four weeks into something of an emotional roller-coaster for some members of the MER team.

Mars Exploration Rover Spirit continued to hibernate this month, parked in place near an old volcanic formation called Home Plate. At the same time though she managed to rove back into the planetary exploration spotlight when a group of the mission scientists announced they had found -- in data from an outcrop the rover visited more than four years ago -- evidence for a past watery environment more suitable for life than any other either Spirit or Opportunity have found, a place where near-pure water existed. 1

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.

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.

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.

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!

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

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 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.

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.

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.

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).

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.
