Yes  very good report.
The Pheonix mission may be over due to freezing temps and dust on the solar collectors . That was a fixed platform lander that was looking for and found water on Mars

It's amazing how lucky they were to get that gust of wind...

The Rovers yes.
Pheonix was not so lucky NASA declared it dead today :(

There are 2, right? Spirit and Opportunity.

What's up with Phoenix?

Phoenix went dead because it's not getting enough power from the sun. That's the problem with having a solar powered probe in a planet's polar region.

BTW, Phoenix confirmed the existence of ice on Mars. It's existence was suspected prior to the landing.

Speaking of water on Mars:

Quote
Mars has vast glaciers hidden under aprons of rocky debris near mid-latitude mountains, a new study confirms, pointing to a new and large potential reservoir of life-supporting water on the planet.  


These mounds of ice exist at much lower latitudes than any ice previously found on the red planet.


"Altogether, these glaciers almost certainly represent the largest reservoir of water ice on Mars that's not in the polar caps," said John Holt of the University of Texas at Austin and the main author of the study. "Just one of the features we examined is three times larger than the city of Los Angeles and up to one-half-mile thick, and there are many more."


The gently sloping mid-latitude debris flows have puzzled scientists since they were revealed by NASA's Viking orbiters in the 1970s ¿ they looked very different than the fans and cones of debris found near mountains and cliffs in Mars' equatorial regions.


Since their discovery, scientists have been debating how the features formed, with some proposing they were debris flows lubricated by ice that had since evaporated away. But more recent observations suggested that the features "might be more ice than rock," Holt said. In other words, they could be Martian glaciers.


Holt and his colleagues used radar observations of the features, taken by NASA's Mars Reconnaissance Orbiter (MRO), to peer into the features. The findings, detailed in the Nov. 21 issue of the journal Science, suggest that the glacier theory is correct.


Finding huge deposits of ice at the Martian mid-latitudes is a boon to both the study of past potential Martian habitability, as well as future human exploration. Glaciers are huge reservoirs of water once they melt, key to all life as we know it.


Radar echoes


The team used MRO's Shallow Radar instrument to penetrate the rocky debris flows that lie in the Hellas Basin region of Mars' southern hemisphere. They examined the radar echoes to see what lay beneath the surface. All signs pointed to ice, and lots of it.


The radar echoes received back by MRO indicated that radio waves passed through the overlying debris material and reflected off a deeper surface below without losing much strength ¿ the expected signal for thick ice covered by a thin layer of debris.


The radar echoes also showed no signs of significant rock debris within the glaciers, suggesting that they are relatively pure water ice.


"These results are the smoking gun pointing to the presence of large amounts of water ice at these latitudes," said Ali Safaeinili, a Shallow Rader team member at NASA's Jet Propulsion Laboratory in Pasadena, Calif.


How old?


The sheer amount of ice present in the flows studied was surprising; extrapolating from the Hellas Basin feature to the many others present in both Martian hemispheres, there seems to be a lot of ice hiding under the Martian surface.


The researchers estimate that the amount of ice in these mid-latitude glaciers is about 1 percent of the ice that's in Mars' polar caps ¿ roughly equivalent to the ratio of Earth's non-polar glaciers to its polar ice, Holt told SPACE.com. The glaciers could hold as much as 10 percent of the ice in the polar caps, similar to comparing Greenland's ice sheets to Antarctica, Holt added.


But just how the ice got there is still a mystery.


"You shouldn't have ice of this quantity at these latitudes," Holt said.


The theory is that the ice formed when Mars' orbital tilt was much different than it is now (the axis the planet spins on has considerable "wobble," meaning its angle changes over time) and the planet was much colder, allowing ice to form on the surface.

Ice on the surface of Mars today would immediately sublimate (or change directly into the gas phase). The rocky debris covering the ice is likely what keeps it in place today and has allowed it to survive below the surface for millions of years.

Scientists aren't exactly sure during which glacial ice in Antarctica preserves the record of traces of ancient organisms and past climate history."

Ancient ice layers in glaciers on Earth preserve the signature of the current atmosphere at the time that they formed. Head thinks the same could be true of the Martian glaciers. In particular, small bubbles that form as the ice layers are deposited could have "samples of the atmosphere at that time," he said.

A lander capable of drilling down several meters could be able to sample the ice in the glaciers.

"These are quite accessible to landers," Holt said.

They could also be a source of water for any future manned Mars expeditions. (When the researchers travel to Antarctica, for instance, they simply knock off chunks of ice and melt them instead of lugging water with them.)

"It's a lot of ice," Holt said. "You could support a base for a long time."

OPPORTUNITY UPDATE:  Good Health Report After Hiatus in Communications - sols 2500-2511, Febebruary 04-15, 2011:


Opportunity emerged from the solar conjunction in good order. Solar conjunction is the period when communications between Earth and Mars are disrupted because the Sun is directly in between the two planets.


Telemetry has been returned from the two-week solar conjunction period. With the known exception of the miniature thermal emission spectrometer (Mini-TES), all systems are healthy. Extensive mössbauer (MB) integration spectra were successfully collected from the surface target Luis de Torres.


The rover has resumed normal tactical operations. The plan ahead is to perform a rock abrasion tool (RAT) grind on the surface target Luis de Torres for follow-on microscopic imager (MI) mosaics and alpha particle X-ray spectrometer (APXS) measurements.


Completing that, Opportunity will resume the trek towards Endeavour crater. As of Sol 2511 (Feb. 15, 2011), solar array energy production was 505 watt-hours with an elevated atmospheric opacity (Tau) of 0.949 and a solar array dust factor of 0.597.


Total odometry is 26,658.64 meters (26.66 kilometers, or 16.56 miles).


Wow 17 miles of surface and it is still performing most of it's functions.


I am really impressed with these small robots

OPPORTUNITY UPDATE:  Study of 'Ruiz Garcia' Rock Completed - sols 2527-2532, March 04-09, 2011:


Opportunity completed the in-situ (contact) investigation on the surface target Ruiz Garcia at Santa Maria crater.


On Sol 2520 (Feb. 25, 2011), the rover used the robotic arm (Instrument Deployment Device, or IDD) to collect a microscopic imager (MI) image mosaic of Ruiz Garcia. Then, it placed the alpha particle X-ray spectrometer (APXS) down on the target for multi-sol integration. On Sol 2531 (March 8, 2011), the rover backed away from the target and drove about 8.7 meters (29 feet) north to set up for the final wide-baseline stereo imaging, the last imaging before leaving Santa Maria crater.


As of Sol 2532 (March 9, 2011), solar array energy production was 412 watt-hours with an elevated atmospheric opacity (Tau) of 1.05 and a solar array dust factor of 0.5565.


Total odometry is 26,695.66 meters (26.70 kilometers, or 16.59 miles).

OPPORTUNITY UPDATE:  Opportunity Back on Path to 'Endeavour' - sols 2540-2545, March 17-22, 2011:


Opportunity completed the final position for the last wide-baseline stereo imaging of "Santa Maria" crater.


On Sol 2542 (March 19, 2011), the rover moved toward the final "eye" of the wide-baseline imaging location with a drive of 8.3 meters (27 feet). Over the next several sols, the rover collected extensive panoramic camera (Pancam) images of the crater and its interior for the wide-baseline imaging campaign.


With her work now complete at Santa Maria, Opportunity has resumed her trek to Endeavour crater, still some 6.5 kilometers (4 miles) away. For the next sol's plan, a drive of approximately 100 meters (328 feet) due east was sequenced, leaving Santa Maria in the rover's rear view mirror.


As of Sol 2545 (March 22, 2011), solar array energy production was 453 watt-hours with an elevated atmospheric opacity (Tau) of 0.986 and a solar array dust factor of 0.588.


Total odometry is 26,709.42 meters (26.71 kilometers, or 16.60 miles).

SPIRIT UPDATE:  Spirit Remains Silent at Troy - sols 2567-2573, March 24-30, 2011:


No communication has been received from Spirit since Sol 2210 (March 22, 2010).


Deep Space Network X-band listening and recovery commanding continue. The project has been systematically conducting commanding over a range of frequencies and over a range of local solar times on Mars. This covers the possibility that the rover's receiver has degraded and/or the clock has drifted significantly since March of 2010.


The project is continuing the commanding of extra-long ultra-high frequency (UHF) relay passes to account for possible rover clock drift or clock error and to make the rover responsive to UHF relay (if it is has experienced a mission-clock fault). The team is also commanding the backup solid-state power amplifier, in case the primary X-band transmitter has failed.


Total odometry is unchanged at 7,730.50 meters (4.80 miles).

OPPORTUNITY UPDATE:  Opportunity Completes Several Drives This Week - sols 2546-2553, March 23-30, 2011:


Opportunity has resumed the trek towards Endeavour crater with a series of drives.


On Sol 2547 (March 24, 2011), the rover drove over 100 meters (328 feet) due east away from Santa Maria crater and toward Endeavour. On the next sol, Opportunity completed another long drive of over 114 meters (374 feet), but this time to the south to avoid some boulder-strewn terrain. On Sol 2551 (March 28, 2011), the rover continued in a south-southeast direction with a 71-meter (233 foot) drive to avoid more difficult terrain. Opportunity drove again on Sol 2552 (March 29, 2011), with a 39-meter (128-foot) drive, crossing another odometry mark. Opportunity has now driven over 27 kilometers (almost 17 miles) on Mars!


There has been a small increase in the motor currents for the right-front wheel. The project is keeping a close eye on this. A diagnostic of the miniature thermal emission spectrometer (Mini-TES) instrument was performed on Sol 2550 (March 27, 2011). The result of these tests still indicates anomalous behavior. More testing is planned. As of Sol 2552 (March 29, 2011), solar array energy production was 423 watt-hours with an elevated atmospheric opacity (Tau) of 0.914 and a solar array dust factor of 0.560.


Total odometry is 27,035.63 meters (27 kilometers, or 16.80 miles).
