+Jeff Biesiadecki I'm not sure I can agree with you about whether it's nice to see Wopmay again. <shudder> :-)

On March 22, 2010, communication with NASA's Mars rover Spirit was lost.

Originally designed for a 90 Sol mission (a Sol, one Martian day, is slightly longer than one Earth day) few would have expected Mars Exploration Rover Spirit to operate as long as 2210 Sols - that’s 24.5 times the planned mission duration!

“It’s an incredible testimony to engineering that this plucky little craft survived 3 winters, when it wasn’t designed to survive any such weather conditions at all,” said Neil Mottinger, a navigation engineer at NASA’s Jet Propulsion Laboratory.

Landing on the opposite side of Mars from its twin, the still operating Opportunity rover, Spirit was part of an effort to answer important questions surrounding the history of the Martian environment and its suitability for the formation of life. Understandably, one central element of these questions was to better understand the history of water on the planet - from its current status to what early Martian topography may have looked like.

One of many discoveries that Spirit made included finding supportive evidence suggesting rocks from the plains of Gusev had been slightly altered by tiny amounts of water. As the rover had observed, outside coatings and cracks within these samples had suggested water deposited minerals.

While Spirit delivered troves of valuable data home during its activity, it became irrecoverably obstructed in soft soil on Sol 1892 (May 1st, 2009), an incident that would spell the end for the rover. Attempts to free the rover ended on Sol 2155 (January 26, 2010), when NASA reclassified the mission as a stationary research platform. It continued performing science operations from its current location until communication with Spirit was lost on Sol 2210 (March 22, 2010). Attempts to reestablish communication with the rover have been unsuccessful.

Endless applause to all the engineers & operators involved on this unbelievable mission including Mr Maimone, at least for this longevity which has given all those chances to science return. And also let's not forget about Spirit who, through the memories and knowlegdes which the engineers & operators got from Spirit, must have been helping Oppy all through the years.

Happy 11th Birthday Oppy!!

Curiosity scientists will have a new perspective on Mars
NASA and Microsoft have teamed up to develop software called OnSight, a new technology that will enable scientists to work virtually on Mars using wearable technology called Microsoft HoloLens.

Flash!  Read all about it!  Before I forget all about it!  (I was quite relieved to see that we received a Beep from Opportunity, after a couple days of utter silence)
Inevitable age-related issues have surfaced for Mars rover Opportunity and mission engineers are being challenged by an increasingly troubling bout of flash memory glitches.

Newsflash!  New flash!  Engineers have fixed the Opportunity rover's flash memory, restoring its ability to remember whatever it did days ago.  Drive on!

No re-percussions  This weekend's drill tests went well, engineers are narrowing down the cause of the transient short circuit problem and recommending solutions, so Curiosity will be on her way soon.  Who bears short shorts?  We repair short shorts.
JPL engineers think a faulty circuit in the rover's drill bit is responsible for the malfunction that idled the machine last month. It should resume its work soon.

Mars Rover team now investigating a transient short (short short?), you know the drill...
NASA's Curiosity Mars rover is expected to remain stationary for several days for engineering analysis following an onboard fault-protection action on Feb. 27.

Different Strokes.  Curiosity's latest drilling activity used a gentler strategy.
NASA's Curiosity Mars rover is analyzing a rock-powder sample collected by using the rover's drill in a gentler manner than at previous drill targets.

Did the new drilling algorithm necessitate a FSW upload, or was it something that could be controlled in sequencing (e.g., by messing with the parameters)?

Interesting proposal for another fun way to explore Mars

This got me thinking about the possibility of lighter-than-air flight on mars. Obviously with the thin atmosphere the buoyancy gained from a volume hydrogen or helium would be lower than the same volume on earth, but the lower atmospheric pressure might give you the ability to use a vacuum for bouyancy without a heavy pressure vessel...

Opportunity is at Peak performance (even after nearly 11 years on Mars,  without using Flash memory, its arm shoulder joint, or right front steering motor)!  This is the highest elevation reached by a Mars rover yet.
NASA's Mars Exploration Rover Opportunity, continuing to drive while engineers tackle a flash-memory issue, has reached a crater-rim high point on "Cape Tribulation."
