Mars Exploration Rover Mission Status

NASA's Opportunity rover drove about 3.5 meters (11 feet) early Thursday toward a rock outcrop in the wall of a small crater on Mars, and mission controllers plan to send it the rest of the way to the outcrop late Thursday.

Opportunity's twin, Spirit, successfully reformatted its flash memory on Wednesday. Flash is a type of rewritable memory used in many electronic devices, such as digital cameras, to retain information even while power is off. Problems with the flash memory interfered with Spirit's operations from Jan. 22 until this week. Engineers prescribed the reformatting to prevent recurrence of the problem.

On Thursday, Spirit’s main assignment is to brush off an area on the rock nicknamed "Adirondack" to prepare for a dust-free examination of its surface. On Friday, controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., plan to have Spirit grind off a small patch of Adirondack’s outer surface and inspect the rock's interior. Spirit may start driving over the weekend toward a crater about 250 meters (about 270 yards) to the northeast.

For Opportunity, halfway around Mars from Spirit, controllers changed plans Thursday morning. They postponed a trenching operation until the rover gets to an area of its landing-site crater where the soil has a higher concentration of large-grain hematite. That mineral holds high interest because it usually forms under wet conditions. The main science goal for both rovers is to find geological clues about past environmental conditions at the landing sites, especially about whether conditions were ever watery and possibly suitable for sustaining life.

Instead of trenching, Opportunity will be commanded after it next wakes up to drive about 1.5 meters (about 5 feet) farther, possibly to within arm's reach of one of the rocks in the exposed outcrop.

Before it began driving on Wednesday, Opportunity finished using its alpha particle X-ray spectrometer for the first time. This spectrometer, which assesses what chemical elements are present, took readings on an area of soil that the rover had previously examined with its microscope.

Each martian day, or "sol," lasts about 40 minutes longer than an Earth day. Spirit begins its 34rd sol on Mars at 3:22 a.m. Thursday, Pacific Standard Time. Opportunity begins its 14th sol on Mars at 3:43 p.m. Friday, PST. JPL, a division of the California Institute of Technology in Pasadena, manages the Mars Exploration Rover project for NASA's Office of Space Science, Washington, D.C.

When I first saw this image I didn't believe it was real. I still am a little skeptical. No comment eh?

I got word down the grapevine that Sol 33 on Spirit has went according to plan! It's now sunset at Spirit and sunrise at Opportunity!

How long 'til it rains and obliterates those tracks for another bbbillion years. Monsoon season starts around this type, right?

Don't bet on it - this site will be declared a Galactic Historical Monument and a dome will be built over it!

Didn't they once assure us that the sound barrier could never be broken?

Actually no, most scientist knew that it could be, and in fact was broken regularly (ie. the crack of a whip). LIGHT is the real speed limit.

My thoughts too. I noticed it in the air bag tracks early on.

Wasn't one of the biggest news stories last year was when they sent particles FASTER THAN THE SPEED OF LIGHT?

Any comments or ideas on what this may be? Thanks...

My first guess was that it's a gnarly rock, partially buried, with dust blown into hollows in the rock.

However, that little "horn" has a shadow, so it's not buried. I'm still thinking "gnarly rock," though.

It comes from NASA/JPL from Opportunity. It was a panorama shot. I noted there was at least one more object in the image that I found to be dramatic and spectacular. My first thought was that this was ejected from the solar panels opening up, or something from Opportunity or the airbags. It this isn't part of the spacecraft or airbags, It'll be one of the most stunning images to date. IMO.

What I found amazing is that I didn't find anything on the JPL site that referred to this object.

If anyone has the official statement on this, I would appreciate hearing about it.

I tend to disagree with that. What ever it is, I believe it is one of the most significant images yet. I am just a little surprised no official comment on this from JPL. Or maybe there was and I missed it.
