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

Posted by Emily Lakdawalla on 2010/05/27 07:24 CDT

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

Posted by Emily Lakdawalla on 2010/05/24 02:00 CDT

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

Posted by Emily Lakdawalla on 2010/05/19 10:26 CDT

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?

Posted by Emily Lakdawalla on 2010/05/14 08:40 CDT

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

A Martian Moment in Time, revisited

Posted by Emily Lakdawalla on 2010/05/12 02:30 CDT

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

Posted by Emily Lakdawalla on 2010/05/06 05:39 CDT

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.

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

Posted by A.J.S. Rayl on 2010/04/30 12:00 CDT

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.

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

Posted by A.J.S. Rayl on 2010/03/31 12:00 CDT

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

Posted by Emily Lakdawalla on 2010/03/27 05:09 CDT

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.

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

Posted by A.J.S. Rayl on 2010/02/28 11:00 CST

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

Posted by Emily Lakdawalla on 2010/02/11 05:28 CST

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.

Pretty picture: Opportunity around Concepcion

Posted by Emily Lakdawalla on 2010/02/09 10:32 CST

Here's a neat picture from Opportunity, a panorama composed of its wide-angle, mast-mounted Navcam cameras, showing the crater Concepcion.

A pretty picture of Concepcion crater

Posted by Emily Lakdawalla on 2010/02/01 10:37 CST

It looks like the rover team thinks Concepcion is pretty enough (in both aesthetic and a scientific senses) to be worthy of the full-color Pancam panorama treatment; color frames started arriving on Earth over the weekend.

Mars Exploration Rovers Update: Rovers Pass 6-Year Milestone as Spirit Halts Extrication to Winter at Troy, Opportunity Cruises to Concepcion Crater

Posted by A.J.S. Rayl on 2010/01/31 11:00 CST

Five and a half years after they were supposed to be history, the Mars Exploration Rovers celebrated their sixth Earth year on the Red Planet with Opportunity pulling up to a fresh, new crater on the road to Endeavour, and Spirit working on repositioning itself to settle in for the coming Martian winter, and perhaps the rest of its mission.

Opportunity's thousand-year-old crater

Posted by Emily Lakdawalla on 2010/01/29 10:59 CST

Since leaving Marquette Island on sol 2,122, Opportunity has been barreling southward on her journey toward Endeavour crater. On her horizon for the last several sols has been a very small but very fresh looking crater named Concepci├│n.

What's up in the solar system in January 2010

Posted by Emily Lakdawalla on 2010/01/04 01:29 CST

While we don't have Moon bases, we do have plenty of spacecraft. Before I get into my more detailed look at the activities of the 20-odd spacecraft wandering about the solar system, I thought I'd look ahead to 2010 more generally and see what the year has in store for us.

Mars Exploration Rovers Update: Spirit Perseveres Struggles, Opportunity Digs in at Marquette Island -- And We Look Back on 2009

Posted by A.J.S. Rayl on 2009/12/31 11:00 CST

The Mars Exploration Rovers quietly wrapped up 2009 this month: Spirit continued to valiantly spin its wheels in an attempt to get out of its embedded location on the west side of Home Plate in Gusev Crater; and Opportunity continued its investigation of Marquette Island, perhaps the oldest Martian rock it's found to date at Meridiani Planum.

Mars Exploration Rovers Update: Spirit Turns Wheels, Opportunity Rests at Rare Martian Rock

Posted by A.J.S. Rayl on 2009/11/30 11:00 CST

The Mars Exploration Rovers managed to make history and uncover history in November and that put both Spirit and Opportunity in the planetary exploration spotlight during the 71st month of an overland expedition that was supposed to be a three-month tour.

Opportunity's poking at Marquette Island; Cassini's catching dancing moons

Posted by Emily Lakdawalla on 2009/11/18 04:58 CST

Since tomorrow's class is going to be on playing with raw images from the rovers and Cassini, I've been playing with recent raw images from the rovers and Cassini! I just thought I'd share a couple of the fun items I've been working with.
