Big hunks of carbonate rock on Mars at last

Emily Lakdawalla • June 10, 2010

Carbonate rocks should be all over Mars. But it's been hard to find carbonates—surprisingly so.

Mars Exploration Rovers Update: Spirit Sleeps through Solstice, Opportunity Cruises Past Viking Record

A.J.S. Rayl • May 31, 2010

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.

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

Emily Lakdawalla • May 27, 2010

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

Emily Lakdawalla • May 24, 2010

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

Emily Lakdawalla • May 19, 2010

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.

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

It's the solstice on Mars today: summer in the north, winter in the south.

A Martian Moment in Time, revisited

Emily Lakdawalla • May 12, 2010

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

Emily Lakdawalla • May 06, 2010

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.

Space carnival, rover update, Planetary Radio Live!

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