What are the rovers up to?

Posted by Emily Lakdawalla on 2009/03/05 02:15 CST

As usual, troubled Spirit's progress sometimes amounts to only centimeters, while golden child Opportunity has already clocked four kilometers on its trek toward Endeavour.

Spirit moved!

Posted by Emily Lakdawalla on 2009/01/07 12:24 CST

Hallelujah! For the first time in almost an Earth year, amateur mars mapper Eduardo Tesheiner is able to scratch a tiny little line on his map of the Mars Exploration Rover Spirit's peregrinations across Gusev Crater.

Five Years of Spirit on Mars

Posted by Emily Lakdawalla on 2009/01/02 10:15 CST

On January 3, 2004, the Mars Exploration Rover Spirit landed on Mars, and I was with the science team at JPL when it happened! I can't believe it's been five years since the successful landing.

Solar conjunction: Holidays for Mars missions, and an Opportunity update

Posted by Emily Lakdawalla on 2008/11/21 01:09 CST

The period of Mars solar conjunction has just begun, which means that a host of scientists and engineers whose day jobs entail interaction with the five active Mars spacecraft are getting a five-week break from the daily grind of operations.

Opportunity's got a long road ahead

Posted by Emily Lakdawalla on 2008/09/19 05:03 CDT

Mars Exploration Rover principal investigator Steve Squyres announced on National Public Radio's Science Friday show the next goal for Opportunity, and it's a long, long, long way away: a huge crater about 12 kilometers southeast of its current location, which the team is referring to internally as "Endeavour."

More things to see in the amazing HiRISE image of Phoenix' descent

Posted by Emily Lakdawalla on 2008/07/10 02:09 CDT

I have posted several times about the amazing photo captured by HiRISE of Phoenix under its parachute as it descended. There have been two common questions I've received about the photo: was there any color data taken, and what more can I tell you about how hard it was to take the photo? I've got answers to both questions for you today.

Some beautiful video from the Spirit and Opportunity landing sites

Posted by Emily Lakdawalla on 2008/05/12 06:02 CDT

A majority of the people who work in planetary geology are usually associated with one or maybe two missions, doing all their research on the results from one instrument on one mission. But there are a few people whose expertise cuts across many space missions, and an even smaller number of people who seem to work on almost everything. Randy Kirk is one of those people.

Shadows cast from Victoria's capes and bays

Posted by Emily Lakdawalla on 2008/04/14 03:51 CDT

This is from the "just plain cool" department: An animation of the shadows of Victoria Crater as seen by the Mars Reconnaissance Orbiter, courtesy of Doug Ellison.

Spirit, seen from space

Posted by Emily Lakdawalla on 2008/03/24 05:46 CDT

The HiRISE instrument on Mars Reconnaissance Orbiter really is a spy camera in space. Check out this sequence of nine images from the HiRISE archives, which Doug Ellison pulled together into an animation covering more than a year of Spirit's mission.

Mars Climate Sounder Collects 20 Millionth Sounding

Posted by Bruce Betts on 2008/03/10 12:00 CDT

Last week Mars Climate Sounder collected its 20 millionth sounding at Mars. Mars Climate Sounder is scanning without problems, collecting science observations of the atmosphere of Mars. Mars Climate Sounder has now been observing Mars for over 17 months (three quarters of a Mars year and also approximately three quarters of the Mars Reconnaissance Orbiter primary science mission).

Have a happy day on Mars

Posted by Emily Lakdawalla on 2008/02/01 11:36 CST

I thought this was a fun image to kick off the weekend. This isn't the first happy-looking crater to be photographed from Mars, but I really like this one; it's more goofy.

Mars Exploration Rovers update: Spirit and Opportunity are both still talking to Earth

Posted by Emily Lakdawalla on 2007/07/23 05:04 CDT

Both Spirit and Opportunity are still suffering under incredibly dark skies, but, amazingly, they are both "power-positive," meaning that they are managing to produce enough power from the limited amount of sunlight to keep the batteries fully charged.

Millions of soundings yield clues to Mars' weather

Posted by Bruce Betts on 2007/04/03 12:00 CDT

Two months after the start of Mars Reconnaissance Orbiter's primary science phase, the Mars Climate Sounder instrument has already acquired more than four million soundings, building toward a vast data set on the three-dimensional structure of Mars' atmosphere over the full Martian year of the orbiter's nominal mission.

A launch delay for Mars Reconnaissance Orbiter

Posted by Emily Lakdawalla on 2005/08/09 12:57 CDT

The Space Shuttle couldn't land at Kennedy Space Center today because of concerns about weather, so I have been expecting a launch delay to be announced for Mars Reconnaissance Orbiter. Indeed, a 24-hour delay has just been announced; the new launch date is Thursday, August 11 from 7:50 to 9:35 a.m. EDT (11:50 to 13:35 UTC).
