Posted by Emily Lakdawalla on 2014/02/27 10:16 CST | 3 comments

Phoenix is dead...long live Phoenix!

Posted by Emily LakdawallaBruce Betts on 2010/06/02 03:11 CDT

The latest HiRISE images of the Phoenix polar lander, taken near Mars' northern summer solstice, show why we haven't heard from the spacecraft since it fell silent on November 2, 2008: it appears the solar panels have collapsed.

No, they can't push with the arm to free Spirit

Posted by Emily Lakdawalla on 2009/12/15 11:25 CST

I've gotten this question about once a week since Spirit got stuck, but yesterday, two different readers asked the same question within an hour of each other, so I figured it was time for a blog entry.

Danes on Mars

Posted by Emily Lakdawalla on 2008/07/17 08:41 CDT

I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as "that Danish magnet guy," the fellow responsible for the magnet experiments on nearly every American Mars mission. The magnets were originally designed to study the properties of airborne Martian dust, which would help determine its composition.

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.

Yep, it's ice!

Posted by Emily Lakdawalla on 2008/06/20 04:43 CDT

The Phoenix mission confirmed it this morning: the disappearing act pulled by those chunks of bright material in the Dodo trench pretty much nails the identification of the bright material as ice, which is great news for the mission. Ice is what Phoenix went all the way to Mars to study; it's what the team has been aiming for all these years.
