We explore space for the noblest goals of science and exploration, and we often persevere in spite of challenges. But space exploration is fraught with bad things happening, or, to use the technical term, ouchies. The Planetary Society's Phobos LIFE biomodule will re-enter the Earth's atmosphere in the next few days with the rest of the Phobos-Grunt mission.

I'm not looking forward to spending the weekend sitting deathwatch on Phobos-Grunt. It's not science, and it's a sad event, so my instincts would lead me to other subjects. But it contains the Planetary Society's Phobos LIFE experiment.

It's the best of times for Mars exploration because we've got three orbiters and a rover studying the Red Planet. It's also the worst of times for my Russian, European, and Chinese colleagues who were part of the Phobos-Grunt mission.

As New Year's Eve moved from time zone to time zone across planet Earth, the Mars Exploration Rover (MER) team looked to 2012 and wrapping its eighth Earth year of exploring, while up on the Red Planet Opportunity settled into the

With a new rover, Curiosity, on its way to Mars, Jason Davis takes a look at what we knew - or thought we knew - about the planet back in 1935.

After modifying two antennas and attempting to send commands to Phobos-Grunt for weeks without success, ESA has made the decision to stop tracking support.

A few fortunate (and forward-thinking) skywatchers looked upward in the hours after Curiosity's launch and were able to see the spacecraft leaving Earth.

It was a textbook launch for the Atlas V 541 today at 15:02 UTC, and within an hour after liftoff, the Centaur second stage had sent Curiosity on its way for an 8.5-month journey to Mars.

On Tuesday, November 22 at 20:25 UTC, a European Space Agency ground station in Perth, Australia, successfully made brief radio contact with Phobos-Grunt.

As I was beginning my research for my two magazine articles on the Curiosity rover's upcoming mission to Mars, I needed to figure out for myself how exactly this gigantic, ungainly machine fit in to the context of past Martian missions.

I said I wasn't going to post again unless the spacecraft talked to us, but I changed my mind because finally there were official comments today about the status of the mission from Roskosmos head Vladimir Popovkin.

I repeatedly rewrote yesterday's post on the problem suffered by Phobos-Grunt after its apparently perfect Zenit launch and thought it was time to begin fresh.
