A veteran skywatcher has captured a video of the doomed Russian Martian space probe Phobos-Grunt that provides evidence of why ground control has only sporadically been able to contact it.

"The images show that the Phobos-Grunt is moving backwards, with the solar panels deployed but not lightened by the Sun," French astrophotogapher Thierry Legault writes [1] on his website.

No sunlight on the panels, no electricity to the probe; no electricity to the proble, no communication with the ground, it appears.

Legault's remarkable video [2] (scroll down), clearly shows Phobos-Grunt in reverse, with the solar panels deployed, but in darkness.

According to Legault, the probe shows no signs of tumbling, his evidence being a video he took a day before the one he provides on his website, which shows Phobos-Grunt in a similar orientation.

After a successful launch [3] and orbital insertion on November 9 of last year, Phobos-Grunt failed to fire the engines [4] that were to take it to the Red Planet. Now, Larault writes, "Phobos-Grunt is out of control and its atmospheric reentry is currently scheduled for mid-January," a reference to reports that the failed Mars mission should rain hot chunks of itself onto terra firma [5] on or around January 15. ®

Legault's astrophotography has captured a number of exceptional images, including solar transits of the space shuttle Atlantis and Hubble Space Telescope [6] in May 2009 and Atlantis and the ISS [7] in May 2010. The Reg recommends that all devotees of space exploration take a moment to examine his online gallery [8].
