Russia's Mars-bound probe Phobos-Grunt had an almost immediate
engine failure after launch, and now the race is on for the
space agency to correct its course and get it back on track toward the red planet.
The craft successfully launched from the Baikonur cosmodrome in
Kazakhstan on 9 November (Moscow time), and separated from its
Zenit-2 booster rocket some 11 minutes later. But its engines
failed to kick in, and it's now trapped in Earth's orbit.
The Russian space agency says that it now has three days to
correct the probe's fault remotely, turn on its engines and break
out of Earth's orbit, before the $167 million craft's batteries run
dry.
The probe's plan was to journey to
Mars, circle the planet for a few months, and then touch down on
the Martian moon of Phobos. Once there, the robotic spacecraft
would scoop up a couple hundred grams of soil and return the
scientific payload to Earth in 2014.
Phobos-Grunt ("grunt" means "ground" or "soil" in Russian) is
also carrying China's Yinghuo-1 satellite, which is hitchhiking
towards Mars. Plus, The Planetary Society has sent a package of
micro-organisms to test how extremeophiles like
Tardigrades could survive in the pressures of space.
The mission was supposed to be the heroic comeback for Russia,
after two decades of failed missions to Mars.
1988's Phobos 1
lost its way en-route to Mars after a faulty command sequence sent
from Earth caused the spacecraft to shut down. Phobos 2
triumphantly reached the red planet and even managed to return 38 images, but
contact was lost before it could touch down on the Martian
moon.
Russia tried again in 1996 with Mars 96, but it crashed into the
ocean shortly after lift-off. Phobos-Grunt, the fourth Mars-bound
craft, had issues even before lift off. It was supposed to blast
off in October 2009, but the launch was delayed for two years
because the craft wasn't ready.
If Russia manages to save Phobos-Grunt in time and get it back
on track, it will reach Mars in September 2012 and land on Phobos
in February 2013.
