Busted Russian Mars probe could go to Moon instead:

"Lost Russian probe Phobos-Grunt could give up its trek to Mars and
instead head to the Moon if communication isn't established in the
next few days.

Space agency Roscosmos has given engineers until 21 November to
contact the spacecraft, which is somewhere in orbit around Earth,
because a flight to the Red Planet's moon Phobos will not be possible
after that date.

However, Russian space expert Igor Listov told state news agency RIA
Novosti that if boffins got in touch with the ship after that it would
still have enough fuel to make a trip to Earth's moon instead."
