Russian space agency Roscosmos says 200kg fragments may survive re-entry but expects toxic fuel to vaporise

A Russian spacecraft that became stranded in orbit on the way to Mars last year is expected to fall back to Earth next week.

The 13.5 tonne Phobos-Grunt has been circling Earth since November when rocket boosters failed to ignite and send the spaceship on its journey to the Martian moon of Phobos. The spacecraft suffered a computer malfunction after launch and when repeated attempts to contact the rocket failed, the Russian space agency, Roscosmos, had to abandon the mission.

Officials at Roscosmos admitted that 20 to 30 fragments of Phobos-Grunt, weighing a total of 200kg, might hit the Earth. Among the most likely parts to survive are the cone-shaped sample return capsule that is protected with a heat shield. The capsule was designed to survive a crash landing without a parachute.
