'Nail-biting' 7 minute descent to Mars - BBC NEWS

'Nail-biting' descent to Mars

Scientists are preparing for "seven minutes of terror" as a Nasa spacecraft makes a nail-biting descent to the surface of Mars.

The Phoenix lander needs to perform a series of challenging manoeuvres along the way as it attempts to land in the planet's polar north.

It then begins a three-month mission to investigate Mars' geological history and potential habitability.
