Nasa Messenger's Mercury crash - but with one last pic
FRIDAY 01 MAY 2015
Hurtling to the ground at over 8,700 miles an hour, Nasa's Messenger spacecraft collided with Mercury on Thursday - but had time to send one last picture.

After more than 10 years in space, the Messenger (which stands for
Mercury Surface, Space Environment, Geochemistry and Ranging)
spacecraft, succumbed to Mercury's gravity and crashed to earth - making
a crater estimated to be 16 metres in diameter.

Mercury's very thin atmosphere means the Messenger craft did not slow as
it plummeted to the surface of the planet, resulting in the high speed
and large crater.
The Messenger mission has acquired over 250,000 images as well as other datasets during its 10-year mission.
It entered Mercury's orbit in 2011, and was only expected to survive for
one year. However, earlier this week the craft ran out of propellant
and it was pulled to Mercury's surface.

The Messenger spacecraft is the first ever to orbit Mercury and used
seven scientific instruments to explore the origins of the solar
system's innermost planet.
