A European space probe will attempt its final mission tonight, descending on a comet with little chance of surviving the impact.

The Rosetta space probe was launched in 2004 by the European Space Agency to study a comet about 800 million kilometres from Earth.

The ESA announced the probe was expected to make contact with the comet about 11:20 GMT (7:20pm AWST).

WOW! Check out this amazing play of shadows on #67P, seen from ~11.7km at 05:25UT during #CometLanding https://t.co/axzhWCFMZ9 pic.twitter.com/juYc4nE6yf
