An image showing where the robot probe Philae is due to touch down on a fast-moving comet has been released by the European Space Agency (ESA).
The one square kilometre landing site can be seen close to the top of the image of comet 67P/Churyumov-Gerasimenko above a boulder-filled depression.
Philae's orbiting mother-ship, Rosetta, took the picture with its navigation camera from a distance of 30.5 kilometres (19 miles) on November 6th.
On Wednesday, Rosetta will release Philae at an altitude of 22.5 kilometres (14 miles) from the comet centre at 8.35am UK time. Both the probe and the comet are travelling at about 40,000 mph.
It will take Philae seven hours to reach the surface. A signal confirming a successful landing is expected to arrive on Earth at around 4pm.
Thsee incredible images show the moment the probe dropped from its satellite and first landed on Comet 67P five days ago.
Scientists racing against time to keep the Philae comet lander operating are debating whether to try 'hopping' the probe to a new location.
After the first man-made craft landed on a moving comet we look at the pictures sent back from the daring descent to the historic landing.
