The two piggyback microprobes aboard NASA's Mars Polar Lander (MPL) have been named Amundsen and Scott after the famous first South Pole explorers early this century. The microprobes, flying the second Deep Space mission in NASA's new Millennium programme, will smash into an area close to the Martian south pole at about 640km/h (400mph) on 3 December, after being ejected from the MPL as it attempts to make its soft landing on the borders of the pole.
