The Philae comet lander has fallen silent, according to scientists working on the European Rosetta mission. The fridge-sized spacecraft, which landed on Comet 67P in November, last made contact on 9 July.
When Philae first sent back images of its landing location on Comet 67P, researchers could see it was in a dark ditch. The Sun was obscured by a high wall, limiting the amount of light that could reach the robot's solar panels.
Europe's Philae comet lander has been back in touch with Earth - its first contact since Sunday night (GMT). The communication was relayed by its mothership Rosetta, which is in orbit around the 4km-wide icy dirt-ball known as 67P/Churyumov-Gerasimenko.
The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth. Philae, the first spacecraft to land on a comet, was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
The European Space Agency (Esa) says it will conduct no more dedicated searches for its lost comet lander. The Philae probe made its historic touchdown on the 4km-wide "icy dirtball" 67P in November, but rapidly went silent when its battery ran flat.
When I sat down with the mission's project scientist in California in August 2012, his response was much the same as always: "My best estimate is that it will be in the next couple of years, but it may be in the next couple of days. It's unknown." Not anymore.
The Jupiter Icy Moons Orbiter (Jimo) is part of an ambitious mission to explore the three planet-sized Jovian moons Callisto, Ganymede and Europa. Designing the spacecraft poses a significant engineering challenge given the long distances involved. Controversially, the probe is to be powered by a nuclear propulsion system. Callisto, Ganymede and Europa are thought to harbour oceans of probable water beneath an icy crust. Jimo would be the...
Researchers are testing technology that could allow a lander to melt through the ice crust of Jupiter's moon Europa to reach the water ocean beneath. Space scientists want to send a craft to the Jovian moon because its ocean might, in theory, harbour life. Once through the 10-30km ice sheet, the probe could take a sample of water, to analyse it for microbial life.
