First photos from comet lander Philae – gallery

The spacecraft that made an historic descent to a comet is resting at an angle in the shadow of a crater wall – and sending pictures back to earth. But it seems to be half a mile from its target…

One of its legs appears to be suspended in space while the other two have made contact with the ground.

Scientists are frantically trying to establish precisely where the probe ended up on comet 67P/Churyumov-Gerasimenko, a 2.5 mile rugged lump of ice and dust more than 300 million miles from Earth.

As the news emerged today it became clear how narrowly the landing mission averted disaster.

Images released today by the European Space Agency show the movement of the craft:

After being released from its Rosetta mothership, Philae descended as planned to a relatively flat area on the smaller of one of the comet’s two lobes.

But two harpoons that were supposed to anchor the craft to the surface failed to deploy and the probe bounced a kilometre (0.6 miles) into space, remaining suspended above the comet for nearly two hours.

Drawn by the comet’s ultra-low gravity, it slowly fell again and bounced a second time before finally coming to rest – apparently to one side of a large crater.

The craft is partly in the shadow of a cliff-like wall, which could seriously hamper its ability to generate electricity from its solar panels.

By using one of Philae’s instruments to transmit radio signals through the comet, scientists were able to obtain a rough idea of its location.

They believe it to be about a kilometre away from the original landing site.
