1m/s is about 2.3mph. I don't know what the landing velocity was though.

Philae was released at 22km and fell to the surface in 7 hours, so average about 3km h-1, probably about 6kmh-1 at touchdown (figures from memory and therefore not reliable but in the right ballpark)

On BBC radio 4 later today at 21:00.

The Rosetta Mission

Frontiers

The European Space Agency's Rosetta mission to 67P/Comet Churyumov-Gerasimenko reaches its most dramatic moment on 12th November. BBC News correspondent Jonathan Amos will cover the event for a special edition of Radio 4's 'Frontiers' programme.

The real error in landing location was much smaller than expected, says Paolo Ferri. It was expected to be a circle around half a kilometre wide.

It may be that Philae has settled down in a slightly different landing place. We will know more tomorrow, says Ulamec.

There is currently no data link between Philae and Rosetta because Rosetta is on the other side of the comet, but that was expected.

"Maybe today we didn't just land once, we landed twice," he says. Mass applause from the room.

Some data indicates Philae may have touched down and then bounced off again. It is not clear. The lander may have jumped and started turning, says Ulamec.

12/11/2014 19:16

"We have very good data already," he says, despite the unstable data link. The instruments designed to analyse the comet's surface and insides have taken data.

"It is complicated to land on a comet," says Stephan Ulamec. "It is also very complicated to understand what has happend after this landing." They don't yet know whether Philae has fully attached to the comet.
