Rosetta space mission makes historic landing

A European robot probe has made the first, historic landing on a comet, but its status is uncertain after harpoons failed to anchor it to the surface.

Officials said the craft may have lifted off the comet after touchdown before returning to the surface.

The "first" landing on Comet 67P/Churyumov-Gerasimenko was confirmed at about 1605 GMT.

David Shukman reports.
