Files to 'print your own' Rosetta comet (BBC)

Europe's space agency (Esa) has finally released a proper model for the shape of Comet 67P/Churyumov-Gerasimenko.
The organisation's Rosetta mission will try to put a small robot on the surface of this "ice mountain" on 12 November.
The model provides some further details on the comet's size, and also allows enthusiasts to print their own 3D version of the duck-shaped object.
Rosetta has been flying around 67P since August, and could get as close as 10km, if it is deemed safe to do so.
Esa Flight Director Andrea Accomazzo told the International Astronautical Congress in Toronto on Friday that a final decision on this matter would be made next week.
