On 27 June 2011 we were invited to satellite operator and communication specialist Inmarsat's London HQ, for a very special presentation by the NASA crew of Space Shuttle Discovery. The astronauts described their experiences on STS-133, the final mission of the Discovery orbiter vehicle, which blasted off on 24 February for its last-ever flight before retirement - a 12 day trip to the ISS.
