Lift-off for NASA mission to collect grains from an asteroid that may be on collision course with Earth

It’s been a great few weeks for missions to small, primitive bodies. We’ve just about digested the latest news from the Ceres asteroid and rejoiced at the recovery of the comet-lander Philae, in time to wish a safe journey to NASA’s exciting new mission to Asteroid 101955 Bennu. OSIRIS-REx (short for Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorers – which is a bit of a mouthful) is to launch from Florida’s Cape Canaveral at 7:05pm EDT on September 8.
