Rosetta comet landing: What data can we expect?
First pictures from the space-probe clinging to the surface of a comet have been released. The Philae probe beamed them back to Earth early Thursday morning. The lander bounced at least twice during the landing, but scientists say it is now stable and can start gathering data. NASA Astronaut John Grunsfeld joins CBSN with more on what kind of information will be collected.
