I want to pick up from the last time I posted about Rosetta, which was this thread

Thread: Rosetta Comet chaser closing in- *** GLP has discovered a new asteroid - New picture page 7, no name yet, share your thoughts ***

Which started off being about the "big burns". These were long duration engine burns, designed to match Rosetta's speed to that of comet 67P. Those have now been completed and as of today Rosetta is just 4700km from the comet with just 3 small burns left in the rendezvous part of the mission. Rosetta is now closing with the comet at only 20mph ( 9m/s )
