And snaps pics of Mars The comet-hunting spacecraft Rosetta has sent back its first sighting of the asteroid 21-Lutetia, one of two rocky bodies it will study en route to the comet 67p Churyumov-Gerasimenko. It will not get anywhere close to the rock for more than two years, but has already begun sending back preliminary data.â¦
