As I write, mission control at ESA (European Space Agency) dutifully prepare Rosetta for her assisted suicide. In less than 6 hours (twenty minutes either side of 7:20 am ET to be precise), Rosetta enters controlled descent into the pits of Deir el-Medina on comet 67P/Churyumov-Gerasimenko.
“The target area is home to several active pits measuring over 100 meters across and 60 meters deep [about 100 yards wide and 60 yards deep], from which a number of the comet’s dust jets originate. Some of the pit walls also exhibit intriguing meter-sized lumpy structures called ‘goosebumps’, which could be the signatures of early cometesimals [i.e, the building blocks of comets] that agglomerated to create the comet in the early phases of solar system formation. Rosetta’s final descent may afford detailed close-up views of these features.” – ESA
