Thank you. ohn Batchelor and I welcomed Dr. David Grinspoon ( to Hotel Mars to discuss Comet 67P, the Philae lander, and what has been learned so far from the science instruments aboard Philae and the orbiting Rosetta spacecraft. We discussed the likelihood of Philae waking up and working again as the comet gets closer to the sun, the unfortunate landing of Philae and its bounces, plus the discovery of organics for the comet. We also talked about the chances of finding amino acids & specific proteins once the data is evaluated. I asked how high Philae bounced on the landing and how close it came to escape velocity given the low gravity on 67P and the very light mass of Philae equal to about a paperclip or piece of paper. We also talked about the comet ice and if the ice would melt or survive were a comet like this to enter the earth's atmosphere. Please post your comments/questions on TSS blog. You can email Mr. Batchelor or Dr. Grinspoon through me.
