The first chemical analysis of Comet 67P/C-G’s coma
The Rosetta science team today released their first analysis of the chemical make-up of Comet 67P/C-G’s coma, finding that not surprisingly it is made up mostly of water, carbon monoxide, and carbon dioxide.
However, ROSINA [the instrument on Rosetta for doing this analysis] has made the surprising observation that the ratio between these species varies quite significantly, depending on where in the coma Rosetta is. Sometimes carbon monoxide is almost as abundant as water; sometimes it’s only around 10%. In addition, ROSINA has not only detected these main species already, but many of the expected minor ones, such as ammonia, methane, and methanol.

What technology and how much will it cost in developed country’s taxes for the human race to control the CO2 emissions of comets ? (scsm)
You can believe that there are people that draw breath who would certainly entertain the idea that comets and their emissions need to be controlled because they are polluting the space that the earth exists in. Bet on it.
