Last Comet post for a while maybe

One last thing that I wanted to say about comets that may be interesting but uncontrovercial, was about the potential usage of the "atmosphere" of the comet for cometary bases. By this I do not mean the corona, but by sealing off one of the "jets" partially or completely and having a robot within the higher pressure gas chamber thus formed, the volatile cases and solids, including water, HCN and organics, could be used to generate fuel for a space base, and the atmospheric pressure inside may reduce the need for exceedingly bulky spacesuits for human visitors, although the poisonous nature of the HCN may be problematic.
