the smell the astronaughts smelled would be their air supply
That last one put some shit in perspective.
NO. The smells that astronauts describe come from polycyclic aromatic hydrocarbons that attach to the suits. Also, some of this information is a little bit dated. Aerogel was previously the world’s lightest material with a density of 0.18 mg/cm^3. Graphene aerogel is 0.16 mg/cm^3.
I love knowledge.
