>>12469884it's a carbonaceous asteroid, so I'm betting it has lots of hydrogen and carbon. Iron wouldn't surprise me though.
>>12469981the gas was a bonus sample in addition to what they already got. I can't wait to find out what it is!
>>12470133Anon, the big deal here is getting the same elements we have on earth, but at a lower delta V cost to put in orbit. Carbonaceous asteroids could have a decent amount of water which could be used as propellent. Delta V cost to asteroids is pretty low and if you can extract water on the asteroid you can use it as propellant to get the rest of the water home. Finding amino acids and other prebiotic molecules would be cool too.
