Maybe I'm just dumb. Maybe I'm missing something. But I just can't understand why NASA protocol is to take considerable amounts of mass (empty packing materials, small non-working stuff like pens, feces, etc.) and drop it into the atmosphere.
I mean, hey, how much does it cost per kilo to get something into Earth orbit?
And there's no viable solution possible to take our leftovers and turn them into something useful? I simply don't believe it.
