Sorry guys, I said I’d post the second half of that thought today (the one about how to use dual-launched EELVs for manned missions). But I’m exhausted. Been doing far too many cycles of stay up till 1am, then get up at 6:30 or 7am over the past two weeks. I’m going to bed. Hopefully [...]

I’ve been without net access for a few months and still don’t have a valid email after moving out of the house. I don’t have anything interesting to post at this time, especially as I seem to have missed a lot, but will throw ideas out there when that changes.
