Just heard via Dennis Wingo that my former colleague at Rockwell has died. He, Bob Waldron and I were working lunar ISRU in the early 90s, during the SEI scare. Condolences to his other friends and family. We’re losing a lot of visionary people, just as we’re finally on the verge of breaking out.
Here is an interview with Ed on lunar settlements.
That was a very good interview.
I was unaware of the potential ammonia on the moon, which greatly simplifies the nitrogen problems.
Condolences on losing a friend.
During the interview, Ed estimated 13 to 14 years to break-even on the moon. Does the potential payload capability of the starship change this time-frame? And are there more accurate or more optimistic numbers on the concentration of ammonia?
