Why do we need zero boil-off, again? Oh right, we don't. Small amount of boil-off is fine.

Jeff Foust @jeff_foustMeyerson: Blue willing to invest in “Blue Moon” lunar lander concept in partnership with NASA; return to Moon worthy national goal.
Eric Berger Verified account @SciGuySpaceEric Berger Retweeted Jeff FoustWilling to invest "significantly." Which IMO is significant.

So far it's pleasing to hear about the Blue Moon Lander. Perhaps it will be to Luna what Red Dragon may be to Mars. ..
Blue Moon is designed to fly on any launch vehicle, including SLS, Atlas V, Vulcan and New Glenn. Delivering large payloads to the lunar surface, Blue Moon can help put astronauts on the moon – this time to stay. #BlueMoon #Apollo50th
Charania said “we’re actively working on the descent stage for Blue Moon, the capabilities, the partnerships that are required to enable that service … to start going back to the moon with larger and larger payloads.”
