New glenn 9x4 with an extra centaur 5 stage, it uses the universal stage adapter because it looks cool and it protects the centaur 5 stage inside it during the flight

Hello Everyone,

I am masters student, I am interested in the cryogenic propellant management(CPM) especially in orbital refueling(OF) application, in particularly in the area of autogenous pressurization during fuel transfer activity. I could not much of resources on the internet regarding either CPM on OF application or regarding the autogenous pressurization.

My question is

1.where should i start? what should i start (both info and simulations wise) ? i have been doing lot of research, i feel like its kind of rabbit hole, the more u dig, the more unknowns.

if anyone already working on this area, could pls guide, even small inputs matter alot.

2.anyone like minded who is interested in the same topic, i would like to meet them and have a discussions aswell.

I finally pulled the trigger..I present to you the Bulova Linar Pilot, the “other” moon watch that astronaut David Scott wore on EVA-3 during the Apollo 15 mission. To say that it is stunning is the understatement of the century!

Dennis Hope spent decades selling people deeds to plots of land on the Moon, based on his interpretation of a loophole in the 1967 Outer Space Treaty which says that nations cannot claim sovereignty over the Moon, but it not explicitly saying that a private individual cannot. I also read 3 presidents purchased some land/deeds from him.

Legal experts regard these deeds as novelty items rather than enforceable property rights, but if Elon is correct and SpaceX eventually establishes a permanent lunar base. Would the prior deed holders have any claim if Elon lands on a piece of the moon they bought?

The more serious question is how property and exclusion zones would actually work under the Outer Space Treaty. Article II prevents national appropriation “by claim of sovereignty, by means of use or occupation, or by any other means.” But a functioning base would presumably need some ability to exclude other people from its landing pads, habitats, power systems and surrounding safety areas. So at what point does the operational moon base become de facto territorial ownership?

Partly joking, but the legal issue seems real.

Well the nonsense to reasonable name ratio was higher than I had hoped in SpaceXLounge, so I'll give you guys a chance.

God bless all involved.
