    One of the main reasons for using the moon is gravity - or, actually, the lack thereof.

    It takes a lot fuel (and space for said fuel) to lift significant weight of the surface of the Earth. Much less fuel is required to liftoff from the moon.

    WATCH LIVE: SARAH-1 MISSION

    SpaceX is targeting Saturday, June 18 at 7:19 a.m. PT, 14:19 UTC, for a Falcon 9 launch of the SARah-1 mission from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. A backup opportunity is available on Monday, June 20 at 7:19 a.m. PT, 14:19 UTC.

    The Falcon 9 first stage booster supporting this mission previously launched the NROL-87 and NROL-85 missions. Following stage separation, Falcon 9’s first stage will return to land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base in California.

    You can watch the live launch webcast starting about 10 minutes before liftoff.

    And the old reliable in Blacksburg (Benny Marzano's 28" pizza) has 2.5 times the surface area of the 18incher! Fueled a lot of engineering studying/homework sessions as well as life support after post-exam activities

    Cryo offloaded they are closing block valves, securing cryo storage areas, I think they still have to sniff ECS area which gets purged with gn2 before they open the pad for regular work. Calling it a success.

    That sounds like a 2nd shift endeavor. I'm not really sure.

    What about the hydrogen leak at the quick disconnect?

    Hydrogen boys are gonna be busy doing full system torques. Once cryo flows through those lines every nut has to be bumped not just looked at. The stainless contracts and expands so much if the metal is porous at all, moisture will comprimise it and the studs will literally crumble. Not sure if they are planning a wdr5 or not. We shall see.

    A lot of differences but simply mind boggling to see the relative size difference between Saturn/Jupiter and their moons vs Earth & ours.
