Before sending people to moon NASA will send rovers. Job 1 should be finding several good safe LEVEL landing areas with firm regolith for SpaceX HLS or other lander. Such an obvious solution to the tip over problem.

@FelixSchlang Very much. The increasing importance of battery technology and battery management during races will add quite a new dimension to the races. Should be wonderful. Max/Lando competition will be fun 😊

@SpaceX Because booster is damaged but standing, I think a crane should be brought to stabilize it where it is so it can be examined in place safely.

equations to give azimuth and elevation from a particulsr position and time

@MarcusHouse @SpaceX Was Flt 10 booster grid purposely frozen to test 3 grid control? When nat gas pipeline to be installed for purified CH4 production at launch site? When H2O pipeline to pad? When Flt 11?

[CaptainBill @av8SWA]

@SpaceX With 25 launches per year initially and many more later, a water main would save a lot of truck deliveries and CO2 emissions. It should cost between $1 to $2 million per mile to install a 12-in water main.

@SERobinsonJr @SpaceX Send Starship with door&hoist, solar cells, large bat. Cargo of Cynertruk w larger bat and solid tires, 2 Optimus, helicopter, recharging capability for truck $ bots. AI could operate and retrieve samples plus new ones. Uses mostly current tech

[CaptainBill @av8SWA]

@Phrankensteyn With two operating engines using grid fin/engine gimbal/thruster control can booster achieve vertical attitude, catch pin orientation, X Y Z position and velocity to be caught?

[CaptainBill @av8SWA]

@Phrankensteyn @SpaceX airliners can withstand engine failure safely. Will an engine failure during catch cause crash. Relight additional engine quickly to continue or execute wave off into the Gulf. Waveoff fuel required?

[CaptainBill @av8SWA]

@SpaceX @FelixSchlang slide rails are added to boosters to facilitate catching. What can be done with ship so chopsticks don't tear up fragile heat tilles?

@gunsnrosesgirl3 Honesty

[CaptainBill @av8SWA]

@pickover It takes a combination of hexagons and pentagons to tile a soccer ball. May be other combos. I believe spectre tiles and pentagon will also tile over a sphere but I can't find a reference. Do you have one. I was astounded by spectre. Penrose-1

[CaptainBill @av8SWA]

@pickover Or radon?

[CaptainBill @av8SWA]

@pickover What about chlorine and fluorine?

[CaptainBill @av8SWA]

@elonmusk @SpaceX do we have any information yet regarding the durability of the stainless steel in the area of the two omitted tiles?
