The upgrades are the main reason SpaceX has scrapped the Starship SN12, SN12 and SN13, instead opting to go straight to the SN15.
One hopeful fan tweeted: “If SN15 doesn’t land, I’ll explode.”
Another person said: “@elonmusk you must land SN15 on Star Wars Day. May the 4th be with you!”
And a third person said: “Starting the #SN15 launch day with the 1967 Classic film “Journey To The Far Side Of The Sun”.
“This is the film Starship makes me think of every time they fly one.
“Really hoping SN15 and those Raptors land today to prove the concept of the flip.”
