They're just getting warmed up.
There's still plenty more work to be done. Just days before the static fire test, Musk said in a live Twitter discussion that SpaceX will need to make "well over a thousand" changes ahead of its next launch,The most significant of those tweaks is switching to what's called a "hot staging" approach for achieving a separation of the rocket's two stages, which failed to decouple during its first orbital flight after several engine failures.
With hot staging, the second stage — in this case the Starship spaceship — fires up its engines while some of the engines of the first stage, the Super Heavy booster, are still on. Typically, a booster is completely shut off before the engines of the spaceship are activated. According to Musk, using hot staging will prevent a temporary loss of thrust during the separation sequence, bumping up Starship's already gigantic payload capacity of 100 metric tons by ten percent.
But that means that SpaceX will have to fit the reusable booster with an extension that will direct the exhaust of the upper stage away from the rocket so it doesn't get destroyed.The launch date for the second flight is still up in the air, though Musk remains ambitious. "We think, probably, the launch pad upgrades, and the booster and ship, are ready in about six weeks," Musk said, per
