To be clear, Starship can launch through clouds, but SpaceX wanted to be able to observe the rocket during the launch. Then, there is the tanker variety, which will launch into orbit, dock with the depot Starship, transfer propellant to it, and then land back on Earth. But, even if SpaceX stuffed the Starship depot with all the insulation in the world, it wouldn’t stop this loss of fuel. That is equivalent to one of the four launch pads having a launch delay similar to Flight 13 each week. So, there is a notable chance that a Starship lunar mission will end in a catastrophic failure in LEO rather than meeting NASA astronauts around the Moon.
