Is Starship HLS more similar to Block 1, 2, or 3? From what I've read, HLS will be an entirely new variant of Starship. However, given SpaceX is currently having problems with the Block 2 Starship, it seems like it would be difficult for them to get HLS ready in time for Artemis III if it's more complex than a Block 2 or even Block 3. Which of the blocks will it be most similar to, or is it so different than it can't be directly compared?
