Wow! What will the total mass of Mk1 be?
Mk1 ship is around 200 tons dry & 1400 tons wet, but aiming for 120 by Mk4 or Mk5. Total stack mass with max payload is 5000 tons.
Any composites planned to reduce the weight by mk4 or mk5?
With rare exceptions, composites would make Starship heavier. They don’t stand up well to high temperatures, but steel does great.
When do you finish installing them? pic.twitter.com/l2XLy4MN7V— 𝚇 𝚃𝚎𝚜𝚕𝚊 (@ex_Tesla) September 26, 2019
