Web1 hour ago · The stainless steel Starship has 33 main engines and 16.7 million pounds of thrust. All but two of the methane-fueled, first-stage engines ignited during a launch pad test in January — good enough to reach orbit, Musk noted. Given its muscle, Starship could lift as much as 250 tons and accommodate 100 people on a trip to Mars. Web@article{osti_6534128, title = {Topology of tokamak orbits}, author = {Rome, J.
