The Starship moon landing number NASA and Elon Musk can’t agree on
NASA's Aerospace Safety Advisory Panel estimated 22 Starship launches are needed for a Moon landing, but Elon Musk disputes this, predicting 6-8 launches will be sufficient. The disagreement stems from differing estimates of the amount of propellant needed for the mission. Musk's estimate assumes a more capable Starship rocket than the one NASA is currently working with.
