NASA Worried Starship Issues Could Delay Moon Landing

NASA is concerned that the lunar lander version of SpaceX's Starship vehicle will not be ready in time for the Artemis 3 mission in late 2025, given the amount of work needed to get the vehicle ready. Each Starship lander mission requires launching the Starship lander itself as well as several "tanker" Starships to fuel the lander in Earth orbit before it goes to the moon. SpaceX will carry out an uncrewed Starship lunar landing, and also must demonstrate cryogenic fluid transfer in Earth orbit before Artemis 3.
