SpaceX, billionaire Elon Musk's commercial rocket company, says it's working on a "simplified" plan for its Starship to land astronauts on the moon.

After acting NASA Administrator Sean Duffy this month called out SpaceX for Starship delays, Elon Musk's company has come back with an update defending its progress and offering a speedier plan to get astronauts back on the moon as part of the Artemis program.

One reason SpaceX is pouring so much money into Starship development at the company's Boca Chica/Starbase production/testing complex is to satisfy a $4.4 billion contract with NASA to put U.S. astronauts back on the moon for the first time since 1972.

Trump said Jared Isaacman's astronaut experience and dedication to "advancing the new space economy make him suited to lead NASA into a bold new era."

Ahead of Jared Isaacman’s renomination for the position of NASA’s administrator, a dispute between him and its acting chief Sean Duffy spilled into the open, with potentially profound consequences for the U.

SpaceX said it has pitched NASA a "simplified mission" to put astronauts back on the moon following criticisms over delays by Sean Duffy, the space agency's acting administrator.
