NASA and SpaceX sign an agreement for a second crewed lunar landing.

Before the end of this decade, NASA and SpaceX will launch a second mission to land astronauts on the lunar surface.

The space agency chose SpaceX last year to perform the first crewed lunar landing in 50 years using a modified version of its Starship spaceship that is currently under construction. The first mission might happen as early as 2025, and the second landing could happen as late as 2027.
