A NASA authorization bill released by the House Science Committee Friday proposes major changes to the direction of the agency’s human spaceflight programs, with a goal to land crews on the moon by 2028, not the 2024 schedule set by the Trump administration.

The core stage of NASA’s first Space Launch System heavy-lift rocket arrived at the Kennedy Space Center on Tuesday evening aboard a specially-built barge, completing a voyage by sea from a test site in Mississippi to begin final preparations for the first flight of NASA’s Artemis Moon program. Ground crews plan to transport the core stage into the Vehicle Assembly Building beginning around 5:30 a.m. EDT (0930 GMT) Thursday to join its two solid rocket boosters.

NASA and industry teams at Cape Canaveral launched an Orion capsule on a three-minute atmospheric test flight Tuesday to prove the spaceship’s ability to escape from an exploding rocket during launch, demonstrating a key safety feature before astronauts ride the vehicle into deep space. Liftoff occurred at 7 a.m. EDT (1100 GMT).
