At the core of Isaacman’s concerns is the low flight rate of the SLS rocket and Artemis missions. During past exploration missions, from Mercury through Gemini, Apollo, and the Space Shuttle program, NASA has launched humans on average about once every three months. It has been nearly 3.5 years since Artemis I launched.

NASA Administrator Jared Isaacman announced significant changes to the agency's Artemis program, which aims to land on the moon in 2028.

NASA has set a new April 1 launch target for Artemis II, the first crewed mission to the moon in more than 50 years.

NASA has replaced two bigwigs in its human spaceflight program, just a week after releasing a report criticizing how the agency handled the first crewed flight of Boeing's Starliner astronaut taxi.

BREVARD COUNTY, Fla. - Amid ongoing delays with its Artemis II mission, NASA on Friday announced major changes to its Artemis program and plans to send astronauts to the moon.

The overhaul in the flight lineup came just two days after NASA’s new moon rocket returned to its hangar for more repairs, and a safety panel warned the space agency to scale back its overly ambitious goals for humanity’s first lunar landing since 1972.

NASA will host a news conference at 3 p.m. EDT on Thursday, March 12, at Kennedy Space Center to highlight progress toward the Artemis II mission, the first crewed flight of the Artemis program, which is intended to carry astronauts around the Moon.

Artemis II has been plagued by similar issues to those faced by its predecessor, leading NASA to shake up its plan to return humans to the Moon.

NASA is aiming for an April 1 launch date for a mission that will send astronauts around the moon and back as part of its ambitious lunar landing program. Four astronauts will fly aboard NASA’s Orion spacecraft,

NASA's moon landing program delay represents the latest in in technical, budgetary, workforce and public perception challenges plaguing the agency.
