How NASA’s Artemis II became a make-or-break moon shot

The new plan came after extensive testing, according to NASA, and Isaacman said in January that he had “full confidence” in the heat shield.

Wiseman gave a similar assessment: “If we stick to NASA’s new planned re-entry pathway, then this heat shield will be able to fly safely,” he said at a media event in July.

Two years before the moon landing

Another key criticism of the Artemis program concerns the years between launches. Nearly four years have passed since the Artemis I flight, and until last month it was planned to wait another two years for the next launch after Artemis II.

Critics argued that the long intervals made the program less secure because teams could not improve and iterate quickly, as commercial space companies like SpaceX do.

“The fact that the Space Launch System cannot be launched very frequently is a huge structural and safety risk that has been known for a long time,” Dreier said, adding: “You only have a limited number of chances to know your failure modes.”

To address these issues, Isaacman recently revamped the Artemis program. The changes, which he announced less than three months into his tenure at NASA, include additional missions and an increase in the pace of launches.

Now, the Artemis III mission, which was originally scheduled to send astronauts to the Moon in 2028, will launch into low Earth orbit in mid-2027 for technology testing and demonstrations. NASA’s complex plan to reach the lunar surface involves a second spacecraft — a lander built by SpaceX or Blue Origin — that would dock with Orion in lunar orbit and then transport astronauts to the Moon. Artemis III aims to practice such a maneuver. The commercial sector has also faced setbacks: A report released this month by NASA’s Office of Inspector General said SpaceX’s Starship lander was “at least two years behind schedule, with additional delays expected.”

Under its new plan, NASA aims to put boots on the Moon with the Artemis IV mission in 2028.

Under the changes, Isaacman said, the goal is to launch the Space Launch System rocket approximately every 10 months, rather than every three years.

All of this depends on the success of the Artemis II mission, which could give NASA – and perhaps the American public – a much-needed boost.

“Whenever the White House really needs good news, they go to NASA,” Melroy said.
