NASA's Artemis program has hit a few bumps on the road to the moon. The plan to land astronauts there by 2026 has been pushed back to at least mid-2027. This isn't the first delay for the program, which has been adjusting its timeline as it prepares for its first crewed mission to the moon since the 1970s.

One big issue is with the Orion crew capsule's heat shield. During the uncrewed Artemis I mission in 2022, the shield got charred and eroded in an unexpected way. NASA has been working to understand and fix this problem.

The heat shield issue is linked to how Orion reenters Earth's atmosphere. It uses a "skip reentry" method, like a rock skipping on water, to lose speed. But this method caused heat to build up inside the shield, leading to the wear.

NASA plans to fly Artemis II with a different trajectory to solve this problem. The agency is also looking at the bigger picture. The target landing date for Artemis III, the mission to put astronauts on the lunar surface, is getting closer to the original 2028 goal.

There's more to the story. NASA wants to land astronauts at the moon's south pole, where there might be water ice. Water ice could be turned into rocket fuel or drinking water. This is important because other countries, like China, have their eyes on the moon too. China plans to send astronauts to the moon by 2030.
