Long story short, they launched an investigation into the Artemis I heatshield and found that during reentry, gases generated inside the Avcoat (the shield's ablative material) could not vent properly which caused pressure to build up, leading to cracking of charred chunks but well within margins. They are adjusting Orion's reentry profile for Artemis II to a steeper angle to reduce the dwell time at altitudes where this outgassing occurs, so it will spend about 8 minutes rather than the 15 minutes in these conditions.

This approach essentially reverse artimes' approach (shallow, longer, skip-like descent) to Apollo's approach (steeper, shorter, ballistic descent). Funny thing is that Artimes uses Apollo's heatshield material and ends up in the same descending profile.

Yah but Apollo had a single piece of avcoat for its heatshield whereas Orion has 186 individual pieces of avcoat. It is essentially a different heatshield with different mechanical properties.

Artemis II successful launch so far! Obviously this is like a ~10 day mission so it is only about ten minutes in so far, but just huge to get lift-off and into space.

While in orbit around Earth, the Artemis II crew called down to the mission team on the ground to report a problem with their toilet.

They noticed a blinking fault light that NASA’s associate administrator Amit Kshatriya called a “controller issue” in a news conference, one that would take some hours to troubleshoot.

Bruh the US and their faulty toilets.
