'It's 13 minutes of things that have to go right': Artemis II splashes down despite faulty heat shield.

The article focuses on NASA's Artemis II mission, the first crewed lunar mission since Apollo 17 in 1972, highlighting the critical challenge posed by a known flaw in the Orion spacecraft's heat shield. Despite cracks and material loss observed during the unmanned Artemis I mission due to trapped gas pressure beneath the shield, NASA chose to proceed with the same design for Artemis II, modifying the spacecraft’s reentry trajectory to maintain higher temperatures and prevent gas buildup. The four astronauts successfully executed this risk-managed reentry, enduring extreme speeds and temperatures, and safely splashed down in the Pacific Ocean. The mission demonstrated NASA’s reliance on extensive testing and data to mitigate risks associated with the heat shield’s vulnerability. [Extracted from the article]
