Artemis II astronauts bet their lives on NASA's maths being right tonight: Crew will face a 24,000mph re-entry into Earth's atmosphere - with just a 3-INCH shield to protect them from the 2,760°C heat

Artemis II astronauts will re-enter Earth's atmosphere at 24,000mph, relying on NASA's calculations to navigate extreme conditions. A 3-inch shield must protect them from 2,760°C heat during the critical re-entry phase.
