Artemis Core Stage: Built To Survive Extreme Cold 4 hours ago Updated: April 25, 2026, 2:23 pm EDTPublished: April 25, 2026, 2:23 pm EDTNASA's Artemis III core stage holds 733,000 gallons of liquid hydrogen at minus 423 degrees, cold enough to shatter normal…

Why it matters

See how NASA engineered an aluminum-lithium alloy that stays flexible 300 degrees colder than Antarctica's worst day, and why foam insulation prevents the ice buildup that doomed Columbia during launch in 2003.

Common ground

The clearest point to anchor on is this: NASA's Artemis III core stage holds 733,000 gallons of liquid hydrogen at minus 423 degrees, cold enough to shatter normal metal like glass.
