NASA Artemis II splashes down in Pacific Ocean in ‘perfect’ landing for Moon mission

NASA's Artemis II returns four astronauts safely from a record-breaking 252,760-mile lunar orbit mission, marking humanity's first crewed Moon flight in 50+ years with groundbreaking new surface imagery.

Here's how to watch the Artemis II splashdown

NASA's Artemis II successfully flies four astronauts around the Moon at 4,067 miles from the surface, setting a human distance-from-Earth record and proving the mission architecture needed for Artemis III's lunar landing.

Artemis II and the invisible hazard on the way to the Moon

Artemis II (launched April 2026) deploys advanced radiation dosimetry and organ-chip biomarkers to characterize deep-space radiation effects on human physiology for the first time since Apollo, directly informing safe crewed protocols for lunar and Mars missions.
