Watch Live: NASA's Artemis II Mission Returns to Earth | WSJ
NASA's Artemis II mission successfully completed with the Orion spacecraft 'Integrity' splashing down in the Pacific Ocean at 7:07 PM Central time, returning four astronauts safely from their historic lunar flyby mission. The crew of Reed Wiseman, Victor Glover, Christina Cook, and Jeremy Hansen were recovered by Navy teams and reported to be in excellent health after their 9-day journey around the Moon.
Summary
The Artemis II mission concluded with a textbook splashdown in the Pacific Ocean southwest of San Diego at 7:07:27 PM Central time on what appears to be April 10th, marking the first time astronauts have returned from lunar vicinity since Apollo 17 in December 1972. The mission lasted 9 days, 1 hour, 32 minutes, and 15 seconds, covering approximately 694,481 miles from launch at Kennedy Space Center to Pacific recovery.
The entry sequence began with Integrity entering Earth's atmosphere at 400,000 feet traveling at 34,882 feet per second. As predicted, communications were lost for exactly 6 minutes during peak heating when temperatures reached 4,000-5,000°F due to plasma buildup around the spacecraft. Multiple airborne assets maintained visual contact throughout the blackout period. The parachute deployment sequence executed flawlessly - first the forward bay cover parachutes, then drogue parachutes for stabilization, followed by three main parachutes 116 feet in diameter that slowed the spacecraft to 19 mph for splashdown.
Commander Reed Wiseman reported 'four green crew members' multiple times, indicating all astronauts - himself, Victor Glover, Christina Cook, and Jeremy Hansen - were in excellent health. Recovery operations involved over 40 Navy and NASA personnel in six boats from the USS John P. Murtha. After some initial communication difficulties with satellite phones and SAR radios, the crew was successfully extracted onto an inflatable 'front porch' raft before being hoisted individually by two Navy helicopters back to the recovery ship.
NASA Administrator Jared Isaacman, present on the recovery ship, emphasized this mission's significance as the beginning of sustained lunar exploration rather than a one-time achievement. He highlighted international cooperation, including Canadian astronaut Jeremy Hansen and the European service module, as well as ongoing preparations for Artemis III with components already arriving at Kennedy Space Center. The mission represents humanity's return to deep space exploration with plans for lunar surface operations by 2028 and eventual Mars missions.
Key Insights
- Flight Dynamics confirmed the trajectory of Integrity coming through Earth's atmosphere was so precise they've never seen anything line up on a ground track like today's entry
- The mission lasted exactly 9 days, 1 hour, 32 minutes, and 15 seconds, covering 694,481 miles from Kennedy Space Center launch to Pacific splashdown
- Communications blackout lasted exactly 6 minutes during peak heating when temperatures reached 4,000-5,000°F due to plasma buildup around the spacecraft
- Reed Wiseman reported 'four green crew members' meaning all astronauts were in excellent health, clarifying this referred to their condition not complexion
- Administrator Isaacman emphasized this is not a once-in-a-lifetime event but the beginning of frequent lunar missions, with plans to land on the moon in 2028 and build a base
- The recovery operation required over 40 Navy and NASA personnel in six boats, with crews spending four hours in the water to stage equipment before splashdown
- Main parachutes were 116 feet in diameter and 265 feet long when reefed, ultimately slowing Integrity from 33 times the speed of sound to 19 mph at splashdown
- International cooperation included Canadian astronaut Jeremy Hansen and European service module, with Italy signing a memorandum to build a habitation module on the moon just 48 hours before launch
- Entry interface occurred at 400,000 feet traveling 34,882 feet per second, marking the first traces of Earth's atmosphere for the returning crew
- The mission marked the first time astronauts returned from lunar vicinity since Apollo 17's splashdown on December 19, 1972, ending a 53.5-year gap
- Components for Artemis III are already arriving at Kennedy Space Center, with core stage rolling out April 20th and mobile launcher returning to vehicle assembly building
- Weather conditions at splashdown were ideal with scattered clouds, 10-knot winds, and 4-foot wave heights in the Pacific southwest of San Diego
