Four astronauts have returned to Earth after completing the first crewed mission to the vicinity of the Moon in more than 50 years. NASA's Artemis II crew splashed down in the Pacific Ocean off the coast of San Diego on 10 April 2026, ending a nearly 10-day journey that broke records, tested critical spacecraft systems, and marked the beginning of a new era in human space exploration.
Commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen lifted off on 1 April aboard NASA's Orion spacecraft, named Integrity by the crew. On 6 April, the mission reached its most dramatic moment when the crew flew around the far side of the Moon, travelling 252,756 miles from Earth and surpassing the distance record previously set by the Apollo 13 crew in 1970.
What the Mission Set Out to Do
Artemis II was never intended to land on the Moon. Its purpose was to test the Orion spacecraft's systems with humans on board for the first time, gathering data that uncrewed missions simply cannot provide. The crew evaluated life support systems, performed manual piloting exercises, and took part in science investigations studying how the human body responds to deep space radiation and microgravity. All of this data will inform how NASA designs and operates future missions to the lunar surface.
The Heat Shield Question
One of the most closely watched aspects of the mission was the performance of Orion's heat shield during re-entry. After Artemis I in 2022, engineers found unexpected cracking and erosion in the shield's Avcoat material. NASA modified the re-entry approach for Artemis II, using a steeper trajectory to reduce the time the shield was exposed to extreme heat. The crew re-entered the atmosphere at 35 times the speed of sound, and all four astronauts emerged safely. Engineers are now conducting a full inspection of the returned capsule to assess how the shield performed, with findings expected to shape the design used on Artemis III.
A Crew of Firsts
The mission also carried significant historical weight. Victor Glover became the first person of colour to travel beyond low Earth orbit. Christina Koch became the first woman to do so. Jeremy Hansen became the first non-American citizen to travel beyond low Earth orbit. These are not minor footnotes; they reflect a programme designed to broaden who gets to participate in deep space exploration.
What Comes Next
With Artemis II declared a success, NASA turns its attention to Artemis III, currently planned for 2027. That mission aims to land astronauts on the lunar surface for the first time since Apollo 17 in 1972. Engineers must address several issues identified during Artemis II, including a valve in the service module requiring redesign. The path back to the Moon's surface is now open, but there is still considerable work ahead before boots touch the lunar soil once more.
