Artemis II

Completed

First crewed lunar flyby since Apollo 17

Artemis II was the first crewed Moon mission in over five decades. From 1 to 11 April 2026 a four-person crew aboard the Orion spacecraft flew a 9-day free-return trajectory that looped behind the lunar far side and brought them safely back to a Pacific Ocean splashdown. It was the qualifying flight for Orion ahead of Artemis III, the crewed Human Landing System test in Earth orbit planned for late 2027, and Artemis IV, the first crewed lunar landing planned for early 2028.

Followed by over 1.1 million space enthusiasts worldwide in recent months.

Mission overview

Lift-off came at 22:35 UTC on 1 April 2026 from Launch Complex 39B at Kennedy Space Center. SLS Block 1 carried Orion and the European-built service module on the second flight of the Artemis programme. Eight and a half minutes later the core stage separated and the upper stage delivered the crew to a high-energy Earth orbit for systems checkout.

After a partial orbit raise, the Interim Cryogenic Propulsion Stage executed the Trans-Lunar Injection burn that sent Orion toward the Moon. The trajectory was a true free-return: a single TLI insertion put the spacecraft on a path that lunar gravity would slingshot back to Earth without further engine firings. If every Orion engine had failed after TLI the crew would still have come home.

On day 4 the spacecraft swung behind the lunar far side at a closest approach of roughly 10,000 km above the surface, briefly becoming the farthest humans had ever been from Earth, around 406,770 km. The crew completed life-support stress tests, manual rendezvous practice, and live broadcasts before beginning the return coast.

Re-entry on 11 April 2026 used a skip-entry profile: the capsule dipped into the upper atmosphere to shed energy, bounced briefly back into space, then descended for the main entry. The AVCOAT heat shield reached about 2,800 C while Orion decelerated from roughly 40,000 km/h. Splashdown came in the Pacific Ocean at 00:07 UTC and the US Navy recovered the capsule with crew aboard.

Primary objectives

  • Qualify Orion for crewed deep-space flight including life-support, environmental control, and waste management over a full mission duration.
  • Validate the European service module propulsion and power systems with humans aboard.
  • Demonstrate manual proximity operations against the spent Interim Cryogenic Propulsion Stage.
  • Verify communication links with Deep Space Network ground stations from beyond the Moon.
  • Validate the skip-entry profile and AVCOAT heat shield at a crewed lunar-return velocity.

  87. Day 9.05Atmospheric Interface (Entry)Re-entry & Splashdown

    Orion reaches 120 km (75 miles) altitude at approximately 11 km/s (25,000 mph). The heat shield begins experiencing temperatures of up to 2,760 degrees C (5,000 degrees F). The crew experiences increasing G-forces as the atmosphere decelerates the capsule.

  88. Day 9.05Skip Re-entry ManeuverRe-entry & Splashdown

    Orion performs the skip re-entry technique: dipping into the atmosphere to decelerate, then briefly skipping back up to 60+ km altitude before plunging in for final descent. This spreads heat loads over two passes and allows precision landing targeting within 1.8 km of the recovery ship.

  89. Day 9.05Communications BlackoutRe-entry & Splashdown

    A sheath of superheated plasma surrounds the crew module during peak heating, creating a communications blackout lasting several minutes. The crew is on their own during this intense period.

  90. Day 9.06Drogue Parachute DeploymentRe-entry & Splashdown

    Two drogue parachutes deploy at approximately 7.6 km (25,000 feet) altitude, stabilising the crew module and slowing it from roughly 480 km/h (300 mph). The crew feels a sharp deceleration jolt.

  91. Day 9.06Main Parachute DeploymentRe-entry & Splashdown

    Three 35-metre (116-foot) main parachutes deploy at approximately 3 km (10,000 feet), slowing the crew module to roughly 32 km/h (20 mph) for splashdown. The crew confirm all three chutes are fully inflated.

  92. Day 9.06SplashdownRe-entry & Splashdown

    Orion splashes down in the Pacific Ocean off the coast of San Diego at 8:07 p.m. EDT. The approximately 10-day mission concludes with the first crewed return from lunar distance in over 50 years. The four astronauts become the first humans to fly around the Moon since 1972.

  93. Day 9.07Post-Splashdown StabilisationRe-entry & Splashdown

    The crew module is stable in the water with uprighting bags deployed if needed. The crew monitors cabin atmosphere and temperature while awaiting recovery forces. Navy divers approach by helicopter.

  94. Day 9.12Recovery Operations BeginRe-entry & Splashdown

    NASA and Department of War personnel, along with the USS John P. Murtha recovery team and Navy divers, secure the Orion capsule. The well deck flooding procedure begins to bring Orion aboard the ship. The crew egresses the capsule on the ship's deck.

Artemis II questions

What was Artemis II?
Artemis II was NASA’s first crewed mission to the Moon since Apollo 17 in December 1972. It launched on 1 April 2026 at 22:35 UTC from Launch Complex 39B at Kennedy Space Center carrying four astronauts aboard the Orion spacecraft atop an SLS Block 1 rocket. The crew flew a free-return trajectory that looped behind the far side of the Moon and returned home, splashing down in the Pacific Ocean on 11 April 2026 at 00:07 UTC.
Who flew on Artemis II?
The Artemis II crew were Commander Reid Wiseman (NASA), Pilot Victor Glover (NASA, the first Black astronaut to fly to the Moon), Mission Specialist Christina Koch (NASA, who already held the record for the longest single spaceflight by a woman), and Mission Specialist Jeremy Hansen (Canadian Space Agency, the first Canadian to fly to the Moon).
How long did Artemis II last?
Artemis II lasted 9 days and 1 hour from launch to splashdown. Orion travelled about 1.6 million kilometres in total, reached a maximum distance of approximately 406,770 km from Earth, and looped behind the Moon at an altitude of roughly 10,000 km above the lunar surface before returning to Earth.
What is a free-return trajectory?
A free-return trajectory is a flight path where a single engine burn (Trans-Lunar Injection) sends the spacecraft toward the Moon, after which lunar and Earth gravity carry it the rest of the way home with no additional firings required. The Moon slings Orion around its far side and redirects it back toward Earth. That makes it the safest possible trajectory for a crewed shakedown flight: even if the engines failed after TLI, the crew would still come home.
What happened during Artemis II re-entry?
Orion used a skip re-entry: it dipped into the upper atmosphere to shed speed, bounced back up briefly, then descended for final entry. The AVCOAT heat shield endured temperatures of around 2,800 degrees C while the capsule decelerated from roughly 40,000 km/h. A short communications blackout occurred during the hottest phase of entry. The capsule then deployed parachutes and splashed down in the Pacific Ocean for recovery by the US Navy.
How was Artemis II different from Apollo lunar flights?
Artemis II did not enter lunar orbit and did not land on the Moon: it was a single free-return loop around the lunar far side, similar in profile to Apollo 8 but flown to validate the Orion spacecraft for future surface missions. Artemis III, planned for late 2027, will be a crewed Human Landing System test in Earth orbit, comparable to Apollo 9. The first crewed lunar landing of the programme is Artemis IV, planned for early 2028, in which Orion will rendezvous in lunar orbit with a pre-positioned Human Landing System (either SpaceX Starship HLS or Blue Origin Blue Moon) before two astronauts descend to the south polar region.
Can I replay the Artemis II mission?
Yes. The ISSINFO Artemis tracker carries the full pre-rendered trajectory of Artemis II sourced from NASA JPL Horizons. Open the live tracker, select Artemis II from the mission menu, then scrub the timeline to any moment of the flight to see Orion’s position, velocity, distance from Earth and the Moon, the active mission phase, and the Deep Space Network status at that instant.
