Artemis II: NASA’s Historic Return to Lunar Orbit
For the first time in over five decades, humans have ventured beyond low Earth orbit. NASA’s Artemis II mission, which launched on April 1, 2026, marks a pivotal moment in space exploration, sending a crew of four astronauts on a ten-day lunar flyby. This mission isn’t just about the journey around the Moon; it’s a critical test of the deep space systems required to eventually land humans on the lunar surface and, eventually, send crews to Mars.
The Mission Profile: Rocketry and Spacecraft
Artemis II is the first crewed flight of the Space Launch System (SLS) rocket and the Orion spacecraft. While the uncrewed Artemis I mission in 2022 proved the basic viability of the hardware, Artemis II demonstrates the capabilities needed to sustain human life in deep space.
The crew named their Orion spacecraft “Integrity.” Developed by Lockheed Martin (with the European Service Module built by Airbus), Orion serves as the exploration vehicle that carries the crew to the Moon and ensures their safe return to Earth. The entire launch stack stood 322 feet tall, propelled by the massive lift capacity of the SLS rocket from Launch Complex 39B at the Kennedy Space Center in Florida.
The Artemis II Crew
The mission is powered by a diverse crew of four astronauts:
- Reid Wiseman
- Victor Glover
- Christina Koch
- Jeremy Hansen
Breaking Records and Capturing History
The Artemis II mission has already achieved several historic milestones during its 685,000-mile journey. Most notably, the crew eclipsed the record for the farthest human spaceflight, surpassing the distance of 248,655 miles set by the Apollo 13 mission in 1970.
Beyond the technical achievements, the crew has provided the world with stunning visual evidence of their journey. On April 7, 2026, the astronauts captured a total solar eclipse from space and beamed official “Earthset” photos back to Earth. These images and communications, including a long-distance call to the International Space Station on Flight Day 7, highlight the operational success of NASA’s deep space communication systems.
The Journey Home and Splashdown
As of April 8, 2026, the crew is currently on their return leg to Earth. Following the completion of the first return correction burn on Flight Day 7, the spacecraft is heading toward the Pacific Ocean.
The splashdown is tentatively scheduled for Friday, April 10, at 8:07 p.m. ET off the coast of San Diego. The recovery operation will be led by the USS John P. Murtha. For a successful recovery, NASA requires specific weather conditions: winds must remain below 28.7 miles per hour, wave heights must be under six feet, and there must be no rain or lightning within 30 nautical miles of the splashdown site.

- Launch Date: April 1, 2026.
- Duration: 10 days.
- Primary Goal: Test deep space systems and the Orion spacecraft for future Moon and Mars missions.
- Historic First: First crewed flight beyond low Earth orbit since Apollo 17 in 1972.
Frequently Asked Questions
Did the Artemis II crew land on the Moon?
No. Artemis II is a lunar flyby mission. Its purpose is to test the spacecraft and systems with a crew on board before NASA attempts a lunar landing with subsequent missions.
How does this differ from the Apollo missions?
While Apollo focused on landing humans on the Moon, the Artemis program aims for a long-term return. This includes building a permanent lunar base and using the Moon as a stepping stone for future missions to Mars.
Who is recovering the spacecraft?
The USS John P. Murtha is the planned recovery vessel for the Orion spacecraft’s splashdown in the Pacific Ocean.
Looking Ahead: The Path to Artemis III
The success of Artemis II paves the way for Artemis III, which intends to see astronauts set foot on the lunar surface once again. By verifying the safety and functionality of the SLS and Orion in a crewed environment, NASA has moved one step closer to establishing a sustainable human presence on the Moon and expanding the frontiers of human exploration.
