Artemis II
Artemis program's second lunar flight
Artemis II is a planned lunar spaceflight mission under the Artemis program, led by NASA. It is intended to be the second flight of the Space Launch System (SLS), and the first crewed mission of the Orion spacecraft. It is the first crewed mission around the Moon, and beyond low Earth orbit, since A...

Why It Matters
This news is important because Artemis II represents the first crewed mission to orbit the Moon since Apollo 17 in 1972, marking a critical step toward returning humans to the lunar surface. The safety protocols directly affect the four astronauts aboard—Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen—whose lives depend on these systems during the 10-day mission. It also impacts NASA's credibility and future funding for deep space exploration, as any safety failure could jeopardize the entire Artemis program and international partnerships. The mission's success is crucial for establishing sustainable lunar presence and preparing for eventual Mars missions.
Context & Background
- Artemis II follows the uncrewed Artemis I mission that successfully tested the Space Launch System rocket and Orion spacecraft in 2022
- The Artemis program aims to land the first woman and first person of color on the Moon by 2025 with Artemis III
- NASA's last crewed lunar mission was Apollo 17 in December 1972, ending the Apollo program after six successful landings
- The Orion spacecraft incorporates safety improvements over Apollo-era technology, including enhanced radiation protection and modern abort systems
- Artemis involves international collaboration with the European Space Agency (providing Orion's service module) and the Canadian Space Agency (contributing robotic arms)
What Happens Next
Following Artemis II's planned November 2024 launch, NASA will analyze mission data to certify systems for Artemis III's lunar landing. The agency will begin selecting and training Artemis III surface crews in 2025 while developing lunar Gateway station components. SpaceX's Starship lunar lander development continues in parallel, with uncrewed test flights scheduled before the Artemis III mission.
Frequently Asked Questions
Artemis II will be the first crewed mission to use NASA's new Space Launch System rocket and Orion spacecraft, testing life support systems farther from Earth than any human-rated spacecraft has traveled before. Unlike Apollo missions that went directly to lunar orbit, Artemis II will perform a figure-eight trajectory around the Moon without landing, focusing on system validation for future surface missions.
Primary risks include radiation exposure beyond Earth's magnetic field, potential spacecraft system failures during critical maneuvers, and emergency scenarios requiring rapid return to Earth. NASA addresses these through redundant systems, enhanced radiation shielding in Orion's crew module, and multiple abort options throughout different mission phases.
Orion incorporates launch abort systems that can separate the crew module from the rocket within milliseconds of detecting problems—a capability the Space Shuttle lacked after Challenger. The capsule design also allows for water landings with parachutes, providing more controlled returns than the Shuttle's runway landings.
Astronauts receive extensive medical training and the spacecraft carries advanced medical kits, including telemedicine capabilities for Earth-based physician consultation. For life-threatening situations, mission protocols allow for early termination and return using Orion's propulsion systems, though this would depend on the mission phase and location.
NASA conducts extensive simulations using Orion mockups, virtual reality training, and underwater astronaut training in NASA's Neutral Buoyancy Laboratory. The Artemis I mission validated heat shield performance and re-entry systems, while parachute tests and abort motor tests have been conducted at various facilities including White Sands Missile Range.
