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 announcement matters because it represents the first crewed mission to the Moon in over 50 years, marking a major milestone in human space exploration. It affects NASA's international partnerships, commercial space industry development, and scientific research communities. The mission demonstrates renewed global commitment to lunar exploration and establishes a foundation for future Mars missions, inspiring STEM education worldwide.
Context & Background
- The last human Moon landing was Apollo 17 in December 1972, ending the Apollo program
- Artemis I was an uncrewed test flight that successfully orbited the Moon in late 2022
- The Artemis program aims to establish sustainable lunar exploration with international partners including ESA, JAXA, and CSA
- NASA's Space Launch System (SLS) rocket and Orion spacecraft form the core transportation system for Artemis missions
- The program includes plans for the Lunar Gateway station and eventual human missions to Mars
What Happens Next
Following crew selection, the Artemis II astronauts will begin intensive training for their 10-day mission scheduled for late 2024 or 2025. The mission will test Orion's life support systems during a lunar flyby without landing. Success will pave the way for Artemis III, planned for 2025-2026, which aims to land astronauts near the lunar south pole.
Frequently Asked Questions
Artemis II will test new spacecraft systems and orbit the Moon without landing, unlike Apollo missions that descended to the surface. The mission uses modern technology and international collaboration, preparing for sustainable lunar presence rather than brief visits.
The lunar south pole contains permanently shadowed craters with water ice deposits that could support life and rocket fuel production. This region also offers near-continuous sunlight for solar power, making it ideal for establishing sustainable lunar bases.
Artemis II tests deep space systems and human endurance needed for Mars missions. The experience gained will inform spacecraft design, radiation protection, and mission operations for the longer journey to Mars planned for the 2030s.
Primary risks include radiation exposure beyond Earth's magnetic field, spacecraft system failures in deep space, and emergency return scenarios. The mission will validate safety systems and procedures for future longer-duration lunar missions.
International partnerships distribute costs and expertise while establishing peaceful exploration norms. Partners contribute critical components like the European Service Module for Orion and Gateway station elements, creating global investment in sustainable lunar exploration.
