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 mission represents humanity's first crewed return to lunar space since 1972, marking a pivotal moment in space exploration. It directly affects NASA's international partners, commercial space companies, and scientific communities worldwide who are invested in lunar research. The success of Artemis II is crucial for validating spacecraft systems before attempting a lunar landing with Artemis III, potentially establishing sustainable human presence beyond Earth orbit. This mission also inspires STEM education and demonstrates international collaboration in space exploration.
Context & Background
- The last human mission to the Moon was Apollo 17 in December 1972, ending NASA's Apollo program after six successful landings
- Artemis I launched in November 2022 as an uncrewed test flight, successfully orbiting the Moon and returning to Earth
- 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 represent the agency's first deep space crew vehicles since the Space Shuttle era
What Happens Next
Following the Artemis II launch, the crew will conduct a 10-day mission orbiting the Moon before returning to Earth, with splashdown expected in the Pacific Ocean. If successful, NASA will proceed with Artemis III, currently scheduled for 2026, which aims to land astronauts near the lunar south pole. The mission will test critical systems including life support, radiation protection, and communication during the crew's journey approximately 6,400 miles beyond the Moon's far side.
Frequently Asked Questions
Artemis II will be the first crewed mission to travel to lunar space since 1972, testing new spacecraft systems including the Orion capsule and life support for deep space. Unlike Apollo missions that landed on the Moon, Artemis II will orbit without landing, serving as a crucial test before future surface missions.
The four-person crew includes NASA astronauts Reid Wiseman (commander), Victor Glover (pilot), Christina Koch (mission specialist), and Canadian Space Agency astronaut Jeremy Hansen (mission specialist). This represents the most diverse lunar crew in history, including the first woman and first person of color to travel to lunar space.
NASA aims to establish sustainable lunar exploration as a stepping stone for future Mars missions, leveraging new technologies and international partnerships. The Moon's south pole contains water ice and other resources that could support long-term human presence and serve as a testing ground for deep space systems.
Primary risks include radiation exposure beyond Earth's protective magnetosphere, spacecraft system failures during critical maneuvers, and emergency return scenarios. The mission will test new heat shield technology during high-speed reentry, which is crucial for crew safety.
Artemis II tests deep space habitation systems, radiation protection, and navigation techniques essential for the longer journey to Mars. The mission validates spacecraft performance in lunar orbit, which simulates some conditions of interplanetary travel beyond Earth's immediate vicinity.
