Mission Overview
NASA’s Artemis II mission is the second planned flight of the Artemis program, which aims to return humans to the Moon by 2024. Scheduled for launch in 2024, Artemis II will be the first crewed flight of the Orion spacecraft and the first crewed flight to the Moon since the Apollo 17 mission in 1972.
The primary objective of Artemis II is to test the Orion spacecraft and its life support systems in lunar orbit for an extended period. The mission will also demonstrate the ability to conduct spacewalks in lunar orbit and will collect scientific data on the Moon’s surface using the Lunar Gateway, a mini-space station that will serve as a waypoint for future lunar missions.
Crew
The Artemis II crew will consist of four astronauts: two mission commanders, a pilot, and a mission specialist. The crew members have been selected from NASA’s 2017 astronaut class and are currently undergoing training for the mission.
Spacecraft
The Orion spacecraft is a next-generation spacecraft designed to carry humans to the Moon and beyond. Orion is the largest spacecraft ever built by NASA and is capable of carrying up to six astronauts. The spacecraft is made up of three main modules:
- Crew module: This module provides living quarters for the astronauts during the mission.
- Service module: This module contains the spacecraft’s propulsion systems, power generation systems, and other critical systems.
- Launch abort system: This system is designed to pull the Orion spacecraft away from the launch vehicle in the event of an emergency.
Launch Vehicle
Artemis II will be launched by the Space Launch System (SLS), a heavy-lift rocket designed to carry the Orion spacecraft to the Moon. SLS is the most powerful rocket ever built and is capable of generating over 8 million pounds of thrust.
Mission Timeline
Artemis II is scheduled to launch in 2024 from Kennedy Space Center in Florida. The mission will last approximately 10 days. During the mission, the astronauts will spend several days in lunar orbit, conducting spacewalks and collecting scientific data. The astronauts will then return to Earth, splashing down in the Pacific Ocean.
Significance
Artemis II is a critical mission in NASA’s Artemis program. The mission will test the Orion spacecraft and its life support systems, demonstrate the ability to conduct spacewalks in lunar orbit, and collect scientific data on the Moon’s surface. This information will be essential for planning future crewed missions to the Moon and, eventually, Mars.
