Space exploration is entering an exciting new chapter as humanity prepares to travel back to the Moon. The Artemis II mission is a major milestone in this journey, marking the first time astronauts will fly around the Moon in more than five decades. After the historic Apollo missions of the 1960s and 1970s, this mission signals the start of a new era of lunar exploration and scientific discovery. The mission is part of NASA’s ambitious Artemis programme, designed to return humans to the Moon, build a sustainable presence there, and eventually support future missions to Mars. The four astronauts aboard the Orion spacecraft will travel hundreds of thousands of miles in deep space, testing systems that will be essential for upcoming lunar landings.
What is Artemis II?
Artemis II is NASA’s first crewed mission under the Artemis programme. Unlike earlier test flights, this mission carries astronauts who will travel around the Moon before returning to Earth. The mission aims to test life-support systems, navigation technology, and spacecraft performance in deep space.
Meet the Astronauts:
The Artemis II crew consisted of the following four astronauts:
Reid Wiseman
- Age: 50
- Role: Commander
- Astronaut experience: 17 years
- Time spent in space: 6 months, flew to the International Space Station (2014)
- Previously served as NASA’s Chief of the Astronaut Office and is a Captain in the U.S. Navy.
Victor Glover
- Age: 49
- Role: Pilot
- Astronaut experience: 13 years
- Time spent in space: 6 months, piloted the SpaceX Crew-1 mission to the ISS (2020-2021)
- A Navy Captain and test pilot who has flown over 40 different types of aircraft.
Christina Koch
- Age: 47
- Role: Mission specialist
- Astronaut experience: 13 years
- Time spent in space: 11 months on the International Space Station (2019–2020)
- Holds the record for the longest single spaceflight by a woman (2019–2020) and took part in the first three all-female spacewalks.
Jeremy Hansen
- Age: 50
- Role: Mission Specialist
- Astronaut experience: 17 years
- Time spent in space: First spaceflight on Artemis II
- A Royal Canadian Air Force Colonel and fighter pilot, and the first Canadian astronaut selected for a mission around the Moon.
The Artemis II Mission Timeline
Day 1: Launch
The mission begins with a powerful launch from Kennedy Space Center in Florida aboard NASA’s Space Launch System (SLS) rocket. Once in orbit around Earth, the crew checks the Orion spacecraft systems to ensure everything is working perfectly.
Day 2: Leaving Earth Orbit
The spacecraft performs a Translunar Injection burn, a powerful engine firing that sends Orion out of Earth’s orbit and onto its journey toward the Moon.
Day 3: Systems Check in Deep Space
As the spacecraft travels through deep space, astronauts perform health checks and test life-support and communication systems.
Day 4: Navigation and Course Correction
The crew fine-tunes the spacecraft’s path and practises manual piloting procedures to ensure accurate navigation.
Day 5: Entering the Moon’s Gravitational Influence
Orion approaches the Moon and enters its gravitational field. The crew prepares for the closest pass around the lunar surface.
Day 6: Historic Lunar Flyby
The spacecraft flies about 4,067 miles above the Moon, allowing astronauts to capture stunning images and collect valuable data. During this journey, the crew reaches a record distance from Earth for humans.
Day 7: Turning Back Toward Earth
After passing around the far side of the Moon, Orion begins its journey back toward Earth.
Day 8: Safety and Survival Drills
Astronauts practise emergency procedures such as building a radiation shelter inside the spacecraft.
Day 9: Preparing for Reentry
The crew secures equipment and performs a final trajectory correction to ensure a safe path back to Earth.
Day 10: Reentry and Splashdown
As Orion reenters Earth’s atmosphere, it travels at nearly 25,000 miles per hour, heating the spacecraft to around 5,000°F. A powerful heat shield protects the crew before parachutes deploy and the capsule splashes down safely in the Pacific Ocean.
Mission Statistics
- Total distance travelled: 695,081 miles
- Maximum speed: About 25,000 miles per hour during reentry
The Artemis II mission is more than just a trip around the Moon. It is an important step toward building a long-term human presence beyond Earth. The data collected during this mission will help scientists prepare for future lunar landings and establish new technologies for deep-space travel.
If successful, Artemis II will open the door to Artemis III, the mission expected to land astronauts on the Moon’s surface and mark humanity’s true return to lunar exploration.
