Artemis 2 Crew’s 10-Day Journey Around Earth and the Moon – A Timeline of NASA’s Historic Moon Mission
NASA’s Artemis 2 mission ended with a precise splashdown in the Pacific Ocean, capping a nearly 10-day journey that took the four astronauts far from Earth. The Orion space capsule “Integrity” landed in calm waters off California, with all crew members confirmed safe.The mission, which flew a total of 694,392 miles (more than 1.1 million kilometers), marked the first manned voyage near the moon since the Apollo era and was a key step toward future lunar landings.
Here is the schedule for the Artemis 2 mission:
April 1-2: Launch, orbit and critical system verification
The mission lifted off from the Kennedy Space Center on April 1 aboard NASA’s Space Launch System. After separation, Orion entered Earth orbit and astronauts conducted extensive inspections of life support systems, propulsion systems, avionics and solar panels.This stage is equivalent to a “stabilization cruise” to ensure that the spacecraft can safely support human life before embarking on deep space travel. Engineers also verified the launch abort system and onboard batteries, which are critical in the event of an emergency.
April 2-5: Translunar Injection and Deep Space Transportation
On April 2, Orion performed a powerful translunar jet burn, accelerating to nearly 22,000 mph and setting a course for the moon. Over the next three days, the astronauts traveled approximately 240,000 miles, through the Van Allen radiation belts and into deep space.Astronauts conduct experiments on the effects of microgravity while also monitoring navigation systems, radiation shielding and spacecraft autonomy. The spacecraft operates primarily on automated systems, requiring minimal human intervention.
April 5-6: Closest and record-breaking lunar flybys
Artemis 2 arrived at the moon around April 5, performing a close flyby that brought it just a few thousand miles from the lunar surface. The crew took high-resolution images and studied the moon’s terrain, including target areas for future missions.Orion begins its return journey by using the moon’s gravity in a slingshot motion. At this stage, the mission set a new record distance of 252,756 miles from Earth, surpassing Apollo 13’s record.The flyby also marked a historic milestone, with the crew including the first woman, first black astronaut and first non-American on a mission to the moon.
April 6-10: Return and re-entry preparations
The return trip lasted another three to four days, during which the crew conducted final system checks and scientific observations. Engineers closely monitor the spacecraft’s heat shield performance data in preparation for re-entry, considered the most dangerous phase of the mission.Drawing on lessons learned from the Artemis 1 test flight, Orion’s orbit was carefully adjusted to reduce heat stress.
April 11: High-risk reentry and ‘perfect bullseye’ splashdown
On April 11, Orion re-entered the Earth’s atmosphere at a speed of up to 32 times the speed of sound. According to Reuters, the capsule experienced severe friction, with temperatures reaching nearly 5,000°F, and communications were briefly lost for more than six minutes due to ionized plasma.Contact was restored before the parachute deployed, slowing the capsule to about 25 km/h before precise splashdown. A NASA commentator described it as a “perfect bullseye splashdown.”NASA and U.S. Navy rescue teams secured the capsule within two hours. The astronauts were flown by helicopter to the USS John P. Moussa for medical clearance before returning to Houston.The mission’s success validates key technologies needed for future Artemis missions, including planned crewed lunar landings, and reinforces NASA’s broader goal of sending humans to Mars.
