NASA’s Artemis II Mission Successfully Leaves Earth’s Orbit for Flight Around the Moon
In a groundbreaking achievement, astronauts on a NASA mission have embarked on a journey to fly around the Moon for the first time in over 50 years. This milestone was reached after the successful completion of a crucial burn of Orion’s main engine, marking a significant step forward in space exploration.
During the approximately six-minute firing of the spacecraft’s service module engine, known as the translunar injection burn, the crew of NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen accelerated to break free of Earth’s orbit. This maneuver set Orion on a trajectory towards Earth’s nearest neighbor, the Moon.
Dr. Lori Glaze, acting associate administrator for the Exploration Systems Development Mission Directorate at NASA Headquarters, expressed excitement about this historic moment. She highlighted the significance of humans departing Earth’s orbit for the first time since Apollo 17 in 1972. The crew’s journey towards the Moon in Orion, operating with crew for the first time in space, represents a crucial step forward in NASA’s Artemis program.
The mission began with the launch of NASA’s Space Launch System (SLS) rocket and Orion spacecraft from Launch Pad 39B at the Kennedy Space Center in Florida. Lift-off occurred at 6:35 p.m. EDT on April 1, sending the four astronauts on a planned 10-day test flight around the Moon and back.
After reaching space, Orion deployed its solar array wings to harness energy from the Sun. Meanwhile, the crew and engineers on the ground transitioned the spacecraft from launch to flight operations, conducting system checkouts to ensure everything was functioning as expected.
Approximately 49 minutes into the test flight, the SLS rocket’s upper stage fired to place Orion into an elliptical orbit around Earth. A second burn by the stage propelled Orion, dubbed “Integrity” by the crew, into a high Earth orbit extending about 46,000 miles above the Earth. During this phase, the crew performed system checks for about 24 hours before Orion separated from the stage to fly free on its own.
The crew then conducted a manual piloting demonstration to test Orion’s handling qualities using the Interim Cryogenic Propulsion Stage (ICPS) as a docking target. Following the demonstration, Orion executed an automated departure burn to move away from the ICPS safely. The stage then performed a disposal burn, re-entering Earth’s atmosphere over a remote region of the Pacific Ocean.
Before re-entry, four small CubeSats were deployed from the SLS rocket’s Orion stage adapter. Other tasks completed included transitioning to the Deep Space Network for communications, acclimating to the space environment, rest periods, flywheel exercise, restoring the spacecraft’s toilet, and configuring for the translunar injection burn.
Next on the agenda is a planned lunar flyby on April 6, during which the astronauts will capture high-resolution photographs and make observations of the lunar surface. This includes areas of the far side of the Moon never directly seen by humans. The conditions during the flyby are expected to create shadows that enhance relief, revealing details often difficult to detect under full illumination.
Following the successful lunar flyby, the astronauts will return to Earth and splash down in the Pacific Ocean off the coast of San Diego. This mission is part of NASA’s larger goal to send Artemis astronauts on increasingly challenging missions to explore more of the Moon for scientific discovery, economic benefits, and to pave the way for future crewed missions to Mars.
