Lunar Bound: Artemis II Leaves Earth’s Orbit for Historic Deep-Space Journey

Published: 3 April 2026 . The English Chronicle Desk. The English Chronicle Online—Your eyes on the stars as humanity returns to the lunar frontier.

Fifty-four years after the final Apollo mission, the “tether to Earth” has once again been severed. NASA’s Artemis II mission successfully executed its Trans-Lunar Injection (TLI) burn late Thursday, 2 April, propelling the Orion spacecraft—named Integrity—out of high Earth orbit and onto a trajectory toward the far side of the Moon. The four-person crew is now in the midst of a four-day transit across the cosmic void, marking the first time a crewed vehicle has ventured into deep space since 1972.

After spending roughly 24 hours in a highly elliptical Earth orbit to test life-support and manual piloting systems, mission control in Houston gave the “go” for the mission’s most critical maneuver.

• The Burn: At 7:49 PM EDT on Thursday, Orion’s service module ignited its main engine for five minutes and 50 seconds. The burn added thousands of kilometers per hour to the spacecraft’s velocity, successfully escaping Earth’s gravitational “well.”

• Crew Reaction: “Humanity has once again shown what we are capable of,” radioed Canadian Mission Specialist Jeremy Hansen shortly after the burn. “It’s your hopes for the future that carry us now on this journey around the Moon.”

• The Crew: Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen are reported to be in excellent spirits, with Koch jokingly referring to herself as the “space plumber” after successfully troubleshooting a minor issue with the spacecraft’s waste management system earlier in the flight.

Artemis II is not designed to enter lunar orbit or land. Instead, it utilizes a “free-return trajectory”—a figure-eight loop that uses the Moon’s gravity to “slingshot” the crew back to Earth without requiring a secondary major engine burn.

1. The Far Side Record: On Monday, 6 April, Orion is expected to reach its farthest point from Earth: approximately 252,799 miles (406,841 km). This will surpass the record for the farthest distance from Earth ever traveled by a crewed spacecraft, currently held by the Apollo 13 mission.

2. Unprecedented Views: The crew will pass approximately 4,600 miles (7,400 km) above the lunar surface. Because of the timing of the mission, they are expected to see sunlit portions of the lunar far side that were shrouded in darkness during the Apollo era.

3. The Solar Corona: In a rare celestial coincidence, the crew will also be positioned to witness a lunar eclipse from space, providing a unique vantage point to observe the Sun’s outermost atmosphere, the corona.

While Artemis II is a “flyby” mission, its success is the final gatekeeper for Artemis III, currently slated for 2027/2028, which aims to land the first woman and first person of color on the lunar South Pole. The current 10-day test flight is rigorously validating Orion’s communication with the Deep Space Network and its ability to protect the crew from deep-space radiation once beyond Earth’s magnetic field.

As the Earth continues to shrink in the Orion hatch window, the mission stands as a powerful symbol of international cooperation and a “lunar homecoming” for a new generation. If the trajectory remains true, the crew will splash down in the Pacific Ocean on Friday, 10 April, bringing with them the first human-captured data from the lunar vicinity in over half a century.
