Artemis II: Orion Executes TLI Burn, Moon Expedition Begins on Day 2

NASA’s Artemis II mission has officially commenced its journey toward the Moon. Following a successful “Go” poll from the mission management team, the Orion spacecraft executed a translunar injection (TLI) burn on April 2, 2026, at 7:49 p.m. EDT. This maneuver lasted five minutes and 50 seconds, propelling the crew out of Earth’s orbit and onto a trajectory aimed at the lunar surface.
Details of the TLI Burn
Orion’s main engine delivered an impressive thrust of 6,000 pounds. This power allows acceleration comparable to a car going from 0 to 60 mph in just 2.7 seconds. The spacecraft weighed 58,000 pounds during the burn, depleting approximately 1,000 pounds of fuel.
Crew Health and Exercise Monitoring
The Artemis II crew, comprising NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen from the Canadian Space Agency, are maintaining their physical fitness aboard Orion. They utilize a flywheel exercise device that supports both aerobic and resistive workouts. This compact equipment, weighing only 30 pounds, serves as a vital alternative for exercise in deep space, where traditional exercise setups are impractical.
- Flywheel features:
- Weight: 30 pounds
- Size: Comparable to a carry-on suitcase
- Resistance capacity: Up to 400 pounds
Communication and Operations
During the mission, a brief communication disruption occurred, attributed to a ground configuration issue with the Tracking and Data Relay Satellite system. The problem was quickly resolved, ensuring mission operations continued smoothly.
Lunar Science Team’s Preparations
In the aftermath of the TLI burn, the lunar science team began developing a Lunar Targeting Plan. This plan will guide the crew in observing the Moon’s surface during their nearly six-hour flyby on April 6, 2026. Key focus areas will include:
- Craters
- Ancient lava flows
- Cracks and ridges from geological shifts
Notably, the crew will witness a solar eclipse toward the flyby’s end. As the Sun hides behind the Moon, they will observe the solar corona and may spot meteoroid impacts on the Moon’s surface.
