Five days into the 25.5-day Artemis I mission, Orion continues on its trajectory toward the Moon.
Flight controllers in the White Flight Control Room at NASA’s Johnson Space Center in Houston captured additional imagery of the Moon using the optical navigation camera.
Gathering imagery of the Earth and the Moon at different phases and distances will provide an enhanced body of data to certify its effectiveness as a location determination aid for future missions under changing lighting conditions, reported NASA.
Orion completed its third outbound trajectory correction burn at 6:12 a.m. CST, firing the auxiliary thruster engines for a duration of 6 seconds at a rate of 3.39 feet per second to accelerate Orion and adjust the spacecraft’s path while en route to the Moon. The amount of speed change determines which of Orion’s service module engines, reaction control, auxiliary, or orbital maneuvering system, to use for a particular maneuver.
The spacecraft entered into the lunar sphere of influence at 1:09 p.m. CST, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. Overnight, Orion will conduct the fourth outbound trajectory correction burn in advance of the outbound powered flyby burn.
Flight controllers will conduct the outbound powered flyby burn by firing the orbital maneuvering system engine for 2 minutes and 30 seconds to accelerate the spacecraft, harness the force from the Moon’s gravity, and direct it toward a distant retrograde orbit beyond the Moon.
The outbound powered flyby burn is the first of a pair of maneuvers required to enter a distant retrograde orbit around the Moon. NASA will cover the maneuver live starting at 7:15 a.m. EST on the agency’s website, NASA Television and the NASA apps.
Engineers expect to lose communication with the spacecraft as it passes behind the Moon for approximately 34 minutes starting at 7:26 a.m. The Goldstone ground station, part of NASA’s Deep Space Network, will acquire the spacecraft once it emerges from behind the Moon.
Mission managers currently have two active anomaly resolution teams. Anomaly resolution teams are a standard part of managing the mission by pulling together a team of technical experts to focus on a specific issue by examining data to understand the implications in a particular system.
Activating a separate team for this work enables engineers and flight controllers to continue focusing on commanding and monitoring the spacecraft and assessing the progress of the flight test, as reported by NASA
