![]() ![]() The orbit is “distant” in the sense that it’s at a high altitude from the surface of the Moon, and it’s “retrograde” because Orion will travel around the Moon opposite the direction the Moon travels around Earth. 25 with the second maneuver, called the distant retrograde orbit insertion burn. Orion will enter distant retrograde orbit beyond the Moon on Friday, Nov. 20, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. The spacecraft entered the lunar sphere of influence Sunday, Nov. The spacecraft was preparing for the Outbound Powered Flyby maneuver which would bring it within 80 miles of the lunar surface, the closest approach of the uncrewed Artemis I mission, before moving into a distant retrograde orbit around the Moon. 21, 2022) – The Earth is seen setting from the far side of the Moon just beyond the Orion spacecraft in this video taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. “The mission continues to proceed as we had planned, and the ground systems, our operations teams, and the Orion spacecraft continue to exceed expectations, and we continue to learn along the way about this new, deep-space spacecraft,” said Mike Sarafin, Artemis I mission manager, in a Nov. Orion later flew over the Apollo 14 site at about 6,000 miles in altitude and then over the Apollo 12 site at an altitude of about 7,700 miles ![]() Shortly after the outbound flyby burn, the space craft passed about 1,400 miles above the Apollo 11 landing site at Tranquility Base at 7:37 a.m. The spacecraft speed increased from 2,128 mph before the burn to 5,102 mph after the burn. Orion completed the outbound powered flyby at 6:44 a.m., passing about 81 miles above the surface at 6:57 a.m. The first three trajectory correction burns provided an opportunity to fire all three thruster types on Orion with the first using the large orbital maneuvering system engine, the second using the small reaction control system thrusters, and the third using the medium-sized auxiliary engines. CST ahead the first of two maneuvers required to enter a distant retrograde orbit around the Moon. On its sixth day into the Artemis I mission, Orion successfully completed its fourth orbital trajectory correction burn using the auxiliary engines at 1:44 a.m. The darkest spot visible near the middle of the image is Mare Orientale. ![]() 21, it came within 80 miles of the lunar surface, the closest approach of the uncrewed Artemis I mission, before moving into a distant retrograde orbit around the Moon. 21, 2022) A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken on the sixth day of the Artemis I mission by a camera on the tip of one of Orion’s solar arrays. ![]()
