My job was complete
After the astronauts finished their lunar surface activities, the ascent stage separated from the descent stage and ignited its own engine.
What does jettison mean?
Jettison means deliberately releasing or discarding a spacecraft component when it is no longer needed. After reaching lunar orbit, the ascent stage docked with Columbia, piloted by Michael Collins. Armstrong and Aldrin transferred to the Command Module. At 00:01:01 UTC on 22 July, the Lunar Module was jettisoned into lunar orbit.
What happened to Eagle?
The descent stage remained at the landing site. The fate of the jettisoned Apollo 11 Lunar Module is not known with certainty. The NSSDCA account says it is assumed to have impacted the Moon within the following one to four months.
Mission details are based on the NASA/NSSDCA Apollo 11 Lunar Module / EASEP record supplied for this project.
