Reentry refers to the process of returning to a previous state or environment after being away. In the context of space exploration, it specifically describes the return of a spacecraft, such as the Space Shuttle, from outer space back to Earth. This involves navigating through the atmosphere and safely landing, often requiring precise calculations and engineering to manage heat and speed. In a broader social context, reentry can also refer to individuals, particularly those who have been incarcerated, returning to their communities after serving time. This process often involves challenges such as finding employment, housing, and reintegrating into society while addressing any stigma associated with their past.
