How does the concept of time change from the beginning of the selection to the end of the selection? Time at the beginning of the selection passes quickly, filled with duties,schedules, and activities; by the end of the selection , time passes slowly while the astronauts are focused on their sadness and loneliness. Time at the beginning of the selection moves slowly as there is much for the astronauts to take in and appreciate; by the end of the selection, time goes by quickly as they wrap up their responsibilities and assignments. Time at the beginning of the selection appears to be a valuable reminder of the importance of having a routine to encourage a sense of security; by the end of the selection, time is a painful reminder of how much is being missed. Time at the beginning of the selection appears to be repetitive and never-ending for the astronauts.by the end of the selection, time has become a precious, limited opportunity to create life's memories.
