I'm writing a short story inspired by David Bowie's Space Oddity. In it, we follow the thoughts of a cosmonaut who lost contact to ground control. The last contact he had was weeks ago, and now he lost contact.
Is it possible to lose contact to ground control for a long/long-ish period of time?
Edit: Thank you for the answers. They helped a great deal. I should note that the short story is currently on its first draft, but that I'll absolutely rewrite and rework stuff based on this thread later. About the cosmonaut : his name is Yuri Astrov.
