2021 marks 60 years since NASA's Project Mercury got underway. A series of single-person spaceflights - the first of their kind for the agency - it aimed to prove whether the most basic human functions were possible in space. Could a human eat and drink in zero gravity? Could they sleep? Could they even survive?
Sandwiched between two milestone American spaceflights, Gemini 5 is often overlooked. Gordo Cooper and Pete Conrad's flight was just as important though, even if Conrad described it as 'eight days in a garbage can'.
