No. There's been a lot of work on the topic. Including simulated Mars mission where people are isolated for the same length of time, in the same amount of space. For examples: - MARS-500 at https://en.wikipedia.org/wiki/MARS-500 https://en.wikipedia.org/wiki/MARS-500 . - a NASA one which starts this fall - https://www.nasa.gov/feature/nasa-is-recruiting-for-yearlong-simulated-mars-mission/ https://www.nasa.gov/feature/nasa-is-recruiting-for-yearlong... . - HI-SEAS at https://en.wikipedia.org/wiki/HI-SEAS https://en.wikipedia.org/wiki/HI-SEAS and see also "When a Mars Simulation Goes Wrong" at https://www.theatlantic.com/science/archive/2018/06/mars-simulation-hi-seas-nasa-hawaii/553532/ https://www.theatlantic.com/science/archive/2018/06/mars-sim... Oh! And that Wikipedia page points to a list of such programs: https://en.wikipedia.org/wiki/List_of_Mars_analogs https://en.wikipedia.org/wiki/List_of_Mars_analogs Plus experience from people overwintering in the polar regions, living solo on islands, etc. It's not easy, but it's clearly doable for at least some humans.
