The two things produces by plants that would be important to keep astronauts alive on a long journey would be glucose and oxygen. Oxygen is most important.

During regular intravehicle activity (such as coasting to the moon) the crew wore Constant Wear Garments, or CWGs. These were basically long underwear with some pockets.
The Lunar rover is not a robot as such like the Mars rovers. It was a sort of electric dune buggy controlled by the astronauts. It had both radio and television capacity. Oh, the camera mounted on it had a remote control that a man in Mission Control could operate. He was able to televise the liftoff of the astronauts by knowing just when it would take off, where it would go, and how long it would take for the camera to obey his orders.
Including USSR -Cosmonauts - Astronauts have been around since the 1960's.

The Challenger astronauts survived for approximately 2 minutes and 45 seconds after the shuttle broke apart in mid-air on January 28, 1986. The crew did not survive the impact with the ocean.
It would take too long to get there. We don't have the capacity to send an unsupported crew into space for more than about a month. We would have to pack two years of food for the astronauts and we cant store that much. There is also the issue of carrying the fuel to get home.
The number of astronauts that can fit in a spaceship varies depending on the design and purpose of the spacecraft. For example, NASA's Space Shuttle could carry up to seven astronauts, while the International Space Station (ISS) can accommodate six crew members for long-duration missions. More recent spacecraft, like SpaceX's Crew Dragon, are designed to carry up to seven astronauts as well. Ultimately, the capacity is determined by factors such as life support systems, mission objectives, and available space.

in order to get more oxygen
It depends an the vessel, crew, weather etc
The typical stay for astronauts on the International Space Station (ISS) is about six months. However, some missions can last longer or shorter depending on the specific objectives and crew rotations.
they stay as astronauts for 6 or more months
