Astronauts have traditionally been serious, sensible types with the "right stuff" who can (trust) to fly equipment. But any mission to Mars will need a "joker" or "class clown" figure to be (success), according to NASA research. A sense of humor will be vital for any team to keep morale (士气) high on a twoyear trip to Mars may happen in the 2030s.
According to researchers, groups work best when they have a "joker" who has the ability to pull everyone together, bridge gaps when tensions appear really boost morale. When astronauts are in a confined space on a mission to Mars, tensions are likely (occur). It's vital that there should be one who can help everyone get along, so they can do their jobs and get there and back (safe).
Researchers have studied isolated groups of people in extreme environments including Russian, Chinese, Indian and Polish (explorer) based in Antarctica. Norwegian explorer Roald Amundsen succeeded while Captain Scott (fail) to reach the South Pole because the Norwegians had a "clown" figure on their team. He laughed and was very happy, (keep) up people's spirits.
But researchers added: "Being funny won't be enough to land somebody the job. He also needs to be excellent scientist and engineer and be able to pass a strict training programme."
