Nasa has outlined its four stage plan (pictured) which it hopes will one day allow humans to visit Mars at he Humans to Mars Summit held in Washington DC yesterday. This will entail multiple missions to the moon over coming decades.
Astronauts have traditionally been serious, sensible types with the 'right stuff' who can be trusted to fly equipment worth billions of pounds.
But any mission to Mars will need a 'joker' or 'class clown' figure to be successful, according to NASA research.
A sense of humor will be vital for any team to keep morale high on a two-year trip to Mars which could happen in the 2030s.
bwin必赢亚洲官网The joker role will be tested in NASA's group mission simulations at the Johnson Space Center in Houston, Texas.
bwin必赢亚洲官网Jeffrey Johnson, Professor of Anthropology at the University of Florida, Gainesville is advising NASA's Human Exploration Research Analog, a project which looks at how teams can cope with extreme periods of isolation.
bwin必赢亚洲官网He addressed the American Association for the Advancement of Science annual conference on 'Building a Winning Team for Missions to Mars'.
Professor Johnson said: 'Groups work best when they have somebody who takes on the role of class clown.
bwin必赢亚洲官网'These are people that have the ability to pull everyone together, bridge gaps when tensions appear and really boost morale.

bwin必赢亚洲官网'We can all think of the person at work who fulfills this role, who makes us laugh and makes the job more enjoyable. People like being around them.
'When you're living with others in a confined space for a long period of time, such as on a mission to Mars, tensions are likely to fray.
'It's vital you have somebody who can help everyone get along, so they can do their jobs and get there and back safely. It's mission critical.
bwin必赢亚洲官网Professor Johnson has studied isolated groups of people in extreme environments including Russian, Chinese, Indian and Polish explorers based in Antarctica.
