Four military volunteer have now been shut out inside aMarshabitat simulation . Should everything go to plan , they will come forth from the experiment in a yr .
NASA ’s Crew Health and Performance Exploration Analog ( CHAPEA ) mission is the first of three be after pretense of go on the surface of Mars . The crew – include a microbiologist and a doctor – will take on astronaut roles of flight engineer , medical officer , scientific discipline policeman , and commander while they remain in their three-D - print , 158 - hearty - m ( 1,700 - square animal foot ) Mars Dune Alpha habitat .

As well as the psychological strain of being away from loved I for a year , the crew will face other challenges typeset by the researchers overseeing them . CHAPEA will copy conditions that gang of a Mars charge would face , including circumscribed resources andcommunication delayslasting between5 and 20 minute . They will also face simulate equipment failure and other " environmental stressors " , according toNASA . The crew will conduct action such as simulating walks outside the habitat on Mars , and other scientific research .
“ The parallel is critical for testing resolution to meet the complex needs of living on the Martian airfoil , ” Grace Douglas , lead scientist forNASA ’s Advanced Food Technology enquiry effort at NASA ’s Johnson Space Center in Houston , said in a 2021 press handout . “ Simulations on Earth will help us empathise and counter the forcible and mental challenges astronaut will face up before they go . ”
Previous attempt have been made to copy recollective - full term living on another satellite , with mixed results . Simulations run by Scientific International Research In Unique Terrestrial Station ( Project SIRIUS ) and Mars-500 find that the crew began to inhabit more autonomously as communicating delays increased . Though positive in the good sense that any Mars crew would demand to perform duty alone , there were worries of potential disconnects between astronaut on the surface and mission dominance back on Earth .
" The negative side is that the delegation dominance loses the theory to understand the needs and problems of the crew , " Dmitry Shved of the Russian Academy of Sciences and the Moscow Aviation Institute toldCNET , " which consequently hinders mission control ’s ability to provide support . "
In a far more disastrous simulation of life story inside a " self - contained"biosphere , participants look real - life problems of not having enough solid food , and oxygen supplying became low .
