In a first - of - its - kind experiment , NASA ’s Perseverance rover has produced enough O on Mars to keep an astronaut live for three hours .
The rover , whichfirst touch down on Mars in February 2021 , produced the element using its Mars Oxygen In - Situ Resource Utilization Experiment ( MOXIE ) gadget — which generated the oxygen by convert carbon dioxide in occasional bouts over two age .

Since arrive on the Red Planet , the microwave - size gimmick has generated 4.3 ounces ( 122 grams ) of oxygen , concord to NASA . This is equivalent to what a small dog breathes in 10 time of day and gives scientists go for that human lifespan could , one day , be sustained on the inhospitable planet .
concern : Just 22 people are needed to colonize Mars — as long as they are the right personality character , study claim
" We ’re lofty to have supported a find technology like MOXIE that could release local resource into useful product for next exploration missions,“Trudy Kortes , director of engineering science demonstrations , Space Technology Mission Directorate ( STMD ) at NASA Headquarters in Washington , pronounce in a statement . " By prove this technology in real - world atmospheric condition , we ’ve get one whole step nigher to a time to come in which astronauts ' live off the land ' on the Red Planet . "
atomic number 6 dioxide is abundant onMars , making up 95 % of its slender atmosphere , according to NASA . By zapping small amount of carbon dioxide over 16 experiments , the MOXIE gimmick stripped oxygen atoms from CO2 and analyzed them for innocence before sequestering them safely within a abridgement . The leftovers were then emitted in the form of carbon monoxide .
The scientist say that oxygen extraction devices wo n’t just be utile for future colonist to respire but for making rocket fuel too .
" MOXIE ’s telling operation show that it is workable to excerpt oxygen from Mars ' ambience — oxygen that could help supply breathable air or rocket propellant to succeeding astronauts,“Pamela Melroy , NASA ’s deputy executive , say in the affirmation . " grow technologies that permit us apply resources on the Moon and Mars is critical to build up a foresighted - terminus lunar presence , create a robust lunar economy , and allow us to sustain an initial human geographic expedition political campaign to Mars . "
— NASA may have unknowingly base and kill foreign lifespan on Mars 50 years ago , scientist claim
— ' Building stop of life ' unwrap on Mars in 10 different rock sample distribution
— Mars may be slowly ripping its large moon apart
Despite this small but meaning footprint , many profound health challenge still put up in the way of a workable Mars colony . For starters , Mars is so cold that its average temperature of around minus 80 degree Fahrenheit ( minus 62 level Celsius ) would freeze down a human to end without a infinite suit of clothes , and its low atmospheric pressure would at the same time seethe their blood . This is without taking into accounting the onslaught of Crab - do radiotherapy from the deficiency of a protective ozone bed and theextreme losses to bone - densitybrought on by the journeying there .
Until these problems are overcome , manhood ’s snug view of the Red Planet is still from rover such as Perseverance . As a primal part of NASA ’s $ 2.7 billion Mars 2020 mission , the robot , alongside the Curiosity roamer , is searching for signs of ancientlife on Mars ' surface by collecting loads of rock samples for eventual takings to Earth . The bird of passage is accompanied by the cleverness helicopter , which has so far made57 flightsover the Martian surface .
