In a first-of-its-kind experiment, NASA’s Perseverance rover has produced sufficient oxygen on Mars to maintain an astronaut alive for 3 hours.
The rover, which first touched down on Mars in February 2021, produced the ingredient utilizing its Mars Oxygen In-Situ Useful resource Utilization Experiment (MOXIE) gadget — which generated the oxygen by changing carbon dioxide in periodic bouts over two years.
Since arriving on the Purple Planet, the microwave-size gadget has generated 4.three ounces (122 grams) of oxygen, in accordance with NASA. That is the equal to what a small canine breathes in 10 hours and provides scientists hope that human life might, someday, be sustained on the inhospitable planet.
“We’re proud to have supported a breakthrough expertise like MOXIE that would flip native sources into helpful merchandise for future exploration missions,” Trudy Kortes, director of expertise demonstrations, House Expertise Mission Directorate (STMD) at NASA Headquarters in Washington, stated in an announcement. “By proving this expertise in real-world circumstances, we have come one step nearer to a future by which astronauts ‘reside off the land’ on the Purple Planet.”
Carbon dioxide is considerable on Mars, making up 95% of its skinny environment, in accordance with NASA. By zapping small quantities of carbon dioxide over 16 experiments, the MOXIE gadget stripped oxygen atoms from CO2 and analyzed them for purity earlier than sequestering them safely inside a capsule. The leftovers have been then emitted within the type of carbon monoxide.
The scientists say that oxygen extraction gadgets will not simply be helpful for future colonists to breathe however for making rocket gas too.
“MOXIE’s spectacular efficiency reveals that it’s possible to extract oxygen from Mars’ environment — oxygen that would assist provide breathable air or rocket propellant to future astronauts,” Pamela Melroy, NASA’s deputy administrator, stated within the assertion. “Growing applied sciences that allow us use sources on the Moon and Mars is crucial to construct a long-term lunar presence, create a strong lunar financial system, and permit us to assist an preliminary human exploration marketing campaign to Mars.”
Regardless of this small however vital step, many profound well being challenges nonetheless stand in the way in which of a viable Mars colony. For starters, Mars is so chilly that its common temperature of round minus 80 levels Fahrenheit (minus 62 levels Celsius) would freeze a human to loss of life and not using a house swimsuit, and its low atmospheric strain would concurrently boil their blood. That is with out considering the bombardment of cancer-causing radiation from the dearth of a protecting ozone layer and the excessive losses to bone-density introduced on by the journey there.
Till these issues are overcome, humanity’s closest view of the Purple Planet continues to be from rovers equivalent to Perseverance. As a key a part of NASA’s $2.7 billion Mars 2020 mission, the robotic, alongside the Curiosity rover, is looking for indicators of historic life on Mars‘ floor by accumulating dozens of rock samples for eventual return to Earth. The rover is accompanied by the Ingenuity helicopter, which has thus far made 57 flights over the Martian floor.
