NASA plans to send two people to Mars for 30 days
Science and Technology Daily, Beijing, May 25 (Reporter Liu Xia) According to a report by the American Fun Science website on the 24th, the National Aeronautics and Space Administration (NASA) recently announced its initial plan for a 30-day two-person mission to the surface of Mars.NASA's goal is to send astronauts to the surface of Mars in the late 2030s or early 1940s and perform related science missions.
NASA said there are still many challenges ahead to realize this vision.Even if the funding and technology are in place on time, the round-trip time will be around 500 days, given the long distance between Earth and Mars.Also, gravity, or lack thereof, will be an issue.Astronauts will arrive at Mars in microgravity for months, and work in the microgravity of Mars (the gravity on Mars is only one-third that of Earth).One solution, NASA suggested, could be for astronauts to live in pressurized rovers during their missions.
"We want to maximize the technology so we can get astronauts in 30 days to better walk on Mars and maximize conduct scientific research.”
NASA noted that this plan is in its early stages and could change a lot.NASA envisions a habitat-like spacecraft that uses a hybrid rocket stage powered by chemical fuel and electricity to send four astronauts to Mars, two of which land on the surface.
Before the astronauts arrive on Mars, NASA will first perform an unmanned mission to send about 25 tons of supplies and hardware to Mars, including a Mars rover that can carry people and fill up with fuel, and wait for the astronauts to arrive. carry out related tasks.
