Missions to Mars were possible decades ago but reportedly killed astronauts, says former Space Station commander

A former astronaut who spent months 250 miles above Earth said humans could have traveled to Mars "decades," but the missions would certainly have ended in death. astronauts to Mars, said Chris Hadfield, commander of the retired International Space Station. But even with the means to travel, astronauts would probably be dead in transit because of the high-risk conditions of a long exit in space.

"The majority of astronauts we send to these missions would not do it," says Business Insider.

The trip to Mars, about 140 million miles from Earth, could take up to three years. Longer space flights expose astronauts to higher risks of explosion; fuel and food shortages; Today's spacecraft use chemical rockets to explode the Earth's atmosphere and space, a relatively inefficient space-relocation mode that exchanges supplies and capabilities to protect fuel stocks. Even emerging rockets like SpaceX's Big Falcon and NASA's Space Launch System are burning fuel to launch into space. Hadfield compared the method to "using a sailboat or paddleboat to try to travel around the world."

"I do not think it's a practical way to get around." To send people to Mars because they are dangerous and too long and this exposes us to a long-standing risk, "he said.

Extended space travel is possible, however: NASA astronaut Scott Kelly spent 340 consecutive days at the International Space Station from 2015 to 2016, the most long stay in the space of an American astronaut. A Martian tour would mark the furthest interplanetary distance traveled by humans, a record currently held by the 1970 Apollo 13 mission, which sank nearly 250,000 miles from Earth – about 1/560 from the road to Mars.

Limits of human life on Mars. In 1991, the astronauts embarked on a two-year terrestrial mission in Biosphere 2, a simulation of an ecological chamber and a space colony that generated the conditions of air, food, and water on the planet. planet to measure the human response. Project researchers postulated that life on Mars would require a bioregenerative system in which plants, animals, and microbes would replenish the conditions necessary for life in an open air enclosure

according to NASA. The agency said it planned to send man-made missions to Mars in the 2030s, after President Donald Trump signed Directive 1 on Space Policy in March December 2017, calling for an expansion of human exploration of the solar system. [ad_2]
