Elon Musk reflects on sun reflectors instead of forcing Mars to warm up

When SpaceX founder Elon Musk gets a Twitter role, it can be hard to keep up. In a moment he proposes to nuclearise Mars to accelerate the warming of the Red Planet for colonists, the next moment he thinks about solar reflector satellites.

While breathing on Mars is more conspicuous, behind the concept of the Mars orbital mirrors is a rather intriguing science.

Back in 2006, when Rigel Woida, a student at the University of Arizona, won a NASA award for the study of "using high-aperture, lightweight mirrors to" terraform "an area of ​​the Martian surface to allow people to see the Red It is a science-fiction dream to find a way to make Mars more habitable for human life.

Mars can become vicious cold and would require significant investment in creating safe habitats and spacesuits that can withstand extreme temperatures. Would not it be nice if we could just heat it up a bit?

Musk did not specifically mention Woida's research, but the work directly ties in with the reflector concept. Woida published a 2007 report (PDF link) describing how such a system works. The idea would be to launch a series of satellites that strategically reflect the sun's heat to the Martian surface.

"Could it make sense to have thousands of solar reflector satellites to warm Mars against artificial suns," Musk tweeted on Tuesday, suggesting that the best option was "still to be determined."

Musk also took one Momentum to clarify what he means by "Nuke Mars" refers to a continuous stream of nuclear fusion explosions with very little fallout across the atmosphere to create artificial suns. Like our Sun, this would not cause the Sun to fail Mars becomes radioactive. "

However, NASA is not so sure about this nuclear weapons plan. In mid-2018, the Space Agency declared Mars terraforming was not possible with today's technology .

Woida concludes in his work that the reflector concept is feasible and that "the technical requirements required to complete the project heating of a small part of Mars are achievable."

Musk and SpaceX get thanks to the Starlink Broadband System Abundant exercise with satellites on Earth. Perhaps Musk will channel some of SpaceX's resources towards the Mars mirror as the company's next generation Starship moves closer to launch . Musk hopes one day to be able to colonize the Red Planet.

It would be nice to have to pack sun hats and tank tops if people ever went to Mars.
