This week's Question: In recent years, hundreds of millions of dollars have been invested into space ventures. SpaceX, an advanced spacecraft manufacturer founded by Elon Musk, has completed more than 30 successful launches since 2006, delivered cargo to the International Space Station, and secured contracts with NASA and other clients. Musk envisions the colonization of Mars as soon as 2022. In September, speaking to the International Astronautical Congress in Mexico, Musk described a 400-foot-tall rocket that would send 100 colonist-passengers at a time to Mars over a period of decades.
“One [path] is that we stay on Earth forever and then there will be an inevitable extinction event,” Musk said. “The alternative is to become a spacefaring civilization, and a multi-planetary species.”
What do you think? Will we be a “multi-planetary” species?
