Are People the Biggest Challenge to Interstellar Travel?
The biggest challenge in mounting a space mission to another star may not be technology, but people, experts say.
Scientists, engineers, philosophers, psychologists andleaders in many other fields gathered in Houston last week for the 100 Year Starship Symposium, a meeting to discuss launching an interstellar voyage within 100 years.
“It seems like it would be so hard, and the biggest obstacle is ourselves. Once we get out of our way, once we commit to this, then it’s a done deal,” said former “Star Trek: The Next Generation” actor LeVar Burton, who is serving on the advisory committee of the 100 Year Starship project.
The initiative hopes to spur the development of new propulsion technologies, life support systems, starship and habitat designs, as well as myriad other necessaryinnovations, to send a vehicle beyond our solar system — where no manmade object has yet traveled — and to another star. As the closest stars to the sun are still light-years away, such a feat will be daunting. [How Interstellar Space Travel Works (Infographic)]
But Burton wasn’t the only one who said the most difficult part of interstellar spaceflight may be corralling public and governmental support, and getting the right thinkers to work together to attack the problem.
“I think the greatest challenges are going to be what the greatest challenges in anything are, and that’s the people piece,” said former NASA astronaut Mae Jemison, who was the first African-American woman to travel to space. Jemison is heading the new 100 Year Starship organization, which was founded with seedmoney from the Defense Advanced Research Projects Agency (DARPA).
“The really exciting thing and the scary thing is I know I can’t do it by myself, but there are a lot of people who want to help,” Jemison added.
Interstellar spaceflight for humanity isn’t inevitable, she said — merely imperative.
“We could screw it up,” Jemison told Space.com. “We could decide not to do it. But I can tell you what, if we don’t figure out how to do it, then we probably aren’t going to be around to worry about whether the sun turns into a red gas giant. Unless we find some focal aspiration that pushes us further, that helps us see ourselves as a species that we should be cooperating with, we’re going to be in trouble.”
Plus, if human beings can solve the challenges of interstellar spaceflight, in the process they will have solved many of the problems plaguing Earth today, experts said. For example, building a starship will require figuring out how to conserve and recycle resources, how to structure societies for the common well-being, and how to harness and use energy sustainably.
Perhaps the 100 Year Starship Symposium should partner up with the Build The Enterprise Project? They have a 100 year timeline also and I couldn’t think of a better marriage.
