Former NASA Astronaut, Jeffrey A. Hoffman, has said a mission to the moon would be far cheaper and safer than going to Mars, and that it would act as a good rehearsal before attempting to visit the red planet.
Yahoo News reports:
A mission to the moon would be infinitely cheaper, shorter, and safer than a trip to Mars, which is partly why Hoffman says it makes more sense to revisit our lunar neighbor before we attempt to conquer the Red Planet.
The moon is nearly 600 times closer than Mars, and we already have a history of successfully landing on it. During the Apollo missions, NASA sent 24 astronauts to the moon, 12 of whom walked on the surface.
Does this success make the moon any less interesting to explore? Of course not!
“We basically just scratched the surface during Apollo, you know,” Hoffman told Business Insider. “Some people say, ‘Oh, been there. Done that.’ They just don’t understand.”
And he’s not the only one who thinks this.
Retired Canadian astronaut Chris Hadfield agrees that the moon is a more sensible goal. NASA’s spacecraft Orion was built to shepherd astronauts to Mars by the 2030s, and “that is a great vehicle,” Hadfield told The Guardian. “But where we are going to go next is the moon.”
He continued: “That’s where we are going to go because it just makes sense. It is only three days away and we can invent so many things.”
Hoffman and Hadfield have a point — and it’s one quickly lost in the minds of Mars-dreamers like Mars One and SpaceX’s Elon Musk.
From a space-exploration point of view, one of the most important things to explore on the moon is its vast number of craters.
“If it turns out there are large water deposits in some of these craters in the moon, we could turn that into rocket fuel and transform the economics of space travel,” Hoffman said.
A study in 2012 suggested possible evidence for the existence of ice in the lunar crater Shackleton Crater, but more investigations are necessary to ultimately determine if this crater, as well as others on the moon, hold enough ice to fuel future rockets. A manned mission could readily collect samples to determine this.
If that isn’t incentive enough, Hoffman advises, consider just how long it has been since humankind has set foot on any natural body besides Earth. In fact, it has been more than 45 years since Neil Armstrong and Buzz Aldrin first set foot on the moon.
“If we’re going to go to Mars, I think getting a little practice under our belts would be a good idea,” Hoffman said.
Hoffman concluded, “Whether it’s absolutely necessary [to revisit the moon], I don’t know … but I think it makes sense to go to the moon and test out our systems and get people used to the idea of planetary exploration again.”
