Sure Lunacy. If you want to build a city, try the MOON first. Then if you have a problem, we can rescue them in 3 days, instead of 3 years!!! Fix all the problems with habitats on the Moon (growing things, radiation, water, waste etc) and then graduate out to other planets. Hell, you could even beam them cable and Netflix on the moon!

Of course we all know what's on the moon :-)

There’s a long-standing joke that NASA is always 20 years from putting astronauts on Mars. Mission details shared at a recent summit shows that the space agency is right on schedule. A to-do list from 2015 looks remarkably similar to one compiled in 1990. One difference: NASA is now building a rocket and test-driving technologies needed to get a crew to Mars. But the specifics for the longest road trip in history — and what astronauts will do once they arrive — remain an open question.

“Are we going to just send them there to explore and do things that we could do robotically though slower, or can we raise the bar?” asked planetary scientist Jim Bell during the Humans to Mars summit. “We need to make sure that what these folks are being asked to do is worthy of the risk to their lives,” said Bell, of Arizona State University in Tempe.

The three-day symposium, which ended May 19, was organized by Explore Mars Inc., a nonprofit dedicated to putting astronauts on Mars by the 2030s.

While the summit didn’t break new scientific ground, it did bring together planetary scientists , space enthusiasts and representatives from both NASA and the aerospace industry to talk about the challenges facing a crewed mission to Mars and rough ideas for how to get there.

Part of the appeal in sending humans is the pace of discovery. Drilling just one hole with the Curiosity rover, which has been exploring Gale Crater on Mars since August 2012 (SN: 5/2/2015, p. 24), currently takes about a week. “It’s a laborious, frustrating, wonderful — frustrating — multiday process,” said Bell.

Humans also can react to novel situations, make quick decisions and see things in a way robotic eyes cannot. “A robot explorer is nowhere near as good as what a human geologist can do,” says Ramses Ramirez, a planetary scientist at Cornell University. “There’s just a lot more freedom.”

Researchers saw the human advantage firsthand in 1997 when they sent a rover called Nomad on a 45-day trek across the Atacama Desert in Chile. Nomad was controlled by operators in the United States to simulate operating a robot on another planet. Humans at the rover site provided a reality check on the data Nomad sent back. “There was a qualitative difference,” says Edwin Kite, a planetary scientist at the University of Chicago. And it wasn’t just that the geologists could do things faster. “The robots were driving past evidence of life that humans were finding very obvious.”

To get astronauts ready to explore Mars, the Apollo program is a good template, said Jim Head, a geologist at Brown University who helped train the Apollo astronauts. “Our strategy was called t-cubed: train them, trust them and turn them loose.” While each of the moon expeditions had a plan, the astronauts were trusted to use their judgment. Apollo 15 astronaut David Scott, for example, came across a chunk of deep lunar crust that researchers hoped to find although it wasn’t at a planned stop. “He spotted it three meters away,” said Head. “He saw it shining and recognized it immediately. That’s exploration.”

Despite a lack of clear goals for a jaunt to Mars, NASA is forging ahead. The Orion crew capsule has already been to space once; a 2014 launch atop a Delta IV Heavy rocket sent an uncrewed Orion 5,800 kilometers into space before it splashed down in the Pacific Ocean (SN Online: 12/5/2014). And construction of the Space Launch System, a rocket intended to hurl humans at the moon and Mars, is under way. The first test flight, scheduled for October 2018, will send Orion on a multiday uncrewed trip around the moon. NASA hopes to put astronauts onboard for a lunar orbit in 2021.

Meanwhile, the crew aboard the International Space Station is testing technologies that will keep humans healthy and happy during an interplanetary cruise. Astronaut Scott Kelly recently completed a nearly yearlong visit to the station intended to reveal the effects of long-duration space travel on the human body (SN Online: 2/29/2016). And on April 10, a prototype inflatable habitat — the Bigelow Expandable Activity Module — arrived at the station and was attached to a docking port six days later. The station crew will inflate the module for the first time on May 26. No one will live in it, but over the next two years, astronauts will collect data on how well the habitat handles radiation.
