What’s the Latest Development?
In the next four to six months, NASA must decide whether it will plan a flagship mission to Mars for the 2018 launch window, begging the question what such a mission would look like. As the new rover Curiosity executes daily missions on the surface of the Red Planet, NASA planners believe that sending a mission to collect and return Martian rock to Earth is the best step forward, both scientifically and in terms of eventually sending humans to Mars: “Sending a mission to go to Mars and return a sample looks a lot like sending a crew to Mars and returning them safely. There’s a parallelism of ideas there,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate.
What’s the Big Idea?
Collecting rocks from Mars and returning them safely to Earth is a step toward the Obama administration’s stated goal of working toward a manned mission to the Red Planet. One worry of such a mission–that Martian rocks could contaminate Earthly ecosystems–could provide an opportunity to bring astronauts one step closer to setting down on the foreign planet’s surface: “Having astronauts rendezvous with a robotic spacecraft in space to seal off any potential contaminants could be a useful way to team the human exploration and planetary science programs together.”
