Mars One, the organization attempting to send small teams of astronauts on a one-way trip to Mars, has made its first round of applicant decisions, selecting just over 1,000 people to move on to the next stage of what it hopes will be a decade-long, televised training and colonization mission. Today, 1,058 of the roughly 200,000 people who applied were told that they had made the cut. Between 2014 and 2015, all but a few dozen of those will be weeded out, leaving a final set of four-person teams that will theoretically begin heading to Mars by 2025. Before then, though, there’s a long process of testing, prototyping, and fundraising ahead of the company.
