Megan Garber for The Atlantic:
If you are at least 18 years of age and curious and capable and resourceful, with a capacity for self-reflection, an ability to trust other people, and a deep sense of purpose, then you can to go to Mars. Maybe. The Mars One project, which is planning to send a group of people to colonize the Red Planet, has officially opened its applications process to public voting. If you are one of the people ultimately selected for the program, if all goes according to plan, you will depart Earth in 2023 to follow in the epic footsteps of Magellan and Gagarin and Armstrong, staking a claim for humanity’s extension into a new and unknown world.
The only catch? You will not be coming back.
