Spiegel.de has an update on the Mars One project. See Ultimate Reality TV: A Crazy Plan for a Mars Colony.
Of the 200,000 original applicants there are 704 contenders who made the first cut. That number will be whittled down to 100 who will be divided into 25 four person teams. Reality show type competition will reduce the number to six teams who should commence survival training next year.
If the project raises enough money to get off the ground, a team of four will take off for Mars in 2025 never to be seen on Earth again, except on the Mars reality TV show. That TV show is expected to provide the financing for the whole thing. So a lot depends on the entertainment value.
Watching four people go crazy slowly might actually be entertaining. The producers back home will be frantically trying to manipulate the scenes, like they do in the Earth bound reality shows, and if that's part of the show too, it could have an audience.
Meanwhile, the robots seem to be doing a good job, so let's let them do the exploratory work.
Via Bastiat.mises.org where Christopher Westley attempts to apply an Austrian economics theory to explain why anyone would want to make the trip. I'm not smart enough to agree with him, except that part about doing it outside governments, so it's best that you read it for yourself.
