On a side note, the notion that the Mars-One project will take off, so to speak, is highly improbable.
If you look at what they have done so far, its just sketches on paper and nothing firm has been developed or made. I see no actual evidence of physics nor actual solid design cases on how the transport craft will actually get them there, nor living conditions....etc. They just ask for money and that's just what they want.
So in essence, they are just getting donations and paying themselves, basically (and hopefully they are actually doing that) to dream of someday reaching mars.
The Islamic authorities need not be overly concerned.
