Irish Mars One candidate speaks out against the organisation

An Irish shortlisted candidate for a one-way ticket to Mars has spoken out against the Mars One mission, fearing its actions could damage the future of science.

Dr. Joseph Roche, an assistant professor at Trinity College, is in the organisation's shortlist of 100 candidates who are willing to take a journey to Mars, and never return to Earth.

Mars One is the brainchild of Dutch entrepreneur Bas Lansdrop, and Dutch scientist Arno Wielders. It aims to establish a human settlement on Mars.
