The former NASA astronaut expressed his views when he attended the 34th Space Development Conference (ISDC2015), in Toronto as the keynote speaker this weekend. The conference, conducted by the National Space Society brought together scientists, businesses, educators, and students from around the world to discuss the future of space.
Buzz Aldrin's vision is to have people on Mars by 2035, but in various stages which would continue in intervals. The astronaut also said that the Mars exploration will not be a race about who reaches first, but a collaborative effort among the countries.
He also explained how a one-way trip to Mars would reduce costs, as it could be done with less expenses.
Aldrin's ideas sound similar to the Mars One Project, a privately run initiative aiming to establish a permanent human settlement on Mars by 2027.
