"The technology to get humans to Mars and keep them alive there exists," Bas Lansdorp told Day 6 host Brent Bambury in an interview that aired this week on CBC Radio.
"The technology to bring humans from Mars back to Earth simply does not exist yet."

The never-to-return explorers will require eight years of training, and the search starts this year.
The flight is scheduled to leave in Sept. 2022.
