US private sector hopes to send older couple to Mars

A team led by millionaire and former space tourist Dennis Tito plans to send a "tested couple" to Mars and back in a privately funded mission.

The Inspiration Mars Foundation plans to start its one-and-a-half-year mission in January 2018.

The foundation has carried out a study which it says shows that it is feasible to achieve such a mission using existing technology.

The group still has to raise funding for their mission.
