Description:If you’re a middle-aged married couple with a sense of adventure… how about a trip to Mars?
NASA engineer turned multi-millionaire Dennis Tito has announced plans to send a couple on a privately-built spaceship to slingshot on a fly-by around the Red Planet.
Tito says he hopes to make the launch within the next five years, at an estimated price tag of more than $1 billion.
The trip will confine the couple in a cramped space capsule for an estimated 501 days.(0:51)
