It is clear when you see Dennis Tito speak about space exploration he is a man with a passion.
And now he is a man with a mission.
Tito, the world's first space tourist, has revealed his plan for "Inspiration Mars" a manned mission to the Red Planet.
The privately funded mission, paid for partly by Tito, will take 501 days to journey around the planet. It is only made possible by a rare planetary alignment that occurs 5 years from now which will see Mars closer to the Earth, shortening the trip.
The two US citizens (a man and a woman and preferably a 'tried and tested couple') will be launched into space and will be able to return to Earth by using the gravitational influence of Mars to "slingshot" their vehicle back.
In a press conference this evening Tito and his team highlighted the trials and triumphs that will come with the mission; "we are approaching the limits of science using robots like the Mars Rover. Two people will be sent to Mars, but the whole world will be along for the ride."
The goal is to inspire the population and to help pave the way for an eventual government-funded mission to the surface of Mars - but that is some way off.
Tito has garnered some high-profile supporters but he needs more, the cost is estimated to reach up to £1.3 billion.
But it is not just getting there or money that will prove challenging. Jokingly Tito added, "If I were 30 years younger I still would not be going." 501 days in a space of 35 cubic metres is going to be a real challenge, so the crew selection process is going to be rigourous, and there will be a lot of science to do when they are there, as well as vitally staying healthy.
