A Manned Mission to Mars This Decade?

See on Scoop.itThe NewSpace Daily

Because of the huge expense and perceived need for gargantuan launch vehicles that don’t yet exist, the conventional wisdom in the space community is that a human mission to Mars is many years off, perhaps not to be achieved until 2030 or so. But space adventurer Dennis Tito is about to announce a plan to do one privately about five years from now.

 

What’s the catch? Well, first of all, there are no plans to land on the planet itself, which is one of the hardest parts of a Mars mission, due to its thin atmosphere, demanding a lot of propellant that must be hauled all the way there. In fact, there are no plans to even go into orbit around the planet, which itself would also be costly in propellant, both to enter and depart. The mission is much simpler — a two-person flyby on a so-called “free return” trajectory, allowing it to get back to earth without the need for an engine burn at Mars. The total trip time will be about a year and a half. It would be the ultimate human adventure to date.
