New Private Mars Venture Announced

In 2001, millionaire Dennis Tito became the first private person to fly into space.  Now he wants to become the first person responsible for flying to Mars and back.

His project, called “Mission for America” is scheduled to launch in January, 2018 and is a product of the Inspiration Mars Foundation.

“It is intended to encourage all Americans to believe again, in doing hard things that make our nation great, while inspiring youth through science, technology, engineering and mathematics education and motivation,” his announcement reads.

The planned trip to Mars and back would take 501 days.  All the details of the mission will be announced at the National Press Club in Washington D.C. on Feb. 27.

Every two years or so the orbital alignments of Earth and Mars are such that a spaceship would use less fuel to make the 350 million mile journey.  January, 2018 will see the two planets in that situation.

The mission is actually only a fly-by of the red planet apparently using a modified SpaceX Dragon capsule, which is a bit disappointing, but at least it is far more ambitious than anything NASA can plan given its budgetary restraints.  The main challenge faced by the two astronauts who will make the trip, aside from spending almost two and a half years in confined quarters, will be cosmic and solar radiation. How their bodies will respond to experiencing zero gravity for that length of time will also be a consideration.

A fly-by of Mars is much less complicated and doable than landing on the planet.  It was a major feat of engineering skill just to get the big Curiosity rover to the Martian surface. Astronauts would require a much larger capsule.  Mars’ thin atmosphere makes aerobraking  more hazardous and might require a technique not yet invented.
