A team from the foundation is presenting the results of a mission-feasibility study next weekend at an Institute of Electronics and Electrical Engineering (IEEE) aerospace conference in Big Sky, Mont.
"All of the work done to date show the mission is possible, just barely," said Taber MacCallum, CEO and chief technology officer for Paragon Space Development Corporation and the Inspiration Mars Foundation's chief technology officer, during a press conference in Washington on Wednesday.
At the same time, however, the study also shows that it will take the Orion capsule and the space-launch system NASA is working on to pull off a mission to explore Mars with a crew of scientists, he said.
The Inspiration Mars mission is an austere one whose schedule is dictated by a very favorable alignment between Earth and Mars in 2018. The alignment allows a simple round trip to take 501 days, and the alignment won't appear again until 2031.
The two-member crew, a man and a woman, would launch Jan. 5, 2018, take one swing around Mars, coming to within 100 miles of the surface on Aug. 21, then return to Earth in an approach and reentry no one has tried before, landing on May 21, 2019.
In a version of the feasibility study papered for the IEEE presentation next Sunday, Tito and colleagues from three aerospace companies, NASA's Ames Research Center, and Baylor University's Center for Space Medicine in Houston envision a Spartan craft where sponge baths replace showers and the crew will recycle water and oxygen with technologies similar to those used on the International Space Station.
