The Inspiration Mars Foundation, a nonprofit group established by multimillionaire Dennis Tito and others, is aiming to send humans to Mars before the government.
Tito, the world's first space tourist, and others behind the project have plans to send two humans to Mars sometime in 2018.
Experts from the Inspiration Mars Foundation used the recently held Institute of Electronics & Electrical Engineering (IEEE) aerospace conference in Big Sky, Mont., to present the conclusions of a Mars mission-feasibility study.
