American manned Mars expedition will happen in 2003

"American manned Mars expedition. Study 1983. Chemically-powered Mars flyby-rendezvous landing mission designed by SAIC under contract to the Planetary Society in 1983. The risky scenario involved only one chance for the crew to rendezvous and dock with an unmanned Earth Return Vehicle as it whizzed by Mars. The 1096 day mission would depart on 5 June 2003."
