In the aftermath, a new Mars mission plan dubbed "Ares" is drawn up, utilising the upgraded Saturn V-B, which has numerous improvements, including the use of solid rocket boosters to double its payload. "Ares" also uses on-orbit assembly of a different long duration Mars-ship using wet-workshop Saturn rocket components as the propulsion systems as well as a Skylab habitat module and external tanks to hold extra fuel. "Ares" performs a Venus flyby reminiscent of the Manned Venus Flyby NASA planned in the aftermath of the original Apollo program, but done in this timeline for gravitational assistance, and finally lands at Mangala Valles on 27 March 1986.
