Apollo 13 mission to land on the Moon. The astronauts' mission insignia was sculpted as a medallion depicting "Steeds of Apollo" by Lumen Martin Winter and was struck by the Franklin Mint. The Apollo 13 mission was to explore the Fra Mauro formation, or Fra Mauro highlands, named after the diameter Fra Mauro crater located within it. It is a widespread, hilly selenological area thought to be composed of ejecta from the impact that formed Mare Imbrium. The next Apollo mission, Apollo 14, eventually made a successful flight to Fra Mauro. April 14, 1970 UTC (April 13, 21:07:53 CST) April 15, 1970,
Apollo Applications Program Taxi hardware derived from the basic Apollo program would allow crews to be rotated to the ever-expanding, and eventually permanent, lunar base. A nuclear reactor would provide power. Phases: To support longer stays on the Moon, NASA also studied a number of simple Lunar Escape Systems as a means of returning two astronauts from the lunar surface to an orbiting CSM if the Lunar Module ascent-stage engine failed to ignite. Another plan for Apollo-based extended-duration manned spaceflight would use a Saturn V to send three men on a Manned Venus Flyby, using the Saturn S-IVB stage as a "wet workshop".
