⇑ Mission List ⇑ Designation: Apollo S1-3 L AS(U)-3 Description: 3rd Apollo 3-stage Saturn C-1 unmanned CSM suborbital

The August 1960 long range plan for the manned spaceflight program called for a third three-stage Saturn C-1 suborbital flight of an Apollo Command Module in 1964: "reentry of a developmental capsule along the upper limit of the altutude corridor at parabolic velocity," thus simulating a return from the Moon. The launch date of May 1964 is interpolated. NASA announced the redesign of the Saturn C-1 as a two-stage launch vehicle on 1 June 1961. References: Disher, John H. 1960.
