  • spc_horn_000087.pdf

    From the summary: "Both [guidance] schemes steer toward a specified end point. The MIT scheme uses thrust to cancel out the effective gravity, a nonlinear term, which may be inefficient in certain cases. The MSFC scheme is more closely connected with calculus of variations and optimization theory in a reasonable degree of approximation."

    From the abstract: "This report discusses the iterative guidance mode and its application to three-dimensional upper stage vacuum flight. It is an inertial or closed system mode in that the only inputs required after liftoff are available from the onboard navigation system. That is, the iterative scheme computes steering commands as a function of the state and of the vehicle - velocity, position, longitudinal acceleration, and gravitational acceleration - and the desired cutoff conditions. The guidance commands are updated each guidance cycle, using the updated state of the vehicle. The iterative guidance scheme is a path adaptive guidance scheme in that it will retain its optimization properties under all expected types and magnitudes of vehicle perturbations without any loss in accuracy at liftoff."

  • spc_stnv_001_003.pdf

    The leaflet outlines the history of Saturn launches and gives a physical description of the rocket. The description includes a diagram of each stage; specifications of each stage's thrust, propellants, liftoff weight, and burning time; and engine specifications.
  • spaceflight_1_2.pdf

    Appears to be a rough dfraft with editorial comments and revision notes. Includes references to figures and tables.; Page 31 is missing. Pages 37 through 44 do not exist; there is a note about this on page 36. Page 67 also does not exist.

    Saturn and Apollo hardware will not have realized their ultimate potential for space exploration after the project lunar landing is complete. To accomplish the Apollo lunar landing program, an immense backlog of technology, facilities, and booster capability will have been built up, and we believe proper utilization of this resource will fill the needs for planetary, lunar and earth orbital space exploration for years to come.
