PEPP (Planetary Entry Parachute Program) #2

Developed by NASA - Langley Research Center (LRC) / NASA - Jet Propulsion Laboratory (JPL)

Balloon launched on 7/28/1967, from Roswell Industrial Air Center, New Mexico, US

Purpose of the flight and payload description

A saucer-shaped vehicle aimed to test the aerodynamic properties of the parachutes for the Voyager (later renamed Viking) Mars probes.

Launched by a stratospheric balloon after float altitude achieved, the vehicle was released and following seconds of free fall the solid fueled rockets (12 Falcon in one version or 8 Sword-1 motors in the other) ignited and accelerated the test vehicle upwards, simulating a Mars Atmosphere reentry trajectory.

At burn out the aeroshell was released from the dummy payload, which then unfurled the parachutes and landed.

This was the second test of the Aeroshell. Later on, the voyager program was cancelled, and replaced by the much smaller Viking project several years later.
