7. Parachute deployments at high speeds were tested using test vehicles launched by balloons and Honest John-Nike rockets. The full-scale tests lifted a 4.6-meter simulated entry body to about 40 000 meters, the point at which Earth's atmosphere approached the 10-millibar pressure of Mars. At that altitude, the shell would be released. Twelve small rockets would accelerate it to mach 1.2. The 26-meter test chute would then be deployed and, with an instrument package, would subsequently be separated from the shell. John C. McFall of Langley was NASA project manager for the Planetary Entry Parachute Project. The balloons were launched by the Air Force Cambridge Research Laboratory at the balloon launch facility, Holloman Air Force Base, N. Mex., and Walker Air Force Base, N. Mex. The balloons were fabricated by G. T. Schjeldahl Co., Northfield, Minn. Overall cost of the project was far below that projected for similar tests using the Little Joe II rocket. Honest John-Nikes were launched at the White Sands Missile Range, New Mexico. Consult the following documents: H. Lee Dickinson to Richard T.
