Farside


American sounding rocket. Project Farside was an attempt to reach extreme altitudes with the rockoon concept. Using a four-stage solid-propellant rocket hung below a 106 188-m3 (3 750 000-ft3) balloon, altitudes approaching 6437 km (4000 mi) were reached during the fall of 1957. Farside was a four stage vehicle consisting of 4 x Recruit + 1 x Recruit + 4 x Arrow II + 1 x Arrow II.

Farside was an Air Force Office of Scientific Research project, using various instruments provided by the University of Maryland. Six rockets were built by Aeronutronic Systems, Inc. Bad telemetry precluded the discovery of the Van Allen belts during the Farside shots near Eniwetok.

  • Rockoon The Rockoon (balloon-launched rocket) consisted of a small high-performance sounding rocket launched from a balloon above most of the atmosphere. The Rockoon low-cost technique was conceived during an Aerobee firing cruse of the Norton Sound in March 1949. Rockoons were first launched from icebreaker Eastwind off Greenland by an ONR group under James A. Van Allen. They were later used by ONR and University of Iowa research groups in 1953-55 and 1957, from ships in sea between Boston and Thule, Greenland. A variety of upper stage rocket stages were used.
