Navy Viking sounding rocket was first important US indigenous sounding rocket. It was eventually developed into the Vanguard satellite launcher.
Reaction Motors began design and development of rocket engine for the Navy Viking sounding rocket.
Upper-air pressures and temperatures; earth photography research. Engine cut-out after 55 seconds. Launched at 0914 local time. Reached 80.5 km.
Upper-air pressures and temperatures; earth photography research. Engine cut-out early after 49 seconds. . Launched at 0957 local time. Reached 52 km.
Solar and cosmic radiation; pressure-temperature; earth photography research. Veered off-course; engine cut-off at T+60 seconds. Launched at 1444 local time. Reached 80.5 km.
Cosmic radiation; upper-air pressures and temperatures research. Ship launch. Launched at 1608 local time. Reached 169 km. NRL Viking No. 4 research rocket fired from the USS Norton Sound, near Jarvis Island in the Pacific (0.2 N 161.4 W), at the intersection of the geographic and geomagnetic equators. It set an altitude record for an American single-stage rocket and was the first firing of the Viking from shipboard.
Ionosphere; solar radiation; pressure-temperature; earth photography research. Launched at 1018 local time. Reached 175 km.
Upper-air pressure, density and composition; solar radiation; ionosphere research. Fin tore loose. Launched at 0004 local time. Reached 64.8 km.
Upper-air pressure, density; solar and cosmic radiation research. Launched at 1100 local time. Reached 219 km. A Navy Viking 7 rocket set an altitude record for single-stage rockets and reaching a speed of 6,600 kph. This was the highest flight of the original airframe design.
Solar and cosmic radiation; photography research. Ran out of fuel. Launched at 1438 local time. Reached 219 km.
Check power plant, controls, performance, and skill temperatures; upper-air pressure, density, winds, ionisation; cosmic rays; photography research. Launched at 1000 local time. Reached 219 km.
Re-entry nose-cone heat transfer experiment; photography research. Launched at 1000 local time. Reached 254 km.
Re-entry nose-cone heat transfer experiment; photography; atmosphere research. Launched at 1455 local time. Reached 232 km.
First Vanguard test; re-entry studies; not a vertical firing. Launched at 0103 local time. First test rocket in the IGY-U.S. satellite program, a one-stage NRL Viking, attained an altitude of 176 km and a speed of 6,400 kph. Viking No. 13 carried a "minitrack" radio transmitter which was ejected at 80 km and tracked.
Test of Vanguard third-stage separation and firing at altitude.Launched at 0129 local time. Reached km.
