Associated Launch Vehicles
  • Vesta French sounding rocket. In the late 1950's LRBA studied several possible configurations for a 'Super Veronique' sounding rocket, with engines of 80 to 250 kN to carry a payload of 100 kg up to 600 km altitude. In 1962 CNES ordered the Vesta configuration. Static tests in 1964 led to a modest series of launches in 1965-1969. More...

Associated Propellants
  • Nitric acid/Turpentine Drawing on the German World War II Wasserfall rocket, nitric acid (HNO3) became the early storable oxidiser of choice for missiles and upper stages of the 1950's. To overcome various problems with its use, it was necessary to combine the nitric acid with N2O4 and passivation compounds. These formulae were considered extremely secret at the time. By the late 1950's it was apparent that N2O4 by itself was a better oxidiser. Therefore nitric acid was almost entirely replaced by pure N2O4 in storable liquid fuel rocket engines developed after 1960. More...
