LEX (sounding rocket)

[1][2][3][4] It had the objective of testing a lithergol fueled rocket engine (an hybrid mixture of solid and liquid propellants - Nylon-metatolueneamine as fuel and mixture of nitric acid and nitrogen tetroxide as oxidizer).

[6][1] All LEX launches were carried out from CERES Ile du Levant.

[1] The first LEX-01 launch on 25 April 1964 was a partial success, with the payload consisting of a telemetry transmitter.

One of these rockets, with an initial mass of 78 kg, reached an altitude of 68 km.

[5][6] These carried the SECT Meteo meteorological payloads, reaching an altitude of more than 100 km, with a parachute ensuring a correct descent for 31 minutes allowing wind measurements over a wide range of altitudes.
