TheVesta sounding rocket, conceived in 1962 by theLaboratoire de Recherches Balistiques et Aérodynamiques (LRBA), a specializedFrench Army research facility focused on liquid-propelled rocket development.[1][2][3] The initial letter "V" in its name is derived from the city ofVernon.
It was the outcome of an initiative byCNES with the purpose of enabling transportation of more substantial experiments to greater altitudes than theVéronique sounding rocket, also created by the LRBA and in active service at the time.[1][2]
Operated by a 160 kN thrust engine using a combination ofnitric acid andturpentine as propellants, the Vesta rocket was 10.2 meters tall with a diameter of 1 meter.[3][4] Weighing 5.1 tons excluding its payload, Vesta had the capability to send a 500 kg to an altitude of 400 km.[1][2][3]
Between 1965 and 1969 a total of five Vesta rockets were launched.[5] These launches took place from bothCIEES andKourou.[1][2][3][5] The first two launches primarily served as validation tests for the rocket's operation,[1] whereas the subsequent three carried out scientific experiments.[2][3]
Apig-tailed macaque namedMartine was launched on March 7, 1967, and another namedPierette on March 13.[2] These suborbital flights reached 243 km (151 mi) and 234 km (145 mi), respectively. Martine became the first monkey to survive more than a couple of hours after flying above the international definition of the edge of space. (Ham andEnos, launched earlier by the United States, were chimpanzees).[6]
