Rehbar is a series of sounding rockets launched into the upper atmosphere by Pakistan's Space and Upper Atmosphere Research Commission (SUPARCO). Rehbar-I was the first rocket launched by SUPARCO, on 7 June 1962.[1][2] Rehbar-I was a two-staged solid fuel rocket.
Various sounding rocket models were launched by Pakistan approximately 200 times between 1962 and 1972. Twenty-four of those flights were in the Rehbar series.[3][4] The Rehbar series of flights utilized no less than three and possibly four different sounding rockets. The rockets used were Centaure,[5] Judi-Dart,[6] Nike-Cajun,[7] and according to one source, Nike-Apache.[3][8] Other sounding rockets used by Pakistan were Dragon 2B,[9] Petrel,[10] and Skua.[4][11] Rehbar literally means "one who leads the way" in Urdu.
