The Indian Space Research Organisation (ISRO) has launched a sounding rocket to study attitudinal variations in the neutral winds and plasma dynamics from Sriharikota spaceport. ISRO has developed a series of sounding rockets called Rohini series. Sounding rockets are one or two-stage solid propellant rockets used for probing the upper atmospheric regions and for space research. They also serve as easily affordable platforms to test or prove prototypes of new components or subsystems intended for use in launch vehicles and satellites.
