GS Paper - 3 Space Technology

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, important among them being RH-200, RH-300 and RH-560, number in the name indicating the diameter of the rocket in mm, according to the Bengaluru-headquartered space agency.

What

  1. Launch of sounding rocket (RH-560) to study attitudinal variations in the neutral winds and plasma dynamics carried out on 12 March 2021 at SDSC SHAR, Sriharikota.
  2. Sounding rockets are one or two stage solid propellant rockets used for probing the upper atmospheric regions and for space research.
  3. 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.
  4. At present, Isro has three versions of sounding rockets- RH-200, RH-300-Mk-II and RH-560-Mk-II capable of carrying 8-100kg payload and reach an altitude of 80 to 475km.
  5. Isro started launching indigenously made sounding rockets from 1965, and experience gained was of immense value in the mastering of solid propellant technology.
