The RH300 sounding rocket, developed by Vikram Sarabhai Space Centre as part of a study to enrich available atmospheric data, was launched tonight from the Thumba Equatorial Rocket Launching Station. This was the 21st launch of RH300 sounding rocket. The shores of Thumba reverberated with the thunderous boom of the rocket propulsion, as the sight of white and blue trail pattern formed by the TMA payload brought jubilation to the scientists and engineers.

The objective of the experiment is to measure neutral wind in the dynamo region (80-120 km) of the equatorial ionosphere using the indigenously developed Electron Density and Neutral Wind Probe and perform cross-validation using an independent Tri Methyl Aluminium release technique.
