Significance of the CMS-01 Launch

Other than the fact that the CMS-01 satellite will help in boosting communications across India, the launch of the satellite also shows that the Indian space programme is back on track as the COVID-19 pandemic had thrown launch schedules off-gear.

Before the CMS-01, ISRO has launched the Earth Observation Satellite – I (EOS-1) and nine other smaller satellites since its personnel returned to active duty at the Sriharikota space drome in November 2020.

The Gaganyaan mission, a human spaceflight project, has also suffered from the impacts of the COVID-19 pandemic. Certain stages of the project such as uncrewed launches using robots are expected to be launched in late 2021 according to ISRO chairman K Sivan.
