Quiz: How Well Do You Know ISRO's Space Missions?

India needed a dedicated satellite system to connect its vast geography. ISRO developed a series that brought television broadcasts, weather data, and telephone connectivity under one national programme. It marked a turning point in how India used space technology for civilian and governmental communication needs.

Reusable launch vehicles return to Earth after a mission, reducing future launch costs. ISRO tested a scaled demonstrator in 2016 to validate aerodynamics, navigation, and re-entry technologies. This experiment was a foundational step towards building a fully reusable Indian launch system.

Cryogenic engines operate using propellants stored at extremely low temperatures, delivering far greater efficiency than conventional rocket fuels. They are ideal for placing heavy satellites into high orbits. The CE-20 is a domestically developed engine used in the upper stage of the GSLV Mk III.

The GSLV Mk III is India's most powerful operational launch vehicle, built to carry heavier satellites to geostationary orbits. Developing it required years of indigenous engine development and structural testing. Its first successful orbital flight reduced India's dependence on foreign rockets.

Launching multiple satellites in one flight requires precise deployment sequencing and orbital slot management. ISRO demonstrated exceptional coordination by deploying a record number of satellites, most belonging to international customers. This mission placed India among the leading providers of commercial launch services.
