Correct Answer :   SpaDeX Mission

The SpaDeX (Space Docking Experiment) Mission, launched by ISRO using PSLV-C60, aims to test crucial technologies like docking, undocking, and rendezvous between two spacecraft, SDX01 and SDX02, in low-Earth orbit.

These capabilities are essential for advanced space missions, including lunar missions like Chandrayaan-4.

The mission incorporates innovative GNSS-based systems and RODP processors for accurate positioning and velocity measurements, showcasing ISRO's technological advancements in orbital mechanics and spacecraft operations.

Correct Answer :   ISRO

* ISRO is set to launch the SpaDeX mission in December 2024 aboard PSLV-C60, aiming to demonstrate in-space docking technology using two small spacecraft, SDX01 (Chaser) and SDX02 (Target).

* This achievement will position India as the fourth nation to master space docking, a critical capability for advanced space missions.

* The mission’s objectives include demonstrating autonomous rendezvous, docking, and undocking technologies, as well as power transfer and payload operations.

* SpaDeX will play a vital role in advancing ISRO’s future endeavours, including the Bharatiya Antariksha Station (BAS) and satellite servicing missions.

Correct Answer :   59th

* The European Space Agency's PROBA-3 mission was launched aboard PSLV-C59, marking the 61st flight of the PSLV (Polar Satellite Launch Vehicle).

* This mission demonstrated ISRO's proficiency in satellite deployment and highlighted its collaboration with the European Space Agency and NewSpace India Limited.

* The PSLV has been a reliable workhorse for ISRO, and this launch utilized the PSLV-XL configuration, a variation optimized for specific missions.

* This milestone underlines ISRO’s sustained excellence in space exploration and international cooperation.
