Isro set to launch PSLV-C60 Spadex Space Docking mission at 10pm today

BENGALURU: Tonight, a few milliseconds past 10pm, India is poised to launch its Space Docking Experiment (SpaDeX) mission — the PSLV-C60 rocket will carry two small spacecraft, each weighing approximately 220 kg, into a 470 km circular orbit.This technology demonstration mission aims to showcase India's capability in performing complex in-space docking maneuvers, a crucial technology for future space endeavors including lunar missions and the planned Bharatiya Antariksh Station (BAS). A success will put India in an elite group of nations with these capabilities.The mission will demonstrate several indigenous technologies, including a sophisticated docking mechanism, rendezvous sensors, and inter-satellite communication systems. The two spacecraft—designated as SDX01 (Chaser) and SDX02 (Target)—will perform a carefully choreographed series of maneuvers, gradually reducing their separation from 20 km to just a few meters before attempting the actual docking — expected 10 days from the launch.The technology is particularly challenging due to the small size of the spacecraft, requiring extremely precise maneuvering capabilities.Following the docking demonstration, both spacecraft will carry out secondary objectives, including power transfer experiments and payload operations. SDX01 will carry a high-resolution camera, while SDX02 will host a multi-spectral payload and radiation monitor for scientific studies.TOI has already reported about the 24 experimental payloads the PSLV Orbital Experimental Module (POEM) will carry.
