PSLV-C60 SpaDeX Mission: POEM-4 Expands Horizons in Space Research
The PSLV-C60 SpaDeX mission marks a milestone for ISRO’s Polar Synchronous Launch Vehicle (PSLV) programme with the fourth deployment of the Orbital Experiment Module (POEM). This innovative platform utilises the spent fourth stage of the PSLV to conduct extended-duration in-orbit microgravity experiments, preventing it from becoming space debris. ISRO’s POEM-4 hosts 24 experimental payloads, tripling its capacity compared to the previous mission, POEM-3.
Advanced Payloads from ISRO/DOS Centres
ISRO has contributed 14 cutting-edge payloads focusing on robotics, sensors, space science, and proof-of-concept experiments. Highlights include:
- Walking Robotic Arm (RRM-TD): Developed by IISU, this 7-degree-of-freedom robotic manipulator demonstrates inchworm-like movement for in-orbit servicing and inspection.
- Debris Capture Robotic Manipulator: A VSSC innovation designed to capture and manipulate tethered debris, aiding future space clean-up missions.
- Gradient Control Reaction Wheel Assembly (RWA): This IISU payload enhances attitude stabilisation of the POEM platform using advanced reaction wheels.
