India Launches X-ray Polarimeter Satellite, Tests Fuel Cell for Space Station Power

India celebrated the arrival of the New Year with a significant achievement in space exploration. On January 1, 2024, the Indian Space Research Organisation (ISRO) successfully launched its X-ray Polarimeter Satellite (XPoSat) onboard the Polar Satellite Launch Vehicle-C58 (PSLV-C58). This marks the first space mission for ISRO on New Year’s Day.

The PSLV-C58, standing at a height of 44.4 meters and weighing 260 tons, took off from the Satish Dhawan Space Centre. Alongside XPoSat, the rocket carried 10 additional experimental payloads on its fourth stage. The launch was met with applause from spectators as the rocket ascended into the sky with a thunderous sound.

ISRO Chairman S Somanath expressed satisfaction with the mission, stating that the orbit achieved for XPoSat is excellent, with a deviation of only three kilometers. After being deployed at an altitude of approximately 650 kilometers, XPoSat’s solar panels were successfully deployed.

However, the significance of this mission extends beyond the deployment of XPoSat. ISRO also utilized the fourth stage of the rocket, known as the PS4 stage, as an orbital platform with 10 experimental payloads. By bringing down the stage to a lower orbit of 350 kilometers, ISRO aims to minimize space debris. The remaining fuel on the fourth stage will be disposed of in a unique manner, ensuring safety for future atmospheric reentry experiments.

Of particular importance is ISRO’s testing of a fuel cell that may power the Indian space station in the future. This is a crucial step towards long-duration human space missions and establishing a permanent presence in space. Additionally, ISRO will test silicon-based high-energy cells as part of its ongoing research and development efforts.

XPoSat, the first dedicated scientific satellite from ISRO, is equipped with state-of-the-art instruments to measure X-ray polarization and carry out spectral and temporal studies of cosmic X-ray sources. Through this mission, ISRO aims to expand our understanding of celestial objects and the X-ray emissions they emit.

As India continues to make strides in space exploration, the successful launch of XPoSat and the testing of the fuel cell technology bring the country closer to achieving its goal of establishing a space station and conducting cutting-edge research in space.
