ISRO Launches PSLV-C45 with EMISAT and 28 Satellites

On October 8, 2026, the Indian Space Research Organisation (ISRO) successfully launched its Polar Satellite Launch Vehicle (PSLV-C45) from the Second Launch Pad at the Satish Dhawan Space Centre in Sriharikota. This mission marked a significant milestone as it was the first flight of the new PSLV-QL variant, which features four strap-on motors. The vehicle lifted off at 9:27 IST and successfully injected India's EMISAT satellite into a 748 km sun-synchronous polar orbit 17 minutes and 12 seconds after liftoff. The satellite's solar arrays were deployed automatically, and control was assumed by the ISRO Telemetry Tracking and Command Network in Bengaluru. Over the next few days, EMISAT will be configured for its operational tasks, which involve electromagnetic spectrum measurement.

ISRO's PSLV series has a storied history, having become a reliable workhorse for launching satellites since its inception. The PSLV-QL variant was developed to enhance the vehicle's payload capacity and versatility. The launch of PSLV-C45 not only demonstrated the capabilities of this new variant but also emphasized ISRO's commitment to advancing space technology. The successful deployment of EMISAT and the subsequent delivery of 28 international customer satellites illustrate the organization's growing role in the global space market, with commercial arrangements facilitating this launch.

The implementation of the PSLV-C45 mission involved collaboration among various stakeholders, including ISRO's dedicated teams and international partners. The payloads from the 28 customer satellites, which collectively weigh about 220 kg, are from four countries: Lithuania, Spain, Switzerland, and the USA. After the separation of EMISAT, the fourth stage engines were restarted twice to accurately position the international satellites in a sun-synchronous orbit of 504 km. The last satellite was successfully placed into orbit 1 hour and 55 minutes post-liftoff, showcasing the precision and reliability of the PSLV launch system.

The successful launch of PSLV-C45 presents broader economic and technological benefits. It reinforces India's position as a leader in satellite launches, with over 297 international satellites launched to date. This mission also highlighted the significant involvement of the private sector in supporting ISRO's endeavors. As the PSLV continues to evolve, it contributes to the global space economy by providing affordable launch options for various countries, thus fostering international collaboration in space exploration.

Looking ahead, ISRO plans to continue leveraging the advancements made with the PSLV-QL variant for future missions. The next mission, PSLV-C46, is expected to launch the RISAT-2B satellite in May 2019. These upcoming launches will further demonstrate ISRO's capabilities and commitment to expanding its satellite launch services, enhancing global connectivity, and supporting scientific research through space technology.
