The Indian Space Research Organisation (ISRO) achieved a significant milestone with the successful launch of the Earth Observation Satellite-8 (EOS-08) aboard its Small Satellite Launch Vehicle (SSLV-D3) on Friday. The mission, which took off from the Satish Dhawan Space Centre in Sriharikota, represents the third and final developmental flight of the SSLV, a pivotal step in ISRO’s efforts to enhance its satellite launch capabilities.
Initially scheduled for August 15, the launch was postponed to August 16, with a one-hour launch window opening at 09:17 IST. The SSLV-D3 mission aims to complete the SSLV Development Project, setting the stage for operational missions by NewSpace India Limited (NSIL) and the Indian space industry.
The EOS-08 satellite, weighing approximately 175.5 kg, is designed to operate in a circular low Earth orbit at an altitude of 475 km. It carries three advanced payloads: the Electro Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R), and the SiC UV Dosimeter.
The EOIR payload captures high-resolution images in both the Mid-Wave Infrared (MIR) and Long-Wave Infrared (LWIR) bands, useful for various monitoring activities around the clock. The GNSS-R payload is equipped for remote sensing applications, including ocean surface wind analysis, soil moisture assessment, and cryosphere studies. The SiC UV Dosimeter is designed to monitor ultraviolet irradiance and serve as a high-dose alarm sensor for gamma radiation.
The SSLV, a compact, three-stage launch vehicle, is recognized for its low cost and rapid assembly, providing flexibility for accommodating multiple satellites. This makes it an ideal solution for deploying constellations of small satellites and addressing the growing demand for space-based data and services.
The successful launch of EOS-08 underscores ISRO’s commitment to innovation and its growing role in the global space market. By offering cost-effective and reliable launch solutions for small satellites, ISRO aims to strengthen its position and advance India’s capabilities in space exploration.
