ISRO postpones SSLV-D3 launch until August 16
The Indian Space Research Organisation (ISRO) has rescheduled the launch of its latest Earth observation satellite, EOS-08, from August 15 to August 16, 2024. The satellite will be launched aboard the third and final development flight of the Small Satellite Launch Vehicle (SSLV-D3).
ISRO announces new launch date
On Monday, ISRO shared the updated launch schedule via its social media platform X. The launch is now scheduled to take place within a one-hour window, starting at 9:17 am IST on August 16, 2024. The space agency did not disclose the reason for the one-day delay, brushing aside speculations over the reason for the change.
Mission Objectives and Core Components
The EOS-08 mission has important objectives. It is designed to develop a microsatellite, create payload instruments compatible with the microsatellite bus, and introduce new technologies that will be used in future satellites. The success of the mission is crucial because it marks the conclusion of the SSLV Development Project, paving the way for operational missions that will be handled by Indian industry and NewSpace India Limited (NSIL).
The satellite, weighing approximately 175.5 kg, has a mission lifetime of one year and is built on the Microsat/IMS-1 bus. It carries three payloads: the Electro-Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry payload (GNSS-R) and the SiC UV Dosimeter. These payloads are set to play essential roles in various applications, such as satellite-based surveillance, disaster monitoring, environmental tracking and fire detection.
Technological progress
The EOS-08 introduces remarkable developments in satellite technology. It features an Integrated Avionics System that consolidates multiple functions into a single unit and offers up to 400GB of data storage. In addition, it incorporates components such as a structural panel with a PCB, a built-in battery and a flexible solar panel, all aimed at improving the satellite’s efficiency and performance.
Last development flight
The SSLV-D3 mission will be launched from the Satish Dhawan Space Centre in Sriharikota. This mission is crucial as it marks the completion of the SSLV Development Project, which has been instrumental in enhancing India’s capabilities in small satellite launch vehicles. After this launch, SSLV is expected to transition to operational missions, supporting various future satellite deployments.
