ISRO to Launch Earth Observation Satellite-8 on August 15 from Sriharikota
ISRO’s Earth Observation Satellite-8 (EOS-8) is scheduled for launch on August 15 from Sriharikota, Andhra Pradesh, using the Small Satellite Launch Vehicle (SSLV)-D3. This launch will mark the third and final flight of the SSLV Development Project, paving the way for future operational missions by Indian industry and NSIL.
Mission Objectives
The primary goals of the EOS-8 mission include designing and developing a microsatellite, creating payload instruments compatible with the microsatellite bus, and incorporating new technologies for future operational satellites.
Payloads on EOS-8
| Payload | Function |
|---|---|
| Electro Optical Infrared Payload (EOIR) | Captures images in Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands for applications like surveillance, disaster monitoring, and environmental monitoring. |
| Global Navigation Satellite System-Reflectometry Payload (GNSS-R) | Uses GNSS-R-based remote sensing for ocean surface wind analysis, soil moisture assessment, and flood detection. |
| SiC UV Dosimeter | Monitors UV irradiance and serves as a high-dose alarm sensor for gamma radiation. |
The spacecraft is designed for a mission duration of one year.
Doubts Revealed
ISRO -: ISRO stands for Indian Space Research Organisation. It is India’s space agency responsible for space research and launching satellites.
Earth Observation Satellite-8 (EOS-8) -: EOS-8 is a satellite that will observe and take pictures of the Earth from space. It helps in studying weather, land, and oceans.
Sriharikota -: Sriharikota is an island in Andhra Pradesh, India. It is where ISRO has its main launch site for sending rockets into space.
Small Satellite Launch Vehicle (SSLV)-D3 -: SSLV-D3 is a type of rocket designed by ISRO to carry small satellites into space. It is smaller and cheaper than other rockets.
microsatellite -: A microsatellite is a very small satellite, usually weighing less than 100 kilograms. It is used for specific tasks like imaging or communication.
EOIR -: EOIR stands for Electro-Optical Infrared. It is a type of camera on the satellite that takes pictures using both visible light and infrared light.
GNSS-R -: GNSS-R stands for Global Navigation Satellite System-Reflectometry. It uses signals from navigation satellites to study the Earth’s surface, like oceans and land.
SiC UV Dosimeter -: A SiC UV Dosimeter is a device on the satellite that measures ultraviolet (UV) radiation from the sun. It helps in studying the effects of UV light on Earth.
NSIL -: NSIL stands for NewSpace India Limited. It is a company that works with ISRO to promote and sell space products and services.
