Indian Space Research Organization (ISRO) is soon going to launch its latest Earth Observation Satellite i.e. EOS-8. The launching will take place from Satish Dhawan Space Center in Sriharikota. This satellite weighing 175.5 kg will work for environmental monitoring, disaster management and technical demonstration.
EOS-8 carries three specialized state-of-the-art payloads – Electro Optical Infrared Payload (EOIR), Global Navigation Satellite System Reflectometry Payload (GNSS-R) and SiC UV Dosimeter. In this, EOIR will take mid and long wave infrared photographs during day and night. This satellite will be launched on August 15 at 9.17 am.

Will save people from natural disasters
These pictures will provide information about disasters. Like forest fire, volcanic activities. The wind on the sea surface will be analyzed through GNSS-R. Soil moisture and flooding will be detected. Whereas ultraviolet radiation will be tested with SiC UV dosimeter. Which will help in Gaganyaan mission.

Will help in communication and positioning
The EOS-8 satellite will revolve in a low orbit above the Earth i.e. at an altitude of 475 kilometers. From here this satellite will also provide many other technical help. Like integrated avionics system. Inside it is the Communication, Baseband, Storage and Positioning (CBSP) package. That means a single unit can do many types of work. It has a capacity of 400 GB data storage.

The flight will be completed by SSLV rocket
The lifespan of this mission is one year. If it goes further, the better. SSLV rocket will be used to take it to space. That is, Small Satellite Launch Vehicle. D3 in SSLV-D3 means third demonstration flight. This rocket is designed for launching mini, micro and nano satellites.
After this launch, SSLV will get the status of a fully operational rocket. Before this, there have been two flights of this rocket. The first flight of SSLV-D1 took place on 7 August 2022. The next flight i.e. SSLV-D2 was done on 10 February 2023. Three satellites were sent in it. EOS-07, Janus-1 and AzaadiSAT-2.

What will this rocket of ISRO do?
SSLV is used for launching small satellites. It is a small-lift launch vehicle. With this, satellites weighing up to 500 kg can be sent below 500 km in low earth orbit or satellites weighing 300 kg can be sent into sun synchronous orbit. The altitude of this orbit is above 500km.
SSLV is ready in 72 hours
The length of SSLV is 34 meters. Its diameter is 2 meters. The weight of SSLV is 120 tonnes. SSLV can deliver payloads of 10 to 500 kg to a distance of 500 kilometers. SSLV is ready in just 72 hours. At present SSLV is launched from launch pad 1 of Satish Dhawan Space Center in Sriharikota.

New spaceport is being built in Tamil Nadu
A separate Small Satellite Launch Complex (SSLC) is being built for the launch of this rocket. A new spaceport is being built in Kulashekharapatnam, Tamil Nadu. Then SSLV will be launched from there. The need for SSLV arose because launching small satellites had to wait for PSLV to be built. That was also expensive. They had to be assembled and sent with larger satellites.
SSLV is five-six times cheaper than PSLV
Internationally, small satellites are coming in large quantities. The market for their launches is increasing. That’s why ISRO made this rocket. An SSLV rocket will cost Rs 30 crore. Whereas PSLV earns Rs 130 to 200 crore.
