The Indian Space Research Organization (ISRO) is soon going to launch its latest Earth Observation Satellite i.e. EOS-8. The launch 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 has three special 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 images during day and night. ISRO has not disclosed when this satellite will be launched.

will save people from natural disasters
These pictures will provide information about disasters. Such as forest fires, volcanic activities. Through GNSS-R, the air on the sea surface will be analyzed. Soil moisture and floods will be detected. Ultraviolet radiation will be checked with SiC UV dosimeter. Which will help in the Gaganyaan mission.
Will help in communication and positioning
The EOS-8 satellite will orbit 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 assistance. Such as Integrated Avionics System. It has a Communication, Baseband, Storage and Positioning (CBSP) package. That is, a single unit can perform many types of tasks. It has a data storage capacity of 400 GB.

The flight will be completed with SSLV rocket
The life of this mission is one year. If it lasts longer, it would be 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 has been made for launching mini, micro and nano satellites.
After this launch, SSLV will get the status of a fully operational rocket. Earlier, this rocket has had two flights. The first flight SSLV-D1 was 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.

Will this rocket of ISRO do the job?
SSLV is used for launching small satellites. It is a small-lift launch vehicle. It can send satellites weighing up to 500kg into low Earth orbit below 500km or satellites weighing 300kg into sun synchronous orbit. The height of this orbit is above 500km.
SSLV is ready in 72 hours
The length of SSLV is 34 meters. Its diameter is 2 meters. SSLV weighs 120 tonnes. SSLV can deliver payloads of 10 to 500 kg up to 500 kilometers. SSLV is ready in just 72 hours. Currently, SSLV is launched from Launch Pad 1 of Satish Dhawan Space Center in Sriharikota.

A 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 Kulasekharapatnam, Tamil Nadu. Then the launch of SSLV will be done from there. SSLV was needed because to launch small satellites, one had to wait for the PSLV to be made. That was also expensive. They had to be assembled and sent along with big satellites.
SSLV is five to six times cheaper than PSLV
Small satellites are coming in large numbers at the international level. The market for their launch is growing. That is why ISRO built this rocket. An SSLV rocket will cost Rs 30 crore. Whereas a PSLV costs Rs 130 to 200 crore.
