New Delhi: History created by ISRO today as it launches its smallest rocket at space. Indian Space Agency ISRO created a new history today. Indian Space Research Organization (ISRO) has launched its first Small Satellite Launch Vehicle (SSLV) rocket from Sriharikota. ISRO scientists and experts were engaged for the last several weeks for this mission. SSLV will be used for the first time to send satellites. Earlier, satellites were launched from PSLV and GSLV (Polar Satellite and Geosynchronous Launch Vehicle) rockets.

With the help of this rocket, ISRO will be able to send satellites up to 500 kg on the lower orbit (up to 500 km above the Earth) in a very less time and cost. In this mission, ISRO is sending two satellites Earth Observation Satellite- 02 and AzadiSat. The five-hour countdown began at 04:18 am on Sunday and was launched at 09:18 am from the Satish Dhawan Space Center in Sriharikota. However, in other missions, the countdown is 25 hours. After 13 minutes of launch, EOS-02 and then AzadiSat will be placed on the orbit path.

The ‘Azadi set’ produced by 750 students was also launched. Let us tell you that the SSLV satellite is also carrying an infrared camera with six meter resolution. On it is also an eight kg Azadi Sat satellite built by 750 students of government schools run by SpaceKidz India. According to SpaceKidz India, the significance of this project is that it has been built under the Amrit Mahotsav of Independence on the occasion of the 75th anniversary of Independence.

This is the country’s first small satellite launch vehicle. Earlier, small satellites depended on PSLV for Sun Synchronous Orbit, while larger missions used GSLV and GSLV Mark 3 for Geosynchronous Orbit. While it takes two to three months to bring and assemble the PSLV to the launch pad, the SSLV can be assembled within just 24 to 72 hours.

Also, it is designed in such a way that it can be launched anytime and anywhere, whether it is loading behind the track or launching it on a mobile launch vehicle or any ready made launch pad. have to launch.

With the arrival of SSLV, the number of launches will increase, we will be able to launch more satellites than before, due to which India will make a new identity in the commercial market as well, as well as there will be a lot of profit in terms of revenue. With this micro, nano or any satellite weighing less than 500 kg can be sent. Earlier PSLV was also used for these. Now SSLV will also be cheaper than PSLV and will reduce the existing load on PSLV.

SSLV: Can carry a payload of 10 kg to 500 kg to a planar orbit of 500 km.
PSLV: Can carry a payload of up to 1750 kg, to Sun Synchronous Orbit.
GSLV: Can carry a payload of 2500 kg up to Geosynchronous Orbit and 5000 kg to Lower Earth Orbit.
GSLV Mark3: Can carry a payload of 4000 kg up to Geosynchronous Orbit and 8000 kg payload up to Lower Earth Orbit.

EOS-02 is the primary satellite of this mission. This satellite is equipped with new technology and infrared camera which will work in areas like mapping, forestry, agriculture, geology and hydrology. Apart from this, it will be used for the defense sector.

AzadiSat is the second satellite of this mission, which will be placed in its orbit after separating it from the mission of EOS 02. Just before the Independence Day, this Azadi Sat has been prepared by the students of rural areas under the supervision of scientists. These students are associated with Space Kids India. It has a total of 75 different payloads weighing 50 grams.
