New Delhi: The Indian Space Research Organization (ISRO) is on the verge of creating history as the space agency is all set to launch its maiden mission. SSLV The mission, carrying an Earth observation satellite and a student satellite, took off from the space center at Sriharikota, about 135 km from here, on Sunday.
Having made a place on successful mission launches via its reliable workhorse Polar Satellite Launch Vehicles (PSLV), Geosynchronous Launch Vehicle (GSLV), ISRO is making its first launch of a Small Satellite Launch Vehicle (SSLV) which will be used to deploy satellites in low Earth orbit.
ISRO scientists have been developing small launch vehicles over the past few weeks to meet the demand for smaller satellites that weigh up to 500 kg and can be injected into a 500-km low Earth orbit.
The SSLV is 34 meters long, about 10 meters shorter than PSLV and has a vehicle diameter of two meters as compared to PSLV’s 2.8 metres.
The lift-off mass of the SSLV is 120 tonnes while the PSLV has 320 tonnes, which can carry a payload of up to 1,800 kg.
In Sunday’s mission, the SSLV will be carrying Earth Observation Satellite-02 and a co-passenger satellite AzadiSat – developed by the student team of ‘Space Kidz India’.
According to ISRO sources, the countdown which will be 25 hours as compared to other missions has been reduced to five hours and will begin at 4.18 am for lift-off from the first launch pad of the Satish Dhawan Space Center at 9.18 am on Sunday. was expected. Sriharikota.
The importance of SSLV is that it has a fourth stage which is based on liquid propulsion. Velocity Trimming Module To place the satellites in the desired orbit. The rocket includes solid fuel to fire the first three stages.
The Earth observation satellite, designed by ISRO, provides advanced optical remote sensing operating in the infra-red band with high spatial resolution. It belongs to the micro satellite series of spacecraft.
After a journey of about 13 minutes, the SSLV is expected to first place the EOS-02 into the intended orbit, followed by AzadiSat, an eight kg CubeSat, which is being used by girl students of government schools across the country to mark the 75th anniversary of independence. designed on.
ISRO said, SSLV offers short turn-around time, flexibility in accommodating multiple satellites, on-demand feasibility and minimal launch infrastructure requirements.
Azadisat carries 75 different payloads, each weighing around 50 grams. Girl students from rural areas across the country were guided by ISRO scientists to build these payloads, which are integrated by the student team of ‘Space Kids India’.
The ground system developed by Space Kidz India will be used to receive data from this satellite. ISRO began launching sounding rockets in 1965 to investigate the upper atmospheric regions and for space research. The first sounding rocket was launched near Thiruvananthapuram in November 1963. The space agency later launched the country’s first Satellite Launch Vehicle-3 in 1980, which can carry a payload of up to 40 kg. In 1987, ISRO conducted the first developmental flight of the Augmented Satellite Launch Vehicle (ASLV) with a payload capacity of up to 150kgs. Later ISRO built its first Polar Satellite Launch Vehicle in September 1993, which was unsuccessful. However in 1994, ISRO tasted success on its first successful launch as it emerged as a reliable and versatile dependable workhorse. ISRO conducted the first flight of the Geosynchronous Satellite Launch Vehicle in 2001, the largest launch vehicle developed by India, which is currently in operation. The lift-off mass of GSLV is 414.75 tonnes.
