ISRO's first SSLV mission fails, satellites placed in wrong orbit
Tags: Science and Technology
The Indian Space Research Organization (ISRO) on 7 August placed its first Small Satellite Launch Vehicle (SSLV) satellites in the wrong orbit.
After this the earth observation satellite and AzadiSat satellite are “no longer usable”.
SSLV has placed the satellites on an elliptical orbit instead of a circular one.
When satellites are placed in such an orbit, they cannot stay there for long and come down.
SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit.
The space agency said a committee would analyze why it failed and ISRO would soon be back with SSLV-D2.
SSLV had suffered 'data loss' in its terminal phase, after performing "as expected" in all phases.
Earth observation satellite EOS-02 and co-passenger student satellite AzadiSat are important payloads for SSLV.
EOS-02 is an experimental optical remote sensing satellite and has high spatial resolution.
It aims to realize and fly an experimental imaging satellite with a short turnaround time and demonstrate launch-on-demand capability.
EOS-02 belongs to the family of microsatellite series of spacecraft.
It is a 8U CubeSat weighing around 8 kilograms.
It carries 75 different types of payloads each weighing around 50 grams.
The Guidance for manufacturing these payloads was provided to girl students from rural areas of India.
The payload has been integrated by the student team of 'Space Kidz India'.
The ground system developed by 'Space Kids India' will be used to receive data from this satellite.
What is SSLV?
The Small Satellite Launch Vehicle (SSLV) is 34 metres long, which is about 10 metres less than PSLV.
Its vehicle diameter is two metres as compared to PSLV's 2.8 metres.
Objectives of SSLV
To provide inputs on thermal anomalies for ancillary applications in the fields of geo-environmental studies, forestry, hydrology, agriculture, soil and coastal studies etc.
To create greater synergy between the government space sector and private Indian industries and institutions.
