ISRO hits a century: 100th satellite launched today

The Indian Space Research Organisation has successfully launched its 100th satellite PSLV-C4/CARTOSTAT-2 series at 9:28 am on Friday from Satish Dhawan Space Centre, Sriharikota along with 30 co-passengers at liftoff.
Having placed more than 250 satellites in orbits through Polar Satellite Launch Vehicle (PSLV), this will be the 7th remote sensing satellite in the ‘CARTOSTAT-2’ series to be placed in the sun-synchronous orbit. The 100 kg Indian microsatellite will be able to capture images at night while monitoring the rural and urban landscape, coastal land use regulation, detecting changes in the geographical features and creation of land use maps.
Today’s launch will be historical for 3 reasons. It will be ISRO’s 100th satellite launch. ISRO is once again attempting the tricky multiple burn technology where the fourth stage engine will be ignited and shut off four times to place 31 satellites in different orbits including its main payload, CARTOSTAT-2S, and 30 foreign satellites within a period of 42 minutes into polar sun-synchronous orbit at an altitude of 505 KM. And most importantly, ISRO will re-enter the race after the major setback suffered on August 31, 2017, as the PSLV failed to enter the orbit due to heat shield malfunction.
The mission has launched satellites from six other countries: Canada, Finland, Republic of Korea, France, The UK, and the US. The multiple burn technology as demonstrated earlier by ISRO will prove to be a cost-effective technique to launch more commercial satellites.
