ISRO 100th satellite launch from Sriharikota: ISRO has made India proud again. The space agency successfully launched its 100th satellite ‘Cartosat-2 Series’ from Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota Island on Friday. For the mission, the Indian Space Research Organisation used PSLV-C40 launch vehicle. It is carrying 31 satellites, including three from India and 28 from six other countries. The weather observation ‘Cartosat-2 Series’ satellite and 29 others were inserted into a 505-kilometre sun-synchronous orbit after about seventeen and a half minutes since its liftoff. Later, the payload Microsat developed by the ISRO will be taken down to a lower orbit at 359-kilometre height and launched using the ‘multiple engine switch-on’ method.
ISRO 100th satellite launch: Here is all you want to know
This satellite is the seventh remote sensing satellite in its series and has the mission life of five years.
Its uses include monitoring urban and rural applications, coastal land use regulation, managing services like road networks and water distribution, detecting changes in geographical features and creation of land use maps.
The flight is the first since the setback suffered by the PSLV in August last and is set to demonstrate that the workhorse rocket is back in the game for reliable satellite launches in the low earth and polar orbits.
The 44.4-metre tall Polar Satellite Launch Vehicle (PSLV-C40) roared into a clear sky after a perfect lift-off at 9.29 a.m. following a 28-hour countdown.
The 320-tonne rocket would eject the satellites one-by-one and deploy them into the earth’s lower orbit 17 minutes and 18 seconds after the lift-off.
The spaceport is about 80 km northeast of Chennai off the Bay of Bengal coast.
Of the 31 satellites, three are Indian and the rest are from Canada, Finland, France, South Korea, UK and the US.
The Indian satellites include the 710 kg Cartosat-2 series for Earth observation as the primary satellite of the mission, along with co-passenger payloads, including 100 kg micro satellite and a 10 kg nano satellite.
Cartosat-2 series was the first to be separated from the rocket and injected into the sun synchronous orbit at 505km above the earth, followed by the 10 kg nano satellite and the 100 kg micro-sat in different orbits.
The Cartosat-2 series would orbit around the Earth for five years.
The micro satellite would be India’s 100th satellite in space around the earth’s orbit.
The first space mission in 2018 came four months after a similar rocket failed to deliver the country’s eighth navigation satellite in the earth’s lower orbit on August 31, 2017.
