SRIHARIKOTA: India scripted a new chapter in the history of space exploration on Wednesday with the successful launch of a record 104 satellites by Isro’s Polar Satellite Launch Vehicle (PSLV) in a single mission.
PSLV-C37 carrying the 104 satellites lifted off from the first launch pad at Satish Dhawan Space Centre in Sriharikota at 9.28am. It was PSLV’s 39th flight.
Seventeen minutes later, the rocket started placing the satellites into orbit, one by one with a time-frame of about 11 minutes.
Out of the total 104 satellites placed in orbit, 101 satellites belonged to six foreign countries. They included 96 from the US and one each from Israel, the UAE, the Netherlands, Switzerland and Kazakhstan.
PSLV first injected its main payload Cartosat- 2 series, India’s indigenously built earth observation satellite. It was followed by two other nanosatellites of Isro —- INS-1A and INS-1B.
It then took less than 10 minutes for the rocket to spew out 101 passengers, which are all foreign nanosatellites, as it travelled up in altitude reaching the polar sun synchronous orbit.
Russian Space Agency held a record of launching 37 satellites in one go during its mission in June 2014. India previously launched 23 satellites in a single mission in June 2015.
Equipped with panchromatic and multispectral cameras, the 664kg Cartosat -2 will provide remote sensing services similar to that of its predecessors.
Images from the satellite will be used for cartographic applications, urban and rural applications, coastal land use and regulation, utility management like road network monitoring, water distribution, creation of land use maps, change detection to bring out geographical and manmade features and various other land information system (LIS) and geographical information system (GSI) applications.
INS-1A and INS-1B are versatile and modular nanosatellite bus system envisioned for future science and experimental payload.
Among the foreign satellites, 88 cube satellites belonged to San Francisco-based earth imaging startup Planet. With the launch, the company has increased its fleet to 143 satellites which will soon begin capturing images of the earth’s entire landmass, including India, every day.
Eight other satellites belonging to Spire Global, US, will provide services for vessel tracking and weather measurement.
The nanosatellites from Israel, Kazakhstan, the Netherlands, Switzerland and the UAE are mostly technology demonstrators.
