An Indian rocket named Polar Satellite Launch Vehicle (PSLV) on Wednesday morning lifted off successfully with the country’s earth observation satellite Cartosat, Google company Terra Bella’s SkySat Gen2-1 and 18 other satellites.

The PSLV rocket standing 44.4 metre tall and weighing 320 tonne, tore into the morning skies at 9.26am with a growl breaking free of the earth’s gravitational pull.

The 20 satellites weighed 1,288 kg.

The rocket’s main cargo is India’s 725.5 kg Cartosat-2 series satellite for earth observation.

This satellite is similar to the earlier Cartosat-2, 2A and 2B.

The other 19 satellites weighing totally around 560 kg are from US, Canada, Germany and Indonesia as well as one satellite each from Chennai’s Sathyabama University and College of Engineering, Pune.

The whole launch mission will get over in around 26 minutes.

The images sent by Cartosat satellite will be useful for cartographic, urban, rural, coastal land use, water distribution and other applications.

According to Isro, the 110 kg SkySat Gen2-1 belonging to Terra Bella, a Google company is a small earth imaging satellite capable of capturing sub-metre resolution imagery and high definition video.

The Planet Lab’s Dove Satellites are also earth imaging satellites. A total of 12 Dove satellites each weighing 4.7 kg are carried in this mission inside three QuadPack dispensers, Isro said.

The PSLV rocket also carries 85 kg M3MSat from Canada. The technology demonstration mission is jointly funded and managed by Defence Research and Development Canada and the Canadian Space Agency.

The other foreign satellites on board are: 120 kg LAPSN-A3 of Indonesia, the 130 kg BIROS, from German Aerospace Centre, Germany and the 25.5 kg GHGSat-D, Canada.

On the other hand, the 1.5 kg Sathyabamasat from Sathyabama University will collect data on green house gases while the 1 kg Swayam satellite from College of Engineering, Pune will provide point-to-point messaging services to the HAM radio community.

Wednesday’s mission will be the first time the Isro is launching more the 10 satellites with a single rocket.

In 2008, the Isro had launched 10 satellites with the PSLV rocket.

Till date India has launched 57 foreign satellites successfully.

Here are some essential facts about the historic launch:

1. India is now the third nation to launch multiple satellites in one go – after Russia and the United States, who have previously launched 37 and 30 satellites, respectively.

2. In 2008, ISRO sent out 10 satellites in a single launch. On 28 April 2008, ISRO launched a Remote Sensing satellite CARTOSAT-2A along with Indian Mini Satellite (IMS-1) and eight nanosatellites.

3. Once the PSLV C-34 takes off from the Satish Dhawan Space Centre, all 20 satellites will be launched into a 505 km polar Sun Synchronous Orbit, 26 minutes after take-off. 16 minutes after take-off, the first satellite will be injected into orbit, followed by the next 19 satellites, which will be set into orbit within the next 10 minutes.

4. The total weight of all the 20 satellites is about 1,288 kg.

5. The Cartosat-2, 2A and 2B satellites are a series of satellites that are intended to send back imagery that would be used for cartographic applications, and other Land Information System and Geographical Information System applications.

6. Satellites from Indonesia, US, Canada and Germany are among the 20 satellites being sent into orbit.

6. Satellites from Indonesia, US, Canada and Germany are among the 20 satellites being sent into orbit.

7. The LAPAN-A3 from Indonesia, M3MSat and GHGSat-D from Canada, BIROS from Germany and SkySat Gen2-1 & Dove Satellites from USA, will be used for a variety of purposes like remote sensing of high temperature events, measuring the atmospheric concentration of greenhouse gases and capturing sub-meter resolution imagery.

8. Satellites from two Indian universities are also among the 20. While the Swayam satellite from the College of Engineering, Pune, is aimed at providing point-to-point messaging services to the HAM (amateur radio) community, the Sathyabamasat satellite from the Sathyabama University Chennai will help collect data on green house gases.
