ISRO launches record breaking 20-in-1 PSLV mission

Today, ISRO has marked milestone in space science. Breaking the barriers ISRO has successfully launched PSLV-C34 carrying 20 satellites. This is the largest ever numbering in satellite launching.

The Launch

The launch was made from ISRO’s Satish Dhawan Space Centre in Sriharikota, Andra Pradesh. The PSLV C34 measuring 44.4 meters and weighing 320 tonne lift off at 9:26 am and it took approximately 25 minutes to complete its admission in space.

3 Indian Satellites

Cartosat-2 series satellite ( 727.5 kg, India)

Cartosat-2 is the main cargo of the mission. This satellite is similar to the Cartosat-2 , 2A, 2B satellites launched earlier. This earth observation satellite will send its captures which will be useful in cartographic applications, coastal land use and regulation, road networking, water management, creation and using of local maps, precision study, change detection geographical information.

Swayam (1kg, College of Engineering, Pune)

This Indian satellite provides Point-to-Point messaging service to the HAM community radio.

It is important to note that HAM radios played a vital role in saving lives while Chennai floods occurred.

Sathyabamasat (1.5 kg, Sathyabama University, Chennai)

This satellite aims to collect data on green house gases.

Foreign Satellites 

USA : 13 Satellites 

SkySat Gen2-1 (110 kg, USA)

SkySat Gen2-1 is built by Terra Bella – A Google company. This satellite can capture sub-meter resolution imagery and HD video of Earth.

Dove Satellites (12 Satellites each 4.7 kg, USA)

Planet lab’s satellites are packed in three containers each hold 4 satellites. These 12 Flock-2P are Earth imaging satellites.

2 from Canada

M3MSat (85 kg, Canada)

Maritime Monitoring and Messaging Micro-Satellite which is joint funded and managed by Defense Research and Development Canada (DRDC) and the Canadian Space Agency (CSA). This is a technology demonstration mission aimed at collection and study of Automatic Identification System signals from low-Earth orbit.

GHGSat-D (25.5 kg, Canada)

This Earth observation satellite collects data on atmospheric concentration of greenhouse gases (Carbon Dioxide and Methane). The satellite is built by Flight Laboratory of the University of Toronto Institute for Aerospace Studies.

Indonesia and Germany

LAPAN-A3 (120 kg, Indonesia)

This micro satellite is for earth observation. Main objective of this satellite is to observe land use and environment.

BIROS (130 kg, Germany)

Berlin Infrared Optical System (BIROS) is a micro satellite of German Aerospace Center.Its mission is the remote sensing of high temperature events.


  • Till now, ISRO has launched 74 satellites from about 20 countries, earning about $ 100 million.
  • This is the first time ISRO has launched more than 10 satellites with a single rocket.
  • The Mars Orbiter Mission is a world wonder that made cheap visit to mars than making a space science film.
  • ISRO’s Chandrayaan mission was the first to find water in lunar’s land.
