The much laudable ISRO's task of launching a record-breaking 104 satellites in one go using its workhorse PSLV-C37 in the first week of February has been making headlines for a couple of weeks now.

"We are making a century by launching over 100 satellites at one go," said S Somnath, Director of the Liquid Propulsion Systems Centre of the ISRO.

#ISRO to launch 103 satellites on a single #PSLVC37 rocket, know how all the satellites will be placed in #orbit https://t.co/cC2r0hXXkq pic.twitter.com/iCeOa5xkAt — News Nation (@NewsNationTV) January 22, 2017

The space agency had earlier planned a launch of 83 satellites in the last week of January, of which 80 were foreign ones.

But with the addition of 20 more foreign satellites, the launch was delayed by a week and will now take place in the first week of February, Somnath said. Let's look at the launch in detail:

#1 ISRO will launch 104 satellites into orbit on its PSLV-C37 rocket on February 15.

#2 Out of 104, 88 will be from the US.

They weigh around 5 kg each and are called ‘Doves’ or Flock 3p.

#3 No space agency has launched such a large number of satellites in a single flight so far.

Prior to this Russia’s Dnepr launcher holds the record for lifting 37 satellites to orbit in June 2014, followed by ISRO’s PSLV that launched 20 satellites last year,

#4 The PSLV will also carry a main remote-sensing satellite in the Cartosat-2 series and two small spacecraft.

#5 Yes, only 3 of these will be Indian satellites.

Apart from the US and India, Germany is participating in this launch too.

The launch will be a major feat in country's space history as no exercise on this scale has been attempted before. Since September 2015, the PSLV has launched 18 small US earth imaging satellites and in a total of 79 foreign spacecraft — which earns it some revenue and an increasingly global market share.
