The Indian Space Research Organisation (ISRO) just sent 20 satellites into orbit with one launch, marking the largest satellite launch in the space agency’s history.

Their previous record was 10 satellites delivered with one mission, and this latest accomplishment takes them a lot closer to the delivery rates of NASA and the Russian Federal Space Agency, solidifying India's place in the global space market.

Out of the 20 satellites, 17 were commercial, so used by companies to help us do things like get better TV signals or weather forecasts. The main cargo, though, was the ISRO’s 725.5-kilogram (1,599-pound) Cartosat-2 - a satellite used for earth observation much like NASA’s Landsat program.

"Each of these small objects that you are putting into space will carry out their own activity, which is independent of the other, and each of them will live a wonderful life for a finite period," ISRO chairman A. S. Kiran Kumar told NDTV.

Pulling off such a launch is no easy task. The satellites, which were launched from the island of Sriharikota, have to be 'injected' into orbit at the correct distance from one another to ensure they don’t eventually smash together.

"After each satellite is injected into orbit, the vehicle will be re-oriented if required and the next satellite will be put into orbit with a varying velocity so that the distance between the satellites grows monotonically," Vikram Sarabhai Space Centre director, K. Sivan, told T. S. Subramanian from The Hindu. "We will do this to ensure that there is no collision of satellites."

"Then, after a huge gap of 3,000 seconds, PS-4 [the fourth stage] will be re-ignited for 5 seconds," Sivan continued. "Then, it will be switched off for another 3,000 seconds. It will be re-ignited for another 5 seconds."

This is really big news for the ISRO for two reasons: it represents both the largest satellite launch in the agency’s history - putting them closer to NASA’s 2013 record of 29 and Russia’s 2014 record of 33 - and it shows that foreign companies are ready to pay the ISRO to launch satellites for them.

"India is attracting key foreign players, most importantly the US, in the space market thanks to its cost-effectiveness and credibility," said expert Ajay Lele, a senior fellow at New Delhi’s Institute for Defence Studies and Analyses, who was not a part of the launch team.

Most of those 'key foreign players' are from the US. In fact, 13 of the 20 satellites sent to orbit in this latest round were from US-based companies and organisations with a Google-owned company, Terra Bella, being one of them.

The other 7 satellites - minus the Cartosat-2 - were from Germany, Canada, and Indonesia, though the ISRO does not say how many are from each.

In total, the mission - called PSLV-C34 - sent roughly 1,288 kilograms (2,863 pounds) worth of satellites into Earth’s orbit, and, if history is anything to go off of, they probably did it for way less money than other agencies, but an exact number hasn’t been reported just yet.

Over the past few years, the ISRO has gained a reputation for frugality, especially since many of their missions are successful despite the cost-cutting. For example, in 2014, the ISRO sent an unmanned rocket to Mars that cost only US$73 million in total. Meanwhile, NASA’s Maven mission - the closest comparison to India’s rocket mission - cost over US$671 million.

Launching rockets on the cheap isn’t the only concern for the ISRO. Just last month, the agency tested an early version of a shuttle that they hope will offer a reusable way for astronauts to get to and from space, just like NASA’s Space Shuttle programme used to.

The ISRO is becoming a major player on the space front, joining the ranks of NASA, SpaceX, and Blue Origin. And that's great, because if there's one thing that's guaranteed to get us off this big blue rock faster, it's a little healthy competition. It'll be exciting to see what happens next.
