ISRO Set to Create Record Launch of 103 Satellites in One Go

Indian Space Research Organisation is all set to send a record 103 satellites into space, breaking the Russian record of 37 satellites launched in June 2014. To be launched in a staggered separation of angles, velocities and orientations, 100 of these satellites are foreign and three are Indian.

Dr K. Sivan, Director of the Vikram Sarabhai Space Centre told media that the satellites will be launched at a “relative velocity of 1 m/s” to the launch vehicle and even a one degree separation angle is enough to avoid any collision of satellites.

The satellites will be lofted off in their respective orbits at a height of 500 km from the Earth, where the launch vehicle requires 90 minutes to finish one orbit around the Earth. The time period is ample enough to launch all 103 satellites, Said Dr Sivan.

ISRO’s workhorse PSLV will break the past record set by a Russian Dnepr rocket launched on June 19, 2014 setting a record-breaking 37 satellites in their orbits.

Prior to that, American private firm Antares had held the record of launching 34 satellites in January 2014. Otherwise, Dnepr had owned the record of 33 satellites launch. In fact, Dnepr record set in 2007 was in vogue until November 2013 when the US Minotaur I broke it.

Here is the timeline of maximum number of satellites launched per rocket:

April 17, 2007: Russo-Ukrainian Dnepr placed 14 satellites into low Earth orbit, a year after it failed to loft off 18 satellites. The record was broken only in 2013.

November 19, 2013: Orbital’s Minotaur I, as part of the ORS-3 mission, lofted a record 29 satellites.

November 21, 2013: Russian Dnepr rocket launched 33 satellites breaking the US record in just one day after.

January 9, 2014: US firm Orbital’s Antares rocket launched 34 satellites as part of its first Commercial Resupply for the ISS.

June 19, 2014: Russian Dnepr rocket, converted from an ICBM, launched 37 satellites in one go.

February 2014: Indian Space Research Organisation is all set to launch 103 satellites at one go breaking the century barrier altogether.

The launchpad in Sriharikota is all set for the launch of PSLV C-37 that will carry a record 103 satellites in the first week of February (SDSC SHAR)
