PSLV-C34

PSLV-C34 was the 36th mission of the PSLV (Polar Satellite Launch Vehicle) program and 14th mission of PSLV in XL configuration. The PSLV-C34 successfully carried and deployed 20 satellites in the Sun-synchronous orbit. With a launch mass of 320,000 kilograms (710,000 lb) and payload mass of 1,288 kilograms (2,840 lb), the C34 set a new record of deploying the maximum number of satellites by Indian Space Research Organisation in a single mission. The PSLV-C34 carried One Cartosat-2 satellite, SathyabamaSat (satellite from Sathyabama University, Chennai), Swayam (satellite from College of Engineering, Pune) & 17 other satellites from United States, Canada, Germany & Indonesia.^{[1][2][3][4][5][6]}

Launch

PSLV-C34 was launched from Satish Dhawan Space Centre at 09:26 IST on 22 June 2016. The PSLV carried total 20 satellites including the primary payload Cartosat-2C. Cartosat-2C was placed in low Earth orbit at 9:44 IST. The entire mission lasted 26 minutes and 30 seconds.^{[1][2][3][4][5][6]} The PSLV-C34 is a more advanced, expendable version of the rocket used to launch the Indian Mars Orbiter in 2014.^[8]

Mission milestones

The mission marked:

• 36th flight of Polar Satellite Launch Vehicle.
• 14th flight of Polar Satellite Launch Vehicle in XL configuration.
• Record number of satellites carried on a single flight by ISRO.

Record launch

On 28 April 2008, by placing 10 satellites on PSLV-C9 (PSLV-CA), Indian Space Research Organisation created a world record for the highest number of satellites launched in a single mission. This record was broken by NASA in 2013 (by launching 29 satellites) and was further improved by ISRO when they launched 104 satellites. PSLV-C34 launch was the biggest launch (in terms of number of satellites) by ISRO until PSLV-C37.^[9][10]
