Rank 39 documents PSLV C37 — the 15 February 2017 flight that set the world record for most satellites deployed on a single rocket, placing 104 payloads into sun-synchronous orbit from Sriharikota aboard the workhorse PSLV-XL configuration with PSOM-XL strap-on boosters. Cartosat-2D served as primary payload while 103 secondary satellites — international cubesats and nanosats from commercial and academic customers — rode India's proven launcher in a single deployment sequence that demonstrated ISRO's rideshare economics and precise injection capability. The mission validated PSLV as a global smallsat taxi years before dedicated small launchers like SSLV entered service, earning ISRO commercial launch contracts and prestige in the NewSpace rideshare market.
