Counts are launches filed under ISRO’s own name in The Space Devs’ Launch Library register. They are not a count of missions or payloads: a spacecraft that flew on a contracted vehicle is credited to the operator that flew it.

Who flies for them, and who they fly for

An operator owns the rocket and runs the count, and it is the operator’s name the launch schedule filters by. A customer funds the mission, supplies the payload and buys the ride. Plenty of organisations are both. ISRO is counted below in whichever role the current manifest actually gives it.

No scheduled flight in the current window names ISRO while being operated by somebody else.

How this is counted: a scheduled launch is treated as a customer flight when this organisation’s name or abbreviation appears in the launch name, mission name or programme and somebody else is flying it. Mission descriptions are not searched, and the window is one batch of the next launches worldwide, reaching to 2026-12-31 00:00:00Z — so both counts are a floor, not a complete manifest.

About ISRO

The Indian Space Research Organisation (ISRO) is the space agency of the Government of India headquartered in the city of Bangalore. Its vision is to "harness space technology for national development while pursuing space science research and planetary exploration."

Upcoming launches

“T-0 known to” is the register’s own precision on the launch time — a date good only to the month is shown as such rather than counted down as if it were exact. A go-probability appears only where the operator published one for that flight; Delta-V does not calculate it and it is not a forecast made here.

Common questions

How many launches has Indian Space Research Organization flown?
Indian Space Research Organization has 100 launches on record under its own name, of which 85 succeeded and 15 failed. The register counts launches flown under an operator's own name, not missions or payloads it contributed to.
What is Indian Space Research Organization's success rate?
Indian Space Research Organization has a lifetime launch success rate of 85.0%, calculated as 85 successful flights out of 100 attempts. Its current run is 1 consecutive successes.
When is Indian Space Research Organization's next launch?
Indian Space Research Organization's next launch inside Delta-V's manifest window is GSLV Mk II | IRNSS-1L (NVS-03), scheduled for 2026-10-31 00:00:00Z from Satish Dhawan Space Centre Second Launch Pad. The register files that time with a precision of M. A launch time is a no-earlier-than target and can move.
Does Indian Space Research Organization fly its own rockets, or buy launches from another operator?
Indian Space Research Organization has 100 launches flown under its own name in the launch register. It is the operator on 5 flights in the current manifest window. An operator owns the rocket and runs the count; a customer funds the mission, supplies the payload and buys the ride. The operator filter on the launch schedule lists only the former, which is why a well-known agency can be central to a flight and still not appear on it.
Where is Indian Space Research Organization based?
Indian Space Research Organization is based in India and the register classifies it as a government operator. It was founded in 1969.
