European Space Research Organisation

Flight record

Counts are launches filed under ESRO’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. ESRO is counted below in whichever role the current manifest actually gives it.

No scheduled flight in the current window names ESRO 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 ESRO

The European Space Research Organisation (ESRO) was an international organisation founded by 10 European nations with the intention of jointly pursuing scientific research in space. It was founded in 1964. As an organisation ESRO was based on a previously existing international scientific institution, CERN. The ESRO convention, the organisations founding document outlines it as an entity exclusively devoted to scientific pursuits. This was the case for most of its lifetime but in the final years before the formation of ESA, the European Space Agency, ESRO began a programme in the field of telecommunications.

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 European Space Research Organisation flown?

European Space Research Organisation has 5 launches on record under its own name, of which 4 succeeded and 1 failed. The register counts launches flown under an operator's own name, not missions or payloads it contributed to.

What is European Space Research Organisation's success rate?

European Space Research Organisation has a lifetime launch success rate of 80.0%, calculated as 4 successful flights out of 5 attempts. Its current run is 4 consecutive successes.

When is European Space Research Organisation's next launch?

European Space Research Organisation is not flying anything inside Delta-V's current manifest window, which reaches to 2026-12-31 00:00:00Z.

Does European Space Research Organisation fly its own rockets, or buy launches from another operator?

European Space Research Organisation has 5 launches flown under its own name in the launch register. It is not the operator on any flight 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 European Space Research Organisation based?

European Space Research Organisation is based in France and the register classifies it as a multinational operator. It was founded in 1964.
