Institute of Space and Astronautical Science

Flight record

These are launches under ISAS’s own name in The Space Devs’ Launch Library. They don’t count missions or payloads. A spacecraft that flew on someone else’s rocket counts for the operator that flew it.

Operator or customer

An operator owns the rocket and runs the count, and the launch schedule filters by operator. A customer pays for the mission, supplies the payload and buys the ride. Some organisations are both. Below, ISAS is counted in whichever role the current schedule gives it.

No scheduled flight names ISAS with someone else flying it.

How we count it: a scheduled launch counts as a customer flight when this organisation’s name or abbreviation is in the launch name, mission name or programme, and someone else is flying it. We don’t search mission descriptions, and we only see the schedule as far as it goes, which is 2039-12-31 00:00:00Z. So treat both counts as a minimum.

About ISAS

ISAS is a Japanese national research organization of astrophysics using rockets, astronomical satellites and interplanetary probes which played a major role in Japan's space development.

Upcoming launches

The label on each flight says how exact its launch time is. If the date is only known to the month, you’ll see the month and no countdown. A weather go-probability only shows when Launch Library has one for that flight. EveryLaunch doesn’t work it out.

Common questions

How many launches has Institute of Space and Astronautical Science flown?

Institute of Space and Astronautical Science has flown 32 launches under its own name. 24 succeeded and 8 failed. That counts launches it flew itself, not missions or payloads it contributed to.

What is Institute of Space and Astronautical Science's success rate?

75.0%. That's 24 successful flights out of 32 attempts. Its last 1 launches in a row have succeeded.

When is Institute of Space and Astronautical Science's next launch?

Institute of Space and Astronautical Science has nothing on the schedule EveryLaunch can see, which runs to 2039-12-31 00:00:00Z.

Does Institute of Space and Astronautical Science fly its own rockets, or buy launches from another operator?

Institute of Space and Astronautical Science has flown 32 launches under its own name. It isn't the operator on any scheduled flight we can see. An operator owns the rocket and runs the count. A customer pays for the mission, supplies the payload and buys the ride. The operator filter on the launch schedule only lists operators, so a well-known agency can own a mission and still not show up there.

Where is Institute of Space and Astronautical Science based?

Japan. Launch Library lists it as a government operator.
