Interstellar Technologies

Flight record

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

No scheduled flight in the current window names ISTECH 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 ISTECH

Interstellar Technologies, Inc. (Japanese: インターステラテクノロジズ（株） Hepburn: Intāsutera Tekunorojizu (kabu)) is a Japanese NewSpace company. It is a rocket spacelaunch company developing the MOMO launcher. Its stated goal is to reduce the cost of access to space. In 2017, it became the first Japanese company to launch a privately developed space rocket, though the launch was unsuccessful. The company plans to complete a rocket by 2020 that would be capable of launching small satellites into orbit.

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 Interstellar Technologies flown?

Interstellar Technologies has 7 launches on record under its own name, of which 3 succeeded and 4 failed. The register counts launches flown under an operator's own name, not missions or payloads it contributed to.

What is Interstellar Technologies's success rate?

Interstellar Technologies has a lifetime launch success rate of 42.9%, calculated as 3 successful flights out of 7 attempts. Its current run is 2 consecutive successes.

When is Interstellar Technologies's next launch?

Interstellar Technologies is not flying anything inside Delta-V's current manifest window, which reaches to 2026-12-31 00:00:00Z. The register lists 1 scheduled launch under its own name, with dates further out or not yet filed.

Does Interstellar Technologies fly its own rockets, or buy launches from another operator?

Interstellar Technologies has 7 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 Interstellar Technologies based?

Interstellar Technologies is based in Japan and the register classifies it as a commercial operator. It was founded in 2005.
