What kind of company is Rocket Link Technology Inc.?

It is a startup company aiming to reduce the cost and increase the frequency of space transportation services, developing innovative low-melting-point thermoplastic propellant (LTP).

What is the LTP fuel under development?

Unlike traditional thermosetting resins, it is a solid fuel that can be reversibly molded by cooling. It is easy to refill, repair, and reuse, significantly reducing manufacturing costs and time.

What are the main milestones announced in this release?

Within one year, they plan to conduct a practical observation rocket flight test using LTP, aiming to reach the mesosphere and outer space.

How much funding has been raised so far?

As of this release, they have secured a total of 2.45 billion yen in funding, including equity financing, government grants, and contract orders.

Can you tell me about the rocket manufacturing setup?

Considering manufacturability, they are manufacturing through general manufacturers rather than specialized space manufacturers.

Space startup Rocket Link Technology announced an accelerated development plan for its space transport service using its innovative Low Melting Temperature Thermoplastic Propellant (LTP), aiming for a flight test within a year.

Rocket Link Technology, Co., Ltd. (President and CEO: Yasuhiro Morita) has released an accelerated development plan to realize its space transport service.

The company aims to reduce costs and increase the frequency of space transport through the development of its innovative solid rocket fuel, LTP (Low Melting Temperature Thermoplastic Propellant). Based on the progress of LTP development and successful ground combustion tests, the company aims to reach the mesosphere and space within one year by conducting a practical sounding rocket-class flight test, as one of the staged demonstration tests toward service realization around 2030.

As of this release, the cumulative funding amount has reached 2.45 billion JPY.

Characteristics of LTP Conventional solid fuels use thermosetting resins, requiring precise manufacturing processes taking 2-3 weeks. In contrast, LTP allows for reversible molding via natural cooling, enabling short-time production, refilling, repair, and reuse of propellants. Consequently, it can be manufactured not only by specialized manufacturers but also by general manufacturers.

Overview of Flight Test Having already succeeded in a 5km altitude test with a 135mm diameter rocket, this test will apply the propellant to a practical sounding rocket-class motor to reach space.
