Space Transportation will be Realized by the Private Sector

The space industry will become one of the pillars of the Japanese economy.

The rockets developed in the 20th century have been innovated to carry more people and goods into space by combining the technologies that were possible at that time. However, most of them were "disposable" and carried goods and people at enormous cost, which was the norm in the world.

In recent years, as more players enter the space industry and business becomes more active with satellites that send data to Earth in space and large modules that can make products that can only be tested and manufactured in zero-gravity space, demand will arise for more frequent, lower cost transportation of large numbers of people and large cargoes. We expect that the demand for transportation of large numbers of people and large cargoes will increase with higher frequency and at lower cost.

So how can we transport larger quantities of goods and people at a lower cost?

The key word is "reuse" of rockets. A rocket normally carries the object to be carried into space on the tip of the rocket, which is then carried into space in a multi-stage rocket. This rocket itself is not destroyed and can be landed in place and used for the next flight. These efforts are made possible not only by personnel with experience in aerospace development who develop rockets, but also by combining computer power, which has developed rapidly in recent years, along with personnel from a wide range of backgrounds.

However, we believe that further technological innovation is the key to realizing a world in which space business and life are truly accessible.

We must comprehensively examine and create innovations in high-efficiency and high-performance propulsion systems, cost reductions through downsizing and weight reduction, and operational mechanisms that enable safe re-use and extended life of these systems. I am convinced that these are not things that can be completed by rocket engineers alone, but must be built by gathering people from various fields and sharing knowledge with them.

Space Transportation will be Realized by the Private Sector

The core of the business we are now trying to address in the last five years is the idea of a single stage space reusable (Single Stage To Orbit).

From launch to arrival in space, the rocket arrives without detachment, separates cargo and people, and returns to the ground in its original state.

This will enable us to reduce the cost per rocket launch to the limit, and we plan to build a business that can handle high-speed transportation between two points, space travel, and low earth orbit satellite launch missions. We will concentrate our management resources on the development of this rocket for the next five years, while building a foundation that will enable companies and individuals to do business in space on the basis of this rocket.

The Future of the Space Industry and Our Goals

Space development is no longer a dream but a goal. space utilization business is attracting attention as the next growth market after the it industry in the world.
The Transportation System We Aim for

The Transportation System We Aim for

Single Stage to Orbit (SSTO) refers to a space vehicle that consumes only fuel and propellant and can reach a satellite orbit without detaching the engine, fuel tank, and other components of the vehicle. The development of this single-stage rocket will be extremely important to achieving our vision. The reason for this is that it can lead to the effect of reducing rocket launch costs through the reuse of airframe parts. The oxygen-laden tanks used as fuel to fly in a vacuum, although expensive, are detached mid-flight and disposable as they are, as a means of reducing the weight of the vehicle to reach outer space. However, if a single-stage rocket can be developed that does not require the detachment of a part of the rocket body to reach space, the problem of redevelopment costs for expensive parts can be solved, and further investment in space projects, more frequent launch tests, and lower-cost rocket launches can be realized. This will lead to further investment in the space business, more frequent rocket launch experiments, and a future in which the private sector can go into space at low cost. The realization of a single-stage, high-frequency reusablerocket will be a great challenge for the Japanese space industry.
Building a Space Transportation Platform is a Mixed Martial Art

Building a Space Transportation Platform is a Mixed Martial Art

A high-frequency transport system for people and goods cannot be realized by developing only a high-frequency single-stage transport aircraft. It is necessary to have a launch site that can safely launch and land, and a ground platform that manages and controls the launch site to smoothly check, maintain, and re-launch the transporter. Repeated launch experiments are extremely costly and time-consuming in the research and development of new transport concepts. By combining simulations using computing power and data that can be obtained from experiments, we aim to create an efficient R&D system similar to agile development in the construction of IT systems. Also, in the manufacturing stage of the transport aircraft, we are considering a system in which the R&D team, the manufacturing team, and suppliers can constantly share information to enable efficient and high-speed manufacturing, such as by building a more efficient supply chain and providing feedback for improvement using data that can be obtained from the components. In order to realize these goals, we believe it is necessary to bring together the wisdom and experience of not only engineers who have built their careers in the aerospace industry, but also those from various manufacturing and IT industries, and to foster a corporate culture that is not bound by conventional wisdom.
