Research on software, computational engineering, and V&V technology for space systems
The objective of this research is to establish the systems engineering which balances mission success with reduction of development costs, by researching, development and utilization of the world's top-level information technology and computational engineering.
This will make possible a space mission that currently seems infeasible in terms of development costs and lead time.
Research on transportation technology
This project will research and develop basic technologies such as Liquefied Natural Gas (LNG) engines and thermal protection technologies to quickly acquire the bottleneck technologies essential to realize an innovative space transportation system.
Research on the technology of space systems
We will study various concepts of the space system, together with scientific expertise and technological capabilities in cooperation with internal and external bodies. Based on this study, we will propose a project that can pave the way to technologies that enhance Japan's competitiveness, provide solutions to societal challenges, and enable strategies to secure industrial growth in the decades to come.
Research on Earth observation sensor system
Utilizing comprehensive design engineering JAXA has acquired and accumulated for a sensor system, we have been researching key technologies and sensor systems expected to be required in the next decade or two. We have also been working with internal and external organizations to devise space missions that can fully benefit from the remote sensors to be developed in the future.
Research on space-qualified parts
We have been researching and developing space-qualified parts essential to satellite development with two objectives: maintaining independent space programs and placing Japan's future satellites in a more competitive position.
Our scientists work to identify promising domestic technologies and focus our resources on the development of parts that we expect to provide innovative, effective solutions for future satellite systems. We intend to better translate our research into practical outcomes at the earliest stage possible.
Ensuring the safety of space missions now and in the future
To ensure the safety of space activities and promote sustainable space development in the future, JAXA is strengthening its cooperation with the government, as well as with internal and external related organizations, and is engaged in research and development of space debris.
Advancement of basic technologies on mechanisms and materials for expanding space activities
To enable more flexible, extensive, and long-term space activities, we aim to establish technologies for accurately measuring and predicting the space environment, as well as basic technologies on materials, mechanisms, and structures that can apply to severe environments and commonly used equipment, such as batteries and attitude control actuators.

Innovative satellite technology demonstration program
This program is part of the basic plan for space policy to realize a comprehensive industrial base in outer space to provide opportunities to demonstrate equipment, parts, microsatellites and CubeSats developed by private companies, universities, research institutions, etc.
Cooperative Action Leading to Launcher Innovation for Stage Toss-back Operation (CALLISTO) project
We are engaged with research that aims to reuse the first stages of launch vehicles that previously have been disposable, as a method for securing further low costs and international competitiveness towards the realization of next generation of H3 launch vehicle.
While taking initiatives in technologies in which Japan has unique superiority, we also plan to proceed with efficient flight tests, based on international cooperation with French and German space agencies.
Development of SOI-SOC MPU
JAXA are developing SOI-SOC MPU as the high-functionality/high-performance next-generation MPU, which adopts the SOI(Silicon on Insulator)semiconductor manufacturing technology and the SOC (System on Chip) design technology. Since the SOI technology is fundamentally superior in radiation tolerance and the SOC technology can load multiple functions on a single chip, SOI-SOC MPU will contribute to diverse and sophisticated space missions.
