Major Research and Development

JAXA has launched for deep space exploration the project for development and operation of new antenna and ground station with expanded capacity.

A huge balloon is a flying object for scientific observations and space engineering tests in the same manner as satellites and sounding rockets.

Studying planets and the moon leads us to understand the birth of the Earth and the origin of the solar system and life. Observing planets and the moon through various methods and analyzing acquired data from every angle are imperative for these studies.

Capturing phenomena in the solar system and planets beyond it and their surrounding area provides us with clues to solve the mysteries of space. Therefore, it is essential to acquire as much information as possible by seizing various radio waves including X-rays, infrared lights and plasmas in addition to visible lights.

JAXA promotes space engineering research to stably perform space exploration activities “further”, “with more flexibility” and “in wider directions.”
Astronomical Observation Satellites
Latter Phase In Operation

World’s first space telescope to observe planets!

The HINODE, an observatory satellite to study the impact of the Sun on the Earth High expectations for new solar observations through international efforts by the United Kingdom, the United States and Japan

Cutting-edge small satellite developed in-house

To elucidate high-energy electrons that repeat their generation and disappearance.
Under Development
