Space Science Research

The biggest challenges of space science are to reveal the mysteries of the structure and evolution of the universe, the processes of planet formation, and the origin of life.
Due to the progress of rocket and satellite technologies, space observations unhindered by the Earth’s atmosphere have become possible and X-ray and infrared astronomies have progressed rapidly. We have learnt about objects that used to be invisible. In addition, the history of the solar system is gradually being revealed through explorations of the Moon and planets. Space-based astronomical observations and planetary explorations have entered a mature phase.
We will continue further observations and research to investigate where mankind came from and where we are going, as well as investigate the past and future of the Earth.

Major Research and Development

GREAT, Ground Station for Deep Space Exploration and Telecommunication

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

Scientific Ballooning

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

Research on Lunar, Planetary Science

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.

Research on Space Plasma, X-Rays, and Infrared-Rays

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.

Research on Space Technologies

JAXA promotes space engineering research to stably perform space exploration activities “further”, “with more flexibility” and “in wider directions.”
