The operation status of satellites/probes is basically categorized into the following phases: “Under development”, “In Operation”, “Latter Phase In Operation” ,“Post operation” and “Transferred”.
- In Operation: Operation during regular mission period (including initial operation period after launch)
- Latter Phase In Operation: Operation following the completion of the regular mission period operation. When completing the regular mission period operation, the condition of the satellite/probe is checked to decide whether a latter phase in operation is required.
Major Research and Development
This is a ground station built in Saku City,Nagano Prefecture for the purpose of enabling telecommunications with deep space explorationprobes.
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 origen 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
In Operation
XRISM is a new X-ray astronomical satellite which observes plasma in stars and galaxies. With a new generation of X-ray imaging spectroscopy technologies, XRISM will resolve mysteries regarding the formation of the universe.
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
This satellite is designed to elucidate how the Sun's high-temperature plasma is created and how it affects the Earth and planets by precise spectroscopic observation of ultraviolet radiations emitted from the Sun through the onboard telescope with unprecedented high sensitivity. Japan is leading the development of the mission in cooperation with the United States and European countries.
Operation Completed
An aurora observation satellite that observed the physical phenomena taking place in geospace while collecting detailed data in collaboration with the ground stations
Suzaku to probe into black holes and galaxy clusters to study their structure and evolution.
AKARI: Seeking an understanding of the formation and evolution of galaxies
Lunar and Planetary Exploration Spacecraft
In Operation
Small probe challenges an accurate lunar landing (Concluded operations on the lunar surface: August 23, 2024)
Along with NASA’s DART (Double-Asteroid Redirection Test) mission, the technology required for planetary defense will be demonstrated for the first time in history, in addition to investigating planetary formation and evolution processes.
Latter Phase In Operation
Hayabusa2 to clarify the origen and evolution of the solar system as well as life matter
AKASTUKI will elucidate the mysteries of Venus, Earth’s twin sister.
Japan will initiate the beginning of a new era of Venusian exploration.
Under Development
DESTINY⁺ is a deep space mission that unites engineering and science objectives.
