What does space science bring us?
It does not merely unravel the mysteries of the universe.
The desire to understand the vast universe surrounding the earth is in fact the quest to understand the earth we live on.


ISAS has been developing and operating various spacecraft for more advanced space activities and/or understanding the origin and evolution of the solar system and its biosphere.

Launch Vehicles

To deliver a spacecraft securely to the planned orbit in space, ISAS has been developing various launching rockets.

Sounding Rockets

Sounding rockets are utilized for various purposes such as observing the upper atomosphere on site or demonstrating cutting-edge technologies.

Scientific Balloons

More frequent flight opportunities than rockets and recovery utilization of mouted instruments enable ambitious experiments and observations.
