MISSIONS

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

Spacecraft

ISAS has been developing and operating a fleet of spacecraft for advancing activities in space, to understand the Universe, and explore the origin and evolution of the Solar System and its biosphere.

Launch Vehicles

To deliver a spacecraft securely to a planned orbit in space, ISAS has been developing different classes of launching rockets.

Sounding Rockets

Sounding rockets are utilized for a variety of purposes such as observing the upper atmosphere on site and demonstrating cutting-edge technologies.

Scientific Balloons

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