SAW devices aim for asteroid research
A NDK product story

NDK's high-precision SAW devices were installed in the spacecraft "MUSE-C" launched into space on 9th May in Japan by ISAS.
NDK's high-precision SAW devices were installed in the spacecraft "MUSE-C" (nicknamed Hayabusa, which means falcon) launched into space on 9th May in Japan by ISAS (The Institute of Space and Astronautical Science).
The mission of the spacecraft is to travel to the asteroid "1986SF36", which is located between Mars and Jupiter, land on its surface, collect samples of the surface, and return them to earth.
When Hayabusa arrives at the asteroid it will hover about 10m above the surface.
It will then drop a "target marker" onto the predetermined landing point.
The target marker is about 10cm in diameter and when it collides with the asteroid the impact is equivalent to being fired from a cannon.
NDK's high precision SAW devices were used in both the spacecraft and the target marker.
Designed by NRS Technologies (a joint venture company of NDK and NEC Corporation) these SAW devices were selected because of their high reliability and high antishock performance.
The SAW devices were used in the guidance and communication systems.
The MUSES-C (Mu Space Engineering Spacecraft-3) was successfully launched from Kagoshima Space Centre by an M-V-5 launch vehicle.
It was a beautiful launch, and became a signal fire that symbolises a restoration of Japan's space science.
