(JAXA) – The Japan Aerospace Exploration Agency (JAXA) carried out the following deployment operations on the onboard mission equipment of the “KAGUYA” (SELENE) between October 28 and 31, 2007 (Japan Standard Time, JST.)

The KAGUYA is a lunar explorer launched from the Tanegashima Space Center. The satellite is in good health.

- Lunar magnetometer (LMAG)
Equipment for observing the lunar magnetic field. A mast in which the magnetometer is attached at the top was extended to about 12 meters to be ready for observation.

-Lunar Radar Sounder (LRS)
Equipment to measure lunar tectonic features up to about 5 km in depth by observing radio frequency reflection from the lunar surface and subsurface using radar radio wave.

The LRS also observes radio frequencies from other planets when the satellite is on the back side of the moon where no artificial radio waves from the Earth interfere with the observations. Two units of two dipole antennas (four antennas in total,) which had been stowed into the satellite, were extended to about 15 meters to be ready for observation.

- Upper Atmosphere and Plasma Imager (UPI)
Equipment to observe atmospheric lights and auroras from the lunar orbit by two kinds of telescopes. The telescopes are attached to a structure called the “gimbal,” which had been fixed on the satellite wall. The gimbal was deployed for observation.
