Kaguya (SELENE)(glossary entry)
Credit: Kaguya (Selene)
Japanese lunar exploration satellite, launched on September 14, 2007, and operating in lunar orbit until June 10, 2009. Its complement of instruments included high resolution cameras, spectrometers, altimeters and a pair of high definition television cameras used to collect moving images of the Moon as seen from orbit. It viewed the Moon from a distance of about 100 km.
- Officially known as the SELENE mission, following Japanese tradition, the orbiter was renamed after its successful launch, to Kaguya. There are also two sub-satellites in lunar orbit, now known as Okina and Ouna, that are used for probing the Moon's gravity field.
- The main website includes a 2-page PDF brochure briefly describing the mission objectives and instruments.
- The still Image Gallery can be viewed only via an Adobe Flash interface. Click on the boxes near the top of the screen to select pages related to results from the different instruments (e.g. "TC" = terrain camera), then use the "Previous" and "Next" buttons that will appear near the bottom of the page to step through the pages. The Japanese and English versions of the gallery are not identical. Entries tend to appear first in the Japanese version, and then later in the English one.
- Video presentations are in a separate gallery.
- The Japan Broadcasting Corporation (NHK), which is a sponsor of Kaguya's High Definition Television (HDTV) experiment, has a separate Gallery of still and video images, focused especially on pictures showing the Earth. Clicking on the blue dots on the Nearside/Farside maps displays the images shown separately in the "Lunar Landscapes" at the bottom of the page.
- Low resolution Digital Elevation Models (DEM's) of the Lunar North Pole, Lunar South Pole and Entire Lunar Surface taken using the Laser Altimeter are available at the Kaguya Website.
- The main source of raw Kaguya science data (other than HDTV?) is the SELENE Data Archive which has a sometimes frustrating to use web interface requiring free registration.

- A number of Kaguya images have been released on the web, but not in a form that is indexed or readily searchable. Here is an informal attempt to correct that oversight:
