Abstract (in Japanese) (See Japanese page) 
(in English) The lunar explorer Kaguya (Selene) of the Japan Aerospace Exploration Agency (JAXA) was launched on September 14, 2007. This lunar explorer is equipped with 15 observation instruments and will orbit the moon for about 1 year to perform scientific research on subjects such as the moon's origin. As part of this mission, NHK developed a high definition camera system (HDTV) to take high definition still and moving images of the earth rising from the moon. This system enables the compression of images shot using a small 2.2 million-pixel high definition camera, and can record moving images of a maximum of 1 minute on a 1GB memory. To enhance reliability, each instrument was duplicated and underwent various tests to ensure that they can operate under severe space conditions. For example, vibration tests under the vibration conditions incurred during a rocket launch, which is 17G, were performed. The test results were then used to make various adjustments such as strengthening the camera boards or CCDs. The preparation process took about 7 years to complete and the large-scale project of taking images of a “beautiful earthrise from the surface of the moon” was finally achieved.
