China publishes its first full map of the moon surface in Beijing, capital of China, Nov. 12, 2008, about a year after its first lunar probe -- Chang'e-1 -- was launched. (Xinhua/Li Xiaoguo)

On 31 October 2008, the Japanese Moon explorer SELENE (KAGUYA) completed its nominal observation period of about one year from December 2007 and entered the extended mission period that is expected to be about a half year using surplus fuel. During the SELENE nominal mission period, the push-broom Terrain Camera (TC) [1] aboard KAGUYA, successfully acquired 10 m resolution stereoscopic data at solar elevation angles of around 30° and monoscopic data at angles of less than 30° for almost the entire surface of the Moon.
The rate of discrete cosine transform (DCT) compression of TC data was 10 to 20% (100% without compression). There was very little or no block noise due to compression. Most image data was acquired by TC in sequential revolutions of SELENE (interval of about 2 hours) and thus was easily superposed with sequential overlapped image data to yield large
mosaicked data. Unobserved areas that totaled less than 5% of the whole surface of the Moon and are planned to be observed in the extended-mission period.
The TC is currently working very well after the end of the nominal-mission period. No defective pixels have been found so far.

Today, Chandrayaan-1 spacecraft has successfully reached its intended operational orbit at a height of about 100 km from the lunar surface.
From this operational circular orbit of about 100 km height passing over the polar regions of the moon, it is intended to conduct chemical, mineralogical and photo geological mapping of the moon with Chandrayaan-1’s 11 scientific instruments (payloads). Two of those 11 payloads – Terrain Mapping Camera (TMC) and Radiation Dose Monitor (RADOM) – have already been successfully switched ON. TMC has successfully taken the pictures of Earth and moon.

interesting details about LRO:
- 62 TB of raw data are expected from this LROC camera system during the nominal one-year mission
- 5 year extension possible (!)
