    Landsat, a remote sensing Earth Resources Technology satellite, has been acquiring repetitive coverage of the Earth since 1972 when Landsat 1 was launched. Since then, four others have been in operation. Landsat 1, 2, and 3 flew in a circular orbit 913 kilometers (570 miles) above the Earth's surface and circled the Earth every 103 minutes, or about 14 times a day. Landsat 4 and 5 fly about 705 kilometers (440 miles) above the Earth and circle every 98 minutes.

    Landsat 4 and 5 are still operating. Landsat 6 was launched in 1993 but did not achieve orbit and was lost. Landsat 7 is in planning stages. For more information on Landsat 7 status, see the Landsat Program Home Page.

Commentary:

    Data center only collected the data covering the West China, especially the Himalayas regions. The main objective is monitoring the glacier and snow cover in the cryoshpere of China.
