Spacecraft

The Ziyuan 3 satellite was constructed by the China's China Academy of Space Technology (CAST), and carries three cameras produced by the Changchun Institute of Optics, Fine Machinery and Physics. A camera aligned normal to the Earth's surface will produce images with a spatial resolution of 2.5 metres (8 ft 2 in), whilst the other two, offset at 22° forward and aft, have spatial resolutions of 4.0 metres (13.1 ft).[3] In addition to the three cameras, Ziyuan-3 carries an infrared multispectral spectrometer, with a spectral resolution of 6.0 metres (19.7 ft).[1][3] The satellite is used to provide imagery to monitor resources, land use and ecology, and for use in urban planning and disaster management.[4] It had a mass at launch of 2,630 kilograms (5,800 lb). The satellite has a planned operational lifetime of 4 years with a possible extension to 5 years.[5]

Launch

Ziyuan 3 was launched by a Long March 4B carrier rocket, flying from Launch Complex 9 at the Taiyuan Satellite Launch Center. The launch occurred at 03:17:00 UTC on 9 January 2012, and was the first orbital launch of the year.[1] VesselSat-2 was launched as a secondary payload on the same rocket.[6]
