rocket blasted off at 7:44 a.m. from the Jiuquan Satellite Launch
Center in northwest China and soon sent L-SAR 01A satellite into preset
orbit. Synthetic aperture radar (SAR) is a type of microwave
remote sensing technology that's used to study geological environment
and monitor landslides and earthquakes. It is the country's
largest land observation satellite operating in orbit by caliber, a key
measurement to gauge capability. The satellite weighs 3.2 tonnes, with
an antenna spanning over 33 square meters. The satellite enables
China to conduct mass terrain survey at millimeter precision. It also
helps scientists to better survey areas covered by forest. The operation of the satellite can significantly reduce China's
dependence on SAR data provided by other countries, according to a
statement from Shanghai Academy of Spaceflight Technology. The
Long March-4C rocket, developed by the Shanghai Academy of Spaceflight
Technology, can carry diverse types of satellites to orbits at different
height. It's the first launch of the Long March 4 rocket series in this
year. The mission also marked the 407th flight of the Long March carrier rockets, said the launch center.
