Vietnam’s first remote sensing satellite, VNRED Sat-1, was launched by Arianespace from the Guiana Space Center, French Guiana, May 7, 2013. The satellite’s measuring swath is 17.5 km (~11 mi) with a resolution of 2.5 m (8.2 ft) for panchromatic data and 10-m (~33-ft) reso­lution for its four multispectral bands, and has a revisit time of three days. Data from VNREDSAT-1 are being used for urban management and natural resource moni­toring, including hazards and disasters in Vietnam. Vietnam plans to launch the second remote sensing satellite, VNREDSat-1B, into orbit by 2017
