China sent a satellite into orbit as part of the UN 2030 Agenda for Sustainable Development. A Long March 6 rocket, one of China's new-generation launch vehicles, lifted off from Taiyuan Satellite Launch Center in north China. The mission’s satellite SDGSAT-1, is designed to orbit at an altitude of around 314 miles (505 kilometers) and use thermal infrared, low light level and multispectral cameras to collect data to help evaluate the Sustainable Development Goals indicators. The data will be used to assess the impacts and changes through the interaction between human urban, residential and coastal activities and nature.
