Sohae Satellite Launching Station
Sohae Satellite Launching Station (, also known as Tongch'ang-dong Space Launch Center and Pongdong-ri) is a rocket launching site in Tongch'ang-ri, Cholsan County, North Pyongan Province, North Korea. The base is located among hills close to the northern border with China. The spaceport was built on the site of the village Pongdong-ri which was displaced during construction. It was the site for the 13 April 2012 launch of the North Korean satellite Kwangmyŏngsŏng-3, which was launched to celebrate the 100th anniversary of the birth of Kim Il-Sung. The rocket launch failed, but on 12 December of the same year Kwangmyŏngsŏng-3 Unit 2 was successfully launched and brought into Earth orbit.

Earth Observation
Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. It can be performed via remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example). According to the Group on Earth Observations (GEO), the concept encompasses both " space-based or remotely-sensed data, as well as ground-based or in situ data". Earth observation is used to monitor and assess the status of and changes in natural and built environments.
