The satellite will be used for a variety of applications including scientific experiments, land resources survey, crop yield estimation, disaster prevention and alleviation. The satellite was developed by DFH Satellite Co., Ltd.. The rocket for the mission was developed by the SAST. This was the 17th launch in 2012展开更多
John Njoroge hopes to be an astro naut when he grows up. The seven- year old Kenyan boy said that flying must be an exciting job. His influenee comes from watching movies and playing video games.
