Abstract: On February 3, 2015, the US satellite DMSP-F13 exploded, creating over a hundred of cataloged objects in the 600 km to 1200 km altitude zone. Nearly 50% of these cataloged debris will stay in orbit for over twenty years, suggesting a long term damage to the furture space debris environment. According to the analysis of the influence on the space debris environment from the medium/small breakup debris created by the DMSP-F13 explosion event based on Space Debris Environment Engineering Model (SDEEM), the breakup event caused the increase of the spatial density in the nearby orbital zone, leading to an influence on the spaceships in this area.
