In order to avoid collision with SpaceX’s Starlink44 satellite, the European space agency (ESA) said on September 2, 2019 that it fired the thrusters of the Aeolus satellite to avoid collision. In this paper, the collision probability of two space objects is analyzed. In addition, considering the crowded space environment in the future, the number of collisions in a certain period of time was simulated. Meanwhile, compared with the number of possible collisions within 365 days of the existing space target and the number of possible collisions after the addition of Starlink satellite group. The result shows that the future space environment will be much more crowded than expected. On this basis, some reasonable suggestions are put forward for the future space development to ensure the safety and reliability of the future space.
