标题：Space Station Deorbit: An Important Safety Procedure

Space stations are a crucial part of our space program, but they must eventually deorbit to prevent them from becoming space debris and posing a safety hazard to other spacecraft. Deorbiting is a complex process that requires precise planning and execution to ensure the safety of the astronauts and the station itself.

The process begins with monitoring the station"s orbit and calculating the precise moment when it will safely re-enter the atmosphere. This information is then used to prepare for the deorbit burn, which involves firing the station"s thrusters to slow its velocity and guide it towards a safe re-entry point. During this phase, the station is closely monitored to ensure that everything is going according to plan.

Once the deorbit burn is complete, the station begins its descent into the atmosphere, where it will burn up and disintegrate, leaving no trace behind. This process ensures that the station does not pose a risk to future space missions or endanger human life in space. It also helps to minimize space debris, which can pose a serious threat to our space program and other spacecraft.
