Space Exploration/Space Junk


The solar system is and amazing thing and it is there for us to explore. However, when we explore it, we are leaving behind space junk. What do you think we need to do to reduce space junk but also continue exploring the solar system.

Hi, thanks for writing!  Space debris is a real hazard.  Flights need to be designed so that they do not leave debris in earth orbit (other areas outside earth orbit are so huge that it is not likely a problem) by slowly ejecting spacecraft out of orbit when they cease to function, or reenter earth's atmosphere at an angle that the debris burns up so completely that it is not a hazard or lands in the ocean.  This may involve carrying some additional fuel for the discard path.  Write anytime!
