Mission: Space surveillance is a critical part of USSPACECOM's mission and involves detecting, tracking, cataloging and identifying man-made objects orbiting Earth, i.e. active/inactive satellites, spent rocket bodies, or fragmentation debris. Space surveillance accomplishes the following: Predict when and where a decaying space object will re-enter the Earth's atmosphere; Prevent a returning space object, which to radar looks like a missile, from triggering a false alarm in missile-attack warning sensors of the U.S. and other countries; Chart the present position of space objects and plot their anticipated orbital paths; Detect new man-made objects in space; Produce a running catalog of man-made space objects; Determine which country owns a re-entering space object; Inform NASA whether or not objects may interfere with the space shuttle and Russian Mir space station orbits.
