A new U.S. Air Force satellite,SBSS will provide the first full-time, space-based surveillance of hundreds of satellites and thousands of pieces of debris that could crash into American and allied assets circling the Earth.
If all goes as planned, the Space-Based Space Surveillance satellite, scheduled for a July 8 launch from Vandenberg Air Force Base, Calif., will have an unobstructed, around-the-clock view of the increasingly heavy traffic in Earth orbit — something the Air Force doesn't have now.
Currently, the Air Force relies on a ground-based network of radar and optical telescopes around the globe to monitor about 1,000 active satellites and 20,000 pieces of debris. The telescopes can be used only on clear nights, and not all radar stations are powerful enough to detect satellites in deep space orbit, about 22,000 miles from Earth.
