WASHINGTON — The rapidly growing number of satellites orbiting the Earth is causing apprehension, the commander of U.S. Space Command said April 20.
Gen. James Dickinson told lawmakers on Capitol Hill that congestion in space mostly fueled by commercial activity could create safety problems if it’s not managed.

U.S. Space Command’s traffic watchers at Vandenberg Air Force Base, California, currently track about 32,000 objects on orbit, including more than 3,400 active satellites. They estimate the probability of collisions and send warnings to satellite operators.
Dickinson noted that the three largest constellations of satellites today are operated by commercial companies: SpaceX, Planet and Spire.
