The article reports on the efforts of the U.S. Air Force to protect its space operations. It lunched a new study to reassess and protect its space operations. Another effort is using the Counter Communications systems, which employs mobile antennas to jam an enemy's access to space. Another concern of the USAF is the ability of micro-satellites to evade U.S. ground-and-space-based sensors that track objects in orbit.
