Protecting satellites and signals from jamming or hacking is taking on outsized importance in nuclear forces modernization.
An Orbital ATK Minotaur 4 rocket lifted off from Cape Canveral, Florida, early Saturday morning, carrying the U.S. Defense Department's Operationally Responsive Space (ORS)-5 satellite. The launch comes as a debate is flaring up again about whether companies should be able to use converted surplus intercontinental ballistic missile (ICBM) motors to launch commercial satellites
The Ground-based Midcourse Defense (GMD) is designed to intercept and destroy missiles during the midcourse of their trajectory through space.
The present-day debate about a policy change to allow the use of ICBM motors to provide lower cost commercial launches mirrors one from the early 1990s.
