CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, workers are constructing 40-foot-diameter dish antenna arrays for the Ka-Band Objects Observation and Monitoring, or Ka-BOOM system. The antennas will be part of the operations command center facility. The construction site is near the former Vertical Processing Facility, which has been demolished. The Ka-BOOM project is one of the final steps in developing the techniques to build a high power, high resolution radar system capable of becoming a Near Earth Object Early Warning System. While also capable of space communication and radio science experiments, developing radar applications is the primary focus of the arrays. Photo credit: NASA/ Ben Smegelsky
