Combat Balloon Lifts Off: A host of combat experiments are under way this week during the 2006 Joint Expeditionary Force Experiment, including one that will employ balloons staged in “near space” to aid line-of-sight communications on the ground. Dubbed “Combat Skysat,” the program places a radio repeater-linked to a weather-type balloon in near space—the layer of the atmosphere between aircraft airspace and satellites. The repeater can “bounce” ground transmission, extending the range and making them clearer. The balloon takes about 20 minutes to launch and can stay in the air an average of 12 hours per flight.
RTX, parent of Raytheon, Collins and Pratt & Whitney, is getting out of the space prime business and focusing on its "strengths" as a maker of space sensors, buses, and components, company COO Chris Calio said during an earnings call.
