GO for launch ! 2120 GMT (4:20 p.m. EST) T-minus 4 minutes and counting. The countdown has restarted for the launch of Delta 276 and Globalstar 7. Weather has been declared GO for launch! 2119 GMT (4:19 p.m. EST) Now one minute away from resuming the countdown. A network of tracking stations around the globe will be used to collect and relay telemetry data from the Delta 2 rocket during launch today. At liftoff, the TEL-4 tracking station here at the Cape will provide coverage of the first stage of flight and second stage engine ignition. As the vehicle heads up the Eastern Seaboard, the Air Force's New Hampshire tracking site will acquire signal about 5 minutes, 24 seconds into flight. New Hampshire will cover the mission for 6 1/2 minutes through the first cutoff of the second stage. Also during the New Hampshire pass, live video could be received from a special video camera mounted on the dispenser that holds and will release the Globalstar satellites. Additional Air Force tracking sites in Oakhanger, England and Diego Garcia in the Indian Ocean will receive data during the long, quiet coast period before the second start of the second stage. Just prior to reignition, the NASA tracking site in Canberra, Australia will pick up the rocket's signal to cover the critical second burn of the second stage and deployment of all four satellites. Under two hours into flight, after the satellites have separated, the Air Force's Colorado station will pick up the signal from the second stage to watch two scheduled engine firings. The first is an evasive maneuver to move the spent stage away from the Globalstar satellites. The second will deplete the stage's remaining onboard fuel supply. 2117 GMT (4:17 p.m. EST) The plan being discussed is to pick up the count at 4:20 p.m. and take the clocks down to T-minus 70 seconds in hopes the weather becomes acceptable. If conditions are OK, liftoff will occur at 4:24 p.m. EST. If weather remains unfavorable, the countdown will stop and today's attempt will be scrubbed. 2115 GMT (4:15 p.m. EST) Five minutes left in this hold if the weather is acceptable. 2112 GMT (4:12 p.m. EST) The Range says it is watching a boat
