A military weather satellite remained on the ground Sunday after the second launch attempt in as many days was scrubbed because of technical problems. The countdown to the 8:58 am EST (1358 GMT) launch of a Titan 2 was stopped at T-19 seconds when an oxidizer "prevalve" in the rocket opened too slowly. Launch controllers scrambled to correct the problem and restarted the countdown from T-90 seconds, but the launch was aborted again when it became clear liftoff would not take place before the end of the ten-minute launch window, according to Spaceflight Now. The launch has been rescheduled for Tuesday; if the Titan does not launch then it will face a two-month delay to refurbish the rocket. The booster, a refurbished ICBM, is carrying the Defense Meteorological Satellite Program (DMSP) F19 spacecraft, which will provide weather data for the U.S. military from its perch in a circular, polar low-Earth orbit.
