The final farewell of the Delta 4 Heavy will be delayed. United Launch Alliance scrubbed the launch of the rocket Thursday afternoon, initially halting the countdown because of high winds. After stopping the countdown, ULA called off the launch for the day because a problem with a pump in gaseous nitrogen pipeline. The company had hoped to reschedule the launch for today but said late Thursday that it needed more time to fix the problem and has not announced a new launch date. The launch will be the last not just for the Delta 4 Heavy but also for the entire family of Delta rockets.
