The very best time to start the process in the mission is based on the blend of many factors. The main feature is that the flight target goals and also to find the needs of the spacecraft.The vehicle and the space craft will start successfully at all the times. "The interesting thing about our job is each mission is almost completely different from any other mission," said by Eric Haddox.. "We help everybody understand the requirements of the spacecraft and what the capabilities are of the launch vehicle, and try to mesh the two," Haddox . "You've got this object that's going to go flying out into the air and you've got to shoot it," said Haddox. "You have to be able to judge how far away your target is and how fast it's moving, and make sure you reach the same point at the same time."  He also said that "The navigation system on the rocket is going to do what it needs to do to get the spacecraft where it needs to be, but it's not going to be the same trajectory you looked at before,"
