It will then go into the reactor control system which controls the attitude control thrusters. After that loading is completed, the maneuvering system will be loaded with monomethyl hydroxide. The loading is expected to last into this weekend. After the loading is completed, early next week flight information will be given to the oribiter's computers in preparation for the 5 October lift off and 9 October launch.
