| In 2005, Lockheed Space Systems selected the company to develop a laser camera system to be placed aboard the Hubble Robotics Vehicle that will safely deorbit the telescope and guide its re-entry trajectory. |
| It also assumes that there would be enough room in the shuttle's cargo bay for the deorbit module. |
| The astronauts completed a test of the Reaction Control System steering thrusters that will help control Endeavour's attitude and speed after the deorbit burn. |
| First, an orbiting weapon required elaborate spacecraft systems, such as retro-rockets to deorbit it, others to guide it, and still others to arm it. |
| The crew performs reaction control system hot fire and reviews tomorrow's deorbit timeline. |
| Deorbit preparation included stowing away equipment, putting on pressure suits, and closing the Payload Bay doors. |
