KENNEDY SPACE CENTER, FLA. -In the Payload Hazardous Servicing Facility, workers from Lockheed Martin help guide the Mars Reconnaissance Orbiter (MRO) onto a Mars Orbit Insertion Thruster assembly stand for testing. In late July, the MRO will be transported to the Vertical Installation Facility. It will join the Atlas V for the final phase of launch preparations. The spacecraft is then scheduled to undergo a functional test, and a final week of integrated testing and closeouts. The MRO was built by Lockheed Martin for the Jet Propulsion Laboratory in California. It is the next major step in Mars exploration and scheduled for launch from Cape Canaveral Air Force Station in a window opening Aug. 10. The MRO is an important next step in fulfilling NASAs vision of space exploration and ultimately sending human explorers to Mars and beyond.
