Jeffrey A. Hoffman (left) and Story Musgrave are partially silhouetted against the Indian Ocean as they work to install two new Magnetic Sensing System (MSS) magnetometers on the Hubble Space Telescope (HST). Musgrave is anchored to the end of the Space Shuttle Endeavour's Remote Manipulator System (RMS) arm. The HST is positioned along the southern end of Madagascar, which is 325 nautical miles below. Visible on the western coast are the sediment laden Onilahy and Fiherenana Rivers which empty into Saint Augustin Bay. North of Fiherenana River is the Mangoky River. The circular feature on the southern end of Madagascar and to the right of HST is the L'ivakoany Mountains. The eastern coast is relatively straight compared to the western coast.
