The Ballistic missile defence Radar System AN/TPS-59 (V) 3B use now by the Bahrain Defence Force for air surveillance

In May 2004, the U.S. Marine Corps awarded Lockheed Martin a $43.6 million contract to provide the AN/TPS-59(V)3B Ballistic missile defence Radar System, along with associated supplies, equipment and services, to the Kingdom of Bahrain as a foreign military sale. The production line was restarted, and new radar was produced. Earlier in 2007, members of the Bahrain Defence Force were trained how to operate and maintain the system at Lockheed Martin's Radar Systems facility in Syracuse, NY. The Kingdom's TPS-59 radar proceeded smoothly through a site acceptance test in August 2007, and is now being used by the Bahrain Defence Force for air surveillance.

Cassini RADAR view of Titan's north pole

This mosaic is composed of all synthetic-aperture-radar maps of Titan's polar regions acquired by Cassini to date. It has been cropped and reduced in size by 50% from an even larger mosaic available on NASA's Planetary Photojournal. Approximately 60 percent of Titan's northern polar region (poleward of 60 degrees north latitude) has been mapped as of October 2007, and of this area, about 14% appears to be covered with hydrocarbon lakes. The radar images are grayscale; they have been colored here with a color map that applies blue colors to the materials that are darkest to the RADAR instrument, and yellow colors to the materials that are brightest. This color scheme highlights the apparent lakes, but also shows that many lake-like features are not as dark as other lakes, and that darker channels appear to run down the interiors of less dark lakes.

The image is a polar projection, with zero longitude (the sub-Saturnian hemisphere) toward the bottom. The leading hemisphere (centered at 90 degrees W) is to the left, and the trailing hemisphere (centered at 270 degrees W) is to the right. The largest lakes are clustered in an area on Titan's trailing hemisphere.
