NEW IMAGE OF SATURNS RINGS
Although it may look to our eyes like other images of the rings, this infrared image of Saturn's rings was taken with a special filter that will only admit light polarized in one direction. Scientists can use these images to learn more about the nature of the particles that make up Saturn's rings. The bright spot in the rings is the "opposition surge" where the Sun-Ring-Spacecraft angle passes through zero degrees. Ring scientists can also use the size and magnitude of this bright spot to learn more about the surface properties of the ring particles. This view looks toward the sunlit side of the rings from about 19 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on Aug. 18, 2013 using a spectral filter sensitive to wavelengths of near-infrared light centered at 705 nanometers. The view was acquired at a distance of approximately 712,000 miles (1.1 million kilometers) from Saturn and at a Sun-rings-spacecraft, or phase, angle of 7 degrees. Image scale is 43 miles (68 kilometers) per pixel. Image Credit-NASA-JPL-Caltech-Space Science Institute.

ANTARES ROCKET LAUNCH
FROM: NASA
Orbital Sciences Corp. launched its Cygnus cargo spacecraft aboard its Antares rocket at 1:07 p.m. EST Thursday, Jan. 9, 2014, from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia, beginning the Orbital-1 cargo resupply mission to the International Space Station. The Cygnus spacecraft is now traveling 17,500 mph in Earth's orbit to rendezvous with the space station on Sunday, Jan. 12. Over the next two and a half days, Cygnus will perform a series of engine firings to put it on track for a rendezvous with the station. When the vehicle reaches the capture point about 30 feet from the complex, Expedition 38 Flight Engineers Mike Hopkins and Koichi Wakata will use Canadarm2, the station’s 57-foot robotic arm, to reach out and grapple Cygnus at 6:02 a.m. The crew then will use the robotic arm to guide Cygnus to its berthing port on the Earth-facing side of the Harmony node for installation beginning around 6:20 a.m. NASA television coverage of the rendezvous and berthing begins at 5 a.m. Sunday, Jan. 12, followed at 7 a.m. with coverage of the installation. For its first official commercial resupply mission, designated Orbital-1, Cygnus is delivering 2,780 pounds of supplies to the space station, including vital science experiments for the Expedition 38 crew members aboard the orbiting laboratory. Orbital Sciences successfully proved the capability of the Cygnus spacecraft during its first and only demonstration flight to the station back in September 2013.
