VANDENBERG AIR FORCE BASE, Calif. -- Andrew Carson, NPP program executive, NASA Headquarters, Washington, DC, participates in the prelaunch news conference at Vandenberg Air Force Base, Calif., for NASA’s National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) spacecraft. NPP represents a critical first step in building the next-generation of Earth-observing satellites. NPP will carry the first of the new sensors developed for this satellite fleet, now known as the Joint Polar Satellite System (JPSS), to be launched in 2016. NPP is the bridge between NASA's Earth Observing System (EOS) satellites and the forthcoming series of JPSS satellites. The mission will test key technologies and instruments for the JPSS missions. NPP is targeted to launch Oct. 28 from Space Launch Complex-2 aboard a United Launch Alliance Delta II rocket. For more information, visit http://www.nasa.gov/NPP. Photo credit: NASA/VAFB

CAPE CANAVERAL, Fla. – A NASA C-9 “Pathfinder” DC-9 takes off from the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida ahead of space shuttle Discovery, which is bolted to the top of a Shuttle Carrier Aircraft. The craft are set to begin their 3 1/2 hour ferry flight to the Washington Dulles International Airport in Virginia at about 7 a.m. EDT. The Pathfinder will fly about 100 miles ahead of the attached pair, making sure the flight path is free of harmful weather or hazardous conditions. Discovery is leaving Kennedy after more than 28 years of service beginning with its arrival on the space coast Nov. 9, 1983. Discovery first launched to space Aug. 30, 1984, on the STS-41D mission. Discovery is the agency's most-flown shuttle with 39 missions, more than 148 million miles and a total of one year in space. Discovery is set to move to the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center on April 19 where it will be placed on public display. For more information on the SCA, visit http://www.nasa.gov/centers/dryden/news/FactSheets/FS-013-DFRC.html.

A Grumman OV-1B Mohawk maps Great Lakes’ ice flows for the National Aeronautics and Space Administration (NASA) Lewis Research Center in Cleveland, Ohio. The regular freezing of large portions of the Great Lakes during the winter frequently stalled the region’s shipping industry. Lewis developed two complementary systems to monitor the ice. The Side Looking Airborne Radar (SLAR) system used microwaves to measure the ice distribution, and electromagnetic systems employed noise modulation to determine the thickness of the ice. Once this dual system was in place, the information could be generated during a single pass of a research aircraft and quickly distributed to ship captains planning their routes. The SLAR was superior to aerial photography for this task because it was able to penetrate cloud cover. The SLAR system used pulsed microwaves to examine a band of ice or water on either side of the aircraft up to 31 miles wide. The Lewis ice mapping devices were first tested during the winter of 1972 and 1973. The system was installed on the tail of the Coast Guard’s OV-1B aircraft. An infrared thermal mapping instrument was installed on Lewis’ DC-3 to determine the ice temperature and estimate its thickness. The team created 160 ice charts that were sent to 28 ships and 2 icebreakers. Shipping was able to continue throughout the season for the first time that winter.
