NASA's F-15B Research Testbed aircraft recently flew in the supersonic shock wave of a U.S. Navy F-5E in support of the F-5 Shaped Sonic Boom Demonstration (SSBD) project, part of the Defense Advanced Research Projects Agency's (DARPA) Quiet Supersonic Platform (QSP) program. The flights originated from the NASA Dryden Flight Research Center at Edwards, California. Four flights were flown in order to measure the F-5E's near-field (close-up) sonic boom signature at Mach 1.4, during which more than 50 shockwave patterns were measured at distances as close as 100 feet below the F-5E.

JSC2004-E-16343 (March 2004) --- Robonaut – which uses a head, torso, arms and dexterous hands to perform tasks using the same tools used by human spacewalkers – was fitted with a movable leg that ended in a “foot” that was a common interface for the standard Work Interface Facility (WIF) anchors on the International Space Station (ISS). The Robonaut Project is a collaborative effort with the Defense Advanced Research Projects Agency (DARPA), and has been under development at Johnson Space Center (JSC) for several years.

JSC2004-E-16339 (March 2004) --- Robonaut - which uses a head, torso, arms and dexterous hands to perform tasks using the same tools used by human spacewalkers – has both hands free once its leg is anchored in a standard Work Interface Facility (WIF) attached to the test panel. The Robonaut Project is a collaborative effort with the Defense Advanced Research Projects Agency (DARPA), and has been under development at Johnson Space Center (JSC) for several years.

JSC2004-E-16342 (March 2004) --- Tests of Robonaut’s ability were conducted on the Precision Air-Bearing Floor in Johnson Space Center’s (JSC) Space Vehicle Mockup Facility. Robonaut was mounted to a pressurized air sled, which allowed teleoperators to emulate some of the conditions of weightlessness. The Robonaut Project is a collaborative effort with the Defense Advanced Research Projects Agency (DARPA), and has been under development at JSC for several years.

JSC2004-E-16341 (March 2004) --- Robonaut uses a standard human spacewalk tether to connect itself to an International Space Station (ISS) exterior handrail on the test panel. The Robonaut Project is a collaborative effort with the Defense Advanced Research Projects Agency (DARPA), and has been under development at Johnson Space Center (JSC) for several years.

STS113-370-012 (2 December 2002) --- The horizon of a blue and white Earth and the blackness of space form the backdrop for this view, as two miniature satellites are released from the Space Shuttle Endeavour as part of an experiment referred to as MEPSI. Funded by the Defense Advance Research Projects Agency (DARPA), the two small satellites, which are tethered together, were released from Endeavour’s payload bay (visible in foreground) to fly free for three days as a technology demonstration of the launcher and use of micro- and nano-technologies in space systems.

The right wing of the X-31 Enhanced Fighter Maneuverability Technology Demonstrator Aircraft is seen here being put into a shipping container May 18, 1995, at NASA's Dryden Flight Research Center, Edwards, California, by U.S. and German members of the program. To fit inside an Air Force Reserve C-5 transport, which was used to ferry the X-31 to Europe on May 22, 1995, the right wing had to be removed. Manching, Germany, was used as a staging base to prepare the aircraft for participation in the Paris Air Show. At the air show on June 11 through the 18th, the X-31 demonstrated the value of using thrust vectoring (directing engine exhaust flow) coupled with advanced flight control systems to provide controlled flight at very high angles of attack. The aircraft arrived back at Edwards in an Air Force Reserve C-5 on June 25, 1995, and off loaded at Dryden the 27th. The X-31 aircraft was developed jointly by Rockwell International's North American Aircraft Division (now part of Boeing) and Daimler-Benz Aerospace (formerly Messerschmitt-Bolkow-Blohm), under sponsorship by the U.S. Department of Defense and the German Federal Ministry of Defense.

Because the number two X-29 at NASA's Ames-Dryden Flight Research Facility (later the Dryden Flight Research Center) flew at higher angles of attack than the number one aircraft, it required a spin chute system for safety. The system deployed a parachute for recovery of the aircraft if it inadvertently entered an uncontrolled spin. Most of the components of the spin chute system were located on a truss at the aft end of the aircraft. In addition, there were several cockpit modifications to facilitate use of the chute. The parachute was made of nylon and was of the conical ribbon type.

This photo shows the X-29 during a 1991 research flight. Smoke generators in the nose of the aircraft were used to help researchers see the behavior of the air flowing over the aircraft. The smoke here is demonstrating forebody vortex flow. This mission was flown September 10, 1991, by NASA research pilot Rogers Smith.

NASA image acquired December 3, 2012 As predicted, Typhoon Bopha made landfall on the Philippine island of Mindanao overnight December 3–4, 2012. Known in the Philippines as Pablo, the storm was blamed for 43 deaths and 25 injuries as of December 4, according to the Philippine Daily Inquirer. (To view the high res or to read more go to: <a href="http://1.usa.gov/XnYhVG" rel="nofollow">1.usa.gov/XnYhVG</a>) The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this image around 1:12 a.m. local time on December 4 (17:12 UTC on December 3). This image is from the VIIRS “day-night band,” which detects light in a range of wavelengths from green to near-infrared and uses filtering techniques to observe signals such as gas flares, auroras, wildfires, city lights, and reflected moonlight. Bopha remained a powerful typhoon as it made landfall on Mindanao, retaining a distinct eye and spiral shape as storm clouds stretched over the eastern part of the island. Unisys Weather reported that Bopha carried super-typhoon strength at the time it was coming ashore. William Straka, associate researcher at the Cooperative Institute for Meteorological Satellite Studies at the University of Wisconsin–Madison, estimated that the storm spanned at least 1,677 kilometers (1,042 miles). Bopha lost some strength after making landfall. On December 4 (late in the evening in the Philippines), the U.S. Navy’s Joint Typhoon Warning Center (JTWC) reported that the storm had maximum sustained winds of 95 knots (175 kilometers per hour) and gusts up to 115 knots (215 kilometers per hour)—still a fierce storm, but weakened since the previous day. The JTWC projected storm track showed Bopha continuing its movement toward the west-northwest, passing over the southern Philippines toward the South China Sea.
