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-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.

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.

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.

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.
