CAPE CANAVERAL, Fla. – On Launch Pad 39B at NASA's Kennedy Space Center in Florida, catenary wires are being suspended from the lighting masts on the lightning towers. The catenary wire system under development for the Constellation Program’s next-generation vehicles will significantly increase the shielding level, providing better protection, and further separate the electrical current from vital launch hardware. The system will help avoid delays to the launch schedule by collecting more information on the strike for analysis by launch managers. Photo credit: NASA/Jack Pfaller

STS-44 Mission Specialist (MS) James S. Voss works under the middeck subfloor of Atlantis, Orbiter Vehicle (OV) 104, to repair humidity separator leakage problems. Voss is surrounded by several water tanks and a maze of shuttle wiring and plumbing. Voss earned the nickname of "Bilge Man" because of his time spent on the lower deck tending to the leakage problem. This is the first photo released of a crewmember in this area of the shuttle.

F-8 Digital Fly-By-Wire aircraft in flight. The computer-controlled flight systems pioneered by the F-8 DFBW created a revolution in aircraft design. The F-117A, X-29, X-31, and many other aircraft have relied on computers to make them flyable. Built with inherent instabilities to make them more maneuverable, they would be impossible for human pilots to fly if the computers failed or received incorrect data.

This is a closeup view of the inner workings of the X-59 aircraft. Visible are one the plane’s three lithium-ion batteries (blue box), electrical power system and other wiring components including the vehicle management systems computers (two black boxes) and the white wirings which assist in providing the power that is needed for the aircraft to function in flight. All of these components are essential to maintaining and monitoring the X-59 once it takes to the skies. The X-59 is the centerpiece of the Quesst mission which plans to help enable commercial supersonic air travel over land.

KENNEDY SPACE CENTER, FLA. -- KSC workers stand inside the payload bay of the orbiter Columbia following completion of electrical wiring inspections. At right, behind and below them is the cable tray with the wiring. During launch of Columbia on mission STS-93, a damaged wire caused a short circuit in two separate main engine controllers. As a result of the findings, Shuttle program managers decided to conduct inspections of the wiring in Endeavour's payload bay before its next mission, STS-99. The inspection and possible repair work will lead to a delayed launch date no earlier than Oct.7. The primary payload of the mission is the Shuttle Radar Topography Mission, a specially modified radar system that will gather data for the most accurate and complete topographic map of the Earth's surface that has ever been assembled

The folding seats that make up the Emergency Egress System are seen attached to slide wires at Space Launch Complex 41 where United Launch Alliance and Boeing continue modifications to the pad in order to host missions by the Boeing CST-100 Starliner carrying astronauts and crew. The system recently completed its final test. In the unlikely event of an emergency prior to liftoff, each person on the Crew Access Tower would get into their own seat attached to the wire and slide more than 1,340 feet to a safe area. The wires are situated 172 feet above the pad deck on level 12 of the tower. The Starliner will launch on a ULA Atlas V on mission to low-Earth orbit including those flying astronauts to the International Space Station during missions by NASA's Commercial Crew Program.

KENNEDY SPACE CENTER, FLA. -- An orbiter has more than 300 miles of wires such as these shown here in the cable tray inside Columbia's payload bay. During launch of Columbia on mission STS-93, a damaged wire caused a short circuit in two separate main engine controllers. As a result of the findings, Shuttle program managers have decided to conduct inspections of the wiring in Endeavour's payload bay before its next mission, STS-99. The inspection and possible repair work will lead to a delayed launch date no earlier than Oct.7. The primary payload of the mission is the Shuttle Radar Topography Mission, a specially modified radar system that will gather data for the most accurate and complete topographic map of the Earth's surface that has ever been assembled

KENNEDY SPACE CENTER, FLA. -- On Launch Pad 39A at NASA's Kennedy Space Center, foam is being replaced around the engine cutoff, or ECO, sensor system connector and wiring on space shuttle Atlantis' external tank. The foam was removed to enable engineers to remove and replace a feed-through ECO sensor connector on the tank. The feed-through connector passes the wires from the inside of the tank to the outside. Results of a tanking test on Dec. 18 pointed to an open circuit in the feed-through connector wiring, which is located at the base of the tank. The pins in the replacement connector were precisely soldered to create a connection that allows sensors inside the tank to send signals to the computers onboard Atlantis.

KENNEDY SPACE CENTER, FLA. - Jeff Huet, with United Space Alliance, is conducting electromagnetic interference and ground resistance testing on wiring in the aft engine compartment on Space Shuttle Discovery using various test equipment, such as current probes, amp meters, digital volt meters, breakout boxes, Nicollet recorders, oscilloscopes and time domain reflectometers. Other testing will evaluate wiring runs and connections for any reactions under semi-cryogenic conditions. Other testing will evaluate wiring runs and connections for any reactions under semi-cryogenic conditions, using a Nicolet data recorder. Engineering teams have been working through a troubleshooting plan to address an issue with a liquid hydrogen low-level fuel sensor circuit. The sensor circuit failed a routine prelaunch check during the countdown July 13, delaying Discovery’s first launch attempt on Return to Flight mission STS-114.
