Following the successful installation of mounting brackets, technicians successfully installed the pallet for the eXternal Visibility System, or XVS, onto the X-59 Quiet SuperSonic Technology X-plane, also known as X-59 QueSST. The pallet installation marks an assembly milestone as the first NASA flight systems hardware to be installed onto the vehicle. X-59 will fly to demonstrate the ability to produce quiet thumps at supersonic speeds, instead of the typical, loud sonic booms associated with supersonic flight.

At Launch Pad 39B, two holes caused by hail on Space Shuttle Discovery's external tank (ET) are visible. Left of the tank is one of the solid rocket boosters. Workers are investigating the damage and potential problems for launch posed by ice forming in the holes, which may number as many as 150 over the entire tank. The average size of the holes is one-half inch in diameter and one-tenth inch deep. The external tank contains the liquid hydrogen fuel and liquid oxygen oxidizer and supplies them under pressure to the three space shuttle main engines in the orbiter during liftoff and ascent. The ET thermal protection system consists of sprayed-on foam insulation. The Shuttle Discovery is targeted for launch of mission STS-96 on May 20 at 9:32 a.m

At the end of its 6-hour, 4.2-mile circular trek from the Vehicle Assembly Building (background), the STS-95 Space Shuttle Discovery (barely visible behind the external tank and solid rocket boosters) is moved into place at Launch Pad 39B. To its right is the Fixed Service Structure that provides access to the orbiter and the Rotating Service Structure. Below it is the flame trench. At the launch pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the launch, scheduled to lift off Oct. 29. The mission includes research payloads such as the Spartan solar-observing deployable spacecraft, the Hubble Space Telescope Orbital Systems Test Platform, the International Extreme Ultraviolet Hitchhiker, as well as the SPACEHAB single module with experiments on space flight and the aging process.

KENNEDY SPACE CENTER, FLA. - Viewed from the top of the Vehicle Assembly Building, crowds wait in vain for the launch of the maiden flight of the Space Shuttle, “scrubbed” on April 10. Visible at center is the “V.I.P.” site, with waiting buses parked at lower right. Above are the NASA Complex 39 Press Site and viewing stands, and major news media facilities. The STS-1 mission, known as a shuttle systems test flight, will seek to demonstrate safe launch into orbit and safe return of the orbiter and crew and verify the combined performance of the entire shuttle vehicle -- orbiter, solid rocket boosters and external tank.

Moments before launch, sparks from the external ignitors are visible below the engines of Space Shuttle Columbia. The ignitors burn off a hydrogen concentration outside the orbiter near the main engines. A cloud effect behind the Shuttle's solid rocket booster and access arm to the left is created by spray from the water deluge system. The launch of STS-93 was scrubbed at the T-7 second mark in the countdown due to an indication of a high concentration of hydrogen in an aft engine compartment. The reading was proven to be a false alarm. The launch is rescheduled for July 22 at 12:28 a.m

This view was reproduced from a television transmission made by a TV camera aboard the Skylab space station in Earth orbit. The bright spot is a burn in the vidicon. The solar corona is the halo around the sun which is normally visible only at the time of solar eclipse by the moon. The Skylab coronography uses an externally-mounted disk system which occults the brilliant solar surface while allowing the fainter radiation of the corona to enter an annulus and be photographed. A mirror system allows either TV viewing of the corona or photographic recording of the image. Photo credit: NASA

KENNEDY SPACE CENTER, FLA. - Flags are flying on Launch Pad 39B at NASA Kennedy Space Center as Space Shuttle Discovery is ready on the pad for launch after rollback of the Rotating Service Structure. Visible above the External Tank is the gaseous oxygen vent arm (beanie cap). Rollback of the RSS is a major preflight milestone, typically occurring during the T-11-hour hold on L-1 (the day before launch). Discovery is scheduled to lift off on the historic Return to Flight mission STS-114 at 10:39 a.m. EDT July 26 with a crew of seven. On the mission to the International Space Station the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.

Launched on July 26, 2005 from the Kennedy Space Center in Florida, STS-114 was classified as Logistics Flight 1. Among the Station-related activities of the mission were the delivery of new supplies and the replacement of one of the orbital outpost's Control Moment Gyroscopes (CMGs). STS-114 also carried the Raffaello Multi-Purpose Logistics Module and the External Stowage Platform-2. A major focus of the mission was the testing and evaluation of new Space Shuttle flight safety, which included new inspection and repair techniques. Upon its approach to the International Space Station (ISS), the Space Shuttle Discovery underwent a photography session in order to assess any damages that may have occurred during its launch and/or journey through Space. The mission’s third and final Extra Vehicular Activity (EVA) included taking a close-up look and the repair of the damaged heat shield. Gap fillers were removed from between the orbiter’s heat-shielding tiles located on the craft’s underbelly. Never before had any repairs been done to an orbiter while still in space. This particular photo was taken by astronaut Stephen K. Robinson, STS-114 mission specialist, whose shadow is visible on the thermal protection tiles, and a portion of the Canadian built Remote Manipulator System (RMS) robotic arm and the Nile River is visible at the bottom.

This STS-113 photograph shows an incredible view of the Space Shuttle Endeavour's payload bay. The blackness of space, Earth's moon (upper right frame), and a thin slice of Earth's horizon which runs vertically across the photograph, form the back drop for this photograph. The remote manipulator system (RMS) robotic arm is visible in lower right frame. The 16th American assembly flight and 112th overall American flight to the International Space Station (ISS) launched on November 23, 2002 from Kennedy's launch pad 39A aboard the Space Shuttle Orbiter Endeavour STS-113. Mission objectives included the installation and activation of the Port 1 Integrated Truss Assembly (P1). The first major component installed on the left side of the Station, the P1 truss provides three additional External Thermal Control System radiators. Weighing in at 27,506 pounds, the P1 truss is 45 feet (13.7 meters) long, 15 feet (4.6 meters) wide, and 13 feet (4 meters) high. Three space walks, aided by the use of the Robotic Manipulator Systems of both the Shuttle and the Station, were performed in the installation of P1.

The pilot of NASAÕs X-59 Quiet SuperSonic Technology, or QueSST, aircraft will navigate the skies in a cockpit unlike any other. There wonÕt be a forward-facing window. ThatÕs right; itÕs actually a 4K monitor that serves as the central window and allows the pilot to safely see traffic in his or her flight path, and provides additional visual aids for airport approaches, landings and takeoffs. The 4K monitor, which is part of the aircraftÕs eXternal Visibility System, or XVS, displays stitched images from two cameras outside the aircraft combined with terrain data from an advanced computing system. The two portals and traditional canopy are real windows however, and help the pilot see the horizon. The displays below the XVS will provide a variety of aircraft systems and trajectory data for the pilot to safely fly. The XVS is one of several innovative solutions to help ensure the X-59Õs design shape reduces a sonic boom to a gentle thump heard by people on the ground. Though not intended to ever carry passengers, the X-59 boom-suppressing technology and community response data could help lift current bans on supersonic flight over land and enable a new generation of quiet supersonic commercial aircraft.

S81-30630 (February 1981) --- This "cutaway" artist's concept exercises some artistic license to reveal systems of the major components of a space shuttle vehicle. With its payload bay doors open here, the shuttle's cryogenic supply station (note cutaway) and the deployable radiator panels (visible) can be seen. In reality, the cargo bay panels would never be open while the orbiter is attached to the solid rocket boosters (SRB) and external fuel tank (ET). The thick-bodied, delta-winged aerospace craft is 37 meters long, has a span of 24 meters (120 feet by 80 feet), and weighs about 75,000 kilograms empty (165,000 lbs). Its payload bay, 18.3 meters long and 4.6 meters in diameter (60 feet by 15 feet) can deliver single or conglomerate payloads of up to 370 kilometers altitude or smaller loads up to 1110 kilometers (230 miles to 690 miles). It can bring payloads of 14,515 kilograms (32,000 lbs) back to Earth and it can carry out a variety of missions lasting seven to 30 days. Photo credit: NASA

KENNEDY SPACE CENTER, FLA. -- Space Shuttle Atlantis, mounted on a mobile launch platform, finally rests on the hard stand of Launch Pad 39A, straddling the flame trench. This is the second rollout for the shuttle. The flame trench transecting the pad's mound at ground level is 490 feet long, 58 feet wide and 40 feet high. It is made of concrete and refractory brick. Pad structures are insulated from the intense heat of launch by the flame deflector system, which protects the flame trench floor and the pad surface along the top of the flame trench. On the left of the shuttle are the fixed service structure and rotating service structure in open position. When closed, the rotating structure provides protected access to the orbiter for changeout and servicing of payloads at the pad. It is supported by a rotating bridge that pivots about a vertical axis on the west side of the pad's flame trench. The white area in the center is the Payload Changeout Room, an enclosed, environmentally controlled portion of the rotating service structure that supports payload delivery at the launch pad and subsequent vertical installation in the orbiter payload bay. First motion out of the Vehicle Assembly Building was at 5:02 a.m. EDT. In late February, while Atlantis was on the launch pad, Atlantis' external tank received hail damage during a severe thunderstorm that passed through the Kennedy Space Center Launch Complex 39 area. The hail caused visible divots in the giant tank's foam insulation, as well as minor surface damage to about 26 heat shield tiles on the shuttle's left wing. The shuttle was returned to the VAB for repairs. The launch of Space Shuttle Atlantis on mission STS-117 is now targeted for June 8. A flight readiness review will be held on May 30 and 31.
