STS056-S-002 (January 1993) --- The five NASA astronauts assigned to fly aboard the Space Shuttle Discovery for the STS-56\Atlas-2 mission are pictured in training versions of their partial-pressure launch and entry garments. Left to right are astronauts Kenneth D. Cockrell, Steven S. Oswald, C. Michael Foale, Kenneth D. Cameron and Ellen Ochoa. Cameron is mission commander; Oswald, pilot; while the other three will serve as mission specialists.

STS-56 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, is of the Strait of Gibraltar. A small bank of clouds marks the passage between Spain and Morocco at the western edge of the Mediterranean Sea. This passage, one of the two Pilars of Hercules of the Ancient Greeks, is now known as the Strait of Gibraltar. The cities of Cadiz on the Atlantic Coast of Spain and Malaga on the Mediterranean coast, as well as Tangier, Morocco (facing the strait), can be seen. According to NASA scientists studying the STS-56 photos, a subtle difference in the water color on the Atlantic side suggests that a pulse of surface water had recently flowed out of the Mediterranean into the Atlantic.

STS056-S-001 (January 1993) --- The patch is a pictorial representation of the STS-56/ATLAS-2 mission as seen from the crew's viewpoint. The payload bay is depicted with the ATLAS-2 pallet, Shuttle Solar Backscatter Ultra Violet (SSBUV) experiment, and Spartan -- the two primary scientific payloads on the flight. With ATLAS-2 serving as part of the "Mission to Planet Earth" (MTPE) project, the crew has depicted the planet prominently in the artwork. Two primary areas of study are the atmosphere and the sun. To highlight this, Earth's atmosphere is depicted as a stylized visible spectrum and the sunrise is represented with an enlarged two-colored corona. Surnames of the commander and pilot are inscribed in the Earth field, with the surnames of the mission specialists appearing in the space background. The NASA insignia design for space shuttle flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which we do not anticipate, it will be publicly announced. Photo credit: NASA

STS-56 Earth observation of the northeastern Nile Delta was photographed from the Earth-orbiting Discovery, Orbiter Vehicle (OV) 103. The branch of the Nile featured in the frame is Daimietta. The Suez Canal marks the boundary of the Nile Delta agriculture and the Sinai Desert to the right. Lake Masada, the dark waterlogged area to the west (left) of Port Said is becoming more saline as the Aswan Dam has reduced sediment downstream. This sediment reduction, according to NASA scientists studying the STS-56 photography, has resulted in increased coastal erosion and the intrusion of a salt-water lens to the ground water, particularly in the northeastern portions of the delta. Center pivot irrigation fields are located along either side of the Ramses Canal, which connects the Daimietta Nile with Great Bitter Lake. This canal has been re-dug three or four times in the past 3,000 years. Historians note that the canal's most famous use was as the departure point of the fleet of Pharaoh Necho. The fleet circumnavigated Africa clockwise from the head of the Red Sea to the Mediterranean coast of the Nile (probably the Rosetta Nile) in a three-year voyage circa 660 BC.

During STS-56, the Shuttle Pointed Autonomous Research Tool for Astronomy 201 (SPARTAN-201), a freeflying payload, was photographed by Discovery's, Orbiter Vehicle (OV) 103's, crewmembers as it drifted above the Mediterranean Sea near the island of Crete. On the mission's third day, the remote manipulator system (RMS) arm was used to lift SPARTAN-201 from its support structure in OV-103's payload bay and release it in space. SPARTAN-201 was later recaptured by OV-103's RMS and returned to Earth with the astronaut crew.

STS-56 Earth observation taken aboard Discovery, Orbiter Vehicle (OV) 103, is probably the best view of Perth in Western Australia. (For orientation purposes, note that the coastline runs north and south). The major feature on the coast is the large estuary of the Swan River. The large port city of Perth is situated on the north bank and the smaller city of Freemantle on the south bank by the sea. Smaller seaside towns trail off north and south of this center of urban life. Inland lies a prominent escarpment, more than 600 feet high, seen running down the middle of the view and dividing the lighter-colored coastal lowlands from the highlands where dark-colored tree savanna and desert scrub dominates the land. The Moore River can be seen entering the sea at the top of the frame. Rottnest Island is visible in the sea and Garden Island near bottom edge of the frame. Perth is the largest economic center in Western Australia. It receives natural gas from an offshore field hundreds of miles to the north. It lies 3,400 kilometers west of Sydney on the opposite side of this island continent.

Space Shuttle Discovery (STS-56) Mission Specialist 3 (MS3) Ellen Ochoa handles a 35mm camera on the aft flight deck of the Orbiter. Ochoa is positioned next to the payload station and behind the commander's station.

STS-56 Earth observation shows of some of the highest mountain peaks in the world taken from Discovery, Orbiter Vehicle (OV) 103, as it passed over India and China. The top of the view shows one of the snow and ice-covered massifs in the great Karakorum Range of north India. A star-shaped peak at top left reaches 23,850 feet. Glaciers can be seen in valleys at these high elevations. The international border between India to the south (top) and China (bottom) snakes left to right along a river near the top of the scene, then veers into the muntains at top left. Larger valleys, despite their elevation (all in excess of 14,000 feet), are occupied by transport routes joining points in India, China and the southern republics of the CIS. The ancient Silk Route between China and the Middle East lies not far to the north (outside the bottom of the frame).

The second try works like a charm as the Space Shuttle Discovery (STS-56) lifts off from Launch Pad 39B. The first attempt to launch was halted at T-11 seconds on April 6th. Aboard for the second shuttle mission of 1993 were a crew of five and the Atmospheric Laboratory for Applications and Science 2 (ATLAS 2), the second in a series of missions to study the sun's energy output and Earth's middle atmosphere chemical make-up, and how these factors affect levels of ozone.

The ATLAS program was designed to measure the long term variability in the total energy radiated by the sun and determine the variability in the solar spectrum.

During STS-56, the Shuttle Pointed Autonomous Research Tool for Astronomy 201 (SPARTAN-201), a freeflying payload, was captured on 70mm film as it drifts over the Red Sea coast of Sudan. SPARTAN-201 was photographed by the crewmembers aboard Discovery, Orbiter Vehicle (OV) 103. On the mission's third day, crewmembers used the remote manipulator system (RMS) to lift the satellite from its support structure in OV-103's payload bay (PLB) and release it into space. SPARTAN-201 was later recaptured by OV-103's RMS and returned to Earth with the astronaut crew. The cape structure in the background is Ras abu Shagara, north of Port Sudan.

Oswald, wearing launch and entry suits (LESs), stand at the side hatch of the crew compartment trainer (CCT), a shuttle mockup, prior to entering the mockup. Once inside the CCT, they will don their launch and entry helmets (LEHs) and participate in emergency egress (bailout) procedures. The CCT is located in JSC's Mockup and Integration Laboratory (MAIL) Bldg 9NE.

Space Shuttle Discovery (STS-56) onboard photo of Pilot Stephen S. Oswald (wearing a headset) uses the Shuttle Amateur Radio Experiment II (SAREX-II) while sitting at the pilot's station on the forward flight deck. Oswald smiled from behind the microphone as he talks to amateur radio operators on Earth via the SAREX equipment. SAREX cables and the interface module freefloat in front of Oswald. The anterna located in the forward flight deck window is visible in the background. SAREX was established by NASA, the American Radio League/Amateur Radio Satellite Corporation and the Johnson Space Center (JSC) Amateur Radio Club to encourage public participation in the space program through a program to demonstrate the effectiveness of conducting short-wave radio transmissions between the Shuttle and ground-based radio operators at low-cost ground stations with amateur and digital techniques.

The STS-56 crew portrait includes five astronauts. Seated from the left are Stephen S. Oswald, pilot; and Kenneth D. Cameron, commander. Standing, from the left, are mission specialists Kenneth D. Cockrell, C. Michael Foal, and Ellen Ochoa. The crew launched aboard the Space Shuttle Discovery on April 8, 1993 at 1:29:00 am (EDT) with the Atmospheric Laboratory for Applications and Science-2 (ATLAS-2) as the primary payload.

STS056-90-034 (8-17 April 1993) --- Backdropped against heavy cloud cover over the Mediterranean Sea, the SPARTAN-201 satellite was captured on 70mm by crewmembers aboard the Space Shuttle Discovery. SPARTAN is a free-flying payload designed to study the solar wind and part of the sun's corona. The project was conceived in the late 1970s to take advantage of the opportunity offered by the Space Shuttle to provide more observation time for the increasingly more sophisticated experiments than the five to ten minutes provided by sounding rocket flights. On the mission's third day, Astronaut Ellen Ochoa, Mission Specialist, used the remote manipulator system (RMS) to lift the satellite from its support structure on Discovery and release it in space. The reusable craft was later recaptured and returned to Earth with the crew. Note the tip of Discovery's vertical stabilizer at frame's edge.

STS056-S-098 (17 April 1993) --- The drag chute is deployed following landing of the Space Shuttle Discovery on the Shuttle landing facility at the Kennedy Space Center to complete the STS-56\Atlas 2 mission. Touchdown occurred at 7:37 a.m. (EDT). Onboard the spacecraft were astronauts Kenneth D. Cameron, commander; Stephen S. Oswald, pilot; and C. Michael Foale, Ellen Ochoa and Kenneth D. Cockrell, mission specialists.

STS056-S-080 (13 April 1993) --- Astronauts Kevin P. Chilton (left) and Curtis L. Brown Jr. are seen at the spacecraft communicator (CAPCOM) console in the flight control room of Houston's Mission Control Center (MCC). The two are part of the CAPCOM team who communicated with the five crewmembers aboard Discovery for the STS-56 mission in Earth orbit.

KENNEDY SPACE CENTER, FLA. -- STS-56: Discovery

STS056-08-018 (8-17 April 1993) --- Aboard Discovery, astronaut Kenneth D. Cockrell, mission specialist, records Earth imagery with the Hand-Held, Earth-Oriented, Real-Time, Cooperative, User-Friendly, Location-Targeting and Environmental System (HERCULES). HERCULES is a device that makes it simple for Shuttle crew members to take pictures of Earth, as they merely point a modified 35mm camera and shoot any interesting feature, whose latitude and longitude are automatically determined in real-time. The powder-box shaped attachment is the Inertial Measurement Unit (IMU) for the system. The STS-56 crew downlinked a number of the still images during the flight, while others are likely to be stored on disc and returned to Earth with the crew.

STS-56 Discovery, Orbiter Vehicle (OV) 103, riding atop its external tank (ET) and flanked by two solid rocket boosters (SRBs), lifts off from Kennedy Space Center (KSC) Launch Complex (LC) Pad 39B into the early morning darkness at 1:29 am (Eastern Daylight Time (EDT)). In this nocturnal scene, OV-102's nose section is obscured in the shadowy darkness as it clears the fixed service structure (FSS) tower. Exhaust plumes trail from the SRB skirts and cover the launch pad area in a billowy cloud. The SRB / Space Shuttle Main Engine (SSME) firings illuminate the FSS and the retracted rotating service structure (RSS). Debris is visible on the base of the launch pad.

S92-31007 (March 1992) --- Astronaut Stephen S. Oswald.

STS056-91-050 (8-17 April 1993) --- This 70mm frame shows the cargo bay of the Earth-orbiting Space Shuttle Discovery backdropped against clouds. Most of the elements of the ATLAS-2 payload can be seen, but missing is the SPARTAN-201 satellite which was in the midst of its separation from Discovery when the photo was made.
