This is a Microgravity Science Laboratory-1 (MLS-1) onboard STS-83 photo of the most recent comet to date, Hale-Bopp, which passed by Earth during the spring and summer of 1997. In this view, the comet is visible during sunset. The streaks and distorted lights seen in the bottom of the photo are city lights and petroleum fires.

The crew patch for NASA's STS-83 mission depicts the Space Shuttle Columbia launching into space for the first Microgravity Sciences Laboratory 1 (MSL-1) mission. MSL-1 investigated materials science, fluid dynamics, biotechnology, and combustion science in the microgravity environment of space, experiments that were conducted in the Spacelab Module in the Space Shuttle Columbia's cargo bay. The center circle symbolizes a free liquid under microgravity conditions representing various fluid and materials science experiments. Symbolic of the combustion experiments is the surrounding starburst of a blue flame burning in space. The 3-lobed shape of the outermost starburst ring traces the dot pattern of a transmission Laue photograph typical of biotechnology experiments. The numerical designation for the mission is shown at bottom center. As a forerunner to missions involving International Space Station (ISS), STS-83 represented the hope that scientific results and knowledge gained during the flight will be applied to solving problems on Earth for the benefit and advancement of humankind.

Five NASA astronauts and two scientists comprised the crew for the STS-83 mission in support of the first Microgravity Sciences Laboratory 1 (MSL-1). Pictured on the front row (left to right) are Janice E. Voss, payload commander; James D. Halsell, commander; Susan L. Still, pilot; and Donald A. Thomas, mission specialist. On the back row (left to right) are payload specialists Roger K. Crouch, and Gregory T. Linteris; and Michael L. Gernhardt, mission specialist. Dr. Crouch and Dr. Linteris are experts in several disciplines treated on MSL-1. STS-83 launched aboard the Space Shuttle Columbia on April 4, 1997. The five launched again in July 1997 for the STS-94 mission.

The soon-to-be-spaceborne Space Shuttle Columbia gets a flyby visit from the Comet Hale-Bopp (shown as the streak at left center) while awaiting launch on the STS-83 mission. This photo was taken the night before the planned liftoff on April 4, 1997. The Rotating Service Structure at Launch Pad 39A has been moved back prior to the start of operations to fuel the external tank. The primary objective of the STS-83 flight is to operate the Microgravity Science Laboratory-1 (MSL-1), which will test some of the hardware, facilities and procedures that will be used on the International Space Station.

STS083-712-063 (4-8 April 1997) --- Northern half of Long Island, Bahamas. The vivid blues of the Bahamas stand out from space. Long Island and Great Exuma Island, which extends from the west north west into the photo, is on the eastern side of the Great Bahama Bank and form the borders of Exuma Sound. This photograph provides a rare opportunity to observe a natural chemical laboratory at work. Limestone of quite a different sort from that forming the Great Barrier Reef is actually in the process of formation. Long Island itself is little more than a sandbar rising just a few meters (about 30 to 50 meters) above sea level but it separates the deep, dark blue waters of the Atlantic on the right from the 10-meter (33 feet) shallows of the Great Bahama Bank (left). Details of the topography of the bank are visible through the clear waters. The shallow waters are warm and become extremely salty. Crystals of aragonite, a calcium carbonate mineral, are precipitated and formed into spherical sand-sized oolites as the tidal currents swirl back and forth. Lithification of the carbonate sands produces an oolithic limestone. Although the water is warm and clear, corals do not live in the shallows, probably because of the elevated salt content. Although chemically similar, the oolithic limestone forming Long Island is very different from coral reef limestone. An airfield is visible at the northern and central (bottom of photo) part of the island.

S97-02820 (17 Dec. 1996) --- Astronaut Janice Voss, mission specialist.

STS083-712-068 (4-8 April 1997)--- This is a thunderstorm cell that towers above the surrounding cloud deck and is illuminated by the last rays of the setting sun.

STS083-749-084 (4-8 April 1997) --- Laguna Oja De Liebre, Baja, gray whale breeding ground Laguna Oja De Liebre, Baja (Scammons Lagoon) is located on the west coast in the plains of the central Baja. This lagoon and others like it along the Baja coast are used for breeding grounds for the gray whale. One group of gray whales inhabits the Sea of Okhotsk in summer, migrating south in winter then breed off southern Korea. The other summers in the Bering and Chukchi seas and travels south to winter breeding grounds along the coast of Baja California. The gray whale was hunted almost to extinction by 1925 but was placed under complete international protection and since the 1940s has increased in numbers. The white grids seen in the photo are commercial salt ponds.

STS083-747-026 (4-8 April 1997) --- Aswan Dam and Lake Nasser along the Nile River, Egypt. The Aswan Dam controls the flow of the Nile River forming Lake Nasser. Lake Nasser is reaching relatively high water levels due to the plentiful rains since December 1996 in Kenya, near the headwaters of the Nile river. The light colored areas in the Lake are where the sun is reflecting off the surface of the water. These areas are fairly calm and not disturbed by wind gusts enabling the sunglint to show water current patterns on the surface. The Aswan runway is seen as a dark set of lines west of the Aswan Dam.

STS083-747-052 (4-8 April 1997) --- Sunglint on the Indus River, Sukkar, and Rohri, Pakistan. Sukkar city (27.42 north 68.52 east), Sindh province, southeastern Pakistan lies on the west bank of the Indus River, connected with Rohri on the opposite bank by a cantilever bridge. Midstream between the two cities is the strategic island fortress of Bukkur. The old town contains many historic tombs and mosques, including the Mir Ma'sum Shah Minaret (c. AD 1607). An industrial and trade center, it has biscuit, cigarette, oil, lime, and cement factories, and cotton, silk, thread, and flour mills; boat building is also significant. The surrounding region is a vast alluvial plain broken only occasionally by low limestone hills. A portion of the Thar Desert is reaching from the south to Rohri. The Sukkur Barrage, highlighted by the sunglint, was completed in 1932. Nearly 1 mile (1.6 kilometers) long it crosses the Indus River 3 miles (4.8 kilometers) below Sukkur Gorge and feeds irrigation canals. The canals originating from it serve a cultivable area of about five million acres of land producing both food and cash crops, such as wheat, cotton, rice, oilseed, and fruit cultivation.

STS083-748-006 (4-8 April 1997) --- This type of scene is seen about every 45 minutes as the astronauts travel around the world. Sunrises and sunsets differ in structure, since the tropopause altitude and atmospheric lamina temperatures vary with time of day, season, and latitude. Close analysis of these terminator photographs provide counts of the number and spacing of atmospheric laminae. In the photographs, as many as 4 laminae have been noted in the normally red-to-orange troposphere, and up to 12 laminae have been counted in the blue upper atmosphere. However, true replication of human vision is not possible using present films. For instance, while on orbit, one astronaut counted 22 layers. The photograph of that event recorded only 8 such layers.

STS083-747-088 (4-8 April 1997)--- Mayon Volcano with a Plume, Luzon, the Philippines Mayon has the classic conical shape of a strato volcano. It is the most active volcano in the Philippines and continues to be active as demonstrated by the plume in the photo. Since 1616, Mayon has erupted 47 times. The most recent major eruption, in 1993, began unexpectedly with an explosion. The initial eruption lasted only 30 minutes but it generated pyroclastic flows that killed 68 people and prompted the evacuation of 60,000 others.

STS083-747-033 (4-8 April 1997) --- Center Pivot Irrigation, in Saudi Arabia. This irrigation project in Saudi Arabia is typical of many isolated irrigation projects scattered throughout the arid and hyper-arid regions of the Earth. Fossil water is mined from depths as great as 3,000 feet, pumped to the surface, and distributed via large center pivot irrigation feeds. The circles of green irrigated vegetation may comprise a variety of agricultural commodities from alfalfa to wheat. Diameters of the normally circular fields range from a few hundred meters to as much as 2 miles. The projects often trace out a narrow, sinuous, and seemingly random path. Actually, engineers generally seek ancient river channels now buried by the sand seas. The fossil waters mined in these projects accumulated during periods of wetter climate in the Pleistocene glacial epochs, between 10,000 to 2 million years ago, and are not being replenished under current climatic conditions. The projects, therefore, will have limited production as the reservoirs are drained. Water, of course, is the key to agriculture in Saudi Arabia. The Kingdom has implemented a multifaceted program to provide the vast supplies of water necessary to achieve the spectacular growth of the agricultural sector. A network of dams has been built to trap and utilize precious seasonal floods. Vast underground water reservoirs have been tapped through deep wells. Desalination plants have been built to produce fresh water from the sea for urban and industrial use, thereby freeing other sources for agriculture. Facilities have also been put into place to treat urban and industrial run-off for agricultural irrigation. These efforts collectively have helped transform vast tracts of the desert into fertile farmland. Land under cultivation has grown from under 400,000 acres in 1976 to more than 8 million acres in 1993.

STS083-749-079 (4-8 April 1997) --- Cloud wake covers the Leeward Islands. Like a ship making a wake in the water, Guadeloupe Island is making a wake in the clouds. Seeing certain weather features tells us information as to what the conditions were at the time the photo was taken. For instance, a solid cloud area is formed behind the island in this photo so the winds are under or at 5 meters per second (mps). If the winds were greater Von Karman Vortices would develop. Formation of Von Karman Vortices requires wind speeds of 5 and 13 mps and a strong low level temperature inversion below the highest peak of the island.

STS083-748-066 (4-8 April 1997) --- Luxor, Qus, and Qina, Egypt on the Nile. The Nile, which is about 4,132 miles long, is the longest river in the world. This photo demonstrates the dependency of the local agriculture on the River. This area is the historic area of ancient Thebes. Luxor, also called EL-AKSUR, or AL-UQSUR, a market town along the southern part of the Nile's curve, is located on the southern half of the ruins of Thebes. Ancient Thebes was about six miles square; the main part of the city was situated along the Nile's east bank; along the west bank was "the city of the dead" -- an area containing the Egyptian kings' mortuary temples and the houses of those priests, soldiers, craftsmen, and laborers who were devoted to their service. Qina, extending 3 - 4 miles (5 - 6 kilometers) on each side of the Nile River between the Arabian and Libyan deserts, is seen on the northeast part of the rivers curve. Occupying the great bend in the Nile Valley, it has an area of 715 square miles (1,851 square kilometers) and contains the celebrated ruins of Thebes and the Valley of the Tombs of the Kings. Qina has a dense agricultural population (more than 3,000 persons per square mile), and most of its land is under basin irrigation, yielding only one crop annually. Main crops are sugar (about three-fifths of the nation's production), lentils, and grains.

KENNEDY SPACE CENTER, FLA. -- STS-83 Pilot Susan L. Still greets KSC postlanding operations workers on Runway 33 at the Space Center’s Shuttle Landing Facility after the Space Shuttle Orbiter Columbia landed at 2:33:11 p. m. EDT, April 8, to conclude the Microgravity Science Laboratory-1 (MSL-1) mission. At main gear touchdown, the STS-83 mission duration was 3 days, 23 hours, 12 minutes. The planned 16-day mission was cut short by a faulty fuel cell. This is only the third time in Shuttle program history that an orbiter was brought home early due to mechanical problems. This was also the 36th KSC landing since the program began in 1981

STS083-312-031 (4-8 April 1997) --- Payload specialist Gregory T. Linteris (left) is seen at the Mid Deck Glove Box (MGBX), while astronaut Donald A. Thomas, mission specialist, works at the Expedite the Processing of Experiments to Space Station (EXPRESS) rack. MGBX is a facility that allows scientists the capability of doing tests on hardware and materials that are not approved to be handled in the open Spacelab. It is equipped with photographic, video and data recording capability, allowing a complete record of experiment operations. Experiments performed on STS-83 were Bubble Drop Nonlinear Dynamics and Fiber Supported Droplet Combustion. EXPRESS is designed to provide accommodations for Sub-rack payloads on Space Station. For STS-83, it held two payloads. The Physics of Hard Colloidal Spheres (PHaSE) and ASTRO-Plant Generic Bioprocessing Apparatus (ASTRO-PGBA), a facility with light and atmospheric controls which supports plant growth for commercial research.

Parvalbumins are found in the muscles, endocrine glands, skin cells, and some neurons of vertebrates, but the role they play for musculature is not yet understood. Researchers are exploring theories of a correlation between parvalbumin concentration levels and the relaxation speed of mammalian muscles after contraction. An ultra-high resolution structure was achieved from samples grown on STS-83 and in July 1997, during STS-94, PCAM produced the largest crystals of pike parvalbumin grown to date. Principal Investigator: Dan Carter of New Century Pharmaceuticals.

The Space Shuttle Orbiter Columbia is reflected in a nearby pond as it rolls over to the Vehicle Assembly Building (VAB) June 4 from Orbiter Processing Facility (OPF) 1 atop its transporter in preparation for the STS-94 mission. Once inside the VAB, Columbia will be hoisted to be mated with its solid rocket boosters and external tank. Columbia was moved to the OPF April 8 after the completion of the STS-83 mission. KSC payloads processing employees then began work to reservice the Microgravity Science Laboratory-1 (MSL-1) Spacelab module in the orbiter’s payload bay for the STS-94 mission. This was the first time that this type of payload was reserviced without removing it from the payload bay. This new procedure pioneers processing efforts for possible quick relaunch turnaround times for future payloads. The MSL-1 module will fly again with the full complement of STS-83 experiments after that mission was cut short due to indications of a faulty fuel cell. During the scheduled 16-day STS-94 mission, the experiments will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station while the flight crew conducts combustion, protein crystal growth and materials processing experiments

KSC payload processing employees in Orbiter Processing Facility 1 prepare the Space Shuttle Orbiter Columbia’s crew airlock and payload bay for the reinstallation of the Spacelab long transfer tunnel that leads from the airlock to the Microgravity Science Laboratory-1 (MSL-1) Spacelab module. The tunnel was taken out after the STS-83 mission to allow better access to the MSL-1 module during reservicing operations to prepare it for for the STS-94 mission. That space flight is now scheduled to lift off in early July. This was the first time that this type of payload was reserviced without removing it from the payload bay. This new procedure pioneers processing efforts for quick relaunch turnaround times for future payloads.

Yesterday, NASA decided to postpone for 24-hours the launch of Columbia on mission STS-83 due to a requirement to add additional thermal insulation to water coolant lines in the orbiter's payload bay. The water coolant lines are seen here winding their way around the window on the left. Managers determined that the lines, which cool various electronics on the orbiter, were not properly insulated and could possibly freeze during Columbia's 16-days in space. Columbia's launch is now set for 2:00 p.m. EST on Friday, April 4, 1997

KENNEDY SPACE CENTER, Fla. -- The Space Shuttle Orbiter Columbia begins its rollout from the Vehicle Assembly Building to Launch Pad 39A in preparation for the STS-83 mission. The Microgravity Science Laboratory-1 (MSL-1) Spacelab module is the primary payload on this 16-day spaceflight. The MSL-1 will be used to test some of the hardware, facilities and procedures that are planned for use on the International Space Station, while the seven-member flight crew conducts combustion, protein crystal growth and materials processing experiments

Apollo 7 Commander Walter M. "Wally" Schirra and his wife, Josephine, were among the many special NASA STS-83 launch guests who witnessed the liftoff of the Space Shuttle Columbia April 4 at the Banana Creek VIP Viewing Site at KSC. Columbia took off from Launch Pad 39A at 2:20:32 p.m. EST to begin the 16-day Microgravity Science Laboratory-1 (MSL-1) mission

STS084-389-024 (15-24 May 1997) --- Comet Hale Bopp, seen and photographed a month and a half ago by the STS-83 crew aboard the Space Shuttle Columbia, was also visible on this mission and the crew took advantage of several photo opportunities. A crewmember used an eight-second time exposure on a 35mm camera to expose this frame of the comet over Earth's horizon. Streaking of the stars, usually associated with time exposures, was avoided due to Space Shuttle Atlantis' inertial attitude with the stars.
