Space Shuttle
The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft where it was the only item funded for development. The first ( STS-1) of four orbital test flights occurred in 1981, leading to operational flights ( STS-5) beginning in 1982. Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011. They launched from the Kennedy Space Center (KSC) in Florida. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST), conducted science experiments in orbit, participated in the Shuttle-''Mir'' program with Russia, and participated in construction and servicing of the International Space Station (ISS ...

Space Shuttle External Tank
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine cut-off (MECO) and it re-entered the Earth's atmosphere. Unlike the Solid Rocket Boosters, external tanks were not re-used. They broke up before impact in the Indian Ocean (or Pacific Ocean in the case of direct-insertion launch trajectories), away from shipping lanes and were not recovered. Overview The ET was the largest element of the Space Shuttle, and when loaded, it was also the heaviest. It consisted of three major components: * the forward liquid oxygen (LOX) tank * an unpressurized intertank that contains most of the electrical components * the aft liquid hydrogen (LH2) tank; this was the largest part, but it was relativel ...

Hurricane Fran
Hurricane Fran caused extensive damage in the United States in early September 1996. The sixth named storm, fifth hurricane, and third major hurricane of the 1996 Atlantic hurricane season, Fran developed from a tropical wave near Cape Verde on August 23. Due to nearby Hurricane Edouard, the depression remained disorganized as it tracked westward, though it eventually intensified into Tropical Storm Fran on August 27. While heading west-northwestward, Fran steadily strengthened into a hurricane on August 29, but weakened back to a tropical storm on the following day. On August 31, Fran quickly re-intensified into a hurricane. By September 2, Fran began to parallel the islands of the Bahamas and slowly curved north-northwestward. Early on September 5, Fran peaked as a Category 3 hurricane. Thereafter, Fran weakened slightly, before it made landfall near Cape Fear, North Carolina early on September 6. The storm rapidly weakened inland and was only a tropical depression later that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Bertha (1996)
Hurricane Bertha was an intense and early-forming major hurricane that affected areas from the Leeward Islands to the United States in July of the 1996 Atlantic hurricane season. The second named storm, first hurricane, and first major hurricane during the season. Bertha originated from a tropical wave that moved off the coast of Africa in early July. Steadily organizing while moving generally towards the west, the disturbance was designated as a tropical depression at 0000 UTC on July 5, and was further upgraded to a tropical storm by 1200 UTC later that day. Over the next few days, continued intensification occurred, and Bertha became a Category 1 hurricane on the Saffir-Simpson hurricane scale, the first hurricane of the season, prior to moving through the northern Leeward Islands. Late on July 8, a period of rapid intensification began, and at 0600 UTC on July 9, Bertha reached its peak intensity with maximum sustained winds of with a minimum barometric pressure of . Movi ...

STS-79
STS-79 was the 17th flight of Space Shuttle ''Atlantis'', and the 79th mission of the Space Shuttle program. The flight saw ''Atlantis'' dock with the Russian space station Mir to deliver equipment, supplies and relief personnel. A variety of scientific experiments were also conducted aboard ''Atlantis'' by her crew. It was the first shuttle mission to rendezvous with a fully assembled Mir, and the fourth rendezvous of a shuttle to the space station. Crew Mission highlights STS-79 was the first shuttle mission to a fully completed Mir space station, following the arrival of its Priroda module. ''Atlantis'' carried the Orbiter Docking System. This spaceflight was highlighted by the collection of American astronaut Shannon Lucid after 188 days in space, the first American crewmember exchange aboard the Russian Space Station Mir, and the fourth Shuttle-Mir docking. Lucid's long-duration spaceflight set a new American record, as well as worldwide spaceflight record for a woman as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Erin (1995)
Hurricane Erin was the first hurricane to strike the contiguous United States since Hurricane Andrew in 1992. The fifth tropical cyclone, fifth named storm, and second hurricane of the unusually active 1995 Atlantic hurricane season, Erin developed from a tropical wave near the southeastern Bahamas on July 31. Moving northwestward, the cyclone intensified into a Category 1 hurricane on the Saffir–Simpson scale near Rum Cay about 24 hours later. After a brief jog to the north-northwest on August 1, Erin began moving to the west-northwest. The cyclone then moved over the northwestern Bahamas, including the Abaco Islands and Grand Bahama. Early on August 2, Erin made landfall near Vero Beach, Florida, with winds of 85 mph (140 km/h). The hurricane weakened while crossing the Florida peninsula and fell to tropical storm intensity before emerging into the Gulf of Mexico later that day. Early on August 3, Erin re-intensified into a Category& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-69
STS-69 was a Space Shuttle ''Endeavour'' mission, and the second flight of the Wake Shield Facility (WSF). The mission launched from Kennedy Space Center, Florida on 7 September 1995. It was the 100th successful crewed NASA spaceflight, not including X-15 flights.

Northern Flicker
The northern flicker or common flicker (''Colaptes auratus'') is a medium-sized bird of the woodpecker family. It is native to most of North America, parts of Central America, Cuba, and the Cayman Islands, and is one of the few woodpecker species that migrate. Over 100 common names for the northern flicker are known, including yellowhammer (not to be confused with the Eurasian yellowhammer (''Emberiza citrinella'')), clape, gaffer woodpecker, harry-wicket , heigh-ho, wake-up, walk-up, wick-up, yarrup, and gawker bird. Many of these names derive from attempts to imitate some of its calls. It is the state bird of Alabama (known by its colloquial name "yellowhammer.") Taxonomy The English naturalist Mark Catesby described and illustrated the northern flicker in his book ''The Natural History of Carolina, Florida and the Bahama Islands'' which was published between 1729 and 1732. Catesby used the English name "Gold-winged Wood-pecker" and the Latin ''Picus major alis aureis''. W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-70
STS-70 was the 21st flight of the Space Shuttle ''Discovery'', and the last of 7 shuttle missions to carry a Tracking and Data Relay Satellite (TDRS). This was the first shuttle mission controlled from the new mission control center room at the Johnson Space Center in Houston. STS-70 was also the first flight of the new Block 1 orbiter main engine, designed to improve both engine performance and safety. The mission was launched from Kennedy Space Center in Florida on 13 July 1995, only six days after the landing of sister ship ''Atlantis'', marking the fastest turnaround between flights in the history of the program. Crew Preparations and Launch STS-70 had originally moved ahead of STS-71 because of a delay in the launch of the Russian Spektr laboratory module to the Russian space station Mir. However, on 31 May 1995 shuttle managers assessed damage to the External Tank of STS-70 caused by nesting flicker woodpeckers. The damage consisted of about 71 holes (ranging in size f ...

Space Shuttle Endeavour
Space Shuttle ''Endeavour'' ( Orbiter Vehicle Designation: OV-105) is a retired orbiter from NASA's Space Shuttle program and the fifth and final operational Shuttle built. It embarked on its first mission, STS-49, in May 1992 and its 25th and final mission, STS-134, in May 2011. STS-134 was expected to be the final mission of the Space Shuttle program, but with the authorization of STS-135 by the United States Congress, ''Atlantis'' became the last shuttle to fly. The United States Congress approved the construction of ''Endeavour'' in 1987 to replace the Space Shuttle ''Challenger'', which was destroyed in 1986. NASA chose, on cost grounds, to build much of ''Endeavour'' from spare parts rather than refitting the Space Shuttle ''Enterprise'', and used structural spares built during the construction of '' Discovery'' and ''Atlantis'' in its assembly. History Following the loss of ''Challenger'', in 1986 NASA was authorized to begin the procurement process for a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-39
STS-39 was the twelfth mission of the NASA Space Shuttle ''Discovery'', and the 40th orbital shuttle mission overall. The primary purpose of the mission was to conduct a variety of payload experiments for the U.S. Department of Defense (DoD). Crew Crew seating arrangements Mission highlights Launch was originally scheduled for March 9, 1991, but during processing work at Pad LC-39A, significant cracks were found on all four lug hinges on the two external tank umbilical door drive mechanisms. NASA managers opted to roll back the vehicle to the Vehicle Assembly Building (VAB) on March 7, 1991, and then to Orbiter Processing Facility (OPF) for repair. The faulty hinges were replaced with units taken from orbiter ''Columbia'', and reinforced. ''Discovery'' was returned to the pad on April 1, 1991, and the launch was rescheduled for April 23. The mission was again postponed when, during prelaunch external tank loading, a transducer on high-pressure oxidizer turbopump ...
