The Space Shuttle program is the only United States manned space flight program. NASA’s Space Shuttle program started in 1981 and ended in 2011. NASA launched 135 space shuttle missions. A Space Shuttle is 122 feet long, weighs 240,000lbs empty, orbits at 17,320 mph, and Orbits in Low Earth Orbit (LEO) at 200 nautical miles. The space shuttle consists of the following major components: two solid rocket boosters (SRB) - critical for the launch external fuel tank (ET) - carries fuel for the launch orbiter - carries astronauts and payload
The shuttle launches Everything (not only space shuttles) that goes into the Earth orbit must curve its path on the way up. If a vehicle went straight up and did not achieve escape velocity, it would fall back to Earth after the fuel runs out. The main objective of the rocket engine is not only to get the cargo above the atmosphere, but more importantly to accelerate it in horizontal direction to the orbital speed (7.5 km/s for the orbital altitudes of the Shuttle and International Space Station). That is why all rockets / shuttles curve their path gradually to horizontal direction and then burn a lot of fuel in horizontal direction. If the cargo did not reach enough horizontal speed, it would fall back to Earth.

Casper, Pilot Curtis L. Brown, Jr., Mission Specialists Daniel W. Bursch, Mario Runco, Jr., Marc Garneau and Andrew S. W. Thomas. Image Credit: NASA Mission Highlights The fourth shuttle flight of 1996 highlighted by four rendezvous activities with two different payloads. Primary payloads, all located in the cargo bay, were the SPACEHAB-4 pressurized research module; the Inflatable Antenna Experiment (IAE) mounted on Spartan 207 free-flyer; and a suite of four technology demonstration experiments known as Technology Experiments for Advancing Missions in Space (TEAMS). More than 90 percent of the payloads were sponsored by NASA’s Office of Space Access and Technology.SPACEHAB-4 single module carried nearly 3,000 pounds (1,361 kilograms) of support equipment and variety of experiments covering such fields as biotechnology, electronic materials, polymers and agriculture, including: Advanced Separation Process for Organic Materials (ADSEP); Commercial Generic Bioprocessing Apparatus (CGBA); Plant Generic Bioprocessing Apparatus (PGBA); Fluids Generic Bioprocessing Apparatus-2 (FGBA-2); Commercial Protein Crystal Growth (CPCG); Gas Permeable Polymer Membrane (GPPM); Handheld Diffusion Test Cell (HHDTC); Commercial Float Zone Furnace (CFZF); and the Space Experiment Facility (SEF). Also considered part of SPACEHAB payload complement but located in middeck lockers were IMMUNE-3 and NIH-C7 payloads. CFZF, sponsored by NASA and the German and Canadian space agencies, was considered top priority SPACEHAB-4 payload; designed to produce large, ultra-pure crystals of such semiconductor materials as gallium arsenide. FGBA-2, an on-orbit soft-drink dispenser, required some troubleshooting, and SEF experiment declared failed when command problems with payload could not be fixed.No significant on-orbit problems with the orbiter were reported.
Spartan free-flyer deployed on flight day two using orbiter Remote Manipulator System (RMS) arm. The 132-pound (60-kilogram) IAE antenna structure, mounted on three struts, was inflated to its full size of 50 feet (15 meters) in diameter, about the size of a tennis court. Potential benefits of inflatable antennas over conventional rigid structures include their lower development costs, greater reliability, and lower mass and volume requiring less stowage space and potentially a smaller launch vehicle. Actual on-orbit performance of the antenna -- its surface smoothness -- documented with cameras and sensors for later analysis. Deploy and inflation proceeded smoothly and IAE jettisoned 90 minutes later. On flight day three, Spartan 207 pallet returned to orbiter cargo bay.Satellite deploy and rendezvous activities also conducted with Passive Aerodynamically- Stabilized Magnetically-Damped Satellite (PAMS), one of four Technology Experiments for Advancing Missions in Space (TEAMS) research payloads. TEAMS payloads located in Hitchhiker carrier in payload bay. Satellite Test Unit (STU) on PAMS deployed on flight day four. Three orbiter rendezvous conducted with satellite from a distance of 2,000-2,300 feet (610-701 meters) away to acquire satellite attitude information. STU relied on aerodynamic stabilization rather than attitude control propellants to properly orient itself. After some difficulty, Attitude Measurement System (AMS) in payload bay successfully locked onto satellite and began accurately tracking it, with initial indications showing that concept of propellant-free aerodynamic stabilization works.Other TEAMS experiments were Global Positioning System (GPS) Attitude and Navigation Experiment (GANE); Vented Tank Resupply Experiment (VTRE) and Liquid Metal Thermal Experiment (LMTE).Secondary experiments included Brilliant Eyes Ten Kelvin Sorption Cryocooler Experiment (BETSCE), an instrument designed to supercool infrared and other sensors through cyclical release and absorption of hydrogen; Aquatic Research Facility (ARF), a joint Canadian Space Agency/NASA project that allows investigation of wide range of small aquatic species, including starfish, mussels and sea urchins; Biological Research in a Canister (BRIC 07) to study endocrine functioning; Tank Pressure Control Experiment/Reduced Fill Level (TPCE/RFL) to develop pressure control for cryogenic tankage; and series of experiments flying in Get Away Special canisters.Casper spoke with Mir cosmonaut and U.S. astronaut Shannon Lucid, who was entering her 65th day aboard the Mir space station.
There are a variety of reasons for building and operating space stations, including research, industry, exploration and even tourism. The first space stations were built to study the long-term effects of weightlessness on the human body. After all, if astronauts will ever venture to Mars or other planets, then we must know how prolonged microgravity on the order of months to years will affect their healthSpace stations are a place to do cutting edge scientific research in an environment that cannot be matched on Earth. For example, gravity alters the way that atoms come together to form crystals. In microgravity, near-perfect crystals can be formed. Such crystals can yield better semi-conductors for faster computers or for more efficient drugs to combat diseases. Another effect of gravity is that it causes convection currents to form in flames, which leads to unsteady flames. This makes the study of combustion very difficult. However, in microgravity, simple, steady, slow-moving flames result; these types of flames make it easier to study the combustion process. The resulting information could yield a better understanding of the combustion process, and lead to better designs of furnaces or the reduction of air pollution by making combustion more efficient.
Multiple images of the International Space Station flying over the Houston area have been combined into one composite image to show the progress of the station as it crossed the face of the moon in the early evening of Jan. 4, 2012.

Satellites ScienceScience research satellites do much of their work at altitudes between 3,000 and 6,000 miles above Earth. Their findings are radioed to Earth as telemetry data. From 6,000 to 12,000 miles altitude, navigation satellites operate. Best known are the U.S. global-positioning system (GPS) and Russia's equivalent GLONASS satellites. The so-called Clarke Belt is the region of space 22,300 miles above Earth where satellites seem stationary above the rotating Earth. Best known occupants of the Clarke Belt are the many domestic and international TV broadcast, weather reporting and communications satellites. Non-BroadcastersInmarsats are examples among many non-broadcast communications satellites in the Clarke Belt. Europe's Meteosat and America's GOES are weather satellites in stationary orbits. At the same altitudes, but less-well known, are satellites such as NASA's TDRS (Tracking and Data Relay Satellites), Russia's similar Satellite Data Relay Network (SDRN), U.S. Milstar military communications satellites, the Pentagon's Defense Satellite Communications System (DSCS) and the U.S. Navy's Fltsatcom and Ultra High Frequency (UHF) communications satellites. The Russians have a series of communications satellites, known as Molniya, in long elliptical orbits which repeatedly carry them out beyond 22,000 miles before they swing back to within 1,000 miles of Earth's surface. Molniyas relay television broadcasts as well as man-in-space and military communications. Other satellites in such elliptical orbits range from as close as 250 miles out to 60,000 miles. They include intelligence-agency communications craft and early-warning satellites which would report a launch of nuclear weapons.
