What best describes how NASA's Kennedy Space Center benefits Florida?

Answer 1

The National Aeronautics and Space Administration(NASA) is the agency of the United States government that is responsible for the nation's civilian space program and for aeronautics and aerospace research. Since February 2006, NASA's mission statement has been to "pioneer the future in space exploration, scientific discovery and aeronautics research." [5] On September 14, 2011, NASA announced that it had selected the design of a new Space Launch System that it said would take the agency's astronauts farther into space than ever before and provide the cornerstone for future human space exploration efforts by the U.S.[6][7][8]

NASA was established by the National Aeronautics and Space Act on July 29, 1958, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA). The agency became operational on October 1, 1958.[9][10] U.S. space exploration efforts have since been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.

NASA science is focused on better understanding Earth through the Earth Observing System,[11] advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program,[12] exploring bodies throughout the Solar System with advanced robotic missions such as New Horizons,[13] and researching astrophysics topics, such as the Big Bang, through the Great Observatories and associated programs.[14] NASA shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite.

From 1946, the NACA had been experimenting with rocket planes such as the supersonic Bell X-1.[15] In the early 1950s, there was challenge to launch an artificial satellite for the International Geophysical Year (1957-58). An effort for this was the American Project Vanguard. After the Soviet launch of the world's first artificial satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. The U.S. Congress, alarmed by the perceived threat to national security and technological leadership (known as the "Sputnik crisis"), urged immediate and swift action; President Dwight D. Eisenhower and his advisers counseled more deliberate measures. This led to an agreement that a new federal agency mainly based on NACA was needed to conduct all non-military activity in space. The Advanced Research Projects Agency (ARPA) was also created at this time to develop space technology for military application.[citation needed]

On July 29, 1958, Eisenhower signed the National Aeronautics and Space Act, establishing NASA. When it began operations on October 1, 1958, NASA absorbed the 46-year-old NACA intact; its 8,000 employees, an annual budget of US$100 million, three major research laboratories (LaRC, ARC, and LFPL) and two small test facilities.[16] A NASA seal was approved by President Eisenhower in 1959.[17] Elements of the ABMA and the NRL were incorporated into NASA. A significant contributor to NASA's entry into the Space Race with the Soviet Union was the technology from the German rocket program (led by Werner von Braun, who was now working for ABMA) which in turn incorporated the technology of American scientist Robert Goddard's earlier works.[18] Earlier research efforts within the U.S. Air Force[16] and many of ARPA's early space programs were also transferred to NASA.[19] In December 1958, NASA gained control of the JPL, a contractor facility operated by the Caltech.[16]

The most important part of NASA's activities are its missions; they can be divided into manned and unmanned. The latter can be either independent, carrying scientific equipment, or supportive, testing equipment for manned flights. In the beginning, NASA's missions focused on the spacerace with the Soviet Union, which won the first round, but later USA took the initiative and won the final race to the Moon. The unmanned missions have until now explored most of the solar system. They have also brought telescopes for deep space exploration into orbit around the Earth together with satellites for studying Earth itself.

Manned missionsThe rocket planes experiments started by NACA was taken a step further by NASA which used them as support for spaceflights, the first of which was one-manned and launched by military rockets. When the attention turned to reaching the Moon, the solution chosen was complicated but also the most economical. Supportive projects, both manned and unmanned were introduced and bigger rockets together with spacecraft and moonlander developed. The Moon landing and end of the space race meant a reduction of NASA's activities. Space stations of a more or less permanent nature, suggested already during the spacerace, were built and an international cooperation was introduced in an attempt to both bring nations together and at the same time share the high costs of space missio

The NACA XS-1 (Bell X-1) was followed by additional experimental vehicles, including the X-15 in cooperation with the US Air Force and US Navy. The design featured a slender fuselage with fairings along the side containing fuel and early computerized control systems.[21] When the spacerace began the main objective was to get a person into space as soon as possible, therefore the simplest spacecraft that could be launched by existing rockets was favored. This led to the choice of a small capsule spacecraft while rocket plane proposals like a modified X-15[22] were turned down.[23] Instead X-15 was used for development of techniques and equipment of value for the space missions. This included jets for changing the orientation of a spacecraft, space suits for astronauts and horizon definition for navigation.[24] Nearly 200 flights were made between 1959 and 1968 allowing NASA to collect data vital not only to the spacerace but also the design of the Space Shuttle.[21] The altitude record for X-15 was 354,200 feet (107.96 km).[24]

Project Mercury (1959-1963, manned missions from 1961)Main article: Project Mercury

ns. In all, more than 100 manned missions have been made by NASA since 1958.[20]

Project Mercury was initiated in 1958 and started NASA down the path of human space exploration with missions designed to discover if man could survive in space. Representatives from the U.S. Army, Navy, and Air Force were selected to provide assistance to NASA. Pilot selections were facilitated through coordination with U.S. defense research, contracting, and military test pilot programs. On May 5, 1961, astronaut Alan Shepard became the first American in space when he piloted Mercury-Redstone 3, called Freedom 7, on a 15-minute suborbital flight.[26] John Glenn became the first American to orbit the Earth on February 20, 1962 during the flight of Friendship 7.[27]

At that time the Soviet Union had taken the lead in the space race. In April 1961, one month before Alan Shepard, cosmonaut Yuri Gagarin became the first person in space when he orbited the Earth once in Vostok 1.[28] Further in August the same year, the follower Vostok 2 made a day long orbital flight[29] which led to canceling of additional American suborbital missions; they were no longer enough.[30] Three more orbital flights were made by the Mercury project after Friendship 7, the last in 1963.[31] Three additional orbital flights were cancelled since it was clear that the Mercury spacecraft had reached its limit of staying in space.[30]

The defeat in the first round of the spacerace led to the introduction of the Moon race program, Apollo, in 1961 just after the flight of Freedom 7. However, it was estimated that this could not be done in one step and that further projects in Earth orbit were needed.[32]

Project Gemini focused on conducting experiments and developing and practicing techniques required for lunar missions. The first Gemini flight with astronauts on board, Gemini 3, was flown by Gus Grissom and John Young on March 23, 1965.[33] Nine missions followed, showing that long-duration human space flight and rendezvous and docking with another vehicle in space were possible, and gathering medical data on the effects of weightlessness on humans.[34][35] Together with that, Gemini missions also included the first American spacewalks.

Even though the Gemini project managed to make a docking a year before the Soviet space program,[36] it was too early to call it a victory. The maneuvers practiced by Gemini could be used in two ways: a spacecraft could dock with a rocket stage in orbit around the Earth and use it for going to the Moon or a spacecraft together with a Moon lander could be sent to the Moon by a single rocket and then separate and dock again after the lander had been down on the surface. However, there was a third and more direct way of going to the Moon; the Soviet Union could just build a big rocket and land the top of it on the Moon. That again could take itself back to Earth without using rendezvous or docking. In that case the Gemini project would have been a waste of time.[37]

The Apollo (Moon) program was one of the most expensive American scientific programs ever. It is estimated to have cost $202 billion in present day US$.[38][39] In comparison the Manhattan (atom bomb) project cost roughly today-US$25.8 billion.[38][40] It used the Saturn rockets as launch vehicles, which were far bigger than the rockets build for previous projects.[41] The spacecraft was also bigger as can be seen on the picture; it had two main parts: the combined command and service module (CSM) and the lunar landing module (LM). The LM was to be left on the Moon and only the command module (CM) containing the astronauts would eventually return to Earth. (For details see: Apollo 11 flight gallery)
