The Use of satellites
After 1958, America launched many satellites for different usage such as reconnaissance satellite, meteorological satellite. All these satellites have influenced our daily life very much. Through them we can make our life more safe and wonderful.

NASA's space shuttle fleet began setting records with its first launch on April 12, 1981 and continued to set high marks of achievement and endurance through 30 years of missions. Starting with Columbia and continuing with Challenger, Discovery, Atlantis and Endeavour, the spacecraft has carried people into orbit repeatedly, launched, recovered and repaired satellites, conducted cutting-edge research and built the largest structure in space, the International Space Station. The final space shuttle mission, STS-135, ended July 21, 2011 when Atlantis rolled to a stop at its home port, NASA's Kennedy Space Center in Florida.
The Use of satellites
From my perspective, the most influential achievement of the US satellites is GPS. Although it was planned to serve the US military at the beginning ; It play an more important role in rescue and travel guide. If you drive your car to a new place it will help much.

Project Apollo
Forty years ago, men from Earth began for the first time to leave our home planet and journey to the moon.
Manned Space Flight
Project mercury was the first human spaceflight program of the United States. It ran from 1959 through 1963 with the goal of putting a human in orbit around the Earth. The Mercury-Atlas 6 flight on February 20, 1962, was the first mercury flight to achieve this goal.
Deep Space Exploration
Eight years of hard work by thousands of Americans came to fruition on July 20, 1969, when Apollo 11 commander Neil Armstrong stepped out of the lunar module and took "one small step" in the Sea of Tranquility, calling it "a giant leap for mankind."
Manned Space Flight
Skylab program objectives were twofold: To prove that humans could live and work in space for extended periods, and to expand our knowledge of solar astronomy well beyond Earth-based observations. The program was successful in all respects despite early mechanical difficulties. Skylab was launched into Earth orbit by a Saturn V rocket on May 14, 1973. Through the use of a "dry" third stage of the Saturn V rocket, the station was completely outfitted as a workshop area before launch.
Deep Space Exploration
Six of the missions -- Apollos 11, 12, 14, 15, 16 and 17 -- went on to land on the moon, studying soil mechanics, meteoroids, seismic, heat flow, lunar ranging, magnetic fields and solar wind. Apollos 7 and 9 tested spacecraft in Earth orbit; Apollo 10 orbited the moon as the dress rehearsal for the first landing. An oxygen tank explosion forced Apollo 13 to scrub its landing, but the "can-do" problem solving of the crew and mission control turned the mission into a "successful failure."

From landing until the final data transmission on September 27, 1997, Mars Pathfinder returned 2.3 billion bits of information, including more than 16,500 images from the lander and 550 images from the rover, as well as more than 15 chemical analyses of rocks and soil and extensive data on winds and other weather factors. Findings from the investigations carried out by scientific instruments on both the lander and the rover suggest that Mars was at one time in its past warm and wet, with water existing in its liquid state and a thicker atmosphere.

Mars Pathfinder
Mars Pathfinder was designed to be a demonstration of the technology necessary to deliver a lander and a freeranging robotic rover to the surface of Mars in a costeffective and efficient manner. Pathfinder not only accomplished this goal but also returned an unprecedented amount of data and outlived its primary design life.

The Use of satellites
On Jan 31st, 1958 the US launched its first satellite explore into the space, which became the beginning of the space exploration of America. On Aug 19th, 1964 America launched a satellite which have the same speed with earth rotation as a communication satellite.
Deep Space Exploration
From 1968 to 1972, NASA's Apollo astronauts tested out new spacecraft and journeyed to uncharted destinations. It all started on May 25, 1961, when President John F. Kennedy announced the goal of sending astronauts to the moon before the end of the decade. Coming just three weeks after Mercury astronaut Alan Shepard became the first American in space, Kennedy's bold challenge set the nation on a journey unlike any before in human history.
