Space Technology in Modern World

Space science is the study of everything above and beyond the surface of the Earth, from Earth's atmosphere to the very edges of the universe. Space Technology refers to the technology in satellites and ground systems used by space scientists to study the universe (looking up) and the earth (looking down), or to deliver services to users on the ground. The vast majority of satellites are launched into space to provide services to people on Earth.

Satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. Space is the property of the universe, in which matter is physically extended and objects have positions relative to one another.

In classical mechanics, space was treated as being separate from time and is thought of as one of the few fundamental physical quantities. In Isaac Newton's view space was absolute, and held that it exists permanently and independently of whether there is any matter in the space or moving through it.

Space exploration is the use of astronomy and space technology to explore outer space. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft. Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War.

The first human spaceflight was Vostok 1 (East 1), carrying 27 year old cosmonaut Yuri Gagarin on April 12, 1961. The spacecraft completed one orbit around the globe, lasting about 1 hour and 48 minutes. Gagarin's flight resonated around the world; it was a demonstration of the advanced Soviet space program and it opened an entirely new era in space exploration — human spaceflight.

Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the three currently operational orbiters in the Space Shuttle fleet of NASA, the space agency of the United States. (The other two are Atlantis and Endeavour.) When first flown in 1984, Discovery became the third operational orbiter, and is now the oldest orbiter in service. Discovery has performed both research and International Space Station (ISS) assembly missions.

Space technology is technology that is related to entering space, maintaining and using systems during spaceflight and returning people and things from space.

Space technology has a huge impact on the everyday lives of people; and something as simple as checking the weather or watching satellite television or receiving a parcel guided by satellite, it touches most people's lives on any given day.
