Deep space exploration is the branch of astronomy, astronautics and space technology involved in the exploration of distant regions of outer space. The physical exploration of space is carried out both by manned space flights (deep space astronautics) and by robotic spaceships. It satisfies the human desire to explore and travel and, in the coming years and decades, could even provide our species with new places to call home, something especially relevant now that the Earth is increasingly populated. Space exploration is the continuous discovery and exploration of heavenly structures in outer space using space technology in continuous evolution and growth.
During the 1960s, NASA made progress towards President Kennedy's goal of taking a human to the Moon with a program called Project Gemini, in which astronauts tested the technology needed for future flights to the Moon and tested their own ability to withstand many days in space flights. Common reasons for exploring space include the advancement of scientific research, the union of different nations, the guarantee of the future survival of humanity and the development of military and strategic advantages over other countries. The first human-made object to go into space was a German V2 missile, launched on a test flight in 1942.Other countries also considered that having a successful space program was an important indicator of national strength. This reality meant that space exploration had to serve very broad interests and, in fact, it has done so in a variety of ways.
Eisenhower had decided not to compete for prestige with the Soviet Union in a space race, and his successor, John F. Governments realized early on that the ability to observe the Earth from space could provide significant benefits to the general public, apart from military and security uses. All these activities of discovery, scientific understanding and application of that understanding in the service of human purposes are elements of space exploration. It may also explain why space exploration has been a common and enduring theme in literature and art.
While the only trips humans have made from the vicinity of the Earth, Apollo flights to the Moon, were motivated by Cold War competition, humans have repeatedly been asked to return to the Moon, travel to Mars, and visit other places in the solar system and beyond. After the first 20 years of exploration, the focus shifted from one-time flights to renewable equipment, such as the space shuttle program, and from competition to cooperation, as was the case with the International Space Station (ISS). However, even the very development of space travel technology can lead to unwanted but beneficial “derivative” technologies with some very practical applications. Some examples of these efforts are the development of the Curiosity Mars rover, the Cassini-Huygens mission to Saturn and its moons, and the development of important space-based astronomical observatories, such as the Hubble Space Telescope.
Then there is the growing cloud of space debris to deal with in Earth orbit (extinct satellites, discarded rockets and other debris) that move just as quickly.
