Spaceflight is the movement of spacecraft into and through outer space, primarily using rocket technology for propulsion. Spaceflight is used in space exploration, the endeavour to reach, explore, and exploit the space outside the Earth's atmosphere, and also in commercial activities like space tourism and satellite telecommunications. It is generally based on the use of rockets to transport machines, animals, and humans to, and subsequently through, space. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other earth observation satellites. Objects launched into space may follow a sub-orbital trajectory and return to Earth immediately, stay in orbit around Earth, travel in the space between the planets, or aim to leave the space dominated by the Sun completely.
Salyut 6 (Russian: Салют-6; lit. Salute 6) was a Soviet orbital space station, the eighth flown as part of the Salyut programme. Launched on 29 September 1977 by a Proton rocket, the station was the first of the 'second-generation' type of space station. Salyut 6 possessed several revolutionary advances over the earlier Soviet space stations, which it nevertheless resembled in overall design. These included the addition of a second docking port, a new main propulsion system and the station's primary scientific instrument, the BST-1M multispectral telescope. The addition of the second docking port made crew handovers and station resupply by unmanned Progress freighters possible for the first time, which in turn allowed the programme to evolve from short-duration station visits to long-duration expeditions, marking the beginning of the transition to multi-modular, long-term research stations in space.
From 1977 until 1982, Salyut 6 was visited by five long- and eleven short-duration crews, including cosmonauts from Warsaw Pact countries as part of the Intercosmos programme. The very first long-duration crew to visit the station broke a long-standing endurance record set on board the American Skylab station, staying 96 days in orbit; the longest expedition lasted 185 days. These crews were responsible for carrying out the primary missions of Salyut 6, including astronomy, Earth-resources observations and the study of human adaptation to space. Following the completion of these missions and the launch of its successor, Salyut 6 was deorbited on 29 July 1982, almost five years after its launch.
Neil Alden Armstrong (August 5, 1930–25 August, 2012) was an American astronaut, test pilot, university professor, and United States Naval Aviator. He is the first person to set foot on the Moon. After serving as a naval aviator from 1949 to 1952 in the Korean War, Armstrong joined the National Advisory Committee for Aeronautics (NACA) in 1955. Over the next 17 years, he was an engineer, test pilot, astronaut and administrator for NACA and its successor agency, the National Aeronautics and Space Administration (NASA). As a research pilot, Armstrong served as project pilot on the F-100 Super Sabre A and C aircraft, F-101 Voodoo, and the Lockheed F-104A Starfighter. His first spaceflight was aboard Gemini 8 in 1966, for which he was the command pilot. On this mission, he performed the first manned docking of two spacecraft together with pilot David Scott. Armstrong's second and last spaceflight was as mission commander of the Apollo 11 moon landing mission on July 20, 1969. On this mission, Armstrong and Buzz Aldrin descended to the lunar surface and spent 2½ hours exploring making him the first human to walk on the Moon, while Michael Collins remained in orbit in the Command Module. Armstrong is a recipient of the Congressional Space Medal of Honor.
…that the South Korean launch system Naro-1, which made its first flight on 25 August 2009, is based on the Russian Angara (pictured)?
