supports: Aeronautics (from the ancient Greek words  "r", which means "air", and  "nautik" which means "navigation", i.e. "navigation into the air") is the science or art involved with the study, design, and manufacturing of air flight capable machines, and the techniques of operating aircraft and rockets within the atmosphere. The British Royal Aeronautical Society identifies the aspects of "aeronautical Art, Science and Engineering" and "the profession of Aeronautics (which expression includes Astronautics)."  The Saturn IB (pronounced "one B", also known as the Uprated Saturn I) was an American launch vehicle commissioned by the National Aeronautics and Space Administration (NASA) for the Apollo program. It replaced the S-IV second stage of the Saturn I with the much more powerful S-IVB, able to launch a partially fueled Apollo Command/Service Module (CSM) or a fully fueled Lunar Module (LM) into low Earth orbit for early flight tests before the larger Saturn V needed for lunar flight was ready. A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting crewmembers, which is designed to remain in space (most commonly as an artificial satellite in low Earth orbit) for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. three space stations are in orbit: the International Space Station, which is permanently manned, China's Tiangong-1 (defunct) and Tiangong-2 (launched 15 September 2016, not permanently manned). Previous stations include the Almaz and Salyut series, Skylab, and most recently "Mir". Skylab was the United States' first space station, orbiting Earth from 1973 to 1979, when it fell back to Earth amid huge worldwide media attention. Launched and operated by NASA, Skylab included a workshop, a solar observatory, and other systems necessary for crew survival and scientific experiments. It was launched unmanned by a modified Saturn V rocket, with a weight of . Lifting Skylab into low earth orbit was the final mission and launch of a Saturn V rocket (which was famous for carrying the manned Moon landing missions). Skylab was not simply a place of habitation; it was a place of massive science experiments for which when the bulk of data was returned, such as on films that had to be physically returned to Earth began the process of analyzing scientific and engineering data as each mission was completed. Skylab's solar observatory was one major aspect of study, and solar science was significantly advanced by the telescope; it observed the Sun as it never before. As Skylab finished up NASA's focus had shifted to development of the Space Shuttle, which had the promise of reducing the cost of space access compared to the previous launch systems Joseph Peter Kerwin , M.D. ( born February 19 , 1932 ) , ( Capt , USN , Ret . ) , is an American physician and former NASA astronaut , who served as Science Pilot for the Skylab 2 mission from May 25 -- June 22 , 1973 . He was the first physician to be selected for astronaut training . Health is the level of functional and metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes. The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete". Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction. Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. A patient is any recipient of health care services. The patient is most often ill or injured and in need of treatment by a advanced practice registered nurse, physiotherapist, physician, physician assistant, psychologist, podiatrist, veterinarian, or other health care provider. An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists. Skylab 2 (also SL-2 and SLM-1) was the first manned mission to Skylab, the first U.S. orbital space station. The mission was launched on a Saturn IB rocket and carried a three-person crew to the station. The name Skylab 2 also refers to the vehicle used for that mission. The Skylab 2 mission established a twenty-eight-day record for human spaceflight duration. Furthermore, its crew were the first space station occupants ever to return safely to Earth  the only previous space station occupants, the crew of the 1971 Soyuz 11 mission that had manned the Salyut 1 station for twenty-four days, were killed during reentry. A spacecraft is a vehicle, or machine designed to fly in outer space. Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. The National Aeronautics and Space Administration (NASA ) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program as well as aeronautics and aerospace research. A physician, medical practitioner, medical doctor or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients and methods of treatmentknown as specialitiesor they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communitiesknown as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatmentthe "science" of medicineand also a decent competence in its applied practicethe art or "craft" of medicine.
