Apollo Spacecraft Feasibility Study
The Apollo spacecraft feasibility study was conducted by NASA from July 1960 through May 1961 to investigate preliminary designs for a post- Project Mercury multi-crewed spacecraft to be used for possible space station, circum-lunar, lunar orbital, or crewed lunar landing missions. Six-month, $250,000 study contracts were awarded to General Dynamics/Convair, General Electric, and the Glenn L. Martin Company. Meanwhile, NASA conducted its own inhouse design study led by Maxime Faget, intended as a gauge of the competitors' entries. The three companies spent varying amounts of their own money in excess of the $250,000 to produce designs which included a ''re-entry module'' separate from the ''mission module'' cabin, and a ''propulsion and equipment module''. One week after the presentation of the contractors' designs, President John F. Kennedy committed NASA to a crewed lunar landing, giving the Apollo program an immediate, critical focus. NASA decided to discard the study design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soyuz 7K-OK
Soyuz 7K-OK was the first generation of Soyuz (spacecraft), Soyuz spacecraft and was flown between 1967 and 1971. The 7K-OK was used for the first ferry flights to the Salyut programme, Salyut space station program, beginning a long history of space station service that continues today with the International Space Station (ISS). , the 7K-OK is notable for the only fatalities of the Soyuz programme, with Soyuz 1 in 1967 (sole crew-member killed by parachute failure) and Soyuz 11 in 1971 (three crew killed by depressurisation during reentry). The first uncrewed automated docking in the history of spaceflight was achieved between 7K-OK spacecraft Kosmos 186 and Kosmos 188 in 1967. Additionally firsts include the first docking between two crewed spacecraft (Soyuz 4 and Soyuz 5), the longest crewed flight involving only one spacecraft (the 18-day flight of Soyuz 9 in 1970), and the first successful transfer of crew to the first space station in the history of space flight (Soyuz ...

Artificial Gravity
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from gravity. In a more general sense, "artificial gravity" may also refer to the effect of linear acceleration, e.g. by means of a rocket engine. Rotational simulated gravity has been used in simulations to help astronauts train for extreme conditions. Rotational simulated gravity has been proposed as a solution in human spaceflight to the adverse health effects caused by prolonged weightlessness. However, there are no current practical outer space applications of artificial gravity for humans due to concerns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Docking And Berthing Of Spacecraft
Docking and berthing of spacecraft is the joining of two space vehicles. This connection can be temporary, or partially permanent such as for space station modules. ''Docking'' specifically refers to joining of two separate free-flying space vehicles. ''Berthing'' refers to mating operations where a passive module/vehicle is placed into the mating interface of another space vehicle by using a robotic arm. Because the modern process of un-berthing requires more crew labor and is time-consuming, berthing operations are unsuited for rapid crew evacuations in the event of an emergency. History Docking Spacecraft docking capability depends on space rendezvous, the ability of two spacecraft to find each other and station-keep in the same orbit. This was first developed by the United States for Project Gemini. It was planned for the crew of Gemini 6 to rendezvous and manually dock under the command of Wally Schirra, with an uncrewed Agena Target Vehicle in October 1965, but ...

Space Rendezvous
A space rendezvous () is a set of orbital maneuvers during which two spacecraft, one of which is often a space station, arrive at the same orbit and approach to a very close distance (e.g. within visual contact). Rendezvous requires a precise match of the orbital velocities and position vectors of the two spacecraft, allowing them to remain at a constant distance through orbital station-keeping. Rendezvous may or may not be followed by docking or berthing, procedures which bring the spacecraft into physical contact and create a link between them. The same rendezvous technique can be used for spacecraft "landing" on natural objects with a weak gravitational field, e.g. landing on one of the Martian moons would require the same matching of orbital velocities, followed by a "descent" that shares some similarities with docking. History In its first human spaceflight program Vostok, the Soviet Union launched pairs of spacecraft from the same launch pad, one or two days apart ( V ...

Launch Escape System
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule that can be used to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is still on the launch pad, or during its ascent. Such systems are usually of two types: *A solid-fueled rocket, mounted above the capsule on a tower, which delivers a relatively large thrust for a brief period of time to send the capsule a safe distance away from the launch vehicle, at which point the capsule's parachute recovery system can be used for a safe landing on ground or water. The tower and rocket are jettisoned from the space vehicle in a normal flight at the point where it is either no longer needed, or cannot be e ...

Ames Research Center
The Ames Research Center (ARC), also known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley. It was founded in 1939 as the second National Advisory Committee for Aeronautics (NACA) laboratory. That agency was dissolved and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA) on October 1, 1958. NASA Ames is named in honor of Joseph Sweetman Ames, a physicist and one of the founding members of NACA. At last estimate NASA Ames had over US$3 billion in capital equipment, 2,300 research personnel and a US$860 million annual budget. Ames was founded to conduct wind-tunnel research on the aerodynamics of propeller-driven aircraft; however, its role has expanded to encompass spaceflight and information technology. Ames plays a role in many NASA missions. It provides leadership in astrobiology; small satellites; robotic lunar exploration; the search for habitable planets; s ...
