Orbiting Astronomical Observatory
The Orbiting Astronomical Observatory (OAO) satellites were a series of four American space observatories launched by NASA between 1966 and 1972, managed by NASA Chief of Astronomy Nancy Grace Roman. These observatories, including the first successful space telescope, provided the first high-quality observations of many objects in ultraviolet light. Although two OAO missions were failures, the success of the other two increased awareness within the astronomical community of the benefits of space-based observations, and led to the instigation of the Hubble Space Telescope. OAO-1 The first Orbiting Astronomical Observatory was launched successfully on 8 April 1966, carrying instruments to detect ultraviolet, X-ray and gamma ray emission. Before the instruments could be activated, a power failure resulted in the termination of the mission after three days. The spacecraft was out of control, so that the solar panels could not be deployed to recharge the batteries that would s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apollo Program
The Apollo program, also known as Project Apollo, was the United States human spaceflight program led by NASA, which Moon landing, landed the first humans on the Moon in 1969. Apollo followed Project Mercury that put the first Americans in space. It was conceived in 1960 as a three-person spacecraft during President Presidency of Dwight D. Eisenhower, Dwight D. Eisenhower's administration. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to United States Congress, Congress on May 25, 1961. It was the third American human spaceflight program to fly, preceded by Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo. Kennedy's goal was accomplished on the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module (LM) on July 20, 1969, and walked on the lunar surface, while Michael Collins ( ...

Launch Complex 36
Launch Complex 36 (LC-36) is a launch complex located at the Cape Canaveral Space Force Station in Florida. Located south of the Missile Row launch range, the complex originally consisted of two pads—designated LC-36A and LC-36B—to support the flights of Atlas (rocket family), Atlas launch vehicles equipped with a Centaur (rocket stage), Centaur upper stage. From the 1960s to the 1980s, LC-36 was used by NASA and the United States Air Force to launch many payloads from the Atlas-Centaur and its derivatives, including the Pioneer program, Pioneer, Surveyor program, Surveyor, and Mariner program, Mariner probes. Throughout the 1990s and early 2000s, General Dynamics (and later Lockheed Martin) modified the two pads to support the larger Atlas I, Atlas II, and Atlas III. Following the Atlas program's relocation to Cape Canaveral Space Launch Complex 41, Space Launch Complex 41 (SLC-41) in 2005, LC-36 stood vacant until Blue Origin acquired the lease in 2015 for use by their heavy ...

Atlas SLV-3
The Atlas SLV-3, or SLV-3 Atlas was an American expendable launch system derived from the SM-65 Atlas / SM-65D Atlas missile. It was a member of the Atlas family of rockets. The Atlas SLV-3 was a stage and a half rocket, built as a standardized replacement for earlier Atlas launch systems, which had been derived from the various Atlas missiles. Most space launcher variants of the Atlas up to 1965 were derived from the D-series Atlas ICBM with custom modifications for the needs of the particular mission. The SLV-3 would use a standardized configuration based on the Atlas D missile for all launches with the exception of different widths for the top of the rocket depending on the upper stage being flown. The SLV-3 had thicker gauge tank walls to support the weight of upper stages as well as upgraded engines and removal of unneeded ICBM hardware such as retrorockets. Although the main engines had greater thrust, the verniers were detuned slightly in the interest of improved ISP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canaveral Air Force Station
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida. Headquartered at the nearby Patrick Space Force Base, the station is the primary launch site for the Space Force's Eastern RangeCAST 1999, p. 1-12. with four launch pads currently active (Space Launch Complexes 36, 40, 41 and 46). The facility is south-southeast of NASA's Kennedy Space Center on adjacent Merritt Island, with the two linked by bridges and causeways. The Cape Canaveral Space Force Station Skid Strip provides a runway close to the launch complexes for military airlift aircraft delivering heavy and outsized payloads to the Cape. A number of American space exploration pioneers were launched from CCSFS, including the first U.S. Earth satellite (1958), first U.S. astronaut (1961), first U.S. astronaut in orbit (1962), first two-man U.S. spacecraft (1965), first U.S. uncrewed lu ...

Launch Complex 12
Launch Complex 12 (LC-12) at Cape Canaveral Space Force Station, Florida was a launch pad used by Atlas rockets and missiles between 1958 and 1967. It was the second-most southern of the pads known as Missile Row, between LC-11 to the south and LC-13 to the north. Along with Complexes 11, 13 and 14, LC-12 featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was tall and a reinforced blockhouse. The rockets were delivered to the launch pad by means of a ramp on the southwest side of the launch pedestal. Currently, LC-12 is leased by Blue Origin, and has been used by them as a storage site. History Atlas operations Atlas A, C and D missiles were tested from the site. It was also used for orbital launches of Atlas-Able and later Atlas-Agena rockets, and two Project FIRE suborbital tests for Project Apollo, using Atlas D rockets. ...

Atlas-Agena
The Atlas-Agena was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas (rocket family), Atlas family of rockets, and was launched 109 times between 1960 and 1978. It was used to launch the first five Mariner program, Mariner uncrewed probes to the planets Venus and Mars, and the Ranger program, Ranger and Lunar Orbiter program, Lunar Orbiter uncrewed probes to the Moon. The upper stage was also used as an uncrewed orbital Agena target vehicle, target vehicle for the Project Gemini, Gemini crewed spacecraft to practice space rendezvous, rendezvous and docking and berthing of spacecraft, docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified DoD payloads. The Atlas-Agena was a two-and-a-half-stage rocket, with a SM-65 Atlas#'Stage-and-a-half', stage-and-a-half Atlas missile as the first stage, and an RM-81 Agena second stage. Initially, SM-65D Atlas, Atlas D m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second
The second (symbol: s) is a unit of time derived from the division of the day first into 24 hours, then to 60 minutes, and finally to 60 seconds each (24 × 60 × 60 = 86400). The current and formal definition in the International System of Units (SI) is more precise: The second ..is defined by taking the fixed numerical value of the caesium frequency, Δ''ν''Cs, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This current definition was adopted in 1967 when it became feasible to define the second based on fundamental properties of nature with caesium clocks. As the speed of Earth's rotation varies and is slowing ever so slightly, a leap second is added at irregular intervals to civil time to keep clocks in sync with Earth's rotation. The definition that is based on of a rotation of the earth is still used by the Universal Time 1 (UT1) system. Etymology "Minute" ...

X Persei
X Persei is a high-mass X-ray binary system located in the constellation Perseus (constellation), Perseus, approximately 950 parsecs away. It is catalogued as 4U 0352+309 in the final Uhuru (satellite), Uhuru catalog of X-ray objects. The conventional star component of X Persei has been classified either as an O-type giant or a B-type main sequence star. It is a Be star, rotating rapidly, and at times surrounded by a disk of expelled material. This qualifies it as a Gamma Cassiopeiae variable, and the visual range is magnitude 6 - 7. In 1989 and 1990, the spectrum of X Persei changed from a Be star to a normal B class star while it faded significantly. This appears to have been caused by the loss of the excretion disk. The disk has since reformed and shows strong emission lines. The system also contains a neutron star which is a pulsar with an unusually long period of 837 seconds. The pulsar has shown period changes that are associated with mass transfer from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
