Falcon 9 Flight 19
SpaceX CRS-7, also known as SpX-7, was a private American Commercial Resupply Service mission to the International Space Station, contracted to NASA, which launched and failed on June 28, 2015. It disintegrated 139 seconds into the flight after launch from Cape Canaveral, just before the first stage was to separate from the second stage. It was the ninth flight for SpaceX's uncrewed Dragon cargo spacecraft and the seventh SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. The vehicle launched on a Falcon 9 v1.1 launch vehicle. It was the nineteenth overall flight for the Falcon 9 and the fourteenth flight for the substantially upgraded Falcon 9 v1.1. Launch history In January 2015, the launch was tentatively scheduled by NASA for no earlier than June 13, 2015. This was adjusted to June 22, 2015, then moved forward to June 19, 2015, and adjusted again to June 26, 2015. Subsequently, the launch had been rescheduled to June 28, 2015, ...

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon 9 Ocean Booster Landing Tests
The Falcon 9 first-stage landing tests were a series of controlled-descent flight tests conducted by SpaceX between 2013 and 2016. Since 2017, the first stage of Falcon 9 missions has been routinely landed if the rocket performance allowed it, and if SpaceX chose to recover the stage. The program's objective was to reliably execute controlled re-entry, descent and landing ( EDL) of the Falcon 9 first stage into Earth's atmosphere after the stage completes the boost phase of an orbital spaceflight. The first tests aimed to touch down vertically in the ocean at zero velocity. Later tests attempted to land the rocket precisely on an autonomous spaceport drone ship (a barge commissioned by SpaceX to provide a stable landing surface at sea) or at Landing Zone 1 (LZ-1), a concrete pad at Cape Canaveral. The first ground landing at LZ-1 succeeded in December 2015, and the first landing at sea on a drone ship in April 2016. The second landed booster, B1021, was the first to fly again in ...

NASA Docking System
The NASA Docking System (NDS) is a Docking and berthing of spacecraft, spacecraft docking and berthing mechanism used on the International Space Station (ISS), the Orion spacecraft, and the Boeing Starliner, Starliner. The NDS is NASA's implementation of the International Docking System Standard (IDSS), an international spacecraft docking standard promulgated by the International Space Station Multilateral Coordination Board. The international Low Impact Docking System (iLIDS) is the precursor to the NDS. NDS Block 1 was designed and built by The Boeing Company in Houston, TX, to meet the IDSS standards. Design qualification testing took place through January 2017. Using NDS, NASA developed the International Docking Adapter (IDA) to provide two IDSS-compliant docking ports on the ISS. The IDAs were delivered to the ISS starting in 2016. Each of two existing Pressurized Mating Adapters has an IDA permanently attached, so the former PMA function is no longer available for visiting s ...

Androgynous Peripheral Attach System
The terms Androgynous Peripheral Attach System (APAS), Androgynous Peripheral Assembly System (APAS) and Androgynous Peripheral Docking System (APDS), are used interchangeably to describe a family of spacecraft docking mechanisms, and are also sometimes used as a generic name for any docking system in that family. A system similar to APAS-89/95 is used by the Chinese Shenzhou spacecraft. Overview The name of the system is Russian in origin, and is an acronym, , in the Cyrillic alphabet, from the Russian (''Androginno-periferiynyy agregat stykovki''). The English acronym was designed to be just the same letters but in the Latin alphabet, for which the first two words are direct counterparts of those in the original. The third word in Russian comes from the German , meaning "complicated mechanism", and the last means "docking". The last two words in the English name were picked to begin with the same equivalent letters as in the Russian name. The idea behind the design is that unli ...

Pressurized Mating Adapter
The Pressurized Mating Adapter (PMA) is a class of spacecraft adapters that convert the Common Berthing Mechanism (CBM) used on the US Orbital Segment to APAS-95 docking ports. There are three PMAs located on the International Space Station (ISS); the first two were launched with the ''Unity'' connecting module in 1998 aboard STS-88, and the third was launched in 2000 aboard STS-92. All three of the PMAs are now used to permanently connect parts of the ISS, so they are no longer available as docking ports for visiting spacecraft. Design/History Its origins lie in designs for the Pressurized Docking Mast, consisting of an off-axis frustoconical docking tunnel contained within a framework and a retractable coupling mechanism, later part of the Pressurized Berthing Adapter assembly that appeared in designs for Space Station Freedom 1987, and the reduced design referred to as 'Fred' 1991. After 1992-93 and the Russian integration into the International Space Station Alpha pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Docking Adapter
The International Docking Adapter (IDA) is a spacecraft docking system adapter developed to convert APAS-95 to the NASA Docking System (NDS). An IDA is placed on each of the International Space Station's (ISS) two open Pressurized Mating Adapters (PMAs), both of which are connected to the ''Harmony'' module. History Prior to IDA there were several different iterations of docking adapters that were meant to fill a similar role but were ultimately canceled. APAS to LIDS Adaptor System The APAS to LIDS Adaptor System (ATLAS) was announced in 2008. It would have been placed on the open PMAs and converted APAS-95 to the Low Impact Docking System (LIDS). ATLAS was planned to be launched on Orion's first two missions to the International Space Station. Orion's missions to the ISS were later canceled altogether and its role as a crew transporter was replaced by the Commercial Crew Program. Common Docking Adapter The Common Docking Adapter (CDA) was announced in 2009. It was planne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Capsule
A space capsule is an often-crewed spacecraft that uses a blunt-body reentry capsule to reenter the Earth's atmosphere without wings. Capsules are distinguished from other satellites primarily by the ability to survive reentry and return a payload to the Earth's surface from orbit. Capsule-based crewed spacecraft such as Soyuz or Orion are often supported by a service or adapter module, and sometimes augmented with an extra module for extended space operations. Capsules make up the majority of crewed spacecraft designs, although one crewed spaceplane, the Space Shuttle, has flown in orbit. Current examples of crewed space capsules include Soyuz, Shenzhou, and Dragon 2. Examples of new crew capsules currently in development include NASA's Orion, Boeing's Starliner, Russia's Orel, India's Gaganyaan, and China's next-generation crewed spacecraft. Historic examples of crewed capsules include Vostok, Mercury, Voskhod, Gemini, and Apollo, and active programs include the New She ...

Orbital Elements
Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same orbit, but certain schemes, each consisting of a set of six parameters, are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational perturbations by other objects and the effects of general relativity. A Kepler orbit is an idealized, mathematical approximation of the orbit at a particular time. Keplerian elements The traditional orbital elements are the six Keplerian elements, after Johannes Kepler and his laws of planetary motion. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its focus at the common center of mass. When viewed from a non-inertial frame centered on one of the bodies, only the traj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strut
A strut is a structural component commonly found in engineering, aeronautics, architecture and anatomy. Struts generally work by resisting longitudinal compression, but they may also serve in tension. Human anatomy Part of the functionality of the clavicle is to serve as a strut between the scapula and sternum, resisting forces that would otherwise bring the upper limb close to the thorax. Keeping the upper limb away from the thorax is vital for its range of motion. Complete lack of clavicles may be seen in cleidocranial dysostosis, and the abnormal proximity of the shoulders to the median plane exemplifies the clavicle's importance as a strut. Architecture and construction Strut is a common name in timber framing for a support or brace of scantlings lighter than a post. Frequently struts are found in roof framing from either a tie beam or a king post to a principal rafter. Struts may be vertically plumb or leaning (then called canted, raking, or angled) and may be straight ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orlando Sentinel
The ''Orlando Sentinel'' is the primary newspaper of Orlando, Florida, and the Central Florida region. It was founded in 1876 and is currently owned by Tribune Publishing Company. The ''Orlando Sentinel'' is owned by parent company, '' Tribune Publishing''. This company was acquired by Alden Global Capital, which operates its media properties through Digital First Media, in May 2021. The newspaper's website utilizes geo-blocking, thus making it unaccessible from European countries. History The ''Sentinel''s predecessors date to 1876, when the ''Orange County Reporter'' was first published. The ''Reporter'' became a daily newspaper in 1905, and merged with the ''Orlando Evening Star'' in 1906. Another Orlando paper, the ''South Florida Sentinel'', started publishing as a morning daily in 1913. Then known as the ''Morning Sentinel'', it bought the ''Reporter-Star'' in 1931, when Martin Andersen came to Orlando to manage both papers. Andersen eventually bought both papers outrigh ...
