SpaceX CRS-7
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, at ...

Commercial Resupply Services
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first phase of CRS contracts (CRS-1) were signed in 2008 and awarded $1.6 billion to SpaceX for twelve SpaceX Dragon 1, Dragon 1 and $1.9 billion to Orbital Sciences for eight Cygnus (spacecraft), Cygnus flights, covering deliveries to 2016. The first operational resupply missions were flown by SpaceX in 2012 (SpaceX CRS-1, CRS SpX-1) and Orbital in 2014 (Cygnus CRS Orb-1, CRS Orb-1). In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK. A second phase of contracts (CRS-2) was solicited in 2014. CRS-2 contracts were awarded in January 2016 to Orbital ATK's continued use of Cygnus (spacecraft), Cygnus, Sierra Nevada Corporation's new Dream Chaser, and SpaceX's new SpaceX Dragon 2, Dragon 2, for cargo transport flights beginning in 2019 and expec ...

The Falcon 9 has been noted for its reliability and high launch cadence, with successful launches, two in-flight failures, one partial failure and one pre-flight destruction. It is the most-launched American orbital rocket in history. The rocket has two-stage-to-orbit, two stages. The first (booster) stage carries the second stage and payload to a predetermined speed and altitude, after which the second stage accelerates the payload to its target orbit. The Booster (rocketry), booster is capable of Vertical takeoff, vertical landing, landing vertically to fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressurized Mating Adapter
A Pressurized Mating Adapter (PMA) is a component used on the International Space Station (ISS) to convert the Common Berthing Mechanism (CBM) interface used to connect ISS modules to an APAS-95 spacecraft docking port. Three PMAs are attached to the US Orbital Segment of ISS. PMA-1 and PMA-2 were launched along with the ''Unity'' module in 1998 aboard STS-88; PMA-3 was launched in 2000 aboard STS-92. PMA-1 permanently connects the ''Unity'' and '' Zarya'' modules. International Docking Adapters were permanently installed on PMA-2 and PMA-3 in 2017 to convert them from the APAS-95 standard to the newer International Docking System Standard (IDSS). Design and 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 d ...

International Docking Adapter
The International Docking Adapter (IDA) is a spacecraft docking system adapter developed to convert APAS-95 to support docking with spacecraft that implement the International Docking System Standard. The IDA uses NASA Docking System (NDS) hardware. An IDA was permanently installed 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 several different docking adapters were designed to fill a similar role but were never implemented. 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 ...

Space Capsule
A space capsule is a spacecraft designed to transport cargo, scientific experiments, and/or astronauts to and from space. Capsules are distinguished from other spacecraft by the ability to survive reentry and return a payload to the Earth's surface from orbit or sub-orbit, and are distinguished from other types of recoverable spacecraft by their blunt shape, not having wings and often containing little fuel other than what is necessary for a safe return. Capsule-based human spaceflight, crewed spacecraft such as Soyuz (spacecraft), Soyuz or Orion (spacecraft), 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 spacecraft, Soyuz, Shenzhou spacecraft, Shenzhou, and SpaceX Dragon 2, Dragon 2. Examples of new crew capsu ...

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 are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational Perturbation (astronomy), 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. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its Focus (geometry), focus at the common center of mass. When viewed from a non-inertial frame centered on one of the bodies, only the trajectory of the opposite body is apparent; Keplerian elements describe these non-inertial trajectories. An orbit has two sets of Keplerian elements depe ... [...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. A stay is sometimes used as a synonym for strut, but some sources distinguish that struts are braces for holding compressive forces apart, while stays are braces for keeping stretching forces together. 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 in cases of this genetic condition 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
