COTS Demo Flight 2
SpaceX COTS Demo Flight 2 (COTS 2), also known as Dragon C2+, was the second test-flight for SpaceX's uncrewed Cargo Dragon spacecraft. It launched in May 2012 on the third flight of the company's two-stage Falcon 9 launch vehicle. The flight was performed under a funded agreement from NASA as the second Dragon demonstration mission in the Commercial Orbital Transportation Services (COTS) program. The purpose of the COTS program is to develop and demonstrate commercial sources for cargo re-supply of the International Space Station (ISS). The Dragon C2+ spacecraft was the first American vehicle to visit the ISS since the end of the Space Shuttle program. It was also the first commercial spacecraft to rendezvous and berth with another spacecraft. Initially, the objectives of the C2+ mission were to have been accomplished by two separate missions; Dragon C2 would have carried out a fly-by of the ISS, practiced rendezvous maneuvers and communications with the station, before retu ...

SpaceX Dragon
American private space transportation company SpaceX has developed and produced several spacecraft named Dragon. The first family member, now referred to as Dragon 1, flew 23 cargo missions to the ISS between 2010 and 2020 before being retired. With this first version not designed for carrying astronauts, it was funded by NASA with $396 million awarded through the Commercial Orbital Transportation Services (COTS) program, with SpaceX being announced as a winner of the first round of funding on August 18, 2006. SpaceX developed its Dragon 2 spacecraft starting in 2014, with a cargo version and a crewed version. It entered service in 2019 with the Demo-1 flight, and performed its first flight with astronauts on May 30, 2020, during the Crew Dragon Demo-2 flight. SpaceX also investigated a version named Red Dragon for Mars exploration, but the project did not go forward. A version named Dragon XL Is proposed to provide Gateway Logistics Services to the Lunar Gateway. Name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Canadarm2
The Mobile Servicing System (MSS), is a robotic system on board the International Space Station (ISS). Launched to the ISS in 2001, it plays a key role in station assembly and maintenance; it moves equipment and supplies around the station, supports astronauts working in space, and services instruments and other payloads attached to the ISS and is used for external maintenance. Astronauts receive specialized training to enable them to perform these functions with the various systems of the MSS. The MSS is composed of three components: * the Space Station Remote Manipulator System (SSRMS), known as Canadarm2. * the Mobile Remote Servicer Base System (MBS). * the Special Purpose Dexterous Manipulator (SPDM, also known as "Dextre" or "Canada hand"). The system can move along rails on the Integrated Truss Structure on top of the US provided Mobile Transporter cart which hosts the MRS Base System. The system's control software was written in the Ada 95 programming language. The M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coelliptic Orbit
Summary A simple list of just the common orbit abbreviations. List of abbreviations of common Earth orbits List of abbreviations of other orbits Classifications The following is a list of types of orbits: Centric classifications * Galactocentric orbit: An orbit about the center of a galaxy. The Sun follows this type of orbit about the Galactic Center of the Milky Way. * Heliocentric orbit: An orbit around the Sun. In the Solar System, all planets, comets, and asteroids are in such orbits, as are many artificial satellites and pieces of space debris. Moons by contrast are not in a heliocentric orbit but rather orbit their parent object. * Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites. * Lunar orbit (also selenocentric orbit): An orbit around Earth's Moon. * Areocentric orbit: An orbit around the planet Mars, such as that of its moons or artificial satellites. For orbits centered about planets other than Earth a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draco (rocket Engine Family)
The SpaceX Draco is a hypergolic liquid rocket engine designed and built by SpaceX for use in their space capsules. Two engine types have been built to date: Draco and SuperDraco. The original Draco thruster is a small rocket engine for use on the Dragon spacecraft. SuperDraco uses the same storable (non-cryogenic) hypergolic propellant as the small Draco thrusters, but is much larger and delivers over 100 times the thrust. SuperDraco engines are being used on the Crew Dragon spacecraft to provide launch-escape capability in case of a failure in the launch vehicle. Draco and SuperDraco combine the functions of a reaction control system and main propulsive engine. Draco Draco thrusters generate 400 newtons (90 pounds-force) of thrust using a storable propellant mixture of monomethyl hydrazine fuel and nitrogen tetroxide oxidizer. The Draco thrust is comparable to the Marquardt R-4D engine developed for the Apollo Service and Lunar Modules in the 1960s and used for apogee/pe ...

LIDAR
Lidar (, also LIDAR, or LiDAR; sometimes LADAR) is a method for determining ranges (variable distance) by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It can also be used to make digital 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light. It has terrestrial, airborne, and mobile applications. ''Lidar'' is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. It is also used in control and navigation for som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Data Grapple Fixture
Grapple fixtures are used on spacecraft or other objects to provide a secure connection for a robotic arm. North America The fixtures allowed the Space Shuttle's Canadarm (also known as the Shuttle Remote Manipulator System, or SRMS) to safely grapple large objects (e.g. ISS components, or satellites e.g. HST). They currently do the same for the International Space Station's Space Station Remote Manipulator System (SSRMS) (also known as Canadarm2) and the Japanese Experiment Module Remote Manipulator System (JEMRMS). The grapple fixtures are flat in appearance, with a central grapple pin topped with a sphere which the snares in the end of the arms latch on to. They use three "ramps" that help guide the robotic arm correctly onto the grapple fixture. Development The North American grapple fixture was developed at Spar Aerospace in the 1970s. Its invention is credited to Frank Mee, who also invented the Canadarm end effector for the Space Shuttle. The Grapple Fixture design wa ...

Space Transportation System
The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program. (NASA appropriated the name for its Space Shuttle Program, the only component of the proposal to survive Congressional funding approval). The purpose of the system was two-fold: to reduce the cost of spaceflight by replacing the current method of launching capsules on expendable rockets with reusable spacecraft; and to support ambitious follow-on programs including permanent orbiting space stations around Earth and the Moon, and a human landing mission to Mars. In February 1969, President Richard Nixon appointed a Space Task Group headed by Vice President Spiro Agnew to recommend human space projects beyond Apollo. The group responded in September with the outline of the STS, and three different program levels of effort culminating with a ...

Design Review (US Government)
In the United States military integrated acquisition lifecycle the Technical section has multiple acquisition "Technical Reviews". Technical reviews and audits assist the acquisition and the number and types are tailored to the acquisition. Overall guidance flows from the Defense Acquisition Guidebook chapter 4, with local details further defined by the review organizations. Typical topics examined include adequacy of program/contract metrics, proper staffing, risks, budget, and schedule. In NASA's engineering design life cycle, design reviews are held for technical and programmatic accountability and to authorize the release of funding to a project. A design review provides an in-depth assessment by an independent team of discipline experts and managers that the design (or concept) is realistic and attainable from a programmatic and technical sense. Design review is also required of medical device developers as part of a system of design controls described in the US Food and D ...
