Node 4
Node 4, also known as the Docking Hub System (DHS), was a proposed module of the International Space Station (ISS). In 2011 NASA was considering a 40-month design and development effort for Node 4 that would result in its launch in late 2013. Node 4 would have been built using the Node Structural Test Article (STA) and docked to the forward port of the ''Harmony'' module. The Structural Test Article was built to facilitate testing of ISS hardware and was intended to become Node 1. However, during construction, structural design flaws were discovered. The under-construction Node 2 was renamed Node 1 and the STA (ex-Node 1) was put into storage at the Kennedy Space Center (KSC). Since the Space Shuttle program was retired, had a decision to build and launch Node 4 been taken, it would have been launched by an Atlas V or Delta IV rocket. In December 2011 Boeing proposed using Node 4 as the core of an Exploration Gateway Platform to be constructed at the ISS and relocated via spa ...

ISS Node STA
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 be i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagrange Point
In celestial mechanics, the Lagrange points (; also Lagrangian points or libration points) are points of equilibrium for small-mass objects under the influence of two massive orbiting bodies. Mathematically, this involves the solution of the restricted three-body problem in which two bodies are far more massive than the third. Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of whatever is at that point. At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal force balance each other. This can make Lagrange points an excellent location for satellites, as few orbit corrections are needed to maintain the desired orbit. Small objects placed in orbit at Lagrange points are in equilibrium in at least two directions relative to the center of mass of the large bodies. For any combination of two orbital bodies there are five Lagrange points, L1 to L5, all in the orbital plane of the two lar ...

ISS Propulsion Module
The ISS Propulsion module, functions performed by the Zvezda (ISS module), Zvezda Service Module and Progress (spacecraft), Progress spacecraft. Critical ISS functionality such as guidance, navigation, control and propulsion are provided only by Russian (Zvezda and Progress) and the European (Automated Transfer Vehicle, ATV) spacecraft. A Propulsion Module would have been needed for ISS altitude maintenance and reboost, debris avoidance maneuvers, attitude control and propellant supply in the event the Zvezda Service Module was not available (launch failure, etc.) to the International Space Station. If the Zvezda had not been available, the Interim Control Module would have been used at first. It only had a lifetime of three years; then the Propulsion Module would have been necessary. History The ISS requires an average 7,000 kg of propellant each year for altitude maintenance, debris avoidance and attitude control. A Propulsion Module would have provided reserve propellant f ...

Shuttle Landing Facility
The Shuttle Landing Facility (SLF) also known as Launch and Landing Facility (LLF) is an airport located on Merritt Island in Brevard County, Florida, United States. It is a part of the Kennedy Space Center and was used by Space Shuttle for landing until July 2011. It was also used for takeoffs and landings for NASA training jets such as the Shuttle Carrier Aircraft and for civilian aircraft. Starting in 2015, Space Florida manages and operates the facility under a 30-year lease from NASA. In addition to ongoing use by NASA, private companies have been utilizing the SLF since the 2011 end of the Space Shuttle program. Facilities The Shuttle Landing Facility covers and has a single runway, 15/33. It is one of the longest runways in the world, at , and is wide. (Despite its length, astronaut Jack R. Lousma stated that he would have preferred the runway to be "half as wide and twice as long") Additionally, the SLF has of paved overruns at each end. The Mate-Demate Device ...

Space Station Processing Facility
The Space Station Processing Facility (SSPF) is a three-story industrial building at Kennedy Space Center for the manufacture and processing of flight hardware, modules, structural components and solar arrays of the International Space Station, and future space stations and commercial spacecraft. It was built in 1992 at the space complex's industrial area, just east of the Operations and Checkout Building. The SSPF includes two processing bays, an airlock, operational control rooms, laboratories, logistics areas for equipment and machines, office space, a ballroom and conference halls, and a cafeteria. The processing areas, airlock, and laboratories are designed to support non-hazardous Space Station and Space Shuttle payloads in 100,000 class clean work areas. The building has a total floor area of .

MPLM
A Multi-Purpose Logistics Module (MPLM) is a large pressurized container that was used on Space Shuttle missions to transfer cargo to and from the International Space Station (ISS). Two MPLMs made a dozen trips in the Shuttle cargo bay and initially berthed to the ''Unity'' module and later the ''Harmony'' module on the ISS. From there, supplies were offloaded, and finished experiments and waste were reloaded. The MPLM was then reberthed in the Shuttle for return to Earth. Three modules were built by the Italian Space Agency (ASI): ''Leonardo'', ''Raffaello'', and ''Donatello''. The ''Leonardo'' module was modified in 2010 to turn it into the Permanent Multipurpose Module (PMM) and was permanently attached to the ISS during the STS-133 mission in March 2011. In July 2011, the ''Raffaello'' module was the primary payload on the final Space Shuttle mission. It returned with the Shuttle and was stored at the Kennedy Space Center. The ''Donatello'' module never launched. MP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propellant Depot
An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration. Many different depot concepts exist depending on the type of fuel to be supplied, location, or type of depot which may also include a propellant tanker that delivers a single load to a spacecraft at a specified orbital location and then departs. In-space fuel depots are not necessarily located near or at a space station. Potential users of in-orbit refueling and storage facilities include List of space agencies, space agencies, defense ministries and communications satellite or other private spaceflight, commercial companies. Satellite servicing depots would extend the lifetime of satellites that have nearly consumed all of their orbital maneuvering fuel and are likel ...

Space Launch System
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle developed by NASA. As of 2022, SLS has the highest payload capacity of any rocket in operational service, as well as the greatest liftoff thrust of any rocket in operation. As the primary launch vehicle of the Artemis moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first uncrewed launch, Artemis 1, took place on 16 November 2022. Development of SLS began in 2011, as a replacement for the retired Space Shuttle as well as the cancelled Ares I and Ares V launch vehicles. As a Shuttle-derived vehicle, the Space Launch System reuses hardware from the Space Shuttle program, including the Space Shuttle Solid Rocket Booster, solid rocket boosters and RS-25, RS-25 first stage engines. An original flight date of late 2016 was delayed by nearly 6 years. The SLS program has Space Launch System#Criticism, attracted criticism for such de ...

Apollo Lunar Module
The Apollo Lunar Module (LM ), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only crewed vehicle to land anywhere beyond Earth. Structurally and aerodynamically incapable of flight through Earth's atmosphere, the two-stage lunar module was ferried to lunar orbit attached to the Apollo command and service module (CSM), about twice its mass. Its crew of two flew the complete lunar module from lunar orbit to the Moon's surface. During takeoff, the spent descent stage was used as a launch pad for the ascent stage which then flew back to the command module, after which it was also discarded. Overseen by Grumman, the LM's development was plagued with problems that delayed its first uncrewed flight by about ten months and its first crewed ...

Exploration Gateway Platform
The Exploration Gateway Platform was a design concept proposed by Boeing in December 2011 to drastically reduce the cost of Moon, near Earth asteroids (NEAs), or Mars missions by using components already designed to construct a refueling depot and servicing station located at one of the Earth–Moon Lagrange points, L1 or L2. The system claims its cost savings based on an ability to be reused for multiple missions such as a launch platform for deep space exploration, robotic relay station for moon rovers, telescope servicing and a deep space practice platform located outside the Earth's protective radiation belts. The platform would be constructed at the International Space Station (ISS) for testing before being relocated to EM-L1 or EM-L2 via electric or chemical propulsion rockets. Construction The Platform would consist of parts left over from the ISS program. Parts under consideration were Node 4 to form the main connection point, parts from the Space Shuttle's Orbital Maneu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
