Leonardo Multi-Purpose Logistics Module
The ''Leonardo'' Permanent Multipurpose Module (PMM) is a module of the International Space Station. It was flown into space aboard the Space Shuttle ''Discovery'' on STS-133 on 24 February 2011 and installed on 1 March. ''Leonardo'' is primarily used for storage of spares, supplies and waste on the ISS, which was until then stored in many different places within the space station. It is also the personal hygiene area for the astronauts who live in the US Orbital Segment. The ''Leonardo'' PMM was a Multi-Purpose Logistics Module (MPLM) before 2011, then was modified into its current configuration. It was formerly one of two MPLM used for bringing cargo to and from the ISS with the Space Shuttle. The module was named for Italian polymath Leonardo da Vinci. Like the other Multi-Purpose Logistics Modules, it was constructed by the Italian Space Agency, who chose to name it after Leonardo da Vinci. Construction began in April 1996, and the module was delivered to NASA at the Kennedy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-133 ISS-26 Permanent Multipurpose Module
STS-133 ( ISS assembly flight ULF5) was the 133rd mission in NASA's Space Shuttle program; during the mission, Space Shuttle ''Discovery'' docked with the International Space Station. It was ''Discovery'''s 39th and final mission. The mission launched on 24 February 2011, and landed on 9 March 2011. The crew consisted of six American astronauts, all of whom had been on prior spaceflights, headed by Commander Steven Lindsey. The crew joined the long-duration six person crew of Expedition 26, who were already aboard the space station. About a month before lift-off, one of the original crew members, Tim Kopra, was injured in a bicycle accident. He was replaced by Stephen Bowen. The mission transported several items to the space station, including the Permanent Multipurpose Module ''Leonardo'', which was left permanently docked to one of the station's ports. The shuttle also carried the third of four ExPRESS Logistics Carriers to the ISS, as well as a humanoid robot called Robonau ...

Nadir
The nadir (, ; ar, نظير, naẓīr, counterpart) is the direction pointing directly ''below'' a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface. The direction opposite of the nadir is the zenith. Definitions Space science Since the concept of ''being below'' is itself somewhat vague, scientists define the nadir in more rigorous terms. Specifically, in astronomy, geophysics and related sciences (e.g., meteorology), the nadir at a given point is the local vertical direction pointing in the direction of the force of gravity at that location. The term can also be used to represent the lowest point that a celestial object reaches along its apparent daily path around a given point of observation (i.e. the object's ''lower culmination''). This can be used to describe the position of the Sun, but it is only technically accurate for one latitude at a time and only possible at the low latitudes. T ...

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and racing sails to bulletproof vests, all due to its high tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact; and for mooring lines and other underwater applications. A similar fiber called Twaron with the same chemical structure was developed by Akzo in the 1970s; commercial production started in 1986, and Twaron is now manufactured by Teijin.

Multi-layer Insulation
Multi-layer insulation (MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, MLI is one of the main items of the spacecraft thermal design, primarily intended to reduce heat loss by thermal radiation. In its basic form, it does not appreciably insulate against other thermal losses such as heat conduction or convection. It is therefore commonly used on satellites and other applications in vacuum where conduction and convection are much less significant and radiation dominates. MLI gives many satellites and other space probes the appearance of being covered with gold foil which is the effect of the amber-coloured Kapton layer deposited over the silver Aluminized mylar. For non-spacecraft applications, MLI works only as part of a vacuum insulation system. For use in cryogenics, wrapped MLI can be installed inside the annulus of vacuum jacketed pipes. MLI may also be combined with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whipple Shield
The Whipple shield or Whipple bumper, invented by Fred Whipple, is a type of hypervelocity impact shield used to protect crewed and uncrewed spacecraft from collisions with micrometeoroids and orbital debris whose velocities generally range between . According to NASA, the Whipple shield is designed to withstand collisions with debris up to 1 cm, which helps to mitigate the Kessler syndrome. Shield In contrast to monolithic shielding of early spacecraft, Whipple shields consist of a relatively thin outer bumper spaced some distance from the main spacecraft wall. The bumper is not expected to stop the incoming particle or even remove much of its energy, but to break up and disperse it, dividing the original particle energy among many fragments that fan out between bumper and wall. The original particle energy is spread more thinly over a larger wall area, which is more likely to withstand it. A direct analogy is that a lighter bullet resistant vest is needed to stop a load ...

Common Berthing Mechanism
The Common Mechanism (CBM) connects habitable elements in the US Orbital Segment (USOS) of the International Space Station (ISS). The CBM has two distinct sides that, once mated, form a cylindrical vestibule between modules. The vestibule is about long and across. At least one end of the vestibule is often limited in diameter by a smaller bulkhead penetration. The elements are maneuvered to the berthing-ready position by a . Latches and bolts on the Active CBM (ACBM) side pull fittings and floating nuts on the Passive CBM (PCBM) side to align and join the two. After the vestibule is pressurized, crew members clear a passage between modules by removing some CBM components. Utility connectors are installed between facing bulkheads, with a closeout panel to cover them. The resulting tunnel can be used as a loading bay, admitting large payloads from visiting cargo spacecraft that would not fit through a typical personnel passageway.

Axiom Station
Axiom Orbital Segment or Axiom Segment (or AxS) are the planned modular components of the International Space Station (ISS) designed by Axiom Space for commercial space activities. Axiom Space gained initial NASA approval for the venture in January 2020. Axiom Space was later awarded the contract by NASA on February 28, 2020. This orbital station will be separated from the ISS to become its own modular space station, Axiom Station, after the ISS is decommissioned. Axiom Segment At least four Axiom modules will attach to the International Space Station. The first module is scheduled to be launched in late 2025 and would dock to the forward port of ''Harmony'', requiring relocation of Pressurized Mating Adapter (PMA-2) to any other ports on ISS like Harmony nadir. Axiom Space plans to attach at least three additional modules to its first core module, and send private astronauts to inhabit the modules. Axiom renderings illustrate how the four modules might attach to the ISS a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathing
Bathing is the act of washing the body, usually with water, or the immersion of the body in water. It may be practiced for personal hygiene, religious ritual or therapeutic purposes. By analogy, especially as a recreational activity, the term is also applied to sun bathing and sea bathing. People bathe at a range of temperatures, according to custom or purpose, from very cold to very hot. In the western world, bathing is usually done at comfortable temperatures in a bathtub or shower. This type of bathing is done more or less daily for hygiene purposes. A ritual religious bath is sometimes referred to as immersion or baptism. The use of water for therapeutic purposes can be called a water treatment or hydrotherapy. Recreational water activities are also known as swimming and paddling. History Ancient world Throughout history, societies devised systems to enable water to be brought to population centers. The oldest accountable daily ritual of bathing can be traced to the ...

Commercial Crew Development
Development of the Commercial Crew Program began in the second round of the Commercial Crew Development (CCDev) program, which was rescoped from a technology development program for human spaceflight to a competitive development program that would produce the spacecraft to be used in the Commercial Crew Program to provide crew transportation services to and from the International Space Station (ISS). To implement the program NASA awarded a series of competitive fixed-price contracts to private vendors starting in 2011. Operational contracts to fly astronauts were awarded in September 2014 to SpaceX and Boeing. Each company performed an uncrewed orbital test flight in 2019, and operational flights started in November 2020. SpaceX's Crew Dragon Demo-1 2019 flight of Dragon 2 arrived at the International Space Station in March 2019 and returned via splashdown in the Atlantic Ocean. After completion of its test series, a Crew Dragon spacecraft made its first operational Commercial Cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
