Tranquility (ISS module)

Tranquility, also known as Node 3, is a module of the International Space Station (ISS). ESA and the Italian Space Agency had Tranquility built by Thales Alenia Space. A ceremony on November 20, 2009 transferred ownership of the module to NASA. On February 8, 2010, NASA launched the module on the Space Shuttle's STS-130 mission.

The module provides six berthing locations, but three of those locations are disabled, as modules originally planned to be attached to Tranquility were canceled. STS-130 also brought the Cupola, a large window module and robotics work station to the ISS, which was then attached to the nadir-side of Tranquility. The module also includes various ISS systems, including additional life support systems.

Design

Tranquility was built within the ESA-NASA ISS bartering system. ESA committed to build and fund both Harmony and Tranquility as well as the ATV in order to use NASA ISS facitilies, fly astronauts on the Shuttle and for other ISS services. ESA teamed up with the Italian Space Agency ASI to build both Harmony and Tranquility at Thales Alenia Space in Turin.

Tranquillity

Tranquillity (also spelled tranquility) is the quality or state of being tranquil; that is, calm, serene, and worry-free. The word tranquillity appears in numerous texts ranging from the religious writings of Buddhism, where the term passaddhi refers to tranquillity of the body, thoughts and consciousness on the path to enlightenment, to an assortment of policy and planning guidance documents, where interpretation of the word is typically linked to engagement with the natural environment.

Benefits

Psychological Being in a tranquil or ‘restorative’ environment allows individuals to take respite from the periods of sustained ‘directed attention’ that characterise modern living. In developing their Attention Restoration Theory (ART), Kaplan and Kaplan proposed that recovery from cognitive overload could most effectively be achieved by engaging with natural restorative environments, that are away from daily distractions and have the extent and mystery that allows the imagination to wander, thereby enabling individuals to engage effortlessly with their surroundings. The theory works on the principle that the amount of reflection possible within such an environment depends upon the type of cognitive engagement, i.e. fascination; that the environment holds. ‘Soft fascination’ is deemed to occur when there is enough interest in the surroundings to hold attention but not so much that it compromises the ability to reflect. In essence, soft fascination, which has been taken by Herzog and Pheasant as a reasonable term to describe tranquillity, provides a pleasing level of sensory input that involves no cognitive effort other than removing oneself from an overcrowded mental space.

International Space Station

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest artificial body in orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets as well as American Space Shuttles.

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.

List of Foundation universe planets

This is a list of Foundation universe planets featured or mentioned in the Robot series, Empire series, and Foundation series created by Isaac Asimov.

61 Cygni

The star system 61 Cygni, in the Sirius Sector, is advanced by Lord Dorwin as the potential site for a planet of origin for the human species. Lord Dorwin cites 'Sol' (meaning Earth's Sun) and three other planetary systems in the Sirius Sector, along with Arcturus in the Arcturus Sector, as potential original worlds. (This fact seems to be contradicted by information given in Foundation and Earth). Claims were made as early as 1942 that 61 Cygni had a planetary system, though to date, none has been verified, and Asimov was aware of these claims.

Alpha

Alpha is a fictional planet orbiting the larger of the two stars in the Alpha Centauri system.

In Asimov's Foundation Series, Alpha Centauri is cited by Lord Dorwin as one of the solar systems where humankind potentially originated. The others are Sol, Sirius, 61 Cygni and Arcturus. Beyond mentioning that it is in the Sirius Sector, Dorwin gives no further details.

Modularity

Modularity is the degree to which a system's components may be separated and recombined. The meaning of the word, however, can vary somewhat by context:
