Mammalia refers to the class sub-category used in the scientific classification of animals. Mammals are members of a class of air-breathing vertebrate animals characterised by the possession of endothermy, hair, three middle ear bones, and mammary glands functional in mothers with young. Most mammals also possess sweat glands and specialised teeth, and the largest group of mammals, the placentals, have a placenta which feeds the offspring during gestation. The mammalian brain, with its characteristic neocortex, regulates endothermic and circulatory systems, the latter featuring red blood cells lacking nuclei and a large four-chambered heart maintaining the very high metabolism rate they have. Mammals range in size from the 30–40 millimeter (1- to 1.5-inch) Bumblebee Bat to the 33-meter (108-foot) Blue Whale.

Medical laboratory

Bacta Tank

A medical laboratory is a facility staffed by trained professionals for the treatment of patients and the study of infectious diseases. Medical laboratories may exist as either independent institutions or associated with larger medical treatment centers such as hospitals and clinics. Pharmaceutical companies and other R&D firms will usually own one or more medical laboratories, though these labs are almost always a detached facility and not part of the company's corporate headquarters. Many science fiction stories deal with themes relating to medical science.

A mercenary is an armed combat specialist who hires out his or her services for the sake of profit. Most mercenaries hail from a military background and are usually skilled in multiple fighting techniques such as hand-to-hand combat, firearms, aerial combat, vehicular combat, etc. Some mercenaries may also employ themselves as bounty hunters, collecting reward money for capturing escaped refugees. By and large, the most effective mercenaries are of low moral character and have no compunctions against taking the life of a living being if the mission calls for it. Ultimately however, their actions and allegiances are almost always prioritized by how much they are getting paid for their services.

TOS 1x00 027

A merchant is a business person who trades in commodities that he or she did not produce himself, in order to earn a profit. Merchants can be one of two types:

  1. A wholesale merchant operates in the chain between producer and retail merchant. Some wholesale merchants only organize the movement of goods rather than move the goods themselves.
  2. A retail merchant or retailer, sells commodities to consumers (including businesses). A shop owner is a retail merchant.

A merchant class characterizes many pre-modern societies. Its status can range from high (the members even eventually achieving titles such as that of merchant prince to low, as in Chinese culture, owing to the presumed distastefulness of profiting from "mere" trade rather than from labor or the labor of others as in agriculture and craftsmanship.

A meteorite is a natural object originating in outer space that survives impact with the Earth's surface. Most meteorites derive from small astronomical objects called meteoroids, but they are also sometimes produced by impacts of asteroids. When it enters the atmosphere, impact pressure causes the body to heat up and emit light, thus forming a fireball, also known as a meteor or shooting/falling star.
(See Also: Meteoroid)
[top] [Edit Meteorite]


A meteoroid is a sand- to boulder-sized particle of debris in the Solar System. The visible path of a meteoroid that enters Earth's (or another body's) atmosphere is called a meteor, or colloquially a shooting star or falling star. If a meteor reaches the ground and survives impact, then it is called a meteorite. Many meteors appearing seconds or minutes apart are called a meteor shower. Meteors typically occur in the mesosphere, and most range in altitude from 75 km to 100 km. Millions of meteors occur in the Earth's atmosphere every day. Most meteoroids that cause meteors are about the size of a pebble.

Mid Rim

Mid Rim refers to a region of space within a charted area of a galaxy. It's location is halfway between the center of the galaxy and the farthest known reaches of outer space. It is sometimes referred to as the Inner Rim. Sectors of space that are farther away from the center of the galaxy are often referred to as the Outer Rim or other ambiguous terms such as Wild Space, the Badlands or the Expansion Region. Worlds within Mid Rim stellar/planetary systems are often rich in resources and have a high volume of trade routes and commerce centers. Many colony worlds can be found within Mid Rim systems. However, they are generally not as densely populated as Core World planets, which usually forms the backbone of interstellar commerce within a galaxy.

Mission Control Center

IASA 001

A Mission Control Center (MCC) is an entity that manages aerospace vehicle flights. The MCC is often part of a national aerospace agency or a large aerospace company. There are several such national agencies in the world, the top four being

  • National Aeronautics and Space Administration (NASA)
  • Russian Federal Space Agency (RKA)
  • China National Space Administration (CNSA)
  • European Space Agency (ESA)

Some fictional space agencies include the International Aeronautics and Space Administration (pictured above) from the Farscape, Starfleet Command from the Star Trek mythos and the eponymous Stargate Command from the Stargate franchise.

A moon or natural satellite is a celestial body that orbits a planet or smaller body. Technically the term natural satellite could refer to a planet orbiting a star, or a dwarf galaxy orbiting a major galaxy, but it is normally synonymous with moon and used to identify non-artificial satellites of planets, dwarf planets, and minor planets.

"Moon" is also the first name of actress Moon Bloodgood, who played Doctor Anne Glass on the TNT series Falling Skies.

Mutated human

A mutated human is an individual who is born as a normal human being, but through external circumstances throughout their developmental cycle or even later in life, find themselves mutated on a physical and/or physiological level. Another word used to describe such a being is a mutant, but some variations of mutants may also be individuals who are born with certain physical deformities or disabilities. There are many different situations that may cause physical or genetic mutation. In speculative fiction, the most common circumstances are either exposure to a dangerous element or environment or scientific experimentation.
