A spacecraft is a vehicle or device designed for spaceflight. Space Shuttle Atlantis ( Orbiter Vehicle Designation: OV-104 is one of the three currently operational orbiters in the Space Shuttle fleet of Mir (Мир which can mean both Peace and World, and was the name given to peasant communes in pre-revolutionary Russia was a Soviet (and Phoenix is a Robotic spacecraft on a Space exploration mission on Mars under the Mars Scout Program. Vehicles, derived from the Latin word vehiculum, are non-living Means of transport. Spaceflight is the use of Space technology to fly a Spacecraft into and through Outer space. On a sub-orbital spaceflight, a spacecraft enters outer space but then returns to the planetary surface (such as Earth) without making a complete orbit. A sub-orbital spaceflight (or sub-orbital flight is a Spaceflight in which the Spacecraft reaches space, but its Trajectory intersects Outer space, often simply called space, comprises the relatively empty regions of the Universe outside the escape velocities of Celestial bodies. A planet, as defined by the International Astronomical Union (IAU is a celestial body Orbiting a Star or stellar remnant that is EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 In Physics, an orbit is the gravitationally curved path of one object around a point or another body for example the gravitational orbit of a planet around a star For an orbital spaceflight, a spacecraft enters a closed orbit around the planetary body. An orbital spaceflight (or orbital flight is a Spaceflight in which a Spacecraft is placed on a trajectory where it could remain in space for at least Spacecraft used for human spaceflights carry people on board as crew or passengers. A human spaceflight is a Spaceflight with a human crew, and possibly passengers Spacecraft used for robotic space missions operate either autonomously or telerobotically. A robotic spacecraft is a Spacecraft with no humans on board that is usually under Telerobotic control Autonomous robots are Robots which can perform desired tasks in unstructured environments without continuous human guidance Telerobotics is the area of Robotics concerned with the control of robots from a distance chiefly using wireless connections (like Wi-Fi, Bluetooth, the Robotic spacecraft that leave the vicinity of the planetary body are space probes. A space probe is a scientific Space exploration mission in which a Robotic spacecraft leaves the Gravity well of Earth and approaches the Robotic spacecraft that remain in orbit around the planetary body are artificial satellites. This article is about artificial satellites For natural satellites also known as moons see Natural satellite. Starships, which are built for interstellar travel, are so far a theoretical concept only. A starship is a theoretical Spacecraft designed for traveling between the stars, as opposed to a vehicle designed for Orbital spaceflight or Interplanetary Interstellar space travel is unmanned or manned Travel between Stars The concept of interstellar travel in Starships is a staple in Science fiction

Spacecraft are used for a variety of purposes, including communications, earth observation, meteorology, navigation, planetary exploration and space tourism. Earth observation satellites are Satellites specifically designed to observe Earth from Orbit, similar to Reconnaissance satellites but intended A weather satellite is a type of Satellite that is primarily used to monitor the Weather and Climate of the Earth. Navigation is the process of reading and controlling the movement of a craft or vehicle from one place to another Planetary science, also known as planetology and closely related to planetary astronomy, is the Science of Planets or Planetary systems Space tourism is the recent Phenomenon of tourists paying for flights into space pioneered by Russia Spacecraft and space travel are common themes in works of science fiction. Spaceflight is the use of Space technology to fly a Spacecraft into and through Outer space.

Spacecraft subsystems

A spacecraft system comprises various subsystems, dependent upon mission profile. Spacecraft subsystems may include: attitude determination and control (variously called ADAC, ADC or ACS), guidance, navigation and control (GNC or GN&C), communications (COMS), command and data handling (CDH or C&DH), power (EPS), thermal control (TCS), propulsion, structures, and payload.

Life support 
Spacecraft intended for human spaceflight must also include a life support system for the crew. In Human spaceflight, the life support system is a group of devices that allow a human being to survive in outer space
Attitude control 
Spacecraft need an attitude control subsystem to be correctly oriented in space and respond to external torques and forces properly. The attitude of a body is its orientation as perceived in a certain Frame of reference; providing a vector along which a spacecraft is pointing is a description of its attitude A torque (τ in Physics, also called a moment (of force is a pseudo- vector that measures the tendency of a force to rotate an object about The attitude control subsystem consists of sensors and actuators, together with controlling algorithms. A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument An actuator is a mechanical device for moving or controlling a mechanism or system The attitude control subsystem permits proper pointing for the science objective, sun pointing for power to the solar arrays and earth-pointing for communications.
GNC 
Guidance refers to the calculation of the commands (usually done by the CDH subsystem) needed to steer the spacecraft where it is desired to be. Navigation means determining a spacecraft's orbital elements or position. The elements of an orbit are the parameters needed to specify that Orbit uniquely given a model of two point-masses obeying the Newtonian laws of motion and the Control means adjusting the path of the spacecraft to meet mission requirements. On some missions, GNC and Attitude Control are combined into one subsystem of the spacecraft.
Command and data handling 
The CDH subsystem receives commands from the communications subsystem, performs validation and decoding of the commands, and distributes the commands to the appropriate spacecraft subsystems and components. The CDH also receives housekeeping data and science data from the other spacecraft subsystems and components, and packages the data for storage on a solid state recorder or transmission to the ground via the communications subsystem. Other functions of the CDH include maintaining the spacecraft clock and state-of-health monitoring.
Power 
Spacecraft need an electrical power generation and distribution subsystem for powering the various spacecraft subsystems. For spacecraft near the Sun, solar panels are frequently used to generate electrical power. The Sun (Sol is the Star at the center of the Solar System. Spacecraft operating in the inner Solar system usually rely on the use of Photovoltaic solar panels to derive electricity from Sunlight. Spacecraft designed to operate in more distant locations, for example Jupiter, might employ a Radioisotope Thermoelectric Generator (RTG) to generate electrical power. A radioisotope thermoelectric generator ( RTG, RITEG) is an Electrical generator which obtains its power from Radioactive decay. Electrical power is sent through power conditioning equipment before it passes through a power distribution unit over an electrical bus to other spacecraft components. Batteries are typically connected to the bus via a battery charge regulator, and the batteries are used to provide electrical power during periods when primary power is not available, for example when a Low Earth Orbit (LEO) spacecraft is eclipsed by the Earth. A Low Earth Orbit (LEO is generally defined as an Orbit within the locus extending from the Earth’s surface up to an altitude of 2000 km For other possible meanings of the terms "eclipse" and "eclipsed" see eclipse.
Thermal control 
Spacecraft must be engineered to withstand transit through the Earth's atmosphere and the space environment. Temperature and layers The temperature of the Earth's atmosphere varies with altitude the mathematical relationship between temperature and altitude varies among five Space environment is a branch of Astronautics, Aerospace engineering and Astronomy that seeks to understand and address conditions existing in space that They must operate in a vacuum with temperatures potentially ranging across hundreds of degrees Celsius as well as (if subject to reentry) in the presence of plasmas. This vacuum means "absence of matter" or "an empty area or space" for the cleaning appliance see Vacuum cleaner. The Celsius Temperature scale was previously known as the centigrade scale. Material requirements are such that either high melting temperature, low density materials such as Be and C-C or (possibly due to the lower thickness requirements despite its high density) W or ablative C-C composites are used. Depending on mission profile, spacecraft may also need to operate on the surface of another planetary body. The thermal control subsystem can be passive, dependent on the selection of materials with specific radiative properties. Active thermal control makes use of electrical heaters and certain actuators such as louvers to control temperature ranges of equipments within specific ranges. An actuator is a mechanical device for moving or controlling a mechanism or system
A launch vehicle, like this Proton rocket, is typically used to bring a spacecraft to orbit.
A launch vehicle, like this Proton rocket, is typically used to bring a spacecraft to orbit. In Spaceflight, a launch vehicle or carrier rocket is a Rocket used to carry a payload from the Earth's surface into Outer space. The Proton rocket In Physics, an orbit is the gravitationally curved path of one object around a point or another body for example the gravitational orbit of a planet around a star
Propulsion 
Spacecraft may or may not have a propulsion subsystem, depending upon whether or not the mission profile calls for propulsion. Spacecraft propulsion is any method used to change the velocity of Spacecraft and artificial Satellites There are many different methods The Swift spacecraft is an example of a spacecraft that does not have a propulsion subsystem. The Swift Gamma-Ray Burst Mission consists of a Robotic spacecraft called Swift, which was launched into Orbit on November 20, 2004 Typically though, LEO spacecraft (for example Terra (EOS AM-1) include a propulsion subsystem for altitude adjustments (called drag make-up maneuvers) and inclination adjustment maneuvers. Inclination in general is the Angle between a Reference plane and another plane or axis of direction A propulsion system is also needed for spacecraft that perform momentum management maneuvers. Components of a conventional propulsion subsystem include fuel, tankage, valves, pipes, and thrusters. The TCS interfaces with the propulsion subsystem by monitoring the temperature of those components, and by preheating tanks and thrusters in preparation for a spacecraft maneuver.
Structures 
Spacecraft must be engineered to withstand launch loads imparted by the launch vehicle, and must have a point of attachment for all the other subsystems. Depending upon mission profile, the structural subsystem might need to withstand loads imparted by entry into the atmosphere of another planetary body, and landing on the surface of another planetary body. An atmosphere (from Greek ατμός - atmos, " Vapor " + σφαίρα - sphaira, " Sphere "
Payload 
The payload is dependent upon the mission of the spacecraft, and is typically regarded as the part of the spacecraft "that pays the bills". Typical payloads could include scientific instruments (cameras, telescopes, or particle detectors, for example), cargo, or a human crew. A camera is a device used to capture images either as still Photographs or as sequences of moving images ( Movies or Videos. A telescope is an instrument designed for the observation of remote objects and the collection of Electromagnetic radiation. In experimental and applied Particle physics and Nuclear engineering, a particle detector, also known as a radiation detector, is a device used to A human spaceflight is a Spaceflight with a human crew, and possibly passengers
Ground segment 
The ground segment, though not technically part of the spacecraft, is vital to the operation of the spacecraft. Typical components of a ground segment in use during normal operations include a mission operations facility where the flight operations team conducts the operations of the spacecraft, a data processing and storage facility, ground stations to radiate signals to and receive signals from the spacecraft, and a voice and data communications network to connect all mission elements. [1]
Launch vehicle 
The launch vehicle is used to propel the spacecraft from the Earth's surface, through the atmosphere, and into an orbit, the exact orbit being dependent upon mission configuration. In Spaceflight, a launch vehicle or carrier rocket is a Rocket used to carry a payload from the Earth's surface into Outer space. An atmosphere (from Greek ατμός - atmos, " Vapor " + σφαίρα - sphaira, " Sphere " In Physics, an orbit is the gravitationally curved path of one object around a point or another body for example the gravitational orbit of a planet around a star The launch vehicle may be expendable or reusable. An expendable launch system is a Launch system that uses an expendable launch vehicle (ELV to carry a payload into Space. A reusable launch system (or reusable launch vehicle, RLV is a Launch system which is capable of launching a Launch vehicle into space more than once

The Space Shuttle Columbia disaster occurred on February 1, 2003, when the Space Shuttle ''Columbia'' disintegrated over Texas

The first automatic partially reusable spacecraft was the Buran (Snowstorm), launched by the USSR on November 15, 1988, although it made only one flight. The Buran spacecraft ( Буран "Snowstorm" or "Blizzard") GRAU index 11F35 K1, was the only fully completed and operational Events 655 - Battle of Winwaed: Penda of Mercia is defeated by Oswiu of Northumbria.

A spaceplane is a Rocket plane designed to pass the Edge of space. S. Space Shuttle, although its drop-off boosters used liquid propellants and its main engines were located at the base of what would be the external tank in the American Shuttle. Lack of funding, complicated by the dissolution of the USSR, prevented any further flights of Buran. The Space Shuttle has since been modified to allow for autonomous re-entry via the addition of a control cable running from the control cabin to the mid-deck which would allow for the automated deployment of the landing gear in the event a un-crewed re-entry was required following abandonment due to damage at the ISS.

Per the Vision for Space Exploration, the Space Shuttle is due to be retired in 2010 due mainly to its old age and high cost of program reaching over a billion dollars per flight. The Vision for Space Exploration is the United States space policy announced on January 14, 2004 by U The Shuttle's human transport role is to be replaced by the partially reusable Crew Exploration Vehicle (CEV) no later than 2014. The Crew Exploration Vehicle (or CEV) was the conceptual component of the Vision for Space Exploration that later became known as the Orion spacecraft The Shuttle's heavy cargo transport role is to be replaced by expendable rockets such as the Evolved Expendable Launch Vehicle (EELV) or a Shuttle Derived Launch Vehicle. The Evolved Expendable Launch Vehicle ( EELV) program is a United States government, primarily a Department of Defense –sponsored effort begun in the The Shuttle-Derived Launch Vehicle, or simply Shuttle-Derived Vehicle (SDV, is a term describing one of a wide array of concepts that have been developed for creating space

Fictional spacecraft

The term spacecraft is mainly used to refer to spacecraft that are real or conceived using present technology. The terms spaceship and starship are generally applied only to fictional spacecraft, usually those capable of transporting people. This is a list of fictional Spacecraft, Starships and exo-atmospheric vessels that have been identified by name in published works of fiction (novels films television series A starship is a theoretical Spacecraft designed for traveling between the stars, as opposed to a vehicle designed for Orbital spaceflight or Interplanetary Transport or transportation is the movement of people and goods from one place to another The spaceship is one of the prime elements in science fiction. Numerous short stories and novels are built up around various ideas for spacecraft, and spacecraft have often been featured in movies. The short story is a literary genre of Fictional Prose Narrative that tends to be more concise and to the point than longer works of fiction such A novel (from Italian novella, Spanish novela, French nouvelle for "new" "news" or "short story Some hard science fiction books focus on the technical details of the craft, while others treat the spacecraft as a given and delve little into its actual implementation. Hard science fiction is a category of Science fiction characterized by an emphasis on scientific or technical detail or on scientific accuracy or on both A Book is a set or collection of written printed illustrated or blank sheets made of Paper, Parchment, or other material usually fastened together
