Spacecraft are vehicles designed to travel and operate in outer space, from satellites orbiting Earth to manned space vehicles like the Moon-landing Lunar Module and robotic probes exploring other planets.
Spacecraft are typically composed of seven engineering subsystems: Structure, Attitude Determination and Control, Onboard Data Handling, Communication, Power Management Thermal Propulsion Propulsion Payload
Spacecraft are vehicles designed to travel through the harsh conditions of outer space. Their functions vary, depending on the function they were intended to fulfill; such as maintaining timing, interpreting commands uplinked from Earth, collecting and formatting telemetry data for return back home as well as high-level fault protection and safety routines.
The power subsystem of a spacecraft provides electrical energy needed for its systems. This may come from solar panels or batteries. If intended to land on another planet, aeroshells and parachutes may also be provided to slow its free-fall descent.
An inhabited spacecraft like the Shuttle or Soyuz requires a crew compartment and life support systems, often divided between reentry module and service module to house propulsion system, power supply and life support components respectively.
Spacecraft are vehicles designed to explore space, with uses including communication, observation of Earth and meteorology observations, navigation and exploration as well as transport of people or cargo on human spaceflights. Spacecraft may either be manned or unmanned and space stations require complex equipment as well as power for operation.
Satellites make up most spacecraft, orbiting Earth and other planets in orbit. Some drum-shaped satellites may rotate to keep themselves stable in space; most box-shaped satellites do not spin. Some satellites even feature solar ‘wings’ for power generation onboard.
