material entity material entity Payload https://en.wikipedia.org/w/index.php?title=Payload&oldid=1035953573 https://www.commoncoreontologies.org/ArtifactOntology A Material Entity that is transported by a Vehicle during an Act of Location Change for the purpose of being delivered to or performing one or more functions at a predefined location. Depending on the nature of the Flight or Mission, the Payload of a Vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment. Extra fuel, when optionally carried, is also considered part of the payload. In each case, the Payload is what provides the immediate reason for performing the Act of Location Change (e.g. transporting the passengers of a commercial airline flight to their destination; transporting food, fuel, oxygen, research equipment, and spare parts to the International Space Station; or conveying an array of sensors, cameras, and communications systems so they can operate during a Sun-Synchronous Earth Orbit).
