Spacecraft Technology

Space technology is technology for use in outer space, in travel (astronautics) or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation. Space technology includes space vehicles such as spacecraft, satellites, space stations and orbital launch vehicles; deep-space communication; in-space propulsion; and a wide variety of other technologies including support infrastructure equipment, and procedures. The space environment is a sufficiently novel environment that attempting to work in it often requires new tools and techniques.

Space weather is a branch of space physics and aeronomy concerned with the time-varying conditions within the Solar System, including the solar wind, emphasizing the space surrounding the Earth, including conditions in the magnetosphere, ionosphere, and thermosphere.  Space weather is distinct from the terrestrial weather of the Earth's atmosphere troposphere and stratosphere. The science of space weather is focused on fundamental research and practical applications. The term space weather was first used in the 1950s and came into common usage in the 1990s
