ESA programme starting in 2009. The objective of the Space Situational Awareness (SSA) system is to support the European independent utilisation of and access to space for research or services, throug
h providing timely and quality data, information, services and knowledge regarding the environment, the threats, and the sustainable exploitation of the outer space.
A telescope which is placed in an orbit around the Earth and operates through commands from sent from the control center on Earth, such as Hubble space telescope, Herschel satellite, Infrared Astronom
ical Satellite (IRAS), Infrared Space Observatory (ISO), International Ultraviolet Explorer (IUE), Planck Satellite, Spitzer Space Telescope.

Space weather is the concept of changing environmental conditions in outer space. It is distinct from the concept of weather within a planetary atmosphere, and generally deals with the interactions of
ambient radiation and matter within interplanetary, and occasionally interstellar space. Space weather describes the conditions in space that affect Earth and its technological systems. Our space weather is a consequence of the behavior of the sun, the nature of Earth's magnetic field, and our location in the solar system.
The varying conditions in space and specifically in the near-Earth environment. Space weather is chiefly solar driven, resulting from solar activities such as solar flares, solar wind, and coronal mas
s ejections that affect magnetosphere, ionosphere, and thermosphere. Non-solar sources such as Galactic cosmic rays, meteoroids, and space debris can all be considered as altering space weather conditions at the Earth. Space weather may affect the performance and reliability of space-borne and ground-based technological systems and can endanger human life or health. The research in this field aims at monitoring and diagnosis of space weather conditions and constructing reliable numerical prediction models.
Space Weather is the physical and phenomenological state of natural space environments. The associated discipline aims, through observation, monitoring, analysis and modelling, at understanding and pr
edicting the state of the Sun, the interplanetary and planetary environments, and the solar and non-solar driven perturbations that affect them, and also at forecasting and nowcasting the potential impacts on biological and technological systems.
A time-limited condition of the space environment (e.g. Solar Flare, Solar energetic particle event, Substorm). Often this involves a propagating disturbance (e.g. CME or interplanetary shock).
