    A bright artificial satellite flare is visible above the Very Large Telescope.Satellite constellations could have an impact on ground-based astronomy. [1]Satellites in medium Earth orbit (MEO) and low Earth orbit (LEO) are often deployed in satellite constellations, because the coverage area provided by a single satellite only covers a small area that moves as the satellite travels at the high ...

  9. Earth observation - Wikipedia

    en.wikipedia.org/wiki/Earth_observation

    Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. [1] It can be performed via remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example).
