  2. Polar (satellite) - Wikipedia

    en.wikipedia.org/wiki/Polar_(satellite)

    The Global Geospace Science (GGS) Polar satellite was a NASA science spacecraft designed to study the polar magnetosphere and aurorae. It was launched into orbit in February 1996, and continued operations until the program was terminated in April 2008. The spacecraft remains in orbit, though it is now inactive. Polar is the sister ship to GGS Wind.

  3. Polar orbit - Wikipedia

    en.wikipedia.org/wiki/Polar_orbit

    Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. [2] The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a Sun-synchronous orbit, where each successive orbital pass occurs at the same local time of ...

    The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting. [1]

    NOAA-21, designated JPSS-2 prior to launch, [2] is the second satellite in National Oceanic and Atmospheric Administration (NOAA)'s latest series of U.S. polar-orbiting, non-geosynchronous, environmental satellites, known as the Joint Polar Satellite System (JPSS).

  7. NPOESS - Wikipedia

    en.wikipedia.org/wiki/NPOESS

    The NOAA/NASA portion is called the Joint Polar Satellite System (JPSS). The first satellite in the program – originally called JPSS-1, but now known as NOAA-20 – was constructed by Ball Aerospace & Technologies Corp. , under a fixed price contract of $248 million with a performance period through Feb. 1, 2015. [ 8 ]

    en.wikipedia.org/wiki/Joint_Polar_Satellite_System

    The Suomi National Polar-orbiting Partnership , previously known as the National Polar-orbiting Operational Environmental Satellite System Preparatory Project and NPP-Bridge, has a nearly identical design as NOAA-20 and shares some ground systems with it but it was not designed as a part of JPSS. It was originally proposed as a proof-of-concept ...

  9. Biosatellite - Wikipedia

    en.wikipedia.org/wiki/Biosatellite

    A bio satellite is an artificial satellite designed to carry plants or animals in outer space. They are used to research the effects of space (cosmic radiation, weightlessness, etc.) on biological matter while in orbit around a celestial body. The first satellite carrying an animal (a dog, "Laika") was Soviet Sputnik 2 on November 3
