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 ...
Polar orbit: An orbit that passes above or nearly above both poles of the planet on each revolution. Therefore, it has an inclination of (or very close to) either 90 degrees or −90 degrees. Polar Sun-synchronous orbit (SSO): A nearly polar orbit that passes the equator at the same local solar time on every pass.
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.

The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring.
A geostationary orbit, as viewed from above the North Pole. A satellite whose orbital period is an integer fraction of a day (e.g., 24 hours, 12 hours, 8 hours, etc.) will follow roughly the same ground track every day.

A non-Sun-synchronous orbit (magenta) is also shown for reference. Dates are shown in white: day/month. A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, [1] is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time.
Fram2 is a planned private human spaceflight mission, operated by SpaceX on behalf of entrepreneur Chun Wang.During the mission, the 16th crewed orbital flight of a Crew Dragon spacecraft, Wang and his all-civilian crew — Jannicke Mikkelsen, Eric Philips and Rabea Rogge — will be propelled into a polar orbit, a first for a human spaceflight mission.
