  1. International Space Station - Assembled over the last two decades, this football field-sized structure orbits in LEO, hosting international astronauts conducting microgravity experiments.
  2. Hubble Space Telescope - The legendary Hubble orbits in LEO, sending back astonishing deep space images that have revolutionized astronomy.
  3. GPS Satellites - The 31 GPS satellites in medium Earth orbit provide positioning, navigation, and timing data to billions of users worldwide.
  4. Iridium Satellites - The 66 satellites of the Iridium constellation in low Earth orbit enable global satellite phone connectivity from pole to pole. Iridium Satellites
  5. GOES Satellites - These advanced weather satellites in geostationary orbit have monitored Western Hemisphere weather since the 1970s, tracking storms and improving forecasts.
  6. TDRS Satellites - The Tracking and Data Relay Satellite network in geostationary orbit provides constant communication links between Earth and spacecraft like the ISS.
  7. Sirius FM Satellites - In elliptical geosynchronous orbit, these radio satellites broadcast Sirius XM’s commercial-free music to millions of subscribers across North America.
  8. Planet Labs Satellites - Planet operates a fleet of small Earth observation satellites in low Sun-synchronous orbits, imaging all of Earth’s landmass daily. Flock Satellites
  9. INMARSAT Satellites - Located in geostationary orbit over the equator, these communications satellites provide mobile and emergency services to ships, planes and handheld devices.
  10. Tianlian Satellites - China’s six Tianlian data relay satellites in geostationary orbit transmit commands and data between the ground and China’s manned spacecraft.

These 10 modern satellite systems showcase cutting-edge space technology with real-world impacts. Their capabilities for observation, communication, navigation and more continue the iconic satellite legacy stretching back to humanity’s earliest space achievements.
