Hubble Space Telescope
An observatory above the atmosphere, and a satellite you can follow around Earth. Hubble connects the science of distant galaxies with the very practical question of where a spacecraft is right now.
Satellite mission guides
Meet a telescope, an Earth-observation mission and a pioneer from the beginning of the Space Age. These featured guides connect mission history and useful facts with the spacecraft you can follow in the tracker.
Landsat 9
A view of Earth's changing landscapes. Landsat 9 turns repeated observations of the same places into a record that helps people understand changes in land and water.
Vanguard 1
A small spacecraft with a long history. Vanguard 1 offers a way to connect the first years of the Space Age with an object that is still represented in today's orbital catalogue.
Read about the mission. Follow the orbit.
These are a small selection of detailed guides. The live tracker contains many more objects: use its search box for a name or NORAD catalogue number, and Filters to explore different constellations and orbit types.
Mission facts and orbital predictions answer different questions. The guides explain what a spacecraft was built to do. The tracker uses published orbital elements to predict where it is, with upcoming passes calculated for a location you choose. Neither is a live camera feed.
