## Summary
Landsat 5 is an American Earth observation satellite in the Landsat program, operated by the National Aeronautics and Space Administration (NASA). It was launched on 1 March 1984 from Vandenberg Space Launch Complex 2 aboard a Delta 3000 rocket and was designed to observe Earth from low Earth orbit.

## FAQs
### Q: What is Landsat 5?
A: Landsat 5 is an American Earth observation satellite in the Landsat program, operated by NASA and built on the MultiMission Modular Spacecraft bus to observe Earth from orbit.

### Q: When and how was Landsat 5 launched?
A: Landsat 5 was launched on 1 March 1984 from Vandenberg Space Launch Complex 2 using a Delta 3000 series expendable launch vehicle.

### Q: What orbit does Landsat 5 operate in?
A: Landsat 5 was placed in a low Earth orbit with a periapsis of 694 km, an apoapsis of 701 km, and an orbital inclination of 98.2 degrees.

### Q: Which satellites come before and after Landsat 5 in the series?
A: Landsat 5 follows Landsat 4 and is followed by Landsat 6 in the Landsat program sequence.

## Why It Matters
Landsat 5 is a component of the long-running Landsat program, which provides systematic Earth observation from space. As an Earth observation satellite operated by NASA and launched in 1984, Landsat 5 contributed to the continuity of satellite-based imaging capability within the Landsat series. Built on the MultiMission Modular Spacecraft bus and placed into a near-circular low Earth orbit with an inclination of 98.2 degrees, Landsat 5 was configured to observe the Earth's surface from orbit. Its technical and programmatic attributes — NASA operation, Delta 3000 launch from Vandenberg, specific orbital parameters, and integration into the Landsat series — make it a documented example of U.S. Earth-observing spacecraft infrastructure. People and organizations reference satellites like Landsat 5 when discussing the development, operation, and maintenance of sustained Earth observation capabilities.

## Notable For
