It's a view we rarely get to see.

Here's a rare close-up look at an active satellite in orbit.

Maxar Technologies' Worldview-3 satellite has delivered images of NASA's Landsat 8 spacecraft from ranges of between 56 miles (91.4 kilometers) and 80 miles (129.9 km), showing clear details of the powerful Earth-observation satellite.

A still image reveals the 29.5-by-1.3 foot (9 by 0.4 meters) solar array powering Landsat 8, as well as distinct science payloads on the satellite's 9.8-foot-long (3 m) bus, or main body.

Both satellites are in similar, near-polar orbits, with Worldview-3 circling around 381 miles (613 km) above Earth, while Landsat has a higher altitude of 437 miles (703 km).

The images also hint at how satellite imagery can be used for potentially checking out the health or causes of issues for satellites. They can also be used for improving countries' space domain awareness and checking out satellites launched by other space powers.

The U.S., Russia and China are thought to have space situational awareness or inspector satellites in geostationary orbit, where satellites can more easily adjust orbits to get relatively close up to other spacecraft.
