Test ranges, observatories and ground stations are a hand-picked list kept in this project rather than a published catalogue: no catalogue answers which of the world's thousands of observing sites belong on a map of it. The article below is what lets the choice be argued with.

## What it is

The Maunakea Observatories (MKO, also known as Mauna Kea Observatories) are a group of independent astronomical research facilities and large telescope observatories that are located at the summit of Mauna Kea on Hawaiʻi, United States. The facilities are located in a 525-acre (212 ha) special land use zone known as the "Astronomy Precinct", which is located within the 11,228-acre (4,544 ha) Mauna Kea Science Reserve.
