Onizuka Center for International Astronomy

The Onizuka Center sits at 2,830 meters elevation on Mauna Kea's slopes and serves as a support facility for the astronomical observatories at the summit. The complex includes dormitories, common areas, and administrative buildings for daily research operations.

The center evolved from simple cabins built in the 1930s and received its current name in 1986 to honor astronaut Ellison Onizuka after the Challenger disaster. This naming marked recognition of scientific collaboration and safety culture in space research.

The center connects research with public interest through its visitor area and regular stargazing programs. Visitors can learn about the astronomical work happening on the mountain and engage with ongoing projects.

Visitors can acclimatize gradually by arriving at the center first and taking time to adjust before going higher. It is important to drink plenty of water and rest well before heading to the summit to avoid altitude sickness.

The facility operates separate areas for day and night shifts to support both construction workers and astronomers working at different times. This organizational division enables smooth operations even when people with completely different schedules work at the site simultaneously.
