Maintenance of Telescope
Maintenance work of the telescope, such as exchange of secondary mirror and science instruments, is planned and conducted by engineers, and day crew from the telescope technology and instrument divisions. The maintenance work helps to maximize the telescope performance at night observations.

Development of Science Instruments
Science instruments, manufactured at the observatory and at institutes at home and abroad, are installed and tested at the telescope simulator for a final check of their operation when they are installed at the telescope. Not only hardware performance, but data transmission and operability are also tested, and are then carried to the telescope when accepted in the test.
In recent years, preparation is ongoing to install Prime Focus Spectroscopy (PFS), a groundbreaking instrument that can simultaneously obtain a large number of spectrums, ranging from optical to infrared light, from celestial objects that widely exists, utilizing as many as 2,400 optical fibers.

Release of Observation Results
Information is released via the web and social media to widely release observation results obtained from the Subaru Telescope.
Lectures at Hilo Base Facility

Lectures at Hilo Base Facility
Observatory staff offers interactive lectures and classes between the Hilo Base Facility and schools or science organizations in Japan and on the Big Island of Hawaii.
Outreach Activities in Hawaii

AstroDay
The observatories on Maunakea organizes an annual event called AstroDay to offer exhibitions and demonstrations at a venue of a shopping mall in Hilo.

Science Class for Children
Science classes are held on multiple occasions every year in the Hawaii Island, including the Science Day for remembrance of Astronaut Ellison Onizuka from the Hawaii Island. Observatory staff participates in these events to offer classes of craft, experiments, and observations for children, and hold exhibitions of the observatory.

School visit
Observatory staff visit schools to give classes upon teachers' request. Many researchers of the observatory take part in an event called the Journey through the Universe, where personnel of the Maunakea Observatories visit many schools for the week of this event.
Lectures
Observatory staff hold lectures of astronomy from time to time at places such as the University of Hawaii at Hilo, the Onizuka Center for International Astronomy Visitor Information Station, and the Imiloa Astronomy Center.
