Astronomical Observatories

Hawaii is renowned for its collection of world-class astronomical observatories located on the summit of Mauna Kea, a dormant volcano on the Big Island. The high elevation, clear skies, and relatively remote location make it an excellent site for observing the cosmos. The observatories on Mauna Kea have contributed significantly to our understanding of the universe, and many of them are operated by international collaborations. 

  • W. M. Keck Observatory: The Keck Observatory comprises two identical 10-meter telescopes, making them among the largest optical and infrared telescopes in the world. The observatory is famous for its innovative use of segmented mirrors, adaptive optics, and cutting-edge instrumentation. It has been instrumental in a wide range of astronomical discoveries, including the study of distant galaxies, exoplanets, and more.
  • Subaru Telescope: Operated by the National Astronomical Observatory of Japan, the Subaru Telescope features a massive 8.2-meter primary mirror and specializes in infrared and optical observations. It has played a significant role in various fields, such as studying the formation and evolution of galaxies, as well as detecting and characterizing exoplanets.
  • Gemini Observatory: The twin Gemini telescopes are part of an international collaboration involving multiple countries. These 8.1-meter telescopes are equipped with advanced adaptive optics systems, enabling astronomers to achieve high-resolution imaging and spectroscopy. The Gemini Observatory contributes to a wide range of astronomical research, including planetary studies, star formation, and the exploration of distant galaxies.
  • Canada-France-Hawaii Telescope (CFHT): This 3.6-meter telescope is a partnership between Canada, France, and the University of Hawaii. The CFHT focuses on a broad range of astronomical investigations, including studies of dark matter, the nature of distant galaxies, and the characteristics of asteroids and comets.
  • James Clerk Maxwell Telescope (JCMT): Although originally established for submillimeter astronomy, the JCMT has contributed to space exploration by observing the universe in the submillimeter and far-infrared wavelengths. It has been used to study star formation, galaxy evolution, and the interstellar medium.

These observatories are equipped with state-of-the-art instrumentation and technology that allow scientists to probe the universe across various wavelengths, from visible light to radio waves. They have been responsible for numerous groundbreaking discoveries and have greatly expanded our knowledge of cosmology, astrophysics, and planetary science.

It's important to note that while these observatories have greatly advanced our understanding of the universe, there have also been concerns about their impact on the natural environment and cultural significance of Mauna Kea to the Native Hawaiian people. These concerns have led to debates and discussions regarding the balance between scientific research and cultural preservation.

Planetary Analog Environments

Hawaii offers a diverse range of geological and environmental features that make it an attractive location for studying planetary analog environments. Several sites on the islands share characteristics with other celestial bodies, allowing scientists to conduct research and tests relevant to space exploration. 

Planetary Analog Environments


  • Volcanic Terrains: Hawaii's volcanic landscapes, especially on the Big Island, provide analogs for the surfaces of planets like Mars and moons like Io. The extensive lava fields, volcanic craters, and other geological features offer insights into processes like volcanic activity, erosion, and the formation of various geological formations. Mauna Loa and Kilauea are particularly interesting for studying lava flows and their associated features.
  • Lava Tubes: Lava tubes are natural underground tunnels formed by flowing lava. They offer analogs for potential habitats on the Moon and Mars. The Hawaii Space Exploration Analog and Simulation (HI-SEAS) project, for instance, has used lava tube environments on the Big Island to simulate long-duration space missions, testing factors such as isolation, confinement, and resource utilization.
  • High-Altitude Sites: Hawaii's high-altitude sites, like the summit of Mauna Kea, share similarities with the low-pressure environments of other celestial bodies. Researchers can use these locations to test equipment, study how materials degrade under low atmospheric pressure, and develop strategies for future missions.
  • Underwater Environments: While not exclusively a Hawaiian feature, the state's coastal waters offer insights into the challenges of undersea exploration, relevant to future missions to ice-covered moons like Europa. Underwater habitats and analogs provide opportunities to test technologies and practice operational procedures.
  • Microbial Communities: Hawaii's volcanic soils and unique ecosystems host extremophiles—microorganisms that thrive in extreme conditions. Studying these microbes can help scientists understand the potential for life on other planets with similar harsh environments.
  • Arid Regions: Some parts of Hawaii, particularly on the leeward sides of the islands, experience arid conditions. These areas can serve as analogs for deserts on Mars and other planets, where rovers and landers have been deployed to explore the surface.
  • Coral Reefs: While not directly related to planetary surfaces, studying coral reefs in Hawaii can provide insights into the diversity of ecosystems and the potential for life in extreme and challenging conditions. This knowledge could have implications for the study of life on other planets.

It's important to note that while Hawaii offers valuable analog environments, there are also ethical and environmental considerations associated with conducting research in these areas. Respect for local ecosystems, cultural sensitivity, and environmental preservation are crucial when conducting studies in Hawaii or any other analog environment.

Overall, Hawaii's diverse range of geological features, from its volcanic terrains to underwater ecosystems, provides a unique opportunity for scientists to study and simulate conditions relevant to space exploration and gain insights into the challenges and possibilities of exploring other celestial bodies.

Small Satellite Launches

Hawaii had been exploring the possibility of becoming a launch site for small satellites, also known as CubeSats or smallsats. Small satellite launches have gained popularity in recent years due to their cost-effectiveness and ability to carry out a variety of missions, such as scientific research, Earth observation, technology demonstration, and educational projects.

Small Satellite Launches


  • PacStar: One of the initiatives related to small satellite launches in Hawaii was the PacStar project. The University of Hawaii's Hawaii Space Flight Laboratory (HSFL) was involved in developing the PacStar launch system, which aimed to provide a cost-effective and flexible platform for launching small satellites into space. This project was intended to enable educational institutions, research organizations, and commercial entities to access space for various purposes.
  • LauncherOne Flight: Virgin Orbit's LauncherOne, a small satellite launch vehicle, completed a successful launch from the Mojave Air and Space Port in California in January 2021. While this launch wasn't directly from Hawaii, it demonstrated the potential for mobile launch platforms to reach a variety of orbits. Virgin Orbit had previously mentioned Hawaii as a possible future launch location due to its strategic location for specific orbital inclinations.
  • Geographical Advantages: Hawaii's geographical location in the middle of the Pacific Ocean provides certain advantages for launching satellites into specific orbits. Launching from Hawaii can offer a wider range of orbital inclinations compared to launches from continental launch sites, which can be useful for satellite constellations and missions requiring unique orbits.
  • Environmental and Regulatory Factors: Establishing a launch site involves considerations related to environmental impact assessments, safety regulations, local community engagement, and potential disruptions to existing industries and ecosystems. These factors need to be addressed carefully when considering a new launch site.

It's worth noting that while there have been discussions and initiatives related to small satellite launches in Hawaii, these plans could be influenced by a range of factors, including regulatory approvals, funding, and the overall evolution of the small satellite launch industry.
