Plaque citation summarizing the achievement and its significance:
The 2.2 meter (88 inch) telescope was the first advanced research telescope to be built near the summit of Mauna Kea, to take advantage of unequaled observing conditions found at high elevation on Hawaii. The site is above 40% of Earth's atmosphere and nearly 90% of water vapor. Located near the equator, it enables observation of almost of all the sky.
200-250 word abstract describing the significance of the technical achievement being proposed, the person(s) involved, historical context, humanitarian and social impact, as well as any possible controversies the advocate might need to review.
In 1964, Gov Burns of Hawaii, bulldozed a crude road to allow Gerard Kuiper, Director of Lunar and Planetary Laboratory, University of Arizona, access to the top of Puu Poliahu cinder cone on Mauna Kea for seeing tests. Kuiper concluded Mauna Kea was the best site in the world for ground-based astronomy. Due to the site elevation 13,796 feet (4,205 meters), it is above 40% of Earth's atmosphere and nearly 90% of atmospheric water vapor, which absorbs infrared wavelengths important for planetary surface characterization. Located near the equator, it enables observation of almost all the sky. Dedicated on June 26, 1970, the University of Hawaii 88-inch computer controlled, astronomical telescope became the world’s highest. Providing much useful data in support of the Apollo missions to the moon in the 1970s and planetary missions, as well as stellar and galactic observations. In 1992, the discovery of the Kuiper Belt, distant objects beyond Neptune, led to the demotion and declassification of Pluto as a planet. The platform was also used to develop new tools for telescopes that are now industry standard on telescopes around the world including the Mauna Kea Keck observatory completed in 1992. The 2020 Nobel Prize award acknowledged the prestigious Mauna Kea Keck facility pioneering discovery that our galaxy has at its center a supermassive black hole (Sagittarius A) led by Andrea Ghez of UCLA. Today, it is fully automated with robotic remote control from UH-Hilo.

In the late 1950’s the space race started between the United States and the Union of Soviet Socialist Republics, leading to a great increase in interest in geophysics and planetary exploration. The University of Hawaii (UH) received funding from the National Science Foundation in 1961 to establish the Hawaii Institute of Geophysics (HIG), and one of the projects of this new institute was to build a solar observatory near the summit of Haleakala on the island of Maui. Haleakala reaches 3055 meters elevation, and has a paved road enabling easy access to the peak. Gerard Kuiper, Director of the Lunar and Planetary Laboratory at the University of Arizona, came to Hawaii to investigate the suitability of high altitude sites for astronomical observatories, and visited the Haleakala site with his Native Hawaiian assistant, Alika Herring. Kuiper recognized the particular advantage of high altitude sites as being above a significant amount of the earth’s atmosphere and in particular, almost all of atmospheric water vapor, which strongly absorbs infrared radiation. They found conditions on Haleakala “excellent”, but subject to clouds and occasional fog. In the distance across the Alenuihaha Channel, they could see the summit of Mauna Kea on the Big Island of Hawai’I; at 4,207 meters, it stood above the clouds almost all the time. At the invitation of Mitsuo Akiyama of the Hawai’I Island Chamber of Commerce, Kuiper visited the Big Island in 1964, travelling to the end of the road at Hale Pohaku, at the 2800 m elevation; conditions seemed promising, but travel beyond Hale Pohaku was only possible on foot. Kuiper then met with Hawaii Governor John Burns, who agreed to fund a bulldozer to cut a dirt road to Pu’u Poliahu, a peak next to the summit. By April that road was finished, and a small concrete slab was poured to make up the foundation for a dome, in which a 12.5 inch reflecting telescope was placed. In June of 1964, Herring began measurements of atmospheric clarity, called “seeing”, and measurements of water content. Herring reported to Kuiper that on a scale of 0 (very poor) to 10 (perfect), many nights rated 9 or 10. At a dedication ceremony, Kuiper proclaimed “This mountaintop . . . is probably the best site in the world – I repeat – in the world, from which to study the Moon, the Planets, the Stars . . . It is a jewel! This is the place where the most advanced and powerful observations from this Earth can be made.” Kiuper proposed that NASA fund the relocation of a 28 inch telescope from the Lunar and Planetary Laboratory (LPL) to the top of Mauna Kea, which LPL would manage from their Tucson location. NASA administrators were concerned that LPL could be overextended, and solicited proposals from Hawaii and Harvard. At the time, the University of Hawaii didn’t have an astronomy department – just a few solar astronomers led by John Jeffries at HIG. Jefferies enlisted the president of UH, Thomas Hamilton to lobby the Hawaii State government, for the state to provide roughly 3 million dollars for infrastructure . Governor Burns was an enthusiastic supporter. This made the UH proposal very attractive, and on July 1, 1965, the contract was awarded.
What obstacles (technical, political, geographic) needed to be overcome?
The largest problem was dealing with the location. The original dirt road was lengthened by adding some switchbacks, but was still unpaved and steep in sections. Travel time from concrete plants on Hawaii Island was too long - concrete would begin to set up in the trucks – so a “batch plant” was set up below the summit cinder cone. Cement, sand, aggregate, and water were trucked up to the plant and mixed there, where it could be delivered to the construction site in a fraction of an hour.. The telescope itself was built by Boller and Chivens, a telescope manufacturer in Pasadena, California. Everything had to come up the long road to the summit site, and the telescope had to be designed for self-sufficiency. The observatory dome included a “horn” – and extension added near the top of the dome – that carried a crane, so the 88 inch mirror could be lifted out of the telescope and lowered into a wing of the building. There it could be placed in a large vacuum chamber, where aluminum vapor could be deposited on the mirror to renew the reflective surface, Workers had to acclimatize to the altitude at the summit, and lived in temporary building built at the end of the paved road at Hale Pohaku (Stone House) when not working. The telescope was the first to be controlled by computer, an IBM 1800.

Keck Observatory on Mauna Kea, Prof Ghez made the pioneering discovery that our galaxy has at its center a supermassive black hole known as Sagittarius A (A-Star). b. 27 year-long effort leading up to the discovery of A-Star earned her the Nobel Prize and she’s happy to share with Hawaii’s prestigious Mauna Kea facility (Keck). 3) Christoph’s e-mail dated 10-18-2022 showed current plaque on UH-88 site: NASA and NSF provided significant funding support for the UH-88 for Solar System Astronomy.
4) Partial transcript from John Jefferies interview 7-29-1977:
a. At the end of 1963, after a site visit to Haleakala which had many other installations and was crowded, Kuiper also visited Mauna Kea, which was inaccessible to motor transportation. He liked what he saw better than Haleakala and put up a site testing dome. b. In early 1964 after Gov Burns bulldoze a crude road to allow Kuiper access to the top of Puu Poliahu cinder cone, he installed a little U of AZ dome with a 10-12 inch telescope for seeing tests. Kuiper concluded Mauna Kea was the best site in the world for ground-based astronomy. c. In 1964 two groups, the Univ of Arizona and Harvard University had competing telescope proposal designs for NASA’s $3M grant. d. On July 1, 1965 UH announced an award of $3M contract to build the UH-88. e. The primary “trouble” was with the control system, programmer working on the IBM 1800. This was one of the first computer-controlled telescopes if you include the Defense Department instruments that were computer controlled at the time. Integrating a telescope drive mechanism with the IBM 1800 computer involving instrumentation, electronic control, and electronic data acquisition system. Also, UH-88 needed electronic engineering in-house. 5) Encyclopedia Britannica report updated 2-12-2024: “Mauna Kea Observatory”.
