This evening was the local hearing for the proposed Mauna Kea Public Access Rules. As the hearing took place at Waikoloa School I had no excuse not to go, it is practically at the end of our street. Of course I was going to attend even if I had to drive across island, this is an issue that directly affects me.
And yes, I testified, attempting to summarize my three pages of written testimony in three minutes. I suspect I got the gist across in a clear fashion, I will submit my written testimony as well.
Other than myself the testifiers were completely drawn from the anti-telescope community. It is unfortunate that the issue has become so polarized that no other members of the community attended. Access to the mauna affects more than just the astronomy and anti-astronomy folks, this should be of interest to anyone who calls the island home.
As such many of the testifiers paid scant attention to the contents of the rules, instead of providing constructive input so much testimony was simply another protest against the Thirty Meter Telescope. Some form of rules need to be put in place with or without the new telescope.
It is now round three for the Mauna Kea public access rules. The first versions of the rules were simply bad and rightly faced unanimous criticism from the community. Virtually nobody testified in support of the first version at the public meetings.
This latest version of the rules is much better, at least someone properly edited the rules and there are no complete blunders in the language.
There are still some items in the rules that are problematic. In general the university is attempting to regulate public activity on the mauna far beyond their mandate in the lease or in the comprehensive management plan.
There will be protests, that much is clear. Beyond that certainty there is no certainty. When? How big? How long? We just do not know, it is likely no one does.
As we prepare for the restart of construction of the Thirty Meter Telescope, those of us whose lives revolve around the mauna can only guess and prepare best we can.
While there is news of plans at the state and county level to deal with the protests, there is little information on the details in those plans. Both sides are keeping their cards close. We are given to understand that the county will be the lead agency it is clear that there will be state support.
Two earthquakes of the same magnitude strike our island a month apart. Two events that are quite interesting to us at the observatory. Both about the same magnitude, both occurring deep in the island, one was far more forceful at the telescopes causing some minor damage, the second caused no damage that we have found despite a thorough inspection.
Any strong earthquake is a concern for the telescopes. We need to know immediately just how strong the quake was, how much potential for damage occurred.
The telescopes are precision instruments with many delicate parts. On the other hand earthquakes are common on this volcanic island and we have learned how to deal with the shaking.
When attempting to measure the possible damage to the telescope it is not earthquake magnitude that is interesting. Rather we want to know the peak ground accelerations that occur at the summit facility. The actual forces that could potentially cause damage. These are measured by means of a logging accelerometer mounted in the basement of the observatory.
One of the questions that comes up often enough is what do the pictures look like? And that question is followed by… Where can I see them.
The problem… Science data is usually pretty ugly.
Keep in mind that the astronomers are often pushing the telescopes and instruments right to the limit. This means that the data is barely there, a trickle of photons that have come from unimaginably distant sources.
I have been in the observing room as the data comes in. I have watched over the telescope operator’s shoulder. It is strange to see folks so excited over a smudge.
Some equipment around the observatory is thirty or more years old. As you would expect, keeping it running can be a challenge.
There are two ways of dealing with this old equipment… Replacing it with something new is the preferred way. When it becomes difficult to locate spare parts, when it breaks down too often, just replace it with new gear. For much of the equipment this is the usual answer and is often a major part of the job.
Some equipment is not so easily replaced. When replacement would require wholesale redesign of a system it becomes more of a challenge. Sometimes the only choice is to keep that old gear running.
This is the case with our servo amplifiers. Twelve amplifiers supply the power that drives the telescope, one amplifier for each motor. Eight amplifiers and motors drive azimuth, four drive elevation. Three hundred and seventy tons moved by twelve relatively small DC motors. While much of the telescope control system was recently replaced, it was decided to keep the old servo amplifiers.
You might notice that these servo amplifiers are just a wee bit critical.
It is odd working at a place that everyone wants to visit. To be expected working at the world’s best observatory, after a dozen years the novelty of the situation has never grown old.
I enjoy leading a tour through the building. Doing a tour gives me a chance to vicariously see the facility through my audience’s eyes, seeing this special place afresh, to renew the fascination and wonder.
I think I am a fairly good tour guide, everyone says so, they might be right. Certainly after a decade of tours I have heard most of the questions and have ready and well rehearsed answers.
Inside tours of Keck Observatory are currently only available two ways… Know someone who works at the observatory, or take one of the monthly Kama‘āina Observatory Experience tours offered through ‘Imiloa and supported by all of the Mauna Kea observatories.
The KOE tour is free, but open to Hawaii residents only, you have to have a Hawaii ID to go. Each month the tours visit two observatories, rotating through the various observatories on the summit. The tours are also immensely popular, filling up very quickly.
This coming Saturday the KOE tours will visit the James Clerk Maxwell Telescope and the W. M. Keck Observatory. If you are on one of the morning tours, yes, I will be there, leading a tour through our facility.
This last week we said goodbye to a truly pioneering space telescope. The Kepler mission was designed to find exoplanets, planets that orbit around other stars. The mission succeeded beyond everyone’s expectations.
This little space telescope monitored over 500,000 stars during it’s mission, watching for the minuscule dip in brightness as a panet passed in front of the star. For nine years Kepler stared at those thousands of stars, during that time it discovered over 2,600 exoplanets. Along with the planets came a long list of other discoveries such as binary stars, variable stars, and novae.
After nine productive years this engine of discovery has come to an end. With the spacecraft out of fuel NASA flight engineers sent the last commands, shutting the spacecraft down.
The Keck Observatory and the Kepler Spacecraft had a great partnership. It was not possible to confirm most Kepler’s possible exoplanets using only data from the spacecraft. A large telescope using a high resolution spectrograph, like HIRES on Keck 1, would allow astronomers to not only confirm Kepler’s discovery, but to learn more about each exoplanet.
Mid-morning the awaited news found me… The Hawaii State Supreme Court has upheld the conservation district use permit for the Thirty Meter Telescope on Mauna Kea.
We had been waiting for this decision for some time. Based on the usual length of time the court takes to decide a case the decision should have appeared well over a month ago.
To no one’s surprise, the court took a little longer with this particular case. A case fraught with many questions that are hotly debated in this state.
The news quickly fueled a firestorm of mainstream media articles across the country and social media postings. The pro-telescope communities I participate in were celebrating. Opponents were decrying the decision with responses that range from disbelief to inflammatory.
Mid-afternoon found me atop the Keck 2 dome to check on some instrumentation. From there I had a perfect vantage point to look down upon the TMT site on the north plateau. I stopped to consider what those few acres of rock below had cost so far in terms of time and passion.
The ongoing collapse of the summit caldera on Kilauea has been generating a daily five point something earthquake. While not powerful enough to damage the facility, these events do show up in the data each night, bumping the telescope, disturbing the tracking, and occasionally ruining an exposure.
