Today Mercury is passing through inferior conjunction, passing between the Sun and the Earth. This fast moving planet will reappear above the dawn in about a week, rising towards maximum elongation on August 9th.
This is a modest apparition, with the planet reaching only 19° away from the Sun.
Among the claims made against the observatories this is probably another on the top three list… That TMT will be obsolete before it is complete, that the telescope is simply a waste of money.

This claim draws on the public perception that technology is advancing at a breakneck pace and that many devices we use in out daily lives are quickly obsolete in the face of new tech. What many people do not understand is that this does not apply to telescopes, or rather it does, but not in the way you might think.
The telescope itself is simply a light collector, a large mirror that collects the light from distant sources and focuses it for use by an instrument.
The basic optical design of one of the large telescopes atop Mauna Kea has not really changed that much since Laurent Cassegrain sketched it out in 1672. Sure the design has been refined, and made a bit bigger, but totally recognizable as the same in those original drawings from more than three centuries ago.
If the basic design of the telescope has served for centuries one can understand why it will not be obsolete in a few mere decades. The real technology in an observatory is found elsewhere.
Among the claims made against the observatories this is probably on the top three list… The observatories do not hire local people. As you can guess this is also quite wrong.

For those who do not work on the mountain it is easy to be skeptical of job claims. Too many think that you need to be an astronomer to work at an observatory, or need to have some advanced degree.
What so many folks do not realize is that observatories hire relatively few astronomers. Maintaining a large observatory is the job of a wide range of people, a few scientists and engineers, and a lot of skilled workers that get the job done.
Astronomers do not fix telescopes, guys who know what wrench to use fix telescopes. The summit crews are largely mechanics, technicians, welders, electricians, and similar. By and large these guys are local, with most having grown up in the islands.
When the Thirty Meter Telescope issue began I would have described myself as quite sympathetic to the cause of Native Hawaiians due to my normal political leanings and my own personal heritage. Over the years I have often become quite bitter about the continued use of lies, smears, and insults used against the telescopes by opponents.

Can we have an honest dialog here?
Apparently not. The issues has become something akin to a religious crusade among people who have devoted their lives to the cause. When this happens little things like truth seem to lose.
I am going to be blunt here, we know much of the anti-TMT argument is either false or gross exaggeration. Project supporters have patiently corrected these arguments time and time again, documented the issues during the hearings, and yet we continue to hear these false arguments repeated. They are repeated online in social media, in newspaper editorials, even under oath in official proceedings.
Certainly some people repeat this misinformation in an honest belief that it is true, maybe they hear it from a source they trust, perhaps from a leader in the protest movement. We are now well over a decade into the controversy and we have been over and over the issues so many times, those more involved with the controversy should know the difference.
This one is a new one, at least to me, this bit of misinformation started showing up just after Governor Ige’s press conference that announced the access road closure to allow construction equipment to be moved.

Why do I get the feeling shit will go down on Mauna Kea with TMT, which will give the authorities the excuse to execute their plan of shutting down the summit road to the public for good? Mountain access stolen…. (Isn’t that part of the new plan? Reducing public’s access? All they need is an excuse to do it sooner than later. What then?)
Having a good understanding of management to the mauna I know this one to be false. One need only read the Mauna Kea Comprehensive Management Plan, Public Access Subplan to know where the official stance on access is. These are the binding management plans for the mauna, and nowhere do these plans permit permanent restrictions on the public’s use of Mauna Kea. Quite the opposite, public and cultural access is to be specifically permitted.
Changing these plans, and changing the access rules requires a full rule making process and public hearings.
One of the most pervasive claims surrounding the summit is that there are obsolete and abandoned telescopes littering the summit region. The claim seems to be pushed to show that there is no need for a new telescope or that the university’s management of the summit is negligent.
The CalTech Submillimeter Observatory under the stars
There are currently thirteen telescope facilities. All of these telescopes are functional, or were usable scientific instruments prior to shutdown, none have been abandoned in any sense.
Two of the telescopes are currently shutdown, in many ways victims of the current controversy rather than obsolescence. Both could be brought back on-line to perform useful science if allowed.
The Caltech Submillimeter Observatory, or CSO, was shutdown and is now awaiting dismantling and site restoration. An environmental assessment and a conservation district use permit are in process to allow this to happen.
Even while CSO has been shut down the reasons were budgetary, not so much obsolescence. The telescope itself is planned to be dismantled, moved, and reassembled on another site elsewhere in the world.
The University of Hawaii Hoku Kea telescope was due to be recommissioned with a new telescope installed in the recently renovated dome. This is on hold due to the TMT issues and the dome is likely to be dismantled as part of the deal to allow TMT. Loss of this telescope is unfortunate as this was a student telescope for university astronomy students.
Given the actual status of these two shutdown telescopes it is clear they are not abandoned as per the usual claim. All of the other facilities on the summit are operational and doing science.
This lie is the favorite of the conspiracy theory crowd. It plays upon the fundamental distrust and enmity towards the US military that many segments of our island community hold. How can you have a giant structure on the mountain without the military being in charge? With lasers!

Why does TMT think #MaunaKea is worth all this trouble vs. the Canary Islands?
Is it the subtle cloud cover difference, or the FACT that Hawaii is heavily militarized with all 4 branches nearby?
Spoiler: major weapon contractors reside in current telescopes.
There is even a military base positioned to protect it! Never mind that base is a training base that has no troops more than half the time.
As someone on the inside I know this to be false. How to prove that? A bit more difficult as none of my answers are going to be heard by the true believers.
There are some practical considerations that should make this clear. The largest telescopes are not capable of tracking something as fast as a low earth orbit satellite, where the spy satellites operate. These big telescopes simply can not move fast enough to follow these objects across the sky. I work on the drive systems, I know.
While much of the island focused on events taking place on the slopes of Mauna Kea, we had a better plan for Monday evening… Take some activities, and a couple telescopes out to a local library and share the sky with anyone who came.

We planned to bring a presentation and activities to the Kohala library. While the gals presented inside we had a couple telescopes setup outside the front door for anyone to enjoy. Thus is was a team of four… Shelly, Kelleen, Scott, and myself that arrived at the library about 5pm.
The drive over the Kohala on the mountain road is often pretty in the late afternoon. This day was no exception, the afternoon lighting the rolling green hills, Haleakala on Maui looming directly ahead of me as I drove.
I do worry about setting up a star party in Kohala as the weather is notoriously fickle and heavy rain squalls can sweep off the ocean very quickly. I was greeted by nearly clear skies, a pleasant surprise that bode well for the evening.
This evening look for the Moon rising in the east just as the Sun sets in the west. Across the Big Island this can often lead to moonbows as the low elevation moonlight interacts with fog and clouds.
You see this claim bandied about routinely in newspaper comment sections and Facebook, It has several variations, from biggest, tallest, to largest, to most area. This has been repeated since the beginning of the controversy and continues to the present as a protester staple.

This particular myth is easily disproved as there are any number of buildings on the island that are much larger in several respects. All you need is some elementary school math.
