I think a large problem is going to be space debris - debris from previous launches and defunct satellites.
When the idea of an orbital power station was first formed in the early days of space exploration, space debris was not a problem. These days there is a huge number of tiny objects circling the Earth at high speeds - like bullets being shot at random.
The larger the orbital mirrors are, the more surface area there would be for collecting space debris.

Sure, you could place them in higher orbit, but then the mirrors would not get as much protection from solar wind from the Earth's magnetic field.

From what I have heard, the Samsung 840 is scandalously bad and most other types should fare better.

Right now, I would more interested in 48-layer MLC NAND from Toshiba than 32-layer TLC NAND if I can get it for the same price.

Samsung's TLC NAND in their "840 EVO" SSDs have had problems with performance dropping significantly after a couple of months of use. Samsung issued a "fix" with a firmware update, but after a couple of months more many users of the drives experienced choppy performance. Apparently the problem would be inherent in the TLC NAND that they use.

.. and I use to invoke nano in a terminal window by double-clicking an icon in the sidebar on my desktop.

You could also get them without backlighting if you go to WASD Keyboards directly.
Without backlighting you could get fully custom printing.
However, I have heard (said) that the WASD Keyboards' keyboards are louder than others in its class, so you may want sound dampening O-rings that also available from them.

If you are lucky, you may also find some left-over stock of Ducky G2 Pro with Cherry MX Clear. I have one, and I recommend them.
If you don't need the numeric keypad, a KUL ES-87 might also be a good choice.
BTW. all of the above support swapping Win/Command and Alt/Option if you use Mac.

I would also recommend the Logitech Illuminated Keyboard K800.

The type of scissor switches is branded "PerfectStroke", and they are also found in the (no longer made) Logitech DiNovo Edge.
These are my favourite scissor switches.

Whether Royal Kludge has mechanical switches or not is debatable.
The switches are copies of those of Topre, but with a different stem which accepts Cherry MX-compatible keycaps.

The switches of Royal Kludge (what a name...) and Topre are actually rubber dome switches but not the regular kind: they bottom out distinctly and the keys are sensed in a capacitative manner which has faster response time than most other keyboards.

I would say that the Topre Realforce line has the highest quality of any rubber dome keyboard, and not just for the switch type. The key action is very smooth and the materials and build quality is top notch. Enthusiasts who like them often liken the experience as "typing on a cloud of boobs" ...
If you can get old of one, I would suggest Topre Realforce with variable weighting (similar to the classic Key Tronic ErgoForce), and a Type S version for silencing also on the up-stroke.
These are really comfortable and silent, with a luxurious feel, but they are also pricey. Part of the price is because they are made in Japan.

NASA were if not the one, then one of the first who discovered the "hole" in the Ozone layer and raised alarm about it.
This discovery was a tremendously important piece of weather science. You can't argue with that.

I would say that "The Queen's English" is the reference.

French was the language of the French king and the region in which he lived, not of all of his subjects within France. There were many widely differing dialects all over France when the king formed the French Academy.

There has been some speculation that the name would have something to do with AMD. AMD has their own low(er)-level graphics API called Mantle, referring to the Earth's mantle. Vulkan is the work for volcano in some languages, and a volcano spews out magma from Earth's innards.

When Vulkan became public, AMD announced right then that they are stopping development on Mantle to focus on Vulkan.
It has been speculated that spurring the creation of Vulkan and the low-level API in DirectX 12 would have been AMDs intention with Mantle all along.

PowerVR is the #1 GPU on mobile phones and tablets. For instance, all Apple iPhones and iPads have had embedded PowerVR GPUs in their SoCs.

Imagination Technologies (PowerVR) posted this today with more in-depth info:

The purpose of Vulkan is apparently to be a low-level alternative to the high-level APIs OpenGL and OpenGL ES.
Game consoles such as the Playstation series have had both high-level and low-level graphics API:s for many years. Using the low-level API means that you can squeeze out more performance, perhaps at the expense of more developer time. The application takes over more duties, such as resource management etc.
If your app is a game, then your resource management and shaders are often pretty much static anyway.
