ISS celebrates 15 years of service




Today's APOD page shows a nice video how the International Space Station initially has been assembled using three modules docking together between November 1998 and July 2000. From then on module by module and solar panel by solar panel have been added and re-arranged, to grow the ISS to the size of a football field.
The nice thing about outer space is: there is plenty of space Wink .

Fantastic! Had not looked at APOD yet today.

Great photo!

Was just thinking plenty of space probably becomes even more meaningful when one considers that human beings are steadily running out of space on earth. Wink

True, deanhills, but considering how much energy, money and effort we had to invest to build and operate this relatively small space for just a few scientist in our orbit it becomes unimaginable to achieve this for billions of human beings.

Thus I sould have added to my blog posting:
"The bad thing about outer space is: it is not as convenient to acquire as the green hills and meadows down there on Earth."

Well said! Would be interesting if somewhere in the generations ahead of us they discover that it has been much more convenient than we thought. Teleporting becomes effortless and real through a new discovery. And the generations we had spent on earth become to be known as the very dark ages. Through teleporting and crossing over time and space we finally realize how beautiful it can be for real.

Resources would be an issues unless you take those from the rocks out there but you still need to process, refine and create, cut and fashion on those pieces. Could you imaging trying to build stations like that? If it's taken this long to build a fairly simple station? I can't picture it. The costs seem too high.

Nevertheless, lawyer and politicians in US already take this seriously.
The US Congress has approved a draft of a law allowing US citizens to explore and dig resources in outer space: H.R.2262 - SPACE Act of 2015.
And there already exists an Asteroid Mining Company: "Planetary Resources".

Iridium is a resource we might be motivated to get from asteroids. It is a metal needed to produce OLEDs and it is very rare on Earth.
Iridium originally was available on Earth but because of its high density it traveled towards the center of the Earth when the surface still was not solid - long time ago - so that nowadays it is impossible to mine. More Iridium arrived on Earth through meteorites, we find it in impact areas, especially at the Gulf Of Mexico where that large one hit our planet 66 million years ago which most likely killed most life on Earth including most dinosaurs. This amount of iridium is not high and will be consumed soon if we start mass production of OLED.
Thus, here really is one big motivator to get out into space to mine iridium on asteroids.
