Default ISS illuminated with green laser and viewed from ground



The ESA took some video from the ground of the ISS as they illuminated it with a 3.6W 532nm laser a week ago. Pretty cool stuff and an amazing video. They must have used some mighty fine adaptive optics to get images like that which would normally be impossible due to seeing limitations. Or it is possible that they used very high speed photography with a fast optical tube and then made the video using some kind of speckle imaging composite post processing technique.

Woah, that's pretty cool.
I wish I had a 3.6W green laser
Then again, probably too much power for me to be playing with at the moment.

They illuminated it with a green laser but the image is colored?

They were testing a laser communications system and happened to take some images at the same time. The primary light source reflecting off the ISS to make it visible is still the Sun by far, but there is was a slight green tint visible due to the laser.

Ah ok. Wish they could have flashed the laser on and off to make it easier to tell the difference. But then again they probably had more important tests to do.

Can we turn them in for lasing a spacecraft and collect the $10000 reward?

I have a 5 watt 532nm CW laser and I like the idea!

Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.
