sunshade

"As I slipped open the sunshade of my spacesuit, I could see that the sky above was black.

Though it’s better fabricated into a giant solar sail of a sunshade.

It's basically a honeycomb sunshade that, like the name says, minimizes reflections from the lens to make the shooter harder to spot.

The exception is anything involving sunlight - there the A7S2 runs into cooling issues without a sunshade.

They are not visible to the naked eye in their final orbits because they are farther away and they maintain an orientation that allows their sunshade to reflect sunlight away from Earth instead of toward it.

Amateur astronomers have reported that the sunshade appears to make the Starlink fainter than it would otherwise be.> But astronomers are still awaiting further confirmation that the modifications have a significant effect, says Meredith Rawls, an astronomer at the University of Washington in Seattle.

For instance to evaluate the possibility of building a space sunshade with a solar sail factory on a carbonaceous chondrite asteroid it would be reductionistic to design the system and mission in as much detail as possible, It is another to say that you need to make 10^14 kg of mylar and 10^12 kig of aluminum and make some broad guesses about stocks and flows from there.

>> The article covers the mitigations already in place and how they only partially resolve the issue.> So in April, SpaceX instead began launching Starlinks with a sunshade to block sunlight that would otherwise reflect off its antennas, which are the main source of the Starlinks’ brightness once they have reached their final positions.> So far, only one of these ‘VisorSat’ Starlinks has finished the journey to its final orbit of 550 kilometres above Earth.
