Well, air space and outer space limits are not clearly defined in international law. Geostationary orbit is far away but a country could try to include it in its own air space. Of course none of these countries are superpowers (even if some like Brazil or India are pretty big) and could hardly enforce such rocambolesque pretention.That would violate several space treaties and piss off all the major powers of the Earth so I don't think that will come to pass. The area of international space law does need fresh thinking and new treaties to keep up with commercial and military developments but I don't see any way that equatorial countries can claim any air rites over the geostationary arc.
I think space is clearly defined as anything about 100 km and there is a ton of law/precedent for how the countries on the ground below have no control over what flies over except that they can restrict the satellites ability to broadcast over their territory. There is a lot of outer space law that has not been explored/tested/regulated, but control over the actual space itself is not really disputed. There are very clear procedures for companies to buy slots and broadcast from them; it's not like the wild west where everyone is grabbing space without regards to who is already there.Well, air space and outer space limits are not clearly defined in international law.
Nope. Not at all.i think space is clearly defined as anything about 100 km

The astronauts and cosmonauts on board the International Space Station have brought with them a host of bacteria from Earth. How do they keep them from creating havoc?
By 1998, after 12 years in orbit, Russian space station Mir was showing its age. Power cuts were frequent, the computers unreliable and the climate control system was leaking. But when the crew began a study to assess the types of microbes they were sharing their living space with, even they were surprised at what they found.
Opening an inspection panel, they discovered several globules of murky water – each around the size of a football. Later analysis revealed the water was teeming with bacteria, fungi and mites. Even more concerning were the colonies of organisms attacking the rubberised seals around the space station windows and the acid-excreting bugs slowly eating the electrical cabling.
When each Mir module launched from Earth it was near-pristine, assembled in clean rooms by engineers wearing masks and protective clothing. All the unwanted life now living on the station had been carried into orbit by the multinational group of men and women who subsequently occupied the orbiting laboratory.

Ceres' Bright Spots Come Back Into View
So the bright spots are back and they still don't know what they are. Fun times.
They are the remains of salt water geysers! There are at least pockets of water under Ceres ...
Harbinger of death.If Atlas manages to remain intact, some in the field have suggested it could grow from magnitude +1 to possibly -5
SpaceX is reporting a 50% reduction in the brightness of their communications satellites. They are experimenting with different coatings to reduce the glare from the satellites that can disrupt astronomical observations. The astronomers need a 10-20 fold decrease though, so 50% is good but not good enough.
The astronomers need to put together a database of all the professional and semi-professional observatories on Earth. This can be tied into an algorithm that causes the satellites to tilt their arrays away from the sun while passing over these zones. That would likely get them the rest of the reduction they need and they can likely survive the power hit just fine though there may be some problematic areas where they have to sun-seek regardless. They can work out an algorithm to stagger sun-seeking over those areas problem areas to help minimize the disruptions too.
This won't be easy but it's probably easier than further hardware revisions.
