Re: SpaceX Heavy Rocket Launch in FL Today!
Tesla was other-worldly in his genius. Whether he was an actual alien or not, well, it's fun to speculate but we'll never know. I only brought up Edison as an example that many inventors tend to be arseholes.
Nobody, really. The positions and orbits of satellites are known, so they can be worked around. I'm pretty sure launch sites are in controlled airspace, so there shouldn't be any air traffic to worry about. Once you get out of the atmosphere you're all good.

I know NORAD tracks something like 25,000 objects whizzing about.
There has to be some body managing it. Otherwise, what's to stop you and I putting up two satellites in the same orbit and then they smash into each other at 17,500mph (that was the Space Shuttles orbital speed), and then send debris whizzing into other satellites and causing a chain reaction, thereb y imprisoning us on our planet.

Re: SpaceX Heavy Rocket Launch in FL Today!
In my science class at middle school, Mr Howell attached a vacuum pump to a rectangular oil can. As he reduced the pressure inside the can, it got squashed.
He tried to give me all this mularkey about air pressure squashing the can, but I know it was the vacuum sucking it flat. It's science, mate. I seen it with my own eyes.
We have a Dyson DC41 and it stopped working. The vacuum leaked out. It's somewhere in the house, probably behind the couch. We had to get a replacement put in from the vacuum cleaner repair store.

I know it re: Edison. I was just holding forth and expounding on the absolute genius that was Tesla.

Yes they do. I know the science.

Re: SpaceX Heavy Rocket Launch in FL Today!
I found this. Hopefully doesn't break rule 7 or whatever it is.
Geostationary slots are a rare resource and are assigned to countries by the ITU (International Telecommunications Union) since they are mainly used for communications and broadcasting, and need deconfliction both in frequency allocation (to reduce interference - the main raison d'être of ITU-R as a division of the ITU) and in collision avoidance (tighter orbital boxes are costly in terms of lifetime xenon expenditure).
Almost everything else in orbit selection is based on the operator's discretion, provided the downlink and uplink frequencies do not conflict with other satellite, fixed and mobile services.
Orbits are checked through national space control centers, though, to avoid crossing paths with other satellites and space debris.
For more information on Geostationary services, please have a look at http://www.itu.int/ITU-R/space/snl/
EDIT: On sanctions and reprisals: violating an international treaty is bad since the culprits will find themselves shunned. States do have the ability and legal authority to jam or disrupt non-authorized transmitters that broadcast into their territories, so it shouldn't be surprising to the perpetrator to find his downlinks or uplinks jammed. It should be noted that GSO is far away from the Earth, and the link budgets are quite slim, so any modest interference will degrade the link beyond usefulness.
TL;DR - A non-state actor (a corporation) will be held liable by its national telecommunications (and space) authorities, while a non-compliant state will be unable to effectively use the slot in GEO due to easy counter-measures.

Re: SpaceX Heavy Rocket Launch in FL Today!
Personally I think that a trip to Mars is likely suicidal, and that we are a number of decades away from having reliable technology that makes sending men to Mars even vaguely reasonable. By which I mean that until we have a permanently manned base on the moon, with rockets going back and forth to earth at least a couple of times a week, then a trip to Mars is just too much of a gamble with potentially unreliable technology. Because if you experience a problem on, or on your way to Mars, you are going to be seriously screwed with respect to any sort of rescue.

Re: SpaceX Heavy Rocket Launch in FL Today!
FYI - POTUS is a highly scientific term for an obscure and dangerous type of space matter that has infected our planet. I was hoping that we could offload this toxic invader into the cosmos. It has nothing to do with politics, this is a public health issue. I'm surprised you didn't know that.

Of course, that's for satellites or objects entering Earth orbit. Since the roadster was destined for points beyond, all they had to do was wait for a window to launch and it's off to the asteroid belt.
