No Billboards in Space
An anonymous reader writes "CNN is reporting that the Federal Aviation Administration proposed Thursday to amend its regulations to ensure that it can enforce a law that prohibits 'obtrusive' advertising in zero gravity." From the article: "For instance, outsized billboards deployed by a space company into low Earth orbit could appear as large as the moon and be seen without a telescope, the FAA said. Big and bright advertisements might hinder astronomers."
I'm a member of the astronomy club here in Orlando and Disney World about 35 miles away impedes our observations. Any astronomer will tell you that a full moon can ruin observations for the night and any billboard that's as bright as the moon and is in full brightness all the time is going to tick every astronomer off within the viewable region. I feel sorry for any country's astronomers where one of these things get put up.

Likewise, a lot of satellites never pass directly over US soil, but could still appear as large as the Moon to Americans.
That's virtually impossible. If my math is right, an advertisement in geosynchronous orbit would have to be about 325km accross in order to be the same size as the moon. Since it'd have to be at least semi-ridged (and assuming it was square), the cost of building a sign with a surface area of 105625 square kilometers would be enormous.
If that were true, the Soviet Union would not have been able to fly over U.S. territory and vice-versa. It was a deliberate choice Eisenhower made in 1955 when he proposed his "Open Skies" initiative. When Sputnik flew a few years later, he didn't complain about its flying over US territory because he wanted the right to do the same thing. In 1960 when Corona flew, it made a hash of the fear that the Soviets had an advantage over us and enabled Eisenhower to focus on domestic issues instead of meeting a non-existant military threat.
Outer space is open to whomever can get there.
