WASHINGTON — Astronomers are calling on nations to ban advertising in space that can be seen from the ground, calling it the latest threat to the dark and quiet sky.

At a briefing during the 245th Meeting of the American Astronomical Society earlier this month, the organization rolled out a statement calling for bans on “obtrusive space advertising” because of the interference it could cause for groundbased astronomy.

Obtrusive space advertising is defined in U.S. federal law as “advertising in outer space that is capable of being recognized by a human being on the surface of the Earth without the aid of a telescope or other technological device.” Such advertising is banned in federal law through prohibitions on granting launch licenses for missions carrying payloads to carry out space advertising.
