Space advertising is the practice of advertising in space. This is usually done with product placements during crewed space missions.
Space advertising falls into two categories: obtrusive and non-obtrusive.
Obtrusive space advertising is advertising in outer space that is visible to individuals on the Earth's surface without the aid of a telescope or other technological devices.[1][2] Both international and national laws govern the practice of obtrusive space advertising due to concerns about space debris (objects in space that can cause harm) and the potential obstruction of astronomical views from the Earth's surface. Contemporary regulations and technological capabilities limit space advertising, yet it persists in popular culture in a variety of forms.
Non-obtrusive space advertising is the term for any other type of advertisement in space, such as logos on space suits, satellites, and rockets.[1]
