Summary: NASA's historic landing of a mobile rover on the surface of Mars created many newsworthy moments. Unfortunately, it also generated some embarrassing takedowns of NASA's own footage by YouTube's copyright flagging system, ContentID.

NASA uploaded its own footage of the landing -- footage that was public domain given that it was a work created by the U.S. government. US copyright law says that any work created by the US government cannot be granted a copyright. It is, instead, in the public domain, and can be used by anyone without restriction. Unfortunately, the use of this public domain footage in news broadcasts created by Scripps (owner of multiple TV stations as well as a significant ABC stakeholder) put a chain of events in motion that ultimately saw NASA's footage taken down by YouTube.
