derekmead writes "NASA's livestream coverage of the Curiosity rover's landing on Mars was practically as flawless as the landing itself. But NASA couldn't prepare for everything. An hour or so after Curiosity's 1.31 a.m. EST landing in Gale Crater,the space agency's main YouTube channel had posted a 13-minute excerpt of the stream. Ten minutes later, the video was gone, replaced with the message: 'This video contains content from Scripps Local News, who has blocked it on copyright grounds. Sorry about that.' That is to say, a NASA-made video posted on NASA's official YouTube channel, documenting the landing of a $2.5 billion Mars rover mission paid for with public taxpayer money, was blocked by YouTube because of a copyright claim by a private news service."
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
