Vanity.

From 'The Verge':

"NASA's original photo is somewhat obscured by a dust cover on the MAHLI camera used to capture the picture, but The Planetary Society's Emily Lakdawalla made the necessary touchups to reveal the memorable portrait above. That large "eye" you're looking at is actually one of Curiosity's most vital tools: it's a powerful laser capable of vaporizing Mars rocks and instantly analyzing their chemical composition as they vanish from sight."

"How long is a piece of string?"

A BBC Horizon documentary with Alan Davies (of QI: Quite Interesting fame) exploring the intricacies of measurement - from rulers to thought experiments and quantum mechanics.

Overall, the science and maths is a tad over simplified; I feel viewers could handle a little more detail.

This was overdue

To be watched in HD only! 

Video description:
"From the upcoming Special Edition Ascent: Commemorating Space Shuttle DVD/BluRay by NASA/Glenn a movie from the point of view of the Solid Rocket Booster with sound mixing and enhancement done by the folks at Skywalker Sound. The sound is all from the camera microphones and not fake or replaced with foley artist sound. The Skywalker sound folks just helped bring it out and make it more audible."
