What the fuck has NASA done to make your life awesome?

Kid friendly version here

Grooves in pavement which led to safer driving & airplane takeoffs

Fail to Launch That rockets!

Whoa, Really?

"Carving a gro­ove into concrete may not sound like much of an innovation, but it certainly keeps us safe on the roads. Also called safety grooving, this simple, yet lifesaving, process inserts long, shallow channels into pavement on runways and roads. These indentions in the concrete divert excess water from the surface to reduce the amount of water between tires and the runway or road. This increases the friction between wheels and concrete, improving vehicle safety."
