Kidding, of course. But, in space NASA is. Click the picture for the full story and cool vid.

In the video shock diamonds are cleary visible in the engine blast.
What? Shock diamonds. Also known as Mach disks, they are interference patterns formed by shock waves propagating down the engine's exhaust plume. Shock diamonds are formed when exhaust exits a nozzle supersonically and at a pressure different than that of the ambient atmosphere. The most famous photo of shock diamonds shows Chuck Yeager's X-1 rocket plane just moments after he first reached Mach 1 on Oct. 14, 1947. SPEED BABY!
