NASA before it got creative actually got curious.
Curiosity is one such quality which always amazes me. Had it not been for the curiosity of the human mind..... the world would have been different. Anyways back to the reason for this post and we will keep the post on curiosity for a different time.
Look at this great promotional video from Nasa. I love just for the sheer simplicity of the concept.
