Accuracy and precision make our dreams come true

In 2012, the landing ellipse for the Curiosity Lander was only 4 miles wide by 12 miles long,an area more than 200 times smaller than Viking's.This allowed NASA to target a specific spot in Gale Crater,a previously un-landable area of high scientific interest.While we ultimately strive for accuracy,precision reflects our certainty of reliably achieving it.With these two principles in mind,we can shoot for the stars and be confident of hitting them every time.
