This graphic shows the B-Plane for NASA's Mars 2020 Perseverance rover mission as of February 15, 2021. A B-Plane is a key performance metric that navigators for interplanetary missions use to determine the accuracy of their spacecraft's trajectory. The entry target on the lower right of the image (black cross) depicts the point where mission navigators are targeting the Mars 2020 spacecraft to enter the Red Planet's atmosphere. Higher up, the red, orange, green, and blue ovals depict the estimated "entry uncertainty ellipse" for the spacecraft as determined by previous navigation solutions. The inner-most ring (purple) depicts the most recent trajectory path.

NASA's Jet Propulsion Laboratory in Southern California built and manages operations of the Mars 2020 Perseverance rover for NASA.
