Updated B-plane map for the 2062 October 20 Didymos–Earth close approach. (a) Didymos coordinates on the close approach B-plane shown to scale. (b) Didymos position uncertainty shown to scale on the B-plane for the nominal (no deflection) case, the DART spacecraft contribution only (β _⊙ = 1) case, a single impulse at the time of impact in case 1, and multiple impulses for each escaping ejecta particle in case 2. (c) Didymos position uncertainty zoomed in to show details on the B-plane for the nominal (no deflection) case, DART spacecraft contribution only (β _⊙ = 1) case, single impulse at the time of impact in case 1 (β _⊙ = 1.789), and multiple impulses for each escaping ejecta particle in case 2.
