Views of the Didymos and Dimorphos binary asteroid system obtained from radar facilities at NASA Jet Propulsion Laboratory’s Goldstone planetary radar in California and the National Science Foundation’s Green Bank Observatory in West Virginia. Shown at left are Oct. 4, 2022, observations from Goldstone observations; at right are combined Goldstone and Green Bank observations from Oct. 9, 2022. The vertical axis shows radar range, or the distance from Earth, and the horizontal axis shows Doppler, or line of sight velocity. The final slide in the movie shows the difference between where Dimorphos is observed compared to where it would have been with the original orbit.
