The Beresheet impact occurred on 11 April 2019 and LRO passed overhead 11 days later, allowing LROC to acquire a six-image (three NAC left-right pairs) sequence of the search area. The coordinates of the darkest pixel (lowest reflectance) of the central "smudge" are 32.5956°N, 19.3496°E . More:beresheet final trajectory |
