The European Space Agency released a sequence on November 5 showing its Hera spacecraft approaching the asteroids Didymos and Dimorphos. In the first frame, taken on October 5 from about 270,280 kilometres away, the pair appeared as one bright point. Hera’s camera took the last frame in the sequence on October 27 from 360 kilometres away. ESA plans to release detailed images of both asteroids on November 25. [evidence-1]
Dimorphos orbits the larger Didymos. NASA deliberately struck Dimorphos with its DART spacecraft in September 2022, shortening the time the smaller asteroid takes to circle Didymos by about 33 minutes. ESA plans to examine the effects of that impact up close. The survey is intended to help researchers understand how a spacecraft collision could be used to change an asteroid’s path.
