It discovered that asteroid Dimorphos wasn't the solid space rock we presumed.
suggests that the impact may have caused a significant change in the asteroid’s shape, providing insights into its composition.
If an asteroid with Dimorphos’s makeup were headed our way, the good news is – it might be easier to deflect than we thought! A “squishy” structure may respond very differently to an impact. Luckily, ESA’s Hera spacecraft is on a mission to investigate the aftermath firsthand. Launching in October, it will reach the asteroid by late 2026 and uncover DART’s detailed impact. The software was developed over 20 years ago at the University of Bern. It can mimic the bumpy breakup of rocky bodies by describing them as millions of particles. These particles interact based on various parameters such as density, material strength, and gravity.
