PhD student Harrison Agrusa from the University of Maryland has been simulating the interaction between the fridge-sized DART spacecraft and smaller 160-m diameter Didymos asteroid hundreds of times, run on his university’s powerful computing cluster. His simulations recreate the 780-m diameter main Didymos asteroid and its orbiting ‘Didymoon’ as a collection of small spheres – like the rubble piles that researchers believe these bodies to resemble – then apply the equivalent force of the DART impact.
