During this cruise time it will fly by a few near Earth objects for study, including the transition body 3200 Phaethon in 2030, as well as measure interplanetary and interstellar dust.

[3][5][6] The probe's ion engines have the capability to perform another orbit transfer to study additional objects.

[1] DESTINY+ will be a technology demonstrator to further improve operations of low cost solar electric propulsion in deep space.

The scientific aspect of this mission is to understand origin and nature of dusts, which are key sources of organic compounds to Earth.

[2]) The total dry mass (excludes xenon propellant) of the ion engine system is 59 kg (130 lb).
