 This team argued that 16 Psyche would be a valuable object for study because it is the only metallic core-like body discovered so far.The spacecraft would orbit Psyche for 20 months, studying its topography, surface features, gravity, magnetism, and other characteristics and would be based on current technology, avoiding high cost and the necessity to develop new technologies.On 30 September 2015, the "Psyche" orbiter mission was one of five Discovery Program semifinalist proposals.
