Psyche is a NASA Discovery-class mission to map the surface and characterize
the composition of '16 Psyche', an elongated 280-km diameter metal-rich
asteroid located in the main asteroid belt between Mars and Jupiter. This
is the first mission to a metal-rich asteroid.
Unfortunately I missed it when it was close enough to see the modulation. These plots were when it was about 1.41Mkm from Earth.
