NASA’s Psyche Probe Heads to 16 Psyche for 2029 Arrival as 30%-60% Metal Mix Challenges Core Theory

Summary
NASA’s Psyche spacecraft is en route to asteroid 16 Psyche and is due to arrive in 2029, targeting a metal-rich body between Mars and Jupiter.
Newer models suggest Psyche is not a fully exposed planetary core but a rock-metal mix, with metal making up about 30% to 60% of its volume.
The mission is focused on science, not mining: the probe will measure composition, gravity and magnetic field, and search for signs of ferrovolcanism—possible ancient eruptions of liquid iron and nickel.
Big headline valuations for metal-rich asteroids remain theoretical because mining, refining, transport and market effects could erase economic viability; Psyche’s exact composition is still unknown until a spacecraft studies it directly.
Sample-return missions underscore the gap between science and industry—Hayabusa2 brought back 5.4 grams and OSIRIS-REx 121.6 grams—while many researchers see water ice for fuel and life support as the first practical space resource.
