Mars and Jupiter. The Psyche spacecraft will arrive at the asteroid in 2029. This image elements furnished by NASA. ______ Ur: https://www.nasa.gov/psycheWith last week’s successful launch of NASA’s mission to Psyche —- a largely unknown metal-rich asteroid on the outer edge of the Main Asteroid Belt, this mysterious planetoid could soon give up its secrets.
Once the NASA spacecraft arrives at Psyche in August of 2029, the spacecraft will over the next two years orbit the asteroid at a distance of about 700 km, says the Planetary Science Institute in Tucson. From there, it will progressively get closer to the planetoid as its instruments maps the surface and looks for evidence of an ancient magnetic field.
If it is a relict core of a planetesimal, it is likely to be among the oldest bodies in our solar system, Prettyman notes.As cosmic rays and high energy particles bombard the asteroid’s surface, elements there absorb the energy, says NASA. In response, they emit neutrons and gamma rays of varying energy levels.
The latter would indicate that at some point in its early history, Psyche’s interior structure had ‘differentiated’ into separate layers, usually structures of a core, mantle and crust.
