The planetary and lunar ephemerides called DE440 and DE441 have been generated by
fitting numerically integrated orbits to ground-based and space-based observations …

Some years ago, the consensus was that asteroid (16) Psyche was almost entirely metal.
New data on density, radar properties, and spectral signatures indicate that the asteroid is …

The asteroid (16) Psyche may be the metal-rich remnant of a differentiated planetesimal, or it
may be a highly reduced, metal-rich asteroidal material that never differentiated. The NASA …

In order to improve our understanding of the interior structure of Saturn's small moon
Enceladus, we reanalyze radiometric tracking and onboard imaging data acquired by the …

Ceres, the only dwarf planet in the inner Solar System, appears to be a relict ocean world.
Data collected by NASA's Dawn spacecraft provided evidence that global aqueous …

Ceres, the most water-rich body in the inner solar system after Earth, has recently been
recognized to have astrobiological importance. Chemical and physical measurements …

NASA's OSIRIS-REx mission to asteroid (101955) Bennu relied on the production of real-
time shape models for both spacecraft navigation and scientific analysis. The primary …

The objective of the NASA Psyche mission gravity science investigation is to map the mass
distribution within asteroid (16) Psyche to elucidate interior structure and to resolve the …

Missions to small celestial bodies rely heavily on optical feature tracking for characterization
of and relative navigation around the target body. While deep learning has led to great …

We created high-resolution shape models of Phobos and Deimos using
stereophotoclinometry and united images from Viking Orbiter, Phobos 2, Mars Global …
