Asteroids as a research area encompasses the scientific investigation of small rocky bodies primarily located in the asteroid belt and throughout the Solar System, focusing on their composition, internal structure, dynamical evolution, and role in planetary formation and collisional processes. This field integrates observational astronomy, spectroscopy, celestial mechanics, planetary geology, and space mission data to constrain asteroid taxonomies, surface and subsurface properties, impact hazards, and resource potential. Research addresses accretion and differentiation histories, space weathering, binary and rubble-pile formation, migration mechanisms, and their contribution to the delivery of volatiles and organics to terrestrial planets, providing constraints on early Solar System conditions.
The spacecraft aced its encounter with Mars. Now, mission scientists are studying a trove of data from the flyby in preparation for its arrival at asteroid Psyche in 2029.

Typically, astronomers identify comets by their distinct atmospheres, or comae, and their tails, which are created as the sun vaporizes a comet's ice. These features emit a glow when sunlight bounces off dust and water droplets. ...
A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within ...
