Although no known asteroid poses a threat to Earth for at least the next century, the
catalogue of near-Earth asteroids is incomplete for objects whose impacts would produce …

Hera is a planetary defense mission under development in the Space Safety and Security
Program of the European Space Agency for launch in 2024 October. It will rendezvous in …

When the OSIRIS-REx spacecraft pressed its sample collection mechanism into the surface
of Bennu, it provided a direct test of the poorly understood near-subsurface physical …

Images collected during NASA's Double Asteroid Redirection Test (DART) mission provide
the first resolved views of the Didymos binary asteroid system. These images reveal that the …

Asteroid interiors play a key role in our understanding of asteroid formation and evolution.
As no direct interior probing has been done yet, characterisation of asteroids' interiors relies …

The impactor-to-crater size scaling relationships that enable estimates of planetary surface
ages rely on an accurate formulation of impactor–target physics. An armouring regime …

Abstract NASA's Double Asteroid Redirection Test (DART) mission is the first full-scale
planetary defense mission. The target is the binary asteroid (65803) Didymos, in which the …

The mutual gravitational interaction of binary asteroids, which make up approximately 15 per
cent of the near-Earth asteroid (NEA) population, provides a continuous tidal force, creating …

The surface strength of small rubble-pile asteroids, which are aggregates of unconsolidated
material under microgravity, is poorly constrained but critical to understanding surface …

On 2022 September 26, the DART spacecraft will impact the surface of Dimorphos, the∼
160 m size satellite of the binary near-Earth asteroid (NEA)(65803) Didymos. What will be …
