The Asteroid Impact & Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor to deflect an asteroid. AIDA is an international cooperation, consisting of two mission elements: the NASA Double Asteroid Redirection Test (DART) mission and the ESA Asteroid Impact Mission (AIM) rendezvous mission. The prima...

The Asteroid Impact and Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor to deflect an asteroid.

NASA is developing concepts for the Asteroid Redirect Mission (ARM), which would use a robotic spacecraft to capture a small near-Earth asteroid, or remove a boulder from the surface of a larger asteroid, and redirect it into a stable orbit around the moon. Astronauts launched aboard the Orion crew capsule and the Space Launch System rocket would rendezvous with the captured asteroid mass in lu...

Collisions in the asteroid belt frequently lead to catastrophic breakups, where more than half of the target's mass is ejected into space. Several dozen large asteroids have been disrupted by impacts over the past several billion years. These impact events have produced groups of fragments with similar orbits called asteroid families. Here we report the discovery of a very young asteroid family...

Introduction: The Rosetta mission to comet 67/P Churyumov-Gerasimenko is also scheduled to do two asteroid fly bys. The first of these was on Sept. 5 th , 2008, when the spacecraft flew within 800 km of asteroid 2867 Steins. The timing of the encounter meant that the surface of the asteroid (as seen from the spacecraft) was well illuminated, providing good imaging conditions. As well as providi...

A large disruption in the main asteroid belt can cause a large flux, an “asteroid shower”, on the terrestrial planets. We quantitatively examine the hypothesis that such an event was the cause of the lunar late heavy bombardment (LHB). We performed numerical integrations of about 20000 test particles starting in the vicinity of the ν6 secular resonance in the main asteroid belt. The purpose of ...
