The Near-Earth Asteroid Characterization and Observation (NEACO) mission is a concept
study proposing to explore the fast-rotating asteroid (469219) 2016 HO 3, one of Earth's few …

Asteroid 2016 HO3 is the first of the two small bodies in the Solar System targeted by the
Chinese Small Body Exploration Mission scheduled to be launched in the next few years. In …

This paper proposes an algorithm relying on range images to reconstruct the shape model
of the orbited object, train an uncertainty model representative of shape reconstruction …

This paper proposes a modified glideslope guidance method that optimizes a hybrid
multiobjective of bearing-only navigation error and fuel consumption. The traditional …

The exploration of small bodies in the Solar system and the ability to perform remote or in
situ science is tied to the understanding of the dynamical environment of such objects. As …

An accurate model of the gravity fields around irregular small bodies is significant for
exploration missions. However, it is difficult for classical modeling methods to guarantee …

Current methods for pose and shape estimation of small bodies, such as comets and
asteroids, rely on extensive ground support and significant use of radiometric measurements …

The exploration of the planets of the solar system using robotic vehicles has been underway
since the early 1960s. During this time the navigational capabilities employed have …

Abstract In October 2016, ESA's Trace Gas Orbiter entered into orbit around Mars. The
transfer from its initial 24-hour elliptical orbit into the final 2-hour science orbit was helped by …

SPACECRAFT navigation in proximity to small celestial bodies, such as asteroids and
comets, is challenging due to the complex dynamic environments of the bodies and their …
