Spacecraft swarm dynamics and control about asteroids [PDF]
Advances in Space Research, 2021 This paper presents a novel methodology to control spacecraft swarms about singleasteroids with arbitrary gravitational potential coefficients. This approach enablesthe use of small, autonomous swarm spacecraft in conjunction with a mothership,reducing the need for the Deep Space Network and increasing safety in future as-teroid missions.

The Perturbed Full Two-body Problem: Application to Post-DART Didymos
The Planetary Science Journal, 2023 With the successful impact of the NASA Double Asteroid Redirection Test (DART) spacecraft in the Didymos–Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid dynamics.

The Astronomical Journal, 2023 469219 Kamo‘oalewa is selected as one of the primary targets of Tianwen-2 mission, which is currently believed to be the most stable quasi-satellite of Earth. Here we derive a weak detection of the Yarkovsky effect for Kamo‘oalewa, giving A _2 = (−1.075 ±

Survey of secular resonances in the asteroid belt [PDF]
Serbian Astronomical Journal, 2022 Using a recently introduced synthetic method to compute the asteroid secular frequencies (Knežević and Milani 2019), in this paper we survey the locations of secular resonances in the 9 dynamically distinct zones of the asteroid belt.

Dynamics of the Hungaria asteroids [PDF]
Icarus, 2010 To try to understand the dynamical and collisional evolution of the Hungaria asteroids we have built a large catalog of accurate synthetic proper elements. Using the distribution of the Hungaria, in the spaces of proper elements and of proper frequencies, we can study the dynamical boundaries and the internal structure of the Hungaria region, both ...

Parking a Spacecraft near an Asteroid Pair [PDF]
, 2005 This paper studies the dynamics of a spacecraft moving in the field of a binary asteroid. The asteroid pair is modeled as a rigid body and a sphere moving in a plane, while the spacecraft moves in space under the influence of the gravitational field of

The relationship between the `limiting' Yarkovsky drift speed and asteroid families' Yarkovsky V-shape [PDF]
Serbian Astronomical Journal, 2020 The Yarkovsky effect is an important force to consider in order to understand the long-term dynamics of asteroids. This non-gravitational force affects the orbital elements of objects revolving around a source of heat, especially their semi ...

Dynamics of asteroid systems post-rotational fission
Astronomy & Astrophysics, 2022 Asteroid binaries found among the near-Earth objects are believed to have formed from rotational fission. In this paper, we study the dynamical evolution of asteroid systems the moment after fission. The model considers two bodies the moment after a contact binary separates due to rotational fission.

Deflecting small asteroids using laser ablation : Deep space navigation and asteroid orbit control for LightTouch2 Mission [PDF]
, 2013 This paper presents a low-cost, low mass, mission design to successfully intercept and deflect a small and faint, 4 m in diameter asteroid. Intended to be launched after 2025, the laser-ablating mission, LightTouch2 will be used to deflect the orbit of ...

Easily retrievable objects among the NEO population [PDF]
, 2013 Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also
