Stability of a Rotating Asteroid Housing a Space Station [PDF]

Frontiers in Astronomy and Space Sciences, 2019
Today there are numerous studies on asteroid mining. They elaborate on selecting the right objects, prospecting missions, potential asteroid redirection, and the mining process itself.

The dependence of asteroid rotation on composition

Astronomy & Astrophysics
Context. The rotational properties of asteroids provide critical information about not only their internal structure, but also their collisional and thermal histories.

Mirror formation control in the vicinity of an asteroid [PDF]

, 2008
Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

On the consequences of a fragmentation due to a NEO mitigation strategy [PDF]

, 2008
The fragmentation of an Earth threatening asteroid as a result of a hazard mitigation mission is examined in this paper. The minimum required energy for a successful impulsive deflection of a threatening object is computed and compared with the energy ...

Inelastic Collision Influencing the Rotational Dynamics of a Non-Rigid Asteroid (of Rubble Pile Type)

Mathematics, 2023
We have considered here a novel particular model for dynamics of a non-rigid asteroid rotation, assuming the added mass model instead of the concept of Viscoelastic Oblate Rotators to describe the physically reasonable response of a ‘rubble pile ...

Consequences of asteroid fragmentation during impact hazard mitigation [PDF]

, 2010
The consequences of the fragmentation of an Earth-threatening asteroid due to an attempted deflection are examined in this paper. The minimum required energy for a successful impulsive deflection of a threatening object is computed and compared to the ...

Physical Properties of the Young Asteroid Pair 2010 UM26 and 2010 RN221

The Astronomical Journal, 2023
The main belt asteroids 458271 (2010 UM26) and 2010 RN221 share almost identical orbital elements, and currently appear as comoving objects ∼30″ apart in the plane of the sky.

ROTATIONAL PROPERTIES OF THE MARIA ASTEROID FAMILY [PDF]

The Astronomical Journal, 2014
Maria family is regarded as an old-type (~3 +/- 1 Gyr) asteroid family which has experienced substantial collisional and dynamical evolution in the Main-belt. It is located nearby the 3:1 Jupter mean motion resonance area that supplies Near-Earth asteroids (NEAs) to the inner Solar System.

Passive sorting of asteroid material using solar radiation pressure [PDF]

, 2013
Understanding dust dynamics in asteroid environments is key for future science missions to asteroids and, in the long-term, also for asteroid exploitation.
