Dimorphos’s Orbit Period Change and Attitude Perturbation due to Its Reshaping after the DART Impact

The Planetary Science Journal
On 2022 September 26 (UTC), NASA's Double Asteroid Redirection Test (DART) mission achieved a successful impact on Dimorphos, the secondary component of the near-Earth binary asteroid system (65803) Didymos. Subsequent ground-based observations suggest a

Inflatable Dome for Moon, Mars, Asteroids, and Satellites

AIAA SPACE 2007 Conference & Exposition, 2007
On a planet without atmosphere, sustaining human life is very difficult and dangerous, especially during short sunlit period when low temperature prevails. To counter these environmental stresses, the author offer an innovative artificial "Evergreen" dome, an inflated hemisphere with interiors continuously providing a climate like that of Florida ...

9. Some Interrelations of Asteroids, Trojans and Satellites [PDF]

International Astronomical Union Colloquium, 1977
The Trojans of Jupiter have the same magnitude-frequency distribution as the asteroids, but there is a puzzling asymmetry of the densities in Preceding and Following Lagrangian points. The outer satellites of Jupiter have a peculiar magnitude-frequency distribution, with large and also small ones missing; they therefore cannot be captured asteroids or ...

Debris about asteroids: Where and how much? [PDF]

We summarize several recent findings on the size and shape of the region within which material can stably orbit an asteroid. If the asteroid (with assumed density 2.38 g/cu cm) circles the Sun at 2.55 AU, co-planar prograde material will remain trapped ...

Considering Contact Forces during the Formation of Planetesimals by Gravitational Collapse: Mutual Orbits, Spin States, and Shapes

The Astrophysical Journal
In this work, we apply a soft-sphere discrete element method (SSDEM) within the PKDGRAV N -body integrator to investigate the formation of planetesimal systems through the gravitational collapse of clouds of superparticles. Previously published numerical

High-speed Boulders and the Debris Field in DART Ejecta

The Planetary Science Journal
On 2022 September 26 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstration of a kinetic impactor concept.

Radar and Optical Observations and Physical Modeling of Binary Near-Earth Asteroid 2018 EB

The Planetary Science Journal
We report radar, photometric, and visible-wavelength spectrophotometry observations of NEA 2018 EB obtained in 2018. The radar campaign started at Goldstone (8560 MHz, 3.5 cm) on April 7, and it was followed by more extensive observations from October 5 ...
