Investigating Asteroid Surface Geophysics with an Ultra-Low-Gravity Centrifuge in Low-Earth Orbit
Stephen R. Schwartz, Jekan Thangavelautham, Erik Asphaug +3
Near-Earth small-body mission targets 162173 Ryugu, 101955 Bennu, and 25143 Itokawa produce gravity fields around 4 orders of magnitude below that of Earth and their irregular shap…
Graze-and-Merge Collisions under External Perturbers
Alexandre Emsenhuber, Erik Asphaug
Graze-and-merge collisions (GMCs) are common multi-step mergers occurring in low-velocity off-axis impacts between similar sized planetary bodies. The first impact happens at somew…
GNC Challenges and Opportunities of CubeSat Science Missions Deployed from the Lunar Gateway
Himangshu Kalita, Miguel Donayre, Victor Padilla +6
The Lunar Gateway is expected to be positioned on-orbit around the Moon or in a Halo orbit at the L2 Lagrange point. The proposed Lunar Gateway is a game-changer for enabling new,…
Fate of the runner in hit-and-run collisions
Alexandre Emsenhuber, Erik Asphaug
In similar-sized planetary collisions, a significant part of the impactor often misses the target and continues downrange. We follow the dynamical evolution of "runners" from giant…
An Autonomous Passive Navigation Method for Nanosatellite Exploration of the Asteroid Belt
Leonard Vance, Jekan Thangavelautham, Erik Asphaug
There are more than 750,000 asteroids identified in the main belt. These asteroids are diverse in composition and size. Some of these asteroids can be traced back to the early sola…
Guidance, Navigation and Control of Asteroid Mobile Imager and Geologic Observer (AMIGO)
Greg Wilburn, Himangshu Kalita, Aman Chandra +3
The science and origins of asteroids is deemed high priority in the Planetary Science Decadal Survey. Major scientific goals for the study of planetesimals are to decipher geologic…
