The Design of a Space-based Observation and Tracking System for Interstellar Objects
Ravi teja Nallapu, Yinan Xu, Abraham Marquez +2
The recent observation of interstellar objects, 1I/Oumuamua and 2I/Borisov cross the solar system opened new opportunities for planetary science and planetary defense. As the first…
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…
Towards End-To-End Design of Spacecraft Swarms for Small-Body Reconnaissance
Ravi Teja Nallapu, Jekan Thangavelautham
The exploration of small bodies in the Solar System is a high priority planetary science. Asteroids, comets, and planetary moons yield important information about the evolution of…
Cooperative Multi-spacecraft Observation of Incoming Space Threats
Ravi teja Nallapu, Jekan Thangavelautham
Earth is constantly being bombarded with material from space. Most of the natural material end up being dust grains that litter the surface of Earth, but larger bodies are known to…
Building Small-Satellites to Live Through the Kessler Effect
Steven Morad, Himangshu Kalita, Ravi teja Nallapu +1
The rapid advancement and miniaturization of spacecraft electronics, sensors, actuators, and power systems have resulted in growing proliferation of small-spacecraft. Coupled with…
Spacecraft Swarm Attitude Control for Small Body Surface Observation
Ravi Nallapu, Jekan Thangavelautham
Understanding the physics of small bodies such as asteroids, comets, and planetary moons will help us understand the formation of the solar system, and also provide us with resourc…
Attitude Control of Spacecraft Swarms for Visual Mapping of Planetary Bodies
Ravi Teja Nallapu, Jekan Thangavelautham
Planetary bodies such as asteroids, comets, and planetary moons are high-value science targets as they hold important information about the formation and evolution of our solar sys…
A Cubesat Centrifuge for Long Duration Milligravity Research
Erik Asphaug, Jekan Thangavelautham, Andrew Klesh +5
We advocate a low-cost strategy for long-duration research into the 'milligravity' environment of asteroids, comets and small moons, where surface gravity is a vector field typical…
Precise Pointing of Cubesat Telescopes: Comparison Between Heat and Light Induced Attitude Control Methods
Ravi teja Nallapu, Jekan Thangavelautham
CubeSats are emerging as low-cost tools to perform astronomy, exoplanet searches and earth observation. These satellites can target an object for science observation for weeks on e…
