Science, 1971 Some consequences of Newtonian mechanics, previously overlooked, result in a new understanding of the behavior of small bodies in the solar system. Collisions between such bodies lead not to a scattering of these bodies over an increasing volume but instead to a contraction resulting in a "jet stream," with application to meteor streams and streams of ...

Modeling and Observer-Based Vibration Control of a Flexible Spacecraft With External Disturbances
IEEE transactions on industrial electronics (1982. Print), 2019This paper outlines the vibration reduction of a spacecraft with flexible appendage subject to external disturbances. The hybrid dynamic model of the spacecraft is described by both partial differential equations and ordinary differential equations.

Space Science Reviews, 2011
The Dawn spacecraft is designed to travel to and operate in orbit around the two largest main belt asteroids, Vesta and Ceres. Developed to meet a ten-year life and fully redundant, the spacecraft accommodates an ion propulsion system, including three ion engines and xenon propellant tank, utilizes large solar arrays to power the engines, carries the ...

Fixed-Time Attitude Tracking Control for Rigid Spacecraft Without Angular Velocity Measurements
IEEE transactions on industrial electronics (1982. Print), 2020This article considers the problem of velocity-free fixed-time attitude tracking control for rigid spacecraft. With the help of the homogeneity theorem, a semiglobal observer is introduced to estimate the unmeasured angular velocities within fixed time ...

Adaptive Fault-Tolerant Attitude Tracking Control of Spacecraft With Prescribed Performance
IEEE/ASME transactions on mechatronics, 2017The science objectives of a spacecraft mission place stringent performance requirements on the spacecraft attitude control system. However, it remains an open problem how to guarantee consistent control performance necessary to meet these requirements ...

Building the future of WaferSat spacecraft for relativistic spacecraft
SPIE Proceedings, 2016Recently, there has been a dramatic change in the way space missions are viewed. Large spacecraft with massive propellant-filled launch stages have dominated the space industry since the 1960’s, but low-mass CubeSats and low-cost rockets have enabled a new approach to space exploration. In recent work, we have built upon the idea of extremely low mass (
