Annual Review of Control, Robotics, and Autonomous Systems, 2022
This article provides a survey overview of the techniques, mechanisms, algorithms, and test and validation strategies required for the design of robotic grappling vehicles intended to approach and grapple free-flying client satellites. We concentrate on using a robotic arm to grapple a free-floating spacecraft, as distinct from spacecraft docking and ...

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 ...

Determination of the Range of the Spacecraft
2019 International Siberian Conference on Control and Communications (SIBCON), 2019As a result of the gravitational attraction of the Sun/Moon/Earth, the pressure of solar radiation and other factors, the spacecraft located in the geostationary orbit deviates from the real orbit. The position of the spacecraft is regulated by a short pulse switching by correcting engines.

The Giotto spacecraft (Fig. 1), the first ESA (European Space Agency) interplanetary probe, was designed to flyby comet Halley. Launched on 2 July 1985 by an Ariane-1 rocket from Kourou, Giotto succeeded in approaching the cometary nucleus to within 600 km on 14 March 1986. Through its first accurate images of a nucleus and in situ studies of gases and

SIMULATION, 1963
Computer simulation of electro/mechanical systems has become so important in our world of technical complexity that to many of us the very word "Simulation" has come to suggest first---if not exclusively---just that; the computer simulation of complex physical systems.

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 (

Spacecraft charging - An update
34th Aerospace Sciences Meeting and Exhibit, 1996Summary form only given. Nearly twenty years after the landmark SCATHA program, spacecraft charging and its associated plasma interactions continue to be major issues for Earth-orbiting spacecraft. Although typically thought of as a surface effect on geosynchronous spacecraft, internal charging and low-altitude phenomena are increasingly causing ...

Proceedings of the First NASA/DoD Workshop on Evolvable Hardware, 2003
Two major steps in the evolution of autonomous, longlife spacecraft computing systems have been the demonstrations of systems with one-year and ten-year life expectancies in space. This paper discusses the design concept of a distributed, diversified self-testing and self-repairing computing system that is embedded in an autonomous spacecraft and ...

IEEE Software, 2013
How much software does it take to land a spacecraft safely on Mars, and how do you make all that code reliable? This column describes such a software development process. The first Web extra at http://mars.jpl.nasa.gov/multimedia/videos/movies/miam20121218/miam20121218-1280.mov is a 60-second video from NASA's Jet Propulsion Laboratory that shows how ...
