Electromagnetic pulses generated by meteoroid impacts on spacecraft
[1] Meteoroid impacts on spacecraft are known to cause mechanical damage, but their electrical effect on spacecraft systems are not well characterized. Several reported spacecraft anomalies are suggestive of an electrical failure associated with meteoroid impact. We present a theory to explain plasma production and subsequent electric fields occurring when a meteoroid strikes a spacecraft, ioni...
متن کاملAntifungal properties of electrically generated metallic ions.
A qualitative and quantitative investigation was undertaken to study the susceptibility of unicellular eucaryotic organisms (yeasts) to metallic cations generated by low levels of direct current. Results were characteristic of effects obtained previously using clinical and standard bacteria test organisms. The present study demonstrated that anodic silver (Ag(+)) at low direct currents had inhi...
متن کاملDevelopment and Testing of Automatically-generated Acs Flight Software for the Map Spacecraft
Using integrated analysis and design tools for the development of spacecraft attitude control systems (ACS) can make the process much more efficient, requiring less time and effort than before. The integrated toolset used for the development of the ACS of the Microwave Anisotropy Probe (MAP) spacecraft includes the ability to automatically generate software from the MAP high-fidelity (HiFi) sim...
متن کاملMultiple Quantum Well Retromodulators for Spacecraft - To - Spacecraft Laser Interrogation
This paper describes a novel concept for laser-based interrogation, communication, and navigation between multiple spacecraft platforms using a gimbaled laser source on a pursuer spacecraft and a target board populated with retromodulators (modulating retroreflectors) integrated on a host spacecraft. The combined laser source and retroreflectors can provide centimeter-level relative positioning...
متن کاملA Global Spacecraft Control Network for Spacecraft Autonomy Research
The Stanford Space Systems Development Laboratory (SSDL) has initiated the development and integration of a worldwide space control network. This network will serve as a command and control architecture for scholastic and amateur spacecraft. In addition, it will offer a unique real world testbed for the application and validation of advanced autonomous spacecraft operations strategies. The prop...
