Spacecraft formation flight exploiting potential fields
… system have led to the proposal of several multi-spacecraft missions by both NASA and DoD. One such benefit is the reconfigurability of these multi-spacecraft systems. This ultimately led to additional requirements being levied onto these missions, such as the general astrophysical imaging …

Statistical Study of Solar Wind Conditions Prior to Substorm Onsets
<p>Due to complex, multi-region, coupled plasma systems, auroral substorm onsets have been historically difficult to predict. The northward turning of the interplanetary magnetic field was considered the primary candidate as an external triggering mechanism for substorm onsets. However, that was …

Electromagnetic formation flight of satellite arrays
Proposed methods of actuating spacecraft in sparse aperture arrays use propellant as a reaction mass. For formation flying systems, propellant becomes a critical consumable which can be quickly exhausted while maintaining relative orientation. Furthermore, the total required propellant mass is …

Optimization of Spacecraft Formations about Lagrange Points for the Next Generation Space Weather Prediction Mission
… Generation Space Weather Prediction Mission, a multi-spacecraft mission at various libration points whose objective is to forecast Space Weather hazards with a 12day warning time. This thesis deals with the design and control of orbits of spacecraft formations at different libration points. The …

Health Management and Adaptive Control of Distributed Spacecraft Systems
… and collaborative inspection that involve multi-spacecraft systems increases, the requirements needed to improve post-failure safety to maintain the mission performance also increases, especially when operating under uncertain conditions. In particular, space missions that involve …
