The attitude dynamics and manoeuvre survey in this paper is performed for a mission scenario involving a penetrator-type spacecraft, a semi-rigid axisymmetric prolate spacecraft spinning around its minor axis of inertia, requested to perform a 90° spin axis reorientation manoeuvre. In contrast to most existing spacecraft only one attitude control torque is available, perpendicular to the spin a...

The magnetic field structures of two interplanetary coronal mass ejections (ICMEs), each observed by a pair of spacecraft close to radial alignment, have been analysed. The ICMEs were observed in situ by MESSENGER and STEREO-B in November 2010 and November 2011, while the spacecraft were separated by more than 0.6 AU in heliocentric distance, less than 4° in heliographic longitude, and less tha...

In the early system definition phase of any spacecraft development project there are few known parameters and many assumptions. Finding the optimum solution, from the wide variety of available technologies and techniques, is an onerous task for the development team who, for the sake of efficiency, depend on available analysis and simulation tools. While providing good support in the specific do...
