Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such materials,...

Designing any product — from complex car parts to wrenches — is a balancing act with conflicting performance tradeoffs. Making something lightweight, for instance, may compromise its durability.

Distributed systems have become an integral part of safety-critical computing applications, necessitating system designs that incorporate complex fault-tolerant resource management functions to provide globally coordinated operations with ultra-reliability. As a result, robust...

The Small-Body Dynamics Toolkit (SBDT) v5.0 is a collection of primitive-body-specific trajectory design and analysis tools written in MATLAB®. The SBDT gives the user the capabilities to propagate, analyze, and visualize spacecraft trajectories and the dynamical environment near realistic asteroid, comet,...

Soft landing using rockets requires a trajectory to be planned for the lander from rocket ignition — typically several kilometers in altitude and moving at up to 200 m/s — to the point near the surface with near-zero velocity. The exact...

NASA Marshall has developed a system for generating iodine vapor from solid iodine for use as a propellant in a Hall or ion thruster propulsion system. Xenon has generally been the preferred propellant for these spacecraft ion propulsion systems but more recently, iodine-based...
