This issue focuses on the Van Allen Probes mission and also highlights other exciting work at the Laboratory, including advances in additive manufacturing capabilities and a new methodology for evaluating a system’s risk and reliability. The issue begins with a brief biographical sketch and remembrance of James Van Allen, eponym of the Earth-encircling radiation belts and the successful mission investigating high-energy charged particles in space environments. Five articles present a comprehensive overview of the mission, the spacecraft, and observations and contributions to date. The final two articles discuss a new methodology that combines simulation with game theory to populate a fault tree, as well as Laboratory developments in additive manufacturing, including the recently established Additive Manufacturing Center of Excellence. The issue concludes with a Special Feature describing this year’s Achievement Award winners.
