Magnetoshell provides a lightweight brake for spacecraft

NextBigFuture points to a neat concept for slowing a spacecraft when it enters an atmosphere. A study of the Magnetoshell concept was funded by the  NASA Innovative Advanced Concepts (NIAC). As shown in the slide below, the spacecraft would release a tethered device that creates a magnetized plasma, which in turn interacts with the atoms … Continue reading Magnetoshell provides a lightweight brake for spacecraft
