Recent advancements in supercomputer simulations have opened up new possibilities for protecting spacecraft powered by electric propulsion from their own exhaust. These spacecraft, which use electrostatic or electromagnetic fields to accelerate propellant to high speeds, generate a plume of charged particles that can potentially damage sensitive components like solar panels and communication antennas.
The new simulations have provided valuable insights into the behavior of the exhaust plume, including the movement of electrons within it. By understanding these dynamics, scientists can develop strategies to mitigate the impact of the exhaust on the spacecraft. One potential solution is to design the spacecraft's shape and orientation in a way that minimizes exposure to the most damaging parts of the plume. Another approach involves using magnetic fields to deflect the charged particles away from critical components.
These advancements in simulation technology are expected to play a crucial role in the development of more efficient and reliable electric propulsion systems for future space missions.
