Preventive protection against thunderstorms during spacecraft launches

Satellites are a necessity in modern life for a variety of purposes (weather forecasting, scientific exploration, long-range communications, etc.). The vehicles that place satellites in orbit are sensitive to natural and rocket-induced lightning threats. That is why NASA developed the LLCC set of rules to assess whether the weather conditions permit the launches. Since its application, incidents such as those of Apollo 12 and Atlas-Centaur 67 have not occurred again. Within these criteria, the ambient electric field plays an essential role and is measured by a network of field mills (electrostatic field sensors) at the Kennedy Space Center.

What is a dry thunderstorm and what are its risks?

By definition, “a dry thunderstorm is a storm that has no or very little precipitation associated with it, but does carry electrical activity”. The absence of precipitation can create a false sense of security that poses a serious risk to the safety of people and structures. In this scenario, a system with sensors capable of detecting all phases of the storm and issuing warnings before the first impact can make a difference.
