Mr. Musk doesn't know. He has no control over the satellites, which move in space at a speed of eight kilometres per second and whose trajectories are unknown. This poses a problem. As an engineer, I calculated the kinetic energy associated with a 260-kilogram satellite moving at eight kilometres per second. It amounts to two tons of TNT moving through space and not being tracked closely.
All our GPS satellites, especially for meteorology, are part of these “bombs”. We need to deal with this. The people at NASA said that the most important thing for the whole world and for our planet was that the observation of climate change was being done from space. The same is true for all our financial transactions. Losing access to space would be a major issue.
