It's valid to perform research on Earth by taking satellite photos and examining them for land cover use. It's valid to use a laser range finder to map the land elevation of the entire planet. Among the various governments which have done this, Airbus has as well. Presumably to ensure nobody flies a plane into a mountain. If it's valid to shine a laser pulse from space/the sky onto the entire surface of the Earth (private property included) to determine the elevation of everything, it's valid to send TCP SYNs out to the entire surface of the internet.
