The ESA says that its new laser communications network will create what it calls a “SpaceDataHighway,” able to transfer information such as photos and videos from Earth observation satellites, drones, and even from the International Space Station down to Earth at a near real-time speed of 1.8 Gigabits per second. This is 90 to 100 times faster than the speed of a home Internet connection, says the ESA.
