How Astronauts Get Internet In Orbit

How do astronauts on the International Space Station get internet 400 km above Earth? The answer involves relay satellites, radio signals, and some surprising delays. In this video, we break down how data travels from the ISS to ground stations and back, why the connection isn't like your home Wi-Fi, and how space agencies are improving it with new technology like laser communication. You'll learn: - How the ISS sends and receives data - What relay satellites do and why they're needed - Why astronauts don't just connect to a normal Wi-Fi network - Why space internet can be slower or delayed - How laser communication could change spaceflight SOURCES 1.
