How astronauts use amateur radio to connect with Earth from orbit
In short: Traveling at 17,500 miles per hour, the International Space Station crew uses HAM radio to bridge the gap between orbit and Earth, engaging students in science and technology.
The video features Expedition 25 commander Doug Wheelock providing a tour of the Russian segment and the docked Soyuz spacecraft. Using the call sign NA1SS, Wheelock demonstrates how the station's amateur radio facilitates communication with people on the ground.
This connection is part of the Amateur Radio on the International Space Station (ARISS) program. Since November 2000, the initiative has hosted over 1,700 events, reaching students across 63 countries, 49 U.S. states, and all seven continents to encourage interest in STEM.
