Contacting the International Space Station

Kép
The International Space Station (ISS) is a huge (>400 tonnes mass, >900m3 pressurized volume) habitable satellite on low earth orbit. It orbits the Earth at about 400km high with a speed of 7.67km/s (27,600 km/h), and goes around it in about every 93 minutes. It's permanently crewed, can support up to 6 astronauts, and provides a platform for many scientific experiments. Besides astrobiology, astronomy, materials science, and many other fields, it hosts experiments for the ARISS - "Amateur Radio on the International Space Station" project. ARISS experiments give opportunities to observe or even contact the station with simple amateur radio equipment.
