Abstract

Have you ever wished you could talk to an astronaut on board the International Space Station? You're probably thinking "yeah, like NASA would ever let you do that!" Actually, they will! The International Space Station (ISS) is equipped with its own HAM radio station. The ISS HAM radio station allows astronauts, cosmonauts, and space mission specialists from different nations who are on board the space station to talk to people back home on Earth. Anyone with an amateur radio license is welcome to try contacting the astronauts there. If they aren't busy with other activities, they'll answer!

Introduction

Making contact with the ISS requires some careful planning and logistics, though. The ISS is traveling approximately 240 miles above the surface of the Earth at a speed of nearly 17,000 miles per hour! To make contact, you'll need to carefully monitor the space station's trajectory and calculate your window of opportunity. The good news is, the ISS's high speed means it orbits Earth approximately 16 times a day, which gives you plenty of tries to get it right.

With a little bit of reading about the space station, you'll be ready to get your radio equipment in order and talk to the astronauts. For more suggestions on getting started, read the Science Buddies blog entry Making Contact with the Space Station and consult some of the resources in the Bibliography, below. Just make sure you document it all so your friends and your teacher don't think your project is just a piece of science fiction!

Career Profile
Mathematicians are part of an ancient tradition of searching for patterns, conjecturing, and figuring out truths based on rigorous deduction. Some mathematicians focus on purely theoretical problems, with no obvious or immediate applications, except to advance our understanding of mathematics, while others focus on applied mathematics, where they try to solve problems in economics, business, science, physics, or engineering.
