A little more than 100 years ago, humans learned how to make radio waves, too. Radio waves hit Earth all the time from stars, galaxies and even some planets (Jupiter is a good example). Radio waves are like light waves, but much longer, so our eyes cannot see them. The DSN’s huge, dish-type antennas are specially designed to detect radio waves - and very faint ones at that. So as Earth turns, at least one set of antennas is pointed in the direction of far-away spacecraft at all times. One set is in California, one set is in Spain, and one set is in Australia. The Deep Space Network has three sets of antennas, spaced at locations more or less equidistant around the Earth. After gaining familiarity, students will be able to hear patterns more easily and stopping won't be required as frequently. At first, it might be a good idea to stop after each pattern of four beats to discuss what the students heard and whether what they heard represents a 1 or a 0.Once students are more familiar, any student wishing to be the Sig can volunteer. When first starting, the teacher can be the "Sig" (explained below) in order to reduce errors while students are still learning the code.This is a whole-class activity, but students can work in small groups to practice transmission skills after the initial practice.

After completing the first part of this exercise, extend the Message - even from across the classroom. Going at the speed of light, it can take quite a long time to transmit a Will realize pretty quickly that when these types of signals are not Fortunately, the signals students create in this The solar system, this activity teaches how signals travel at Understand how these signals are used to send data back and forth across But the DSN doesn't send and receive sounds it actually uses radio waves NASA's Deep Space Network is a series of antennas used to communicate This activity is part of our Engineering in the Classroom tool for educators!
