NASA

NASA stands for National Aeronautics and Space Administration. NASA was started in 1958 as a part of the United States government. NASA is in charge of U.S. science and technology that has to do with airplanes or space.

What does NASA do?
NASA does a lot of different things. NASA makes satellites. The satellites help scientists learn more about Earth. NASA sends probes out into space. NASA scientists study things in the solar system and even farther away. A new program will send humans to explore asteroids, Mars and beyond. People at NASA work on ways to make air travel better for everyone on Earth, too. People at NASA also share the things they learn with others. This can help make life on Earth better.

The daily used communication of NASA

Sound cannot travel through the vacuum of space, but visible light and other forms of electromagnetic radiation can. One of these forms is commonly called radio. The astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit it to the ground (or other astronauts in space). This is exactly the same as how your radio at home works.

DSN

The NASA Deep Space Network (DSN) is an international network of antennas that provide the communication links between the scientists and engineers on Earth.
The DSN consists of three deep-space communications facilities placed approximately 120 degrees apart around the world: at Goldstone, in California's Mojave Desert; near Madrid, Spain; and near Canberra, Australia
