Welcome to JPL's mission control, where our engineers send and receive signals to communicate with NASA spacecraft.
Virtual visitors stand in the viewing gallery. They see Hal, an engineer, who is seated at a table with several monitors. Behind Hal, a large mission board displays planets in our solar system and the general location of spacecraft. Hal explains that the engineers send signals through the giant antennas of the Deep Space Network. This signals travel at the speed of light, so it only takes a few minutes to reach a spacecraft at Mars. It takes more than 12 hours to get to our most distant spacecraft, Voyager 1.
