ESTRACK

Estrack is like a phone network for spaceships. Just as you need a phone connection to call someone far away, a spaceship needs a connection to Earth when it is in space. Estrack makes this possible by using big antennas on Earth to send signals to the spaceship and receive signals from it. It's like playing catch with a ball, but instead of a ball, it's sending and receiving information. This helps scientists and engineers control the spaceship and get data from it, which are very important for exploring space. Basically, Estrack is like a big, powerful space phone service that helps Earth communicate with spaceships.
