Ast SpaceMobile is a company that is trying to provide internet and phone services to people around the world, including those living in remote areas, using satellites in space. It's like having a big invisible network of antennas that can send and receive information to and from anywhere on Earth.
Imagine if you have a toy car and you want to send it to your friend who lives on the other side of the room, but you can't walk over there. So instead, you give the car to your older brother who is standing in the middle of the room, and he throws it to your friend. That's kind of like what Ast SpaceMobile does but with information instead of a toy car.
They use a bunch of satellites in space that are like the middle man between your phone and the person you want to talk to. So, when you make a phone call or send a text message, your phone sends that information to the nearest satellite, which then beams it to another satellite, and then to your friend's phone. It's kind of like playing catch with a ball, where each satellite catches the information and throws it to the next one until it gets to the right place.
This way, Ast SpaceMobile can give internet and phone services to people in places where there are no phone towers, no cables, or anything else that could make communication possible, like in the middle of the ocean or in the middle of a desert. With the help of Ast SpaceMobile's satellites, people can stay connected all around the world.
