Okay kiddo, you know how America and Russia used to not get along so well? Well, they had a really big competition to see who could be the best at space exploration. At one point, they wanted to work together and communicate with each other in space. So, they decided to build a space bridge, like a giant invisible phone line, that could connect America and Russia together in space. This way, they could talk to each other, share ideas, and learn from each other about space. They needed some special equipment and satellites to make it work, but in the end, it helped both countries learn more about the universe and become better friends!
