InterSPUTNIK is a big satellite club. Imagine you have a lot of different toys that you like to play with. You want to share your toys with your friends, but they live too far away to come over to your house to play with them. So, you decide to send some of your toys to your friends through the mail.
InterSPUTNIK works like that, but instead of toys, they share satellites - which are like big machines that can send and receive information like TV channels, internet, and phone calls. Different countries have different satellites, and some countries might not have any of their own satellites, so they need to borrow from others.
InterSPUTNIK helps countries to share satellites with each other, like how you share your toys with your friends. So, if one country has a lot of satellites and another country needs one, InterSPUTNIK will help them to share. By doing this, everyone can get access to different information from other countries, just like you get access to different toys when you share with your friends.
