They are building an 'energy block' which will help leep the Station in the right place in space. Also, they are building a module that the astronauts can use to fly home in an emergency like the Soyuz. I will check it out. Woops, Are you working more with computers or wiring on the station I work with both. The computers are all wired together with what are called data buses.
Data buses are the cords that connect the computers together.
I have to look at what computers 'talk' on what buses to determine how to test them before they launch. Good luck to you, too. And thanks for your interest. Good luck to you as well.
