The large, four-screened Scanners provide all the data you know about the star system Zorica.
Firstly, it shows you the layout of the system, with the star Zorica at the centre, then the planets Perun, Veles and Jarilo, then the asteroid belt, and finally the icy planet Morena. The symbols and colours on the Scanners correspond to those you see when piloting your ship.
Secondly, it shows you where you picked up anything you have received so far. This is very useful if you haven't completed your collection of data. Stuck on Idris Kennedy - Personal Log part 1 of 4? Just hover over its name in the Scanner, and you can tell that you have to go to Perun to pick up the next three parts!
