Keeping your station working and safe for your astronauts is accomplished by keeping it supplied, maintaining the atmosphere, and keeping all the components in good repair. When a component is selected, there is a bar in the lower right hand panel that corresponds to its state of repair; a low red bar indicates it needs immediate attention. Components needing immediate repair will flash on the Imminent Event Bar in the upper left hand side of the screen. Click on the bar and you will zoom to that location. On the lower right panel, there is a set of tick marks that indicates the level of Astro Tech expertise an astronaut needs to be able to repair that component. If you attempt to have an astronaut repair something too high above their level, watch out!

To see what tasks are available for an astronaut to perform on a selected component, left click the component. This will cause one or more "Task Chips" to fly from the component down to the lower right Heads Up Display (HUD). To assign one of those tasks to the currently selected astronaut, just click on it and it will then fly up into the "Task List" in the upper left corner.

To change astronauts, click on the left or right arrows in the black astronaut box in the lower left corner. In this way you can quickly step through your roster of astronauts and assign them tasks to complete as well as review their progress with existing tasks. Sometimes an astronaut may get blocked from a task and will then give up, so keep a close eye on their activities!

Clicking on the astronaut in the panel will select the astronaut and take you to wherever in the station the astronaut is at the moment. This is a very useful feature when you have built a very large station. Notice that the astronaut's name appears in the lower right panel. You can also assign one astronaut to interact with another astronaut. To select an astronaut to act UPON, click on the astronaut image in the lower left corner. You will then fly to that astronaut and see their name appear in the lower right panel.
