DOS-7 (Updated Version)

It was the core module of Mir. There is an additional Solar Panel too and a high-gain antenna. It has the multiple Docking Ports node, from the Zarya Docking Ports Node. The module looks a lot like Zvezda.
Activation Groups and Inputs:
Manuevering Engines: Activation Group 2
These were 2 pressure-fed pixie engines to manuever the module. I made this activation group to make it easier for you to turn off the engines instead of just tapping them and turning them off. You don't have to worry about turning the throttle to 0% before turning them off. You have to click the activation group to turn them off without throttling it down to 0%. They will automatically ignite if the throttle is 100% before tapping the activation group.
Sun Sensors: Activation Group 3
Input: Slider 1
High-Gain Antenna: Activation Group 4
Input: Slider 1
Beacon Lights: Activation Group 5
Future Solar Panel: Activation Group 6
It was deployed after docking of Kvant-1.
Gyro: Activation Group 7
Solar Panels: Activation Group 9
Input: Slider 1
These were the main Solar Panels. I placed hinge rotators and rotators instead of the solar array in the game. Save it as a subassembly. It has 10 Docking Ports: 5 on the front and 1 on the back. The other 4 are the grapple fixtures. All activation groups with inputs (except for the sun sensors), place it on 100%. On the sun sensors, swipe the slider until the efficiency of the solar panels is 100% (pointed directly to the sun) after the solar panels are deployed. Put the subassembly to the Proton Rocket because it is the launch vehicle of it. The 3rd picture shows it placed on a Proton Rocket. The craft replaces the place of the Chandra X-ray Observatory as the most Complex craft I built. You know why? Because it has more parts than the Chandra X-ray Observatory that I built in SimpleRockets 2 had.
