Second piece connected to the KSS

Year 15, Day 200

The KSA has finally launched KS-4 which brought the second part of the Kerbal Space Station into orbit; it actually includes several modules in one, each of them are: 

• Done&Dusted Lab Module
• Tranquil Node
• Cupola Module
• Kunity Hub Module
• Kwest Airlock
• Harmony Node

This marks a huge step forward in the construction of the station. Along with this, the first crew of the KSS is now onboard! They are scheduled to stay on the station for about 2 months and then return to Kerbin's surface, just as a test to see how living in space will affect future Kerbals from boarding the station.
