Ever since it was designed and built for the International Space Station, it has been known as the Node 2 module. Now thanks to students from across the United States, Node 2 also will be known as “Harmony.”

The pressurized module will act as an internal connecting port and passageway to additional international science labs and cargo spacecraft. In addition to increasing the living and working space inside the station, it also will serve as a work platform outside for the station's robotic arm.

Thousands of students from kindergarten to high school participated in the contest, writing essays and building scale models. View the gallery to see the models and learn more about the six winning schools.
