Once the agreement is signed, ESA will begin manufacturing the first flight model of the International Polar Unit (IBDM), which will be used to interface with the ”Dream Catcher“ cargo system to the International Space Station. The ESA will invest 33 million euros to design the IBDM and will build a docking model for the first ”Dream Catcher" first cargo mission to be financed by the Sierra Nevada in the future. ESA reached an agreement with the Sierra Nevada in early 2014 to make it available to Dream Catcher by modifying IBDM
