NASA | GPM: Engineering Next Generation Observations of Rain and Snow

The video tutorial covers the comprehensive process of manufacturing, assembling, and testing the GPM spacecraft. It begins with the manufacturing of components and assembly of the spacecraft structure, followed by the integration of key instruments like the GPM Microwave Imager and the dual-frequency precipitation radar. Rigorous environmental testing ensures the spacecraft's durability in space. The video also highlights the logistical challenges of handling large spacecraft and the collaborative efforts of teams from NASA, JAXA, and Ball Aerospace. Finally, it details the final preparations for the spacecraft's shipment and launch.
