NASA | GPM in a Minute

What does building a satellite look like? In this timelapse of clean room footage from 2011 to 2014, watch the Global Precipitation Measurement mission's Core Observatory come together at NASA's Goddard Space Flight Center then fly across the Pacific where mission partner, the Japan Aerospace Exploration Agency, prepared and launched it into orbit, on Feb. 27, 2014.

The Global Precipitation Measurement mission observes rain and snowfall worldwide every three hours, which contributes to the monitoring and forecasting of weather events such as droughts, floods and hurricanes, as well scientific research on precipitation and climate change.
