GPM Core Observatory

GPM Core Observatory in space with constellation satellites in background.
By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Feature (published 4/12/13) This video, "Our Wet Wide World", provides an overview of the Global Precipitation Measurement Mission and its goals. Video Credit: Ryan Fitzgibbons As anyone who has ever been caught in a sudden and unexpected downpour knows, gaps still exist in our knowledge about the behavior and movement of precipitation, clouds and storms. An upcoming satellite mission from NASA and the Japanese Space Agency aims to fill in those gaps both in coverage and in scientists' understanding of precipitation. The...

GPM Undergoes Electromagnetic Testing

The GPM Core Observatory is continuing with the environmental test program at NASA Goddard Space Flight Center. Following the completion of thermal vacuum testing in January 2013, the Core Observatory team started the Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) test phase. The Core Observatory has successfully completed the Radio Frequency (RF) Self-Compatibility test and is being prepared for the next step of EMI/EMC test program. The EMI/EMC test program is expected to be completed in April 2013.

GPM Completes Thermal Vacuum Testing

This animation shows the launch and deployment of the GPM Core Observatory. GPM is scheduled to launch in 2014 on an H-IIA rocket in Japan.

GPM Continues Environmental Testing

The GPM Core spacecraft has completed hot and cold thermal balance testing in the thermal vacuum chamber at NASA's Goddard Space Flight Center. Next it will undergo hot and cold cycle thermal vacuum testing, where the temperatures are alternatively raised to 104°F (40 degrees C) and lowered to 7°F (-14 degrees C) over the course of the next few weeks. Thermal vacuum testing is part of GPM's environmental test program to ensure that the satellite is ready for the harsh conditions of space and will continue into mid-January.

Core Observatory Enters TVAC Chamber

(ambient audio only) On Tuesday Nov. 13, 2012, the GPM observatory moved from the clean room to the thermal vacuum chamber. The spacecraft, wrapped in protective blankets, made the short trip by crane across the testing facility where it was then lowered into the 40-foot test chamber.
