Mission Updates

The High Gain Antenna System (HGAS) completed vibration test and moved to the acoustic chamber for the acoustic test at Goddard Space Flight Center. The HGAS helps to provide directional pointing for the Radio Frequency communications antenna, used with NASA’s Tracking and Data Relay Satellite System. 
The GPM Core Observatory structure successfully completed proof testing in the centrifuge facility at Goddard Space Flight Center. The satellite was tested at several different angles to simulate the increased feeling of gravity’s pull on the satellite during launch. Goddard's centrifuge can accelerate 2.5 tons to speeds so high that the payload experiences forces 30 times greater than the pull of Earth's gravity.
GPM has successfully completed the GPM Mission Critical Design Review (CDR) on December 17, 2009. During this phase of the mission the activities are focused on the implementation of science and engineering plans for the mission. The engineering activities are focused on: Core Observatory development (in-house development at Goddard Space Flight Center, Greenbelt Maryland) GPM Microwave Imager (GMI) instrument development for flight units 1&2 (at Ball Aerospace, Boulder...
GPM has successfully completed the GPM Mission Key Decision Point - C (KDP-C) Review on December 2, 2009, which formally confirms the Implementation phase of the GPM Mission. Key Decision Point C (KDP-C) is the agency-level approval for the project to begin implementation, and baselines the project’s official schedule and budget.
