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.
