The GPM Core Observatory completed final checks and the team is preparing to install it in the transportation canister that will move it to the spacecraft and fairing assembly building at JAXA’s Tanegashima Space Center, Japan. There, the spacecraft will be fueled next week, followed by installation into the fairing that will contain the spacecraft on the top of the H-IIA rocket.

The launch vehicle for the Global Precipitation Measurement, or GPM, mission's Core Observatory arrived at Tanegashima Space Center, Japan, in the pre-dawn hours of Tuesday, Jan. 21, local time. The Japanese H-IIA rocket, No. 23, has two stages that arrived by cargo freighter the previous evening. They were then trucked across the island in the middle of the night when no cars were on the road.

The Global Precipitation Measurement (GPM) Core Observatory had a busy week at Tanegashima Space Center, Japan. The GPM propulsion team did a thorough check of the propulsion system to prepare for fueling the spacecraft later this month. In addition, the GPM completed a full End-to-End test. End-to-End testing simulates mission conditions with the ground systems and communication systems between the spacecraft, data return functions, the Mission Operations Center and...

Following arrival at Japan’s Kitakyushu Airport at 10:30 p.m. EST Saturday, Nov. 23, the GPM Core Observatory spacecraft in its shipping container was off-loaded from the C-5 aircraft and moved to a barge to be transported to Tanegashima Island. The barge departed Kitakyushu around 6:30 a.m. EST Sunday, Nov. 24, but a third of the way to the island, an unplanned stop had to be made at a port called Saiki to protect the ship from weather and rough seas. The barge arrived at Shimama...

NASA's Dual-frequency, Dual-polarization, Doppler Radar (D3R) was transferred from GSFC to Wallops this week. D3R's dual frequencies match those of the GPM DPR radar. Some work to the D3R computing infrastructure will be performed at Wallops, and then the radar will be collocated with NASA's NPOL radar in Newark, MD.

GPM has successfully completed post-environmental Comprehensive Performance and Functional testing. These tests are performed to verify that the GPM Core satellite still meets all of its requirements after completing a suite of environmental tests (thermal/vacuum, electromagnetic interference/electromagnetic compatibility, vibration/acoustic/shock). The satellite is now being prepared for shipment to the HII-A launch site in Tanegashima, Japan.
