Mission Status

March 2015

The GPM Core Observatory successfully launched from Tanegashima Space Center, Japan, on February 27th, 2014 at 1:37pm EST. It is currently in orbit, and data from the mission is available for the public to download from a variety of sources and formats which are outlined on the PMM Data Access page.

Mission Updates

NASA and JAXA selected 1:07 p.m. to 3:07 p.m. EST Thursday, Feb. 27 (3:07 a.m. to 5:07 a.m. JST Friday, Feb. 28) as the launch date and launch window for a Japanese H-IIA rocket carrying the Global Precipitation Measurement (GPM) Core Observatory satellite from JAXA's Tanegashima Space Center.
On Dec. 15, the Global Precipitation Measurement Core Observatory team completed the post-shipment Comprehensive Performance Test with no significant problems. The testing took seven days to run through each of the spacecraft's systems and subsystems to ensure that the satellite is ready for space.
The Global Precipitation Measurement mission's Core Observatory began its final Comprehensive Performance Test at Tanegashima Space Center in Japan on Dec. 9, 2013. The test will run 24/7 over the next few weeks as every system and subsystem is turned on and run through its tasks.  
Following the Global Precipitation Measurement Core Observatory’s arrival at the Tangashema Space Center in Japan, efforts by the NASA and Japan Aerospace Exploration Agency team will now focus on final checkouts and preparation for launch in early 2014.  
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.
The Sixth International Ground Validation Workshop will be held November 5 -7 in Rome, Italy, at the headquarters of the National Research Council of Italy (CNR), Institute of Atmospheric Sciences and Climate (ISAC). The workshop is organized in coordination with NASA’s Precipitation Measurement Missions Science Program. 
The GPM Core satellite successfully completed vibration testing in July 2013, at NASA's Goddard Space Flight Center, Greenbelt, Md. The tests ensure that the spacecraft can withstand the vibrations caused by the Japan Aerospace Exploration Agency (JAXA) H-IIA rocket during satellite’s launch early in 2014. Sitting on a specialized mobile platform, the GPM spacecraft was abruptly moved back and forth in each of its three spatial orientations.
The GPM Core Observatory completed the EMI/EMC test at Goddard Space Flight Center in May 2013. The Observatory is now going through pre-vibration activities, including solar array deployments.
