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

The GPM Core Observatory has received a green light for launch! On the morning of Feb. 26 (Japan time) at Tanegashima Space Center, chief officers from Mitsubishi Heavy Industries, Ltd., the Japan Aerospace Exploration Agency (JAXA) and NASA reviewed the readiness of the Global Precipitation Measurement (GPM) Core Observatory for launch on an H-IIA rocket on Feb. 28 (Japan time). All launch vehicle and launch facility actions relevant to the GPM launch were reported complete. The review panel...
Launch services provider Mitsubishi Heavy Industries (MHI) performed checks on the propulsion and electrical systems on the H-IIA rocket that will carry the GPM Core Observatory into space.
On Tuesday, Feb. 25 (Japan time) at the Tanegashima Space Center, Japan, pyrotechnics were connected on the H-IIA launch vehicle that will carry the NASA-JAXA Global Precipitation Measurement (GPM) Core Observatory into space. In addition, the attitude control system that will control the second stage of the launch vehicle was fueled.
Preparations for the launch of the NASA-JAXA Global Precipitation Measurement (GPM) Core Observatory continue on schedule at Tanegashima Space Center, Japan. Launch is scheduled for Thursday, Feb. 27 U.S. time / Friday, Feb. 28 Japan time.vThe Core Observatory is now encapsulated in the fairing and installed on the second stage of the H-IIA rocket in the Vehicle Assembly Building. On Feb. 19 and 20 (JST), the Core Observatory and the launch vehicle underwent the final functional test for two...
The Mitsubishi Heavy Industries team finished installing the GPM mission’s Core Observatory into the fairing. The main installation occurred on Feb. 13, and all final activities and checks concluded on Feb. 16. The fairing is the top part of the rocket that will protect the spacecraft during launch. Mitsubishi Heavy Industries moved the fairing containing the GPM Core Observatory to the vehicle assembly building on Feb. 18 at Tanegashima Space Center. Inside the vehicle...
On Feb. 11, the Core Observatory was moved into the spacecraft fairing assembly building and into the Encapsulation Hall. Final inspections and preparations were completed for the installation into the fairing, which began on Feb 13. The fairing is the part of the rocket that will contain the spacecraft at the top of the H-IIA rocket.
The Global Precipitation Measurement mission propulsion team completed fueling the Core Observatory spacecraft on Feb. 6 in the spacecraft and fairing assembly building at the Japan Aerospace Exploration Agency's Tanegashima Space Center, Japan. Afterward the propulsion team did leak checks. GPM's fuel is hydrazine, which will power GPM's 12 thrusters that are used to maneuver the spacecraft so that it first enters then maintains its final orbit 253 miles (407 km) above Earth's...
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...
