GPM Core Observatory

Live from Japan: GPM Tweet Chat Recap
Global Precipitation Measurement is a big mission. You've got questions? We've got answers. Three days before launch of the Global Precipitation Measurement (GPM) Core Observatory from Tanegashima Space Center in Japan, NASA staff supporting the mission set up shop in the lobby of the Sun Pearl Hotel in nearby Minamitane for a live Twitter Q-and-A to answer questions about the mission and what it will do in orbit. GPM Project Manager Art Azarbarzin and supporting staff Ellen Gray and Rani Gran taking part in the GPM Twitter Q-and-A from the Sun Pearl Hotel on Feb. 25. They were also joined by...

Art Azarbarzin, NASA's Global Precipitation Measurement mission project manager, and Mashahiro Kojima, the Japan Aerospace Exploration Agency's GPM/DPR project manager, reflect on the long journey the GPM Core Observatory spacecraft has taken to reach its last stop before orbit, the Tanegashima Space Center, Japan, from where the mission's Core Observatory is scheduled to launch on the afternoon of Feb. 27, 2014 (EST).

GPM Confirmed for Launch

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 gave the approval to proceed with launch.

GPM Undergoes Final Functional Tests

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. The 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 days. This test included power on/off operation of the launch vehicle and the spacecraft as well as

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.
