GPM Completes Spacecraft Alignments
After a holiday break, final tests for the GPM Core Observatory resumed on Dec. 30, 2013, with alignment measurements. The spacecraft's instruments and components, such as star trackers and thrusters, are attached to the main body in specific configurations. Spacecraft alignment measurement is analogous to alignment for the wheels of a car. The Core Observatory measurements ensure that no parts have shifted during its transportation from the United States to Japan, so they will work as expected.

NASA Hosts Prelaunch Media Events for GPM
NASA will hold a series of media events Monday, Jan. 27, in advance of the February launch of the Global Precipitation Measurement (GPM) Core Observatory from Japan. The events will be held at NASA’s Goddard Space Flight Center in Greenbelt, Md. GPM is an international satellite mission led by NASA and the Japan Aerospace Exploration Agency (JAXA) that will provide next-generation observations of rain and snow worldwide. GPM data also will contribute to climate research and the forecasting of extreme weather events such as floods and hurricanes. The GPM Core Observatory is scheduled to lift...
Engineering the GPM Core Observatory
For the past three years, the Global Precipitation Measurement (GPM) Core Observatory has gone from components and assembly drawings to a fully functioning satellite at NASA's Goddard Space Flight Center in Greenbelt, Md. The satellite has now arrived in Japan, where it will lift off in early 2014. The journey to the launch pad has been a long and painstaking process. It began with the most basic assembly of the satellite's frame and electrical system, continued through the integration of its two science instruments, and has now culminated in the completion of a dizzying array of environmental...
NASA and JAXA Announce Launch Date for GPM
Environmental research and weather forecasting are about to get a significant technology boost as NASA and the Japan Aerospace Exploration Agency (JAXA) prepare to launch a new satellite in February. 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. GPM is an international satellite mission that will provide advanced observations of rain and snowfall...
GPM: The Road to Launch
The GPM Core Observatory has left NASA Goddard Space Flight Center and embarked upon its long journey to Japan where it will launch in early 2014.

GPM Delivered to Japan for 2014 Launch
An international satellite that will set a new standard for global precipitation measurements from space has completed a 7,300-mile journey from the United States to Japan, where it now will undergo launch preparations. A U.S. Air Force C-5 transport aircraft carrying the Global Precipitation Measurement (GPM) Core Observatory landed at Kitakyushu Airport, about 600 miles southwest of Tokyo, at approximately 10:30 p.m. EST Saturday, Nov. 23.

GPM Core Observatory in space with constellation satellites in background.
By Ellen Gray, NASA Goddard Space Flight Center Original www.nasa.gov Feature (published 4/12/13) This video, "Our Wet Wide World", provides an overview of the Global Precipitation Measurement Mission and its goals. Video Credit: Ryan Fitzgibbons As anyone who has ever been caught in a sudden and unexpected downpour knows, gaps still exist in our knowledge about the behavior and movement of precipitation, clouds and storms. An upcoming satellite mission from NASA and the Japanese Space Agency aims to fill in those gaps both in coverage and in scientists' understanding of precipitation. The...
