Japan Aerospace Exploration Agency, or JAXA, President Keiji Tachikawa signs an agreement defining the terms of cooperation between NASA and JAXA on the Global Precipitation Measurement, or GPM, mission. The ceremony took place July 30 at the Kennedy Space Center Visitor Complex, Fla. Through the agreement, NASA is responsible for the GPM core observatory spacecraft bus, the GPM Microwave Imager, or GMI, carried by it, and a second GMI to be flown on a partner-provided Low-Inclination Observatory. JAXA will supply the Dual-frequency Precipitation Radar for the core observatory, an H-IIA rocket for the core observatory's launch in July 2013, and data from a conical-scanning microwave imager on the upcoming Global Change Observation Mission satellite.
