GPM Core Observatory

Fairing Attached to HII-A Rocket

The Global Precipitation Measurement Core (GPM) Observatory is scheduled to launch on Feb. 27 (EST) from Tanegashima Space Center, Japan.

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.

GPM Launch Party at NASA Goddard

NASA's Goddard Space Flight Center in Greenbelt, Md., is opening its Visitor Center to the public for a family-friendly activity-filled Global Precipitation Measurement launch party from noon to 3 p.m. EST Feb. 27, 2014. We will watch a live NASA Television broadcast of the launch of the GPM Core Observatory from Tanegashima Space Center in Japan. We will have expert presentations and family-friendly, hands-on demonstrations. The launch of the GPM Core Observatory is scheduled for no earlier than 1:07 p.m. EST.

GPM Spacecraft Completes Fueling

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 surface. GPM will carry enough fuel for a minimum of five years of mission life.

GPM Completes Final Checks, Prepares for Fueling

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.
