T-00:00 Liftoff
With its LE-7A main engine and two solid rocket boosters firing, the 174-foot-tall H-2A rocket lifts off from the Yoshinobu launch complex on Tanegashima Island. A few moments later, the rocket will complete a pitch program to head southeast from the launch site.
T+01:39 SRB-A Burnout
The H-2A's two solid rocket boosters exhaust their propellant and burn out at an altitude of 29 miles.
T+01:48 SRB-A Separation
The two solid rocket boosters are jettisoned.
T+04:05 Fairing Separation
After traversing the dense lower atmosphere and reaching an altitude of 92 miles, the rocket releases the 4-meter (13.1-foot) diameter payload fairing protecting the GPM Core spacecraft during the early part of the flight.
T+06:36 Main Engine Cutoff
After consuming its liquid hydrogen and liquid oxygen propellants, the LE-7A first stage main engine shuts down. The first stage and solid rocket boosters push the rocket to a velocity of more than 11,000 mph.
T+06:44 Stage Separation
The H-2A rocket's first stage is separated now, having completed its job. The spent stage will fall into the Pacific Ocean downrange from Tanegashima.
T+06:50 Second Stage Ignition
With the first stage jettisoned, the rocket's second stage takes over. The LE-5B hydrogen-fueled engine ignites at an altitude of 148 miles to accelerate the GPM Core payload to orbital velocity.
T+14:58 Second Stage Cutoff
The LE-5B second stage engine shuts down after reaching its specified orbital targets at an altitude of 248 miles and an inclination of 65 degrees.
T+15:49 GPM Core Separation
The 8,488-pound Global Precipitation Measurement Core Observatory is deployed from the H-2A rocket. Seven small secondary payloads will be released a few minutes later.
