Epsilon launch timeline
Posted: August 26, 2013

T-00:00 Liftoff
The first stage's SRB-A solid rocket motor ignites and propels the 100-ton Epsilon rocket away from the Uchinoura Space Center. The SRB-A motor produces 510,000 pounds of thrust at full power.
T+01:52 Stage 1 Burnout
The Epsilon's SRB-A first stage, derived from boosters on the H-2A and H-2B rockets, burns out at an altitude of 54 miles.
T+02:30 Fairing Jettison
The rocket's 8.2-foot diameter payload fairing is released at an altitude of 91 miles.
T+02:41 Stage 1 Separation
The Epsilon's empty first stage separates moments before ignition of the rocket's second stage motor.
T+02:45 Stage 2 Ignition
The M-34c second stage motor fires to begin a 102-second burn.
T+04:27 Stage 2 Burnout
The Epsilon's M-34c second stage burns out after reaching a velocity of 11,400 mph at a downrange distance of 257 miles east of the launch site. The Epsilon rocket enters a 6-minute coast period.
T+10:24 Stage 2 Separation
The Epsilon's second and third stages separate ahead of third stage ignition.
T+10:28 Stage 3 Ignition
The rocket's KM-V2b third stage motor ignites to begin an 89-second burn.
T+11:57 Stage 3 Burnout
The third stage consumes its supply of solid propellant as the Epsilon rocket begins another coast over the Pacific Ocean.
T+16:48 Stage 3 Separation
The third stage solid rocket motor separates from the Epsilon rocket's liquid-fueled fourth stage, which is called the Post Boost Stage, or PBS.
T+19:08 PBS First Ignition
The Post Boost Stage ignites for a nearly 11-minute burn as the rocket flies just southwest of Hawaii.
T+29:58 PBS First Shutdown
The Post Boost Stage thrusters turn off after reaching a parking orbit.
T+53:50 PBS Second Ignition
The Post Boost Stage reignites to place the SPRINT-A spacecraft in the proper orbit for deployment.
T+60:30 PBS Second Shutdown
The Post Boost Stage shuts down after reaching a planned orbit with a low point of 950 kilometers, or 590 miles, a high point of 1,150 kilometers, or 714 miles, and an inclination of 31 degrees.
T+61:40 SPRINT-A Separation
The 767-pound SPRINT-A planetary telescope separates from the Epsilon rocket as it flies over southern Brazil to begin a one-year mission.
