NOTE: Times approximate.

T-00:00:00	Launch
Producing 1.6 million pounds of thrust, the Zenit 2FG rocket soars into the sky at 2016 GMT (3:16 p.m. EST) Tuesday from the Baikonur Cosmodrome in Kazakhstan.
T+00:02:29	First Stage Separation
The Zenit rocket's RD-171 engine shuts down and the first stage separates in the upper atmosphere. The second stage's RD-120 engine ignites to continue thrusting toward orbit. The Zenit's payload fairing will be jettisoned during the second stage burn.
T+00:08:30	Second Stage Shutdown
The Zenit's second stage engine shuts down as the Phobos-Grunt spacecraft and its main propulsion unit enter an elliptical low Earth orbit.
T+00:11:24	Spacecraft Separation
The Phobos-Grunt spacecraft and its main propulsion unit separate from the Zenit rocket's second stage in orbit.
T+02:39:45	MDU First Ignition
The spacecraft's main propulsion unit, or MDU, ignites at 2255 GMT (5:55 p.m. EST) for a burn lasting nine-and-a-half minutes to raise the apogee, or high point, of its orbit to an altitude of more than 2,500 miles.
T+02:48:15	MDU First Shutdown
The hydrazine-fueled MDU shuts down at 2305 GMT (6:05 p.m. EST) after reaching a higher orbit.
T+02:50:14	Jettison Tanks
Auxiliary propellant tanks are jettisoned from the Phobos-Grunt propulsion unit.
T+04:46:45	MDU Second Ignition
After coasting through space for two hours, Phobos-Grunt's MDU ignites again at 0102 GMT Wednesday (8:02 p.m. EST Tuesday) to accelerate the spacecraft on an escape trajectory toward Mars.
T+05:04:07	MDU Second Shutdown
Phobos-Grunt reaches an interplanetary trajectory at 0120 GMT Wednesday (8:20 p.m. EST Tuesday) following the second burn of the main propulsion unit. The probe will reach orbit at Mars in October 2012.
