|The PSLV's solid-fueled first stage motor ignites when the countdown clock reaches zero.
|Ground-lit Booster Ignition
|Four of the PSLV's six strap-on boosters ignite in pairs two-tenths of a second apart at T+plus 0.46 seconds and T+plus 0.66 seconds to push the 146-foot-tall rocket off the pad atop 1.7 million pounds of thrust.
|Air-lit Booster Ignition
|Two more 39-foot-long strap-on motors ignite at an altitude of nearly 8,800 feet to give the PSLV an extra boost.
|Ground-lit Booster Separation
|The PSLV's four ground-lit boosters burn out and jettison, leaving the first stage and two air-lit boosters to continue firing.
|Air-lit Booster Separation
|The PSLV's two air-lit boosters burn out and jettison at an altitude of more than 24 miles.
|First Stage Separation/Second Stage Ignition
|Flying at an altitude of nearly 36 miles, the PSLV's solid-fueled first stage burns out and separates after consuming more than 300,000 pounds of propellant. The PSLV's Vikas second stage engine ignites less than a second later.
|The PSLV initiates closed-loop guidance.
|Payload Fairing Jettison
|The 3.2-meter, or 10.5-foot, diameter aluminum payload fairing jettisons once the PSLV flys above the dense lower atmosphere, exposing the Mars orbiter to space.
|Second Stage Separation
|The PSLV's Vikas engine shuts down and the second stage separates at the conclusion of its burn at an altitude of 82 miles.
|Third Stage Ignition
|The PSLV's third stage solid-fueled motor begins a 112-second burn.
|Third Stage Separation
|The PSLV's third stage separates from the fourth stage, beginning a 25-minute coast period before the fourth stage fires to complete the powered phase of the launch.
|Fourth Stage Ignition
|The PSLV's fourth stage, powered by two hydrazine-fueled engines, ignites to propel the Mars orbiter into an elliptical transfer orbit. The burn will last 8 minutes, 39 seconds.
|Fourth Stage Shutdown
|The fourth stage shuts down after achieving an orbit with a perigee of 155 miles, an apogee of 14,602 miles and an inclination of 19.2 degrees.
|The PSLV fourth stage deploys the Mars Orbiter Mission spacecraft.
