AFTER #LIFTOFF
One minute and 10 seconds after liftoff, #Falcon 9 reaches supersonic speed.
The vehicle will pass through the area of maximum #aerodynamic#pressure—max Q—roughly 13 seconds later. This is the point when mechanical stress on the #rocket peaks due to a combination of the rocket’s velocity and resistance created by the Earth’s #atmosphere.
Approximately 161 seconds into flight, the first-stage engines are shut down, an event known as main-engine cutoff, or #MECO. At this point, Falcon 9 is 80 kilometers (50 miles) high, traveling at 10 times the speed of sound.
Three seconds after MECO, the first and second stages will separate. One second later, the second stage’s single #Merlin vacuum engine ignites to begin a six-minute burn that brings Falcon 9 and #Dragon into low-Earth orbit.
Forty seconds after second-stage ignition, Dragon’s protective nose cone, which covers Dragon’s berthing mechanism, will be jettisoned.
Nine minutes and 40 seconds after launch, the second-stage engine cuts off (#SECO).
Thirty-five seconds later, Dragon separates from Falcon 9’s second stage and achieves its preliminary orbit. It then deploys its solar arrays, and begins a carefully choreographed series of #Draco thruster firings to reach the space station.
The P-PODs will also be deployed from the second stage following Dragon separation.
