🔥The Delta 4 rocket uses a staggered engine start sequence to mitigate the fireball created by the hydrogen burning.
✈️During flight, the Delta 4 rocket reaches Mach 1 and maximum dynamic pressure.
🚀Boosters are jettisoned to shed weight and increase efficiency.
💡The remaining engine throttles to full power to maximize performance against gravity losses.
🌍The second stage of the Delta 4 rocket carries the payload to its final orbital destination.
What is the purpose of the staggered engine start sequence?
—The staggered engine start sequence is used to mitigate the fireball created by the hydrogen burning and ensure a safe launch.
What is Mach 1?
—Mach 1 is the speed of sound. The Delta 4 rocket reaches Mach 1 during its flight.
Why are boosters jettisoned during the launch?
—Boosters are jettisoned to shed weight and increase the efficiency of the rocket.
Why does the remaining engine throttle to full power?
—The remaining engine throttles to full power to maximize performance against gravity losses.
What is the role of the second stage in the Delta 4 rocket?
—The second stage of the Delta 4 rocket carries the payload to its final orbital destination.
