SpaceX, the company run and founded by Tesla Motors’ Elon Musk, has successfully completed a vertical take-off and vertical landing (VTVL) with its Falcon 9 rocket after delivering a payload of commercial satellites, setting a new landmark in space travel technology.
Comparision of Falcon 9 with New Shepard
About Falcon 9:
Two stages of Falcon 9:
FIRST STAGE: Falcon 9’s first stage incorporates nine Merlin engines and aluminum-lithium alloy tanks containing liquid oxygen and rocket-grade kerosene (RP-1) propellant. After ignition, a hold-before-release system ensures that all engines are verified for full-thrust performance before the rocket is released for flight. Then, with thrust greater than five 747s at full power, the Merlin engines launch the rocket to space. Unlike airplanes, a rocket's thrust actually increases with altitude; Falcon 9 generates more than 1.5 million pounds of thrust at sea level but gets up to nearly 1.7 million pounds of thrust in the vacuum of space.. The first stage engines are gradually throttled near the end of first-stage flight to limit launch vehicle acceleration as the rocket’s mass decreases with the burning of fuel.
SECOND STAGE: The second stage, powered by a single Merlin vacuum engine, delivers Falcon 9’s payload to the desired orbit. The second stage engine ignites a few seconds after stage separation, and can be restarted multiple times to place multiple payloads into different orbits. For maximum reliability, the second stage has redundant igniter systems. Like the first stage, the second stage is made from a high-strength aluminum-lithium alloy.
