SpaceX’s Main Rockets
SpaceX has three main spacefaring vehicles. SpaceX is also the only space program
that uses reusable rockets. With their unique technology they plan to cut the cost of sending
things to space. The main rockets are:
Falcon 9:
The Falcon 9
is a two stage
rocket. It is the first
orbital class rocket
that can be reused.
It has nine first
stage engines called
the Merlin Engines.
The whole rocket is
70 meters (229.6
feet) tall. It is 3.7
meters (12 feet) in
diameter. It weighs
a whopping 549,054
kilograms
(1,207,920 pounds).
The Falcon 9’s payload usually consists of the Dragon (more will be covered later in the
article). The Falcon 9 has a pressurized and unpressurized trunk. Later when SpaceX is
capable to go to Mars, the Falcon 9 will carry the Dragon to Space with the astronauts in the
pressurized trunk of the Dragon. The same will be done if SpaceX wants to go to the moon.
Falcon Heavy:
The Falcon Heavy is SpaceX’s biggest rocket. It is also the most powerful operational
rocket in the world. It can lift more than twice the payload of the next closest operation vehicle. It
is capable of generating around 64 metric tons (141,000 pounds). That is more mass that a 737
airplane filled with passengers, luggage, and fuel.
The Falcon Heavy 70 meters (229.6 feet) tall. It is 12.2 meters (39.9 feet) wide. It weighs
1,420,788 kg (3,125,735 pounds). At sea level it can produce 22,819 kN (5,130,000 lbf) of
thrust. In the vacuum of space it can create 24,681 kN (5,548,500 lbf) of thrust.
The Dragon:
The Dragon is a free-flying spacecraft. It is designed to carry cargo and people to
orbiting destinations. SpaceX made history in 2012 when they used the Dragon to deliver a
payload to the ISS and safely return cargo to Earth. They were the first commercial company to
do this. Currently, the Dragon on carries cargo to space, however it was designed to carry
humans. The first test to fly humans inside of the Dragon is scheduled for January of 2019.
The Dragon is 7.2 meters (23.6 feet) tall. It is 3.7 meters (12 feet) in diameter. It can
carry up to 6,000 kg (13,228 pounds) in a 25 square meter (883 square feet) area. It can return
3,000 kg (6614 pounds) in a 11 square meter (388 square feet) area.
