Many years ago, there was a competition between different countries for space exploration. Meanwhile, with the landing of man on the moon on July 20, 1969, the United States was able to take the lead among these countries. The biggest problem with space exploration is that it costs a lot of money. For example, in 1969, the moon landing cost about $ 25.4 billion. Various private companies have also come forward to find a solution to this problem. Among these companies, SpaceX and blue origin have a special place. For example, when a space shuttle was used, it cost about $ 54,500 to transport 1kg into space. Space x’s falcon 9 rocket currently costs as little as $ 2,720 to launch 1kg into space. So this article will give you a better idea about New Shepard vs Falcon 9.
How Falcon 9 and the new Shepherd work
There is a big difference between these two rockets when comparing the falcon9 rocket with the blue origin company’s New Shepard rocket. For that reason, it is important to first focus on how these two rockets work.
For years, SpaceX has been trying to launch a rocket and land it gently after the launch. As a result of those efforts, they developed a reusable Falcon9 rocket. The falcon9 is the world’s first orbital-class reusable rocket. The Falcon 9 rocket can be used for many purposes such as transporting goods to the international space station, launching satellites, and transporting missions.
There are two main parts to this, stage 1 and stage 2. They use their own merlin engines for both stages. Those engines are powered by liquid oxygen and RP-1. Also, the first stage has 9 merlin engines and one merlin vacuum engine in the second stage. falcon9 produces more than 1.7 million pounds of thrust at sea level.
About 158 seconds after the launch of Falcon 9, the first stage separates from the second stage and returns to Earth. Meanwhile, using its RCS thrusters and grid fins, the rocket corrects its path and reaches the landing pad. Then one merlin engine makes a suicide burn and lands on the landing pad or drone ship. So this is simply how the falcon 9 rocket works. read more about falcon 9 here.
- cost per launch: New US$62 million (2020), Reused: US$50 million
- Function: Orbital launch vehicle
- Height: 70 m (230 ft)
- Diameter: 3.7 m (12 ft
- Mass: 549,054 kg
- Stages: 2
Basically, the new Shepard is not an orbital rocket. This rocket only carries a manned capsule to the Kármán line through a ballistic trajectory. The new Shepard also has the ability to take off vertically and land back vertically. The capsule can carry up to 6 tourists and they can experience a few minutes of weightlessness in microgravity. At the same time, they will be able to observe the Earth from near space.
This rocket uses a BE-3 engine manufactured by blue origin itself. They use liquid oxygen and liquid hydrogen for these BE-3 engines. However, it cannot carry a large payload.
- Function: Suborbital booster
- Height: 18.288 m(60 ft)
- Diameter: ~3m
- Stages: 1
New Shepard vs Falcon 9
These two rockets are completely different and designed for completely different purposes. The blue origin booster is designed to carry a single crew capsule to the Kármán line. But falcon 9 has the ability to transfer a payload to an orbit.
The new Shepard does two engine burns to complete its journey. It is for launch and landing only. But falcon 9 mainly does 3 engine burns. They are launch, re-entry burn, and landing burn.
The new Shepard engine has the ability to throttle deeper than the falcon 9. The main advantage is that the new Shepard can hover near the landing pad.
- Falcon 9 can throttle from about 65% to 100%
- New Shepard can throttle down to at least 40%
Falcon 9 has no hover capability. Therefore, the velocity of the rocket should be 0 at the moment when the landing legs of the falcon 9 touch the ground. So it has the ability to land without hovering. For that reason, it takes a very small amount of fuel to land the Falcon 9 rocket. This landing method is also known as suicide burn.
The falcon9 rocket can produce 1,530,000 pounds of thrust at sea level. But one be-3 engine in a Shepard can produce 110,000 pounds of thrust.
