In today's video, we‘ll take a look at how SpaceX’s Starship and other rockets compare. To begin with, what exactly are rockets and starships?
Starships theoretically are large, manned spaceships used for interstellar travel that is meant to take you between two planetary systems. Starship is SpaceX's rocket that's gonna take humans to Mars in the near future.
Whereas the word rocket can mean various things like tall, thin, round vehicles. or a type of engine or a vehicle that uses the engine.
Rockets are mainly used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration. The most common type of high-power rocket is the chemical rocket because they create a high-speed exhaust by the combustion of fuel with an oxidizer.
How do they work?
They work on Newton's principle of the third law of motion which states that for every action, there is an equal and opposite reaction. Rockets also work by action and reaction law. They push forward by expelling their exhaust in the opposite direction at high speed which can therefore work in the space vacuum. Moreover, rockets work more effectively in space than in the earth’s atmosphere. To control their flight, rockets rely on momentum, airfoil, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity.
Rockets use aerospace-grade aluminum or titanium, both metals are very strong but lightweight for the mainframe. However, Carbon composite structures are being researched for future use on mainframes since aluminum melts at high reentry temperatures.
Rockets are made up of four different parts: The structural system also called frame which is similar to the fuselage of an airplane, the payload system of a rocket that depends on the rocket's mission, the guidance system that may include very sophisticated sensors, and the propulsion system that consists of liquid fuel and oxidizers.
The latest rocket today is the Falcon 9 by SpaceX. It is a reusable, two-stage rocket designed and manufactured by SpaceX for reliable and safe transport of people into Earth’s orbit and beyond. It is the world’s first orbital-class reusable rocket. SpaceX is able to refly the most expensive parts of the rocket because of its reusability.
The Saturn V was an expendable rocket NASA built so astronauts could go to the moon (The V in the name is the Roman numeral five.) It was called a Heavy Lift Vehicle because it was a very powerful rocket. This rocket has a lift capacity of 310,000 lb (140,000 kg) to LEO To this date, the Saturn V remains the only launch vehicle that carried humans beyond low Earth orbit. Between December 1968 and December 1972, 24 astronauts were launched to the Moon for the U.S. crewed Apollo missions. . It flew a final time in 1973 with no crew members to launch space station Skylab into Earth’s orbit.NASA later created a second human spaceflight program project called Gemini where the launch system Titan II GLV had a greater thrust-to-weight ratio than the Saturn V.
Other recent US launch vehicles have a lower launch capacity to LEO compared to the Saturn V. The Falcon Heavy vehicle, manufactured by SpaceX, has the maximum payload capacity of 140,700 lb (63,800 kg), the Atlas V 551 has a capacity of 41,478 lb (18,814 kg), the US Delta IV Heavy's capacity is 63,470 lb (28,790 kg), and The European Ariane 5 ES delivers up to 46,000 lb (21,000 kg) and the Russian Proton-M can launch 51,000 lb (23,000 kg).
The Proton-M is an abundant launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965. Even in 2021 modern versions of this launch system are being used which makes it one of the most successful heavy boosters in the history of spaceflight.
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle which is still under development by NASA since 2011. It has successfully replaced the Ares I, Ares V, and Jupiter planned launch vehicles. Like the other canceled proposals, it is a design derived from the components and technology of the earlier Space Shuttle.
The United Launch Alliance's Atlas V rocket was one of the world's most reliable launch vehicles used to deliver exploration spacecraft was, This rocket was used to take satellites and classified payloads into space for NASA, the United States Air Force, the National Reconnaissance Office, and commercial customers. All these rockets mentioned earlier could be reused only a limited number of times, unlike SpaceX's Starship.
Ok, so now that I've told you a lot about Rockets, let's talk about Starship and the big difference it has with rockets! Let’s see the SpaceX Starship update, and why it’s better than other rockets. We made a comparison between SpaceX’s Starship and other space rockets in this short SpaceX documentary.
