Spaceship vs Rocket: What Are the Main Differences?

Spaceship vs Rocket: Five Must-Know Facts

• Rockets and spaceships are two parts of the same launch process. In other words, rockets help the spaceship reach space.
• The spaceship was invented nearly 30 years after the invention of the rocket.
• Rockets tend to be much cheaper than spaceships. A rocket could cost around $50-60 million, while a spaceship can cost as much as $40-50 billion.
• Spaceships are traditionally reused, while rockets don’t always have to be.
• Rockets are always unmanned, while spaceships can be crewed or uncrewed.

When you think about it, it’s hard to wrap your head around the fact that man has achieved space travel. It’s just an accepted part of our daily lives that mankind successfully managed to go from the surface of the earth to the outer reaches of space. Why pretend that’s not incredible?

To truly appreciate this feat, it’s worth understanding how all the moving parts work. Let’s begin with spaceships and rockets.

Spaceship vs Rocket: Full Comparison

When hearing about the latest NASA launch, there are a lot of unfamiliar words that get tossed around by astronauts and experts alike. It can be difficult to know what it all means without an explanation for those of us who aren’t NASA astronauts.

For instance, what are the similarities and differences between a spaceship and a rocket? What are the features that set them apart from one another?

This article will help outline those similarities and differences and attempt to make some sense of their distinguishing features. We’ll begin with a side-by-side comparison, then look at the similarities and differences after that.

Spaceship vs Rocket: What’s the Difference?

Now that we’ve seen the two compared side-by-side, let’s take a look at the distinguishing features of both spaceships and rockets.

The key difference between Spaceship vs Rocket is rockets take the spaceship up to space and then fall back down to earth once releasing the ship. Spaceships are manned or unmanned but rockets are never manned. Also, rockets have much more power than spaceships.

The space shuttle is known to be very fast. It accelerates to 29,000 kmh. That’s 18,000 miles per hour. Rockets have to reach that speed to be able to leave Earth’s gravitational pull to get into space.

Spaceship: The Complete History

A spaceship — also known as spacecraft — is a vehicle made to transport astronauts to space and allow them to fly throughout the galaxy. Originally deriving their design and their use from satellites, spacecraft are now used for a variety of purposes including observation, meteorology, navigation, exploration, and more. 

While there are countless differences between spaceships from different manufacturers, the average spaceship consists of a handful of key components: Thrusters (a guidance system), a communication system, fuel, and an aeroshell and parachutes.

The thrusters are used to move the spaceship this way or that, but they differ from rockets because they’re much less powerful and don’t fall away from the vehicle. The guidance system helps the spaceship land on a planet or dock at a space station.

The communication system and fuel are pretty self-explanatory; the former helps the astronauts talk back and forth with their mission control, and the latter helps the spaceships’ thrusters. Lastly, the aeroshell and parachutes assist in the spaceship’s re-entry into the earth’s atmosphere so that the astronauts can return home safely.

Spaceships can be crewed, semi-crewed, or uncrewed, but their intent remains the same regardless – to fly in outer space, carry cargo, and make observations. Additionally, spaceships can be sub-orbital or orbital. Sub-orbital spaceships enter space and then come back to the earth’s surface without fully orbiting the earth.

These spaceships are typically recoverable.

Orbital spaceships, on the other hand, enter a full orbit around the planet. These ships are traditionally unrecoverable.

Rocket: The Complete History

The word “rocket” can have several meanings. Beyond space travel rockets, which are used to help lift a launch vehicle or space shuttle out of the atmosphere and toward the stars and planets beyond, rockets can also refer to weapons, fireworks, and even a leafy vegetable. For all intents and purposes, we’ll be discussing space travel rockets.

In essence, a rocket is a projectile that thrusts a spaceship into space. Its design is to expel propellant through the exhaust, propelling massive amounts of thrust toward the ground to push the spacecraft upward at the high speeds necessary to reach space.

Because of the science behind their design, rockets are capable of working in the vacuum of space. Some even work better in space than on earth.

The design of space travel rockets consists of several key components: fuel load, fins, pumps, and the guidance system. The fuel load is what the rocket uses to help the launch vehicle to the high speeds needed to travel to space.

The fins — located at the bottom of the rocket — give the launch vehicle stability, helping to keep the space shuttle on course.

The pumps are the part of the design that physically push the fuel where it needs to be. Lastly, the guidance system sets and maintains the course, allowing both the astronauts and the folks back at NASA to see the rocket’s progress and assess any technical issues. 

Once the rocket helps the launch vehicle reach space, it can officially clock out. In other words, the rocket is then programmed to fall away from the spaceship and return to earth.

While scientists haven’t traditionally cared much about a rocket’s landing as long as it is kept away from civilian harm, there have been several recent advances in landing technology.

These advances include safely landing the rocket back down to earth to be reused or repurposed again.

What’s New With Space X’s Starship Launch

Elon Musk’s SpaceX is embarking on its most audacious mission to date by conducting a global test flight of its massive Starship. The rocket is the largest and most powerful ever constructed, with the ambitious aim of transporting individuals to the moon and Mars.

Starship, which protrudes nearly 400 feet (120 meters) into the South Texas sky, may take off as soon as Monday, without any passengers onboard. Musk’s firm received approval from the Federal Aviation Administration on Friday, April 14th, 2023.

This will be the maiden voyage of Starship’s integrated two components. Earlier versions of the futuristic-looking upper stage had flown several miles into the stratosphere a few years ago and had crashed four times before eventually landing upright in 2021. The immense first-stage rocket booster, named Super Heavy, will take flight for the first time.

Furthermore, the duration of the test flight will be 1 1/2 hours, and it will not complete a full orbit of the Earth. If Starship makes it past the three-minute point following liftoff, the booster will be instructed to detach and plunge into the Gulf of Mexico. The spacecraft will then progress eastward, flying over the Atlantic, Indian, and Pacific Oceans before landing in the vicinity of Hawaii. While Starship is built to be entirely reusable, nothing will be salvaged from the test flight.
