As humanity’s gaze turns towards the stars, one name stands at the forefront of the space exploration revolution: Elon Musk‘s SpaceX.

Among its many ambitious projects, the SpaceX Starship promises to reshape our understanding of interplanetary travel.

This colossal 9-meter diameter rocket has captured our imagination with the grand vision of shuttling thousands of people on a six-month journey to Mars.

But what lies within this futuristic vessel? What can we expect from the spaceship interior that aims to make long-duration space travel a reality?

Historically, our mental image of a spacecraft has often been based on cramped capsules, such as the iconic Apollo 11, Soyuz, or Dragon. These designs, while functional, have offered little in the way of comfort.

Even modern incarnations like the Orion spacecraft still lack the headroom to stand upright inside the Command Module. With its larger size, the space shuttle hinted at more livable conditions, but it still fell short of providing ample space for extended journeys.

Enter the SpaceX Starship—a towering, 9-meter diameter rocket that evokes images of Flash Gordon’s futuristic transport. Elon Musk’s vision of a vessel capable of shuttling thousands to Mars within six months is a compelling proposition.

However, spending half a year in the confined space of a metal box hurtling through an interplanetary void is daunting, even if the box is quite spacious.

As we anticipate the Starship interior, our expectations are high, and speculation runs rampant about what life onboard might entail.

The Starship Interior

The potential Starship interior draws inspiration from other spaceship interiors.

Iconic spaceships like the Enterprise from “Star Trek” boasted luxurious living quarters for its crew, providing them with comfort during multi-year galactic treks.

On the other end, the Millennium Falcon envisioned a pragmatic mix of tubes and cabins that suited a spacefaring pirate.

The SpaceX Starship interior aims to strike a balance, offering more comfort than its predecessors while acknowledging the constraints of space travel.

While not luxurious, it aspires to provide adequate room and amenities for the journey to Mars and back.

1. Crew Size

One critical aspect that shapes the interior is the choice of crew size. This decision hinges on resource allocation, as each crew member requires sustenance and life support.

With a maximum load capacity of around 100 metric tons, the mass of each individual becomes a crucial factor. Equally significant is the psychological well-being of the crew during long-duration interplanetary missions.

Experts largely converge on a crew size of around 10 for a Mars mission, balancing resource utilization and crew morale. Despite Musk’s suggestion of sending a hundred people, practical considerations rule out such a large contingent.

2. Floor Layout

The Starship’s dimensions—50 meters in length by 9 meters in diameter—offer ample space for functional zones.

The lower portion is reserved for the essential rocket components, including up to nine Raptor engines.

These engines are split between sea-level and vacuum configurations, crucial for landing and interplanetary travel. Above this section, the spacecraft houses massive propellant tanks capped by a common dome.

The cargo and crew quarters occupy the upper section, estimated at around 17 meters in length.

A logical division into six vertical levels is envisioned, with varied ceiling heights depending on the function of each space.

With approximately 2.5 meters from floor to ceiling, the interior aims for comfort without impeding movement. The center of gravity remains low, vital for successful vertical landings on Mars.

3. Levels 1 & 2

The layout projection suggests the lowest level will house the cargo bay, storing resources and infrastructure for survival on Mars, including rovers and life support systems.

The second level is poised for essential supplies, potentially even featuring a hydroponic garden for cultivating fresh produce like leafy greens.

4. Level 3

On the third level, a gym and bathroom facilities are anticipated. Physical fitness is essential for extended microgravity stays. For example, the International Space Station’s astronauts spend hours daily exercising, combining cardio and resistance training.

Though the mechanics of traditional weightlifting won’t apply, innovative resistance machines can maintain muscle mass and bone density.

In the absence of showers, astronauts resort to wet towels and dry shampoo—a practice likely to continue aboard the Starship. Notably, this level will also feature the much-discussed space toilet, a crucial component of long-duration space travel.

5. Level 4 & 5

Moving upwards, the fourth level likely contains crew quarters. While not luxurious, ample volume should allow for reasonably sized compartments, perhaps arranged vertically.

Level five could function as a communal area, providing a space for floating, relaxing, and offering a panoramic view through a large window.

6. Level 6

The final level, constrained by the tapering ship structure, best suits the command deck. Here, the crew would strap into their seats for launch and landing, with essential flight controls and instruments.

7. The Central Column

Connecting all levels is a central column facilitating travel in zero gravity, also serving as a conduit for plumbing and wiring. However, maintaining contact with Earth as the ship journeys into interplanetary space is the true challenge.

Communication delays grow until real-time conversations become impossible. Psychological isolation looms as crew members grapple with the isolation, starkly contrasting our hyper-connected world.

8. Energy

One critical aspect underpinning the Starship’s functionality is energy generation and distribution. Solar panels offer a logical solution, as the International Space Station exemplifies.

However, the immense scale of these arrays presents deployment challenges.

Alternative options include harnessing hydrogen fuel cells or utilizing advanced battery technology. Each has its own merits and drawbacks, considering factors such as weight, efficiency, and scalability.

Does Starship have an interior?

Yes, SpaceX’s Starship has an interior, though its design and layout depend on the specific mission profile it’s being configured for.

How many seats will Starship have?

It is designed to eventually carry up to 100 passengers. However, the exact number of seats and configuration could vary depending on the specific mission and design iteration.

The Starship is a highly adaptable platform intended for a range of missions, from satellite deployment to Mars colonization.

Therefore, the seating capacity might change based on the specific requirements of each mission, such as cargo capacity, distance, duration, and the level of comfort required.

Keep in mind that SpaceX is continuously evolving its designs, so the most current information might differ from what was known in early 2023.

How much does Starship carry?

The Starship is designed to carry more than 100 metric tons (220,462 pounds) to Earth orbit. This capacity positions it as one of the most powerful launch vehicles in terms of payload capacity, potentially surpassing even the Saturn V rocket used in the Apollo missions.

The Starship is being developed to support a wide range of missions, including crewed missions to the Moon, Mars, and other destinations in the solar system.

How many floors does Starship have?

For missions such as crewed spaceflights to the Moon or Mars, Starship is expected to have several floors to accommodate crew living quarters, cargo areas, and possibly research facilities.

However, the specific number of floors and their layout may differ based on mission requirements and ongoing design refinements by SpaceX.

Conclusion

Intriguingly, while speculation rises, the design of the SpaceX Starship interior remains uncertain. As humanity edges closer to the era of interplanetary travel, envisioning life within these metal walls stirs curiosity and anticipation.

What will it truly be like to inhabit this amazing spaceship during a six-month journey to Mars and beyond? As we venture into the cosmos, only time will reveal the reality of life inside the Starship.

  1. Nice article but my mind is obsessed with a space-x zero g space station. Particularly, a concept of taking a one-way tanker where the infrastructure Skelton of floors and walls are pre built inside the fuel tanks. Once the tanks are offloaded to orbital storage, a crew moves in and cuts open the tanks for central tube access. Using the plugin wall modules concept the Chinese use on their space station it could be quickly fleshed out from a cargo ship.

  2. The fact that Roberts Space Industries has been completely ripped off here is Absolutely insane. the stanton system has long been adorned with the beauty of the constellation phoenix which elon muskrat is clearly angry about. long live our lord chris roberts and love live the Constellation phoenix. one day that hot tub will work.

  3. Oh dear. Why have you used a screenshot from the video game Star Citizen to headline this article when you had all those other lovely images to use? Tsk.

    Also, why is this text box capitalizing every word?
