NOTICE: Yes, I am aware about what's going on in Ukraine right now, and how the prospect of a spaceship built via a collaboration of the West and Russia seems laughably implausible. Thing is, this post was last updated on 21 May 2021, well before the invasion begun, and therefore does not discuss what happened to Ukraine or Russia, nor it is intended to support neither current regimes, instead focusing on the spaceship, its construction effort and details.

Overview

The CARJE is an enormous colony ship built through an international collaboration of the United States (NASA), Russia (Roscosmos), Europe (ESA), Canada (CSA), and Japan (JAXA). Its four segments can be detached and re-attached to the station, as the segments can be controlled by themselves and are not dependent on the ship's cockpit. Each segment is powered by a module with motors and thrusters. The total building cost of the ship is US$10 trillion.

History

After the major success of the ISS and the Lunar Gateway in the past decade, on 2148, NASA, ESA, CSA, and JAXA began development of the largest and most expensive thing ever built with help from SpaceX through the use of modified Starships. The project was named the CAJE (Canada America Japan Europe) Colony Ship, and the estimated cost was of US$7 trillion. However, they deemed the project to be too expensive for them to build by themselves; another major space power was needed.

Roscosmos, whom landed the first humans on Titan on 2064, volunteered themselves to participate in the project. They have built the Podsolnechnik (Подсолнечник, Sunflower), a miniature Bernal sphere designed as a space habitat to be placed on polar orbit. The sphere was modified so as in order to be capable of attaching to the colony ship. The ship was renamed CARJE (Canada America Russia Japan Europe) Colony Ship. After decades of construction and trillions of money spent, the spaceship was finally finished in 2203.

Structure

CARJE is composed of 974 modules, 1424 cargo slots and generates a total of 9093 power units. There are several maneuverable modules all around the ship in order to move it around. Its segments are:

Russian segment (Podsolnechnik)

The Podsolnechnik is from where the spaceship is piloted. A cockpit was added on its top as it was attached to the top of the spaceship. A large rotating torus is attached to the sphere that generates artificial gravity, and the sphere itself is surrounded by ADS Sensor Wings, Large Solar Panels and CSgt Nuclear Generators.

On the cockpit section named "Gagarin" after the first person to journey into outer space, two modified Soyuz spacecraft were attached as escape pods. At the front, two Space Telescopes were attached for better observation of what is in the front of the spaceship.

American-Canadian segment (Friendship)

Friendship is arguably the most important segment when it comes to planetary exploration outside of the spaceship. Constructed by NASA and CSA, it has several crewed spacecraft, including two Space Shuttles that can be detached to explore the planets more easier. There are also four landers (Lunar Modules) to land on the landable planets.

In the middle of the module, there is a hospital named "Jenner" (after the creator of vaccines) to treat sick or injured astronauts. This hospital is considered the best one constructed by mankind. It also has several solar panels and CSgt Nuclear Generators, and two large refuelling sections with 18 Station Refuel Silos and 4 Refuel Modules each so as in order to provide fuel to the spacecraft.

European segment (Columbus)

Named after the Italian explorer, this segment is mostly focused on power production and refuelling. It contains a large number of ATVs filled with batteries, and also a large number of Station Refuel Silos, though their fuel is partially consumed by the fuel cells attached below them.

Like all other modules, it is attached with several MSS Sensor Modules, however Columbus has a rather unique arrangement of those modules, as seen in the blueprint. Several experiments within the vacuum are conducted in the gap between the sensor modules.

Japanese segment (Yume)

Yume (夢, dream) the fourth and last segment of the CARJE, was constructed by JAXA and has a distinct appearance. With lots of uniquely attached solar panels, this part has no CSgt nuclear generators unlike all other parts.

Like Podsolnechnik, Yume also has a rotating ring that generates artificial gravity. The upper solar panel section of the spaceship is directly attached to the rotating ring. On the bottom of the segment there is a large cone-like structure with windows that help crew members see what is behind the spaceship. Though the four upper structures are not physically connected to Yume, they are magnetically locked to the segment, meaning if Yume is detached, the structures will follow it like it was connected to the segment.
