Eros, the site of the protomolecule experiment, in "The Expanse" TV series

Eros is the second-largest near-Earth asteroid located in the inner Asteroid Belt with dimensions of about 34 km × 11 km × 11 km, giving it an irregular, potato-like shape. It's notable as the first asteroid discovered to cross Mars' orbit, and it has been visited by NASA's NEAR Shoemaker probe in 2000, which orbited and landed on it, providing detailed images and data about its surface composition, primarily silicates and metals.

In the universe of The Expanse TV series – a gripping political hard sci-fi drama set in the mid-24th century, where humanity has colonized the entire Solar System – Eros hosts Eros Station, one of the earliest and most bustling outposts in the Belt. It's a major hub for shipbuilding, repairs, and entertainment, with a population of around 100'000 people. The station is spun up to create artificial gravity through centrifugal force, with levels built so that "down" is toward the outer hull, providing about 0.3g – enough for comfortable walking but still a challenge for Inners unused to it.

Unlike the more industrial Ceres, Eros is known for its lower docking fees and vibrant underbelly, featuring casinos, brothels, and shooting galleries that attract crews looking to blow off steam after long hauls. It's described as the "birthplace of the Belt," where early colonists turned raw ore into the skeletons of the first spaceships, though over time, much of the heavy shipping shifted elsewhere. The docks are clustered in five main areas, with old shipyards jutting out like massive spiderwebs of steel and carbon lace, dotted with warning lights and sensors.

Eros plays a central and tragic role in the early story of The Expanse, particularly as the site of the infamous Eros Incident. Security on the station was initially handled by Protogen, but they pulled out and installed a puppet firm to oversee operations. This was all a setup for a massive experiment with the alien protomolecule, which was unleashed on the population as a weapon test, leading to horrifying mutations and the station's eventual takeover by the entity.

Here are some shots of Eros and Eros Station exteriors from the show:

You woke alone in a Martian base.. only to discover you are not quite alone..

Moons of Madness is a first-person cosmic horror adventure game released in 2019. Set in a near-futuristic Martian research outpost, the game blends hard science fiction with Lovecraftian horror, drawing inspiration from works like The Martian and H.P. Lovecraft’s mythos. The narrative follows Shane Newehart, an engineer tasked with maintaining the outpost until a relief team arrives on the transport ship Cyrano. The game’s depiction of the Martian outpost and its pervasive atmosphere of loneliness and abandonment are central to its immersive, unsettling experience.

The Martian outpost, Trailblazer Alpha, is a meticulously designed, state-of-the-art research facility built by the Orochi corporation to investigate a mysterious signal of intelligent origin detected from Mars. The outpost is a believable blend of scientific realism and eerie desolation, featuring functional areas like a greenhouse, infirmary, research labs, and solar panel arrays, all inspired by real-world Mars mission planning. The environment is detailed with personal touches – photo frames, workstations, coffee machines, and sticky notes – that evoke a sense of lived-in habitation, contrasting sharply with the growing sense of decay and neglect. As Shane navigates the base, he encounters malfunctioning systems, such as a flooded greenhouse filled with strange mist, Martian dust leaking into the infirmary, and alien-like, tentacle-covered vines sprawling across corridors, hinting at an otherworldly presence. The stark, rust-colored Martian landscape outside, with its dust clouds and desolate vistas, amplifies the outpost’s isolation, while the interior’s claustrophobic corridors and flickering lights enhance the feeling of being trapped in a failing, abandoned structure.

Shane, with limited security clearance, is unaware of the outpost’s true purpose and isolated from the broader mission, fostering a sense of disconnection from his colleagues and the world. His team’s absence – unexplained as they fail to return from an EVA mission – deepens this solitude, leaving him to face the outpost’s breakdowns alone. The narrative introduces psychological horror through Shane’s hallucinations and visions, possibly tied to his mother’s mysterious disappearance and his own fragile mental state, blurring the line between reality and madness. Cryptic messages, such as “They Never Turn Away!” scrawled on bulletin boards, and encounters with eerie entities like the “Thing in the Mist” intensify the feeling of being watched yet utterly alone. The outpost’s gradual transformation, with alien growths overtaking its once-functional spaces, mirrors Shane’s descent into isolation, as the environment itself seems to reject human presence.

The game’s pacing reinforces these themes, starting with routine tasks like aligning solar panels or repairing rovers, which ground players in Shane’s solitary duties, before escalating into survival against supernatural threats. The lack of combat mechanics heightens vulnerability, forcing players to confront the outpost’s dangers with only their wits, further emphasizing helplessness. While the story’s later plot twists – such as the revelation of Martian technology stabilizing the moons Phobos and Deimos as dormant elder gods – can feel disjointed, the atmosphere of loneliness and abandonment remains consistent, making Trailblazer Alpha a haunting stage for Shane’s unraveling psyche.

Here is a collection of images from the game, focusing on depiction of the Martian base:

Lovell city on the Moon in "The Expanse" TV series - concept art by Lee Fitzgerald

After the bombardment of Earth Lovell City on Luna (the Moon) became the de facto capital of United Nations, one of the three competing powers in universe of The Expanse TV series - a political sci-fi drama set a few centuries in the future where humans have colonized the entire Solar system. Luna functions as a way station between Earth and the rest of the Solar system, and its spaceport at Lovell City serves as a natural meeting place between residents of the inner planets and Belters. Due to its lower gravity, Luna is the only body in the inner system that Belters can easily visit. UN citizens living on Luna are generally wealthier than most of their counterparts on Earth.

Here is a collection of concept art for the Lovell city by Canadian designer Lee Fitzgerald:

The colonization of Mars in "The Martian Chronicles" (1980) TV series

The Martian Chronicles is a 1980 television 3-episode miniseries based on Ray Bradbury's 1950 science fiction novel with the same name The Martian Chronicles which was originally not written as a singular work but as short stories published separately in late 1940s.

The novel and TV series chronicles the exploration and settlement of Mars, the home of indigenous Martians, at the beginning of 21st century when human settlers leave the troubled Earth that is eventually devastated by a nuclear war. The series depicts Mars as having a "thin atmosphere" which humans can breathe, with desert-like vegetation and water-filled canals, cities and other alien structures built by the indigenous Martians thousands of years ago.

The Martian Chronicles TV series, aired on 1980, is one of the few works of science fiction to depict Mars, in the period between the initial Mars enthusiasm that ended in the 1960s, characterized by fear of hostile Martians, and the revival of Mars-related science fiction in the 2000s already without the Martians.

The Martian Chronicles are divided into three parts / episodes:

1. The Expeditions - the exploration of Mars begins with two failed expeditions. Colonel Wilder then leads a 3rd crew to discover the secret of Mars - only to find all the Martians dead from chicken pox.
2. The Settlers - with native Martians wiped out by disease, thousands of humans now colonize the red planet and attempt to create a second Earth.
3. The Martians - with Earth destroyed in a nuclear war, there are only a few survivors on Mars, including Wilder's family. To rebuild what he has lost, Wilder chooses to make Mars his new home.

Here is a collection of screenshots from the series. Keep in mind that the series is from 1980 and the creators were trying to replicate the retrofuturistic style of the illustrations from an even older novel from 1950.

A long night on Mars in "Fort Solis" thriller game

Fort Solis (2023) is a cinematic narrative-driven science fiction thriller game set in 2080 on Mars. During a night engulfed in a severe sandstorm two mining engineers, Jack and Jessica, respond to an unusual emergency alert from a mining and research station "Fort Solis". The station is on lockdown and seems to be abandoned. The pair separately starts to investigate, what has happened in the base, searching for clues throughout the claustrophobic buildings. Piece by piece they unlock both the various parts of the base and the truth behind recent events there. The game starts as a detective and ends as a thriller.

Fort Solis runs on Unreal Engine 5.2 so visually it is really good, especially the character models and animations. The game is not long, you can finish it in 5 to 8 hours even when reading, watching and listening to all of the clues throughout the base. The story will unfold linearly piece by piece, but there are two separate endings possible in the final act of the game.

Pallas, the origin of the Free Navy, in "The Expanse" TV series

Pallas, located in the Main Asteroid Belt between the orbits of Mars and Jupiter, is the third-largest asteroid in the Solar System (~512km in diameter). It has 22% the mass of Ceres, the largest asteroid in the Solar System, and gravity of 0.021g (2,1% of the gravity force on Earth). With an orbital inclination of 34.8°, Pallas's orbit is unusually highly inclined to the plane of the Asteroid Belt, making Pallas harder to reach by spacecraft.

In the universe of The Expanse TV series (a political sci-fi drama set in mid-24th century when humans have colonized the entire Solar system) Pallas hosts one of the oldest stations, Pallas Station, in the outer planets, refinement stations for the mining operations in the Asteroid Belt and the largest fuel refinery in the Belt.

In The Expanse TV series Pallas has a population of 9 to 13 thousand, but is also known for its extremist Belter splinter groups among its colony. One of those splinter groups eventually form the core of the Free Navy. Pallas is the birthplace of Marco Inaros, Naomi Nagata and their son Filip.

In late season 5 of the show the acting Secretary-General of the United Nations David Paster orders an uncoordinated missile strike against the Pallas Station, destroying one of its habitation rings and killing thousands of Belters.

Here you can view some of the few shots of Pallas Station exteriors in the show:

Destruction of Deimos in "The Expanse" TV series

Deimos is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos, likely an asteroid captured by Mars' gravity, is highly non-spherical with a mean diameter of 12.5 km (about 57% the size of Phobos) and it orbits 23,460 km from Mars (Deimos' orbit is slowly getting larger and it is expected to eventually escape Mars' gravity). Escape velocity from the surface of Deimos is only 5.6 m/s so a human can basically jump off of it.

In the universe of The Expanse TV series (a political sci-fi drama set in mid-24th century when humans have colonized the entire Solar system) Deimos hosts military facilities and a deep radar station for Martian Congressional Republic - one of the three competing powers in The Expanse, along with the United Nations (based on Earth) and the Belt.

In early season 2 of The Expanse Deimos is destroyed with nuclear missiles in a "moon for a moon" retaliatory strike by the United Nations (Earth) after the Martian assault cruiser destroyed Earth's research base on Saturn's moon Phoebe along with the consequent destruction of the moon itself. The destruction of Deimos killed 17 Martians and the moon disintegrated forming the "Deimos Ring" around Mars.

How to steal an asteroid .. "For All Mankind" season 4

It's possible our judgement is biased towards Mars-related content, but season 4 of For All Mankind alternate history sci-fi TV series is show's most exciting season yet. In season 4, depicting the alternate 2003, the international Happy Valley Base, founded in 1995 during season 3, has been significantly expanded and there are around 200 people living in it. We made a separate article with a large collection of high resolution shots depicting the exterior and interior of Happy Valley Base:

Mars base for 200 people in For All Mankind season 4

The main theme in season 4 is increasingly diverging visions for the purpose of human presence on Mars. For some it's only another contract job, but for others Mars is a new place to call "home". Add to the mix a once-in-a-lifetime opportunity to get hold on a large lithium-rich asteroid and increasingly strained relationships between the "upper class" (astronauts / cosmonauts, scientists and top executives) and contract workers literally living underground, and you have a recipe for a "Martian rebellion".

For All Mankind is exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon and the intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show: in season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole; in season 2 (1983) both bases have been expanded and the superpowers compete for resources on the Lunar surface; in season 3 (1992 to 1995), Soviets and US are joined by a private company Helios and North Korea for a four way race to be first on Mars; in season 4 (2003) there is a sprawling international human base on Mars and an unexpected side enters the race to get hold on a large, lithium-rich asteroid for mining. You can watch the show on Apple TV+

Mars base for 200 people in "For All Mankind" season 4

Season 4 of For All Mankind alternate history sci-fi TV series, depicting alternate 2003, "is really about the building of a new civilization on Mars" by the words of the co-creator of the series Ben Nedivi. The international Happy Valley Base, founded in 1995 during season 3 and located in Melas Chasma in the Valles Marineris canyon system on Mars, has been significantly expanded and there are around 200 people living in the base during season 4. The base is financed and operated by Mars-7 Alliance (consisting of US, USSR, ESA, North Korea, India, Japan, and the Coalition of Communist Countries for Spaceflight (CCCS)) and maintained by a private company Helios Aerospace.

Ground level of the base features several separate facilities for power generation, communications, fuel refinement, regolith processing, algae production, storage etc. and a central interconnected cluster of modules consisting of the Entrance hall for new arrivals with airlocks for the rovers, control rooms, laboratories, hydroponic farms, meeting rooms, warehouses / garages, a cafeteria, as well as the quarters for higher level personnel and astronauts / cosmonauts. The base has 5 underground sublevels, of which level 4 & 5 are still under construction in 2003 and not accessible. The sublevels house maintenance and storage rooms and additional quarters for workers. There is also a separate North Korean sector accessible only to North Koreans. The base also operates six landing pads for their orbital Hopper shuttles.

The design of the Happy Valley Base in For All Mankind is the most plausible design of a mid-sized human base on Mars that we have ever seen in a TV series or film.

For All Mankind is exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon and the intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show: in season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole; in season 2 (1983) both bases have been expanded and the superpowers compete for resources on the Lunar surface; in season 3 (1992 to 1995), Soviets and US are joined by a private company Helios and North Korea for a four way race to be first on Mars; in season 4 (2003) there is a sprawling international human base on Mars and an unexpected side enters the race to get hold on a large, lithium-rich asteroid for mining.

Ganymede, the breadbasket of the Belt, in "The Expanse" TV series

Ganymede is one of the "Galilean moons" of Jupiter and the largest moon in the Solar System. It's only slightly smaller than Mars, but with only half the density, its gravity is actually weaker than the Moon's. Ganymede is the only moon with any magnetosphere thus having the ability to deflect charged ionizing radiation. In the universe of The Expanse TV series (a political sci-fi drama set in mid-24th century when humans have colonized the entire Solar system) Ganymede acts as the breadbasket of the Belt - one of the three competing powers in The Expanse, along with the United Nations (based on Earth) and Mars.

In the universe of The Expanse Ganymede has millions of residents and Ganymede Station was one of the first permanent human settlements in the outer planets, built as a long term colony with large domes filled with food crops. Large mirrors were placed around the moon to supply the Sun's light to the surface for crop growth. It was known as the safest station in the Jovian system, and many humans from other colonies traveled to Ganymede to deliver their babies, as the magnetosphere helps claim the Jovian moon the lowest amount of birth defects and stillbirths. Initially, at the start of the series, Ganymede is divided between the United Nations and Mars.

The life on Ganymede is depicted in season 2 of The Expanse. Here you can view some of the best shots from Ganymede (downscaled from 4K UHD screens for better image quality) as well as some concept art for it.

Building a new civilization on Mars in "For All Mankind" season 4

Yesterday Apple TV+ released yet another video revealing more details about the upcoming season 4 of For All Mankind alternate history sci-fi TV series. As the co-creator of the series Ben Nedivi states in this featurette: "This season is really about the building of a new civilization on Mars. Last year in season 3 you saw the first explorers arrive on Mars. This season you're actually seeing hundreds of people up there and you're seeing, how civilization becomes civilization".

Judging from the reviews by journalists who were given early access to the first 7 episodes of season 4, this season might be the show's most exciting season yet. We look forward to judging it for ourselves. Season 4 premieres November 10 on Apple TV+, with episodes releasing weekly.



Some of the details for season 4 were previously revealed in a teaser and a trailer.

For All Mankind is exploring the idea of never ending space race if Soviets would have beaten US in the race for the Moon and the intention of the show is each season to jump about a decade further into the increasingly diverging reality of the show: in season 1, depicting alternate 1969 to 1974, both Soviets and US start building their separate bases near the lunar South pole; in season 2 (1983) both bases have been expanded and the superpowers compete for resources on the Lunar surface; in season 3 (1992 to 1995), Soviets and US are joined by a private company Helios and North Korea for a four way race to establish the first human base on Mars.

Here are some HD images from the featurette above.
