Mars
A frozen frontier where early human colonies watched the Sun dim.
Before Astrophage drained the Sun's energy and crashed the solar grid, Mars held human outposts as part of Earth's biggest expansion beyond home. Rocket's journey rarely crosses this Red Planet directly, but those colonies fell hard alongside Earth when the starlight-eating microbes started their work. The loss of these Martian bases shows how bleak things got, proving no corner of the system stayed safe and leaving the Hail Mary mission as humanity's only desperate shot.

Lore & Background
Mars stands as a testament to human resilience and technological prowess in the era preceding the Astrophage pandemic. Before the solar output began its catastrophic decline, engineers and scientists established habitats on the surface, utilizing advanced life support systems to thrive in the harsh environment. These outposts were intended to be stepping stones for further interplanetary expansion. However, when the Astrophage organisms discovered by Ryland Grace's mission began consuming starlight across the galaxy, Mars was not spared.
The dimming Sun meant that solar power generation became increasingly unreliable, threatening the life support systems of every colony. Unlike Earth, which had more resources to fight for survival initially, Martian settlements were isolated and vulnerable. The planet's inclusion in the lore emphasizes the global nature of the crisis. It was not just an Earth problem but a solar system-wide emergency that necessitated leaving the star entirely. The silence from Mars during the blackout period added to the urgency felt by the crew of the Hail Mary.
Reader's Guide
The surface is characterized by vast red deserts and polar ice caps, similar to the real-world planet but modified by human infrastructure. Habitats are clustered in shielded valleys or domes designed to withstand radiation and pressure differentials. Atmospheric conditions remain thin and cold, requiring pressurized suits for any EVA operations. During the crisis, temperatures dropped significantly as solar heating failed. Dust storms become more frequent due to atmospheric instability caused by failing climate control systems. Significance lies in its role as a lost colony. While Earth focused on launching the Hail Mary, Mars was left to fend for itself with dwindling resources. Over time, many facilities were abandoned or repurposed into emergency shelters rather than active research stations.
