The Immortal Jellyfish: The Animal That Can Never Die (Nearly)

The Immortal Jellyfish: The Animal That Can Never Die (Nearly) By Mr Yuan Turritopsis dohrnii, famously dubbed the "immortal jellyfish," is a remarkable species found in temperate to tropical waters around the world. This tiny jellyfish has a unique claim to fame: it’s one of the rare creatures capable of reversing its life cycle. After reaching sexual maturity as a solitary medusa, it can revert completely to a sexually immature, colony-forming polyp stage, defying the typical progression of aging (Wikipedia, 2025). Like other hydrozoans, T. dohrnii begins life as a free-swimming larva called a planula. Once the planula settles on the sea floor, it transforms into a colony of polyps that are genetically identical clones. These polyps form a highly branched structure, unlike most jellyfish, and eventually bud off into medusae—the free-swimming adult jellyfish we recognize. Upon reaching sexual maturity, these medusae actively prey on other jellyfish species, showcasing their ...

A Day in the Life on a Future Mars Colony

 

“A Day in the Life on a Future Mars Colony”

By Mr Choco Frog

Living on Mars—what a headline, right? But what’s daily life like for those brave enough to make the Red Planet their home once the fanfare dies down? Let’s explore a hypothetical day on a future Mars colony, backed by science and a sprinkle of imagination.




Morning: The Sun Rises Over Red Dust

Colonists wake up to their AI assistants cheerfully nagging them to hydrate and start their day. With mornings on Mars stretching slightly longer than Earth’s—thanks to a 24.6-hour "sol"—there’s no excuse to skip breakfast. Meals are nutrient-packed and grown in hydroponic greenhouses within the habitat. Think algae smoothies, kale salads, and maybe a treat from 3D-printed food systems if supplies allow (NASA, 2021).

Mars habitats are designed for efficiency and safety. Walls insulated with regolith (Martian soil) protect against radiation, while solar panels power everything from oxygen generators to coffee machines. But coffee is strictly rationed—someone’s always keeping a suspiciously close eye on the last few beans.

Mid-Morning: Science and Survival

The colony’s survival depends on teamwork. Scientists, engineers, and builders each have vital roles.

  • Scientists focus on analyzing soil and ice samples, searching for water sources or traces of ancient life. Recent Mars rover missions have proven that water exists as ice just below the surface, making such explorations both exciting and necessary (ESA, 2023).

  • Engineers maintain life-support systems. Oxygen is generated through electrolysis, splitting water molecules into breathable air. Every failure is a potential disaster, so their work is critical.

  • Builders expand living spaces and storage facilities, often constructing underground tunnels to shield colonists from solar radiation.

Outside, colonists wore spacesuits with advanced life-support systems for tasks like inspecting solar panels or gathering resources. Dust storms—a frequent Martian hazard—mean every outing feels like an extreme sport.

Lunch: A Taste of Mars

Lunchtime is a mix of creativity and compromise. Algae-based proteins and vegetables dominate the menu. While food variety is limited, the ingenuity of colony chefs keeps meals from becoming monotonous. A recent study by Purdue University highlights how algae can be a sustainable protein source for long-term space missions, making it a staple in Martian diets (Perkins, 2022).

During lunch, colonists bond in the common area, sharing stories about their morning. The humour is dry, much like Mars, but camaraderie helps stave off isolation when the nearest neighbour is millions of kilometres away.

Afternoon: Exploring the Red Planet

Afternoons are for exploration and innovation. Teams venture out in pressurized rovers, scouting for resources or studying geological formations like Olympus Mons—the tallest volcano in the solar system. Mapping the terrain helps ensure safe future expansion.

Back at the habitat, colonists tackle research projects. For example, one group might work on terraforming experiments, exploring ways to release carbon dioxide trapped in Martian soil to thicken the atmosphere. Others test 3D printing with regolith to produce tools and spare parts, reducing dependence on Earth resupply missions (NASA, 2022).

Evening: Relaxation Under the Stars

As the Martian sunsets, colonists gather for dinner. Evening meals are social events, offering a chance to unwind and share laughs. Virtual reality (VR) is a popular evening activity, allowing settlers to "escape" to simulated Earth environments or enjoy multiplayer games.

For those who prefer solitude, stargazing is unbeatable. Without Earth’s atmospheric interference, the night sky over Mars offers an unparalleled view of the cosmos, with Jupiter and Saturn appearing brighter than ever (Smithsonian Magazine, 2023).

Night: Rest and Recharge

Colonists retire to their sleep pods, custom-built for comfort and safety. Artificial intelligence systems monitor the habitat overnight, ensuring air quality and power levels remain stable. Falling asleep on Mars is a mix of exhaustion and awe—you're part of a new chapter in human history.

Looking Ahead

Life on Mars is tough, but it’s also exhilarating. Each sol brings humanity closer to becoming an interplanetary species. With innovations in technology and the indomitable human spirit, the dream of Martian colonization feels more real every day.

Would you sign up for a one-way ticket to Mars? The Red Planet might just be waiting for you.
