A deep space journey from the Milky Way to our Solar System.
Gravitational shockwave expanding at speed c. Spacetime is unbending to flat Zero-G!
Thriving global population across 7 continents with advanced science, space exploration, and industry.
Mammals, birds, reptiles, and millions of deep-ocean marine creatures in rich ecosystems.
Dense rainforests, phytoplankton, and grasslands generating 21% pure breathable oxygen through photosynthesis.
Earth has one permanent natural satellite — the Moon (ചന്ദ്രൻ). Formed 4.5 billion years ago after a collision with a Mars-sized protoplanet (Theia), the Moon is crucial for maintaining Earth's stable climate, seasons, and ocean tides.
Continuously inhabited orbital research laboratory with multinational astronaut crews.
Revolutionary deep-space observatories imaging the earliest stars and cosmic origins.
Constellations providing high-precision positioning, navigation, and global time sync.
High-speed global satellite internet, weather monitoring, and global telemetry networks.
Creates Earth's 4 distinct seasons (Spring, Summer, Autumn, Winter) and stable climate.
Counter-clockwise spin causes the Sun to rise in the East and set in the West.
Rotational speed at Equator: ~1,670 km/h (1,037 mph).
Historical facts and mission entry lore.
No permanent human settlement. The Junior Astronaut Mission will be humanity's pioneer crew!
No evidence of multi-cellular organisms or animal life has ever been detected.
Lacks organic soil and natural water cycle. Plants can only survive inside sealed Hydroponic Greenhouses.
Build and balance a self-sustaining outpost for 4 junior astronauts. Balance oxygen, water, hydroponic food, and power grids.
NASA telemetry engineers are currently calibrating the planetary surface models, atmospheric pressure physics, and survival modules for this celestial body.
Unmanned probes and orbiter radar are mapping terrain. Junior Astronaut Outpost deployment for this sector will unlock in an upcoming update!
All celestial bodies are loaded from planets-data.js. Whenever you add a new entry to the array, the frontend automatically:
// Example: Adding Saturn's Moon Titan:
{
id: "titan",
name: "Titan (ടൈറ്റൻ)",
type: "playable",
orbitRadius: 360,
color: "#d4a373",
gravity: "0.14 g",
radiation: "Low (Dense Atmosphere)",
hazards: ["Methane Rain", "Extreme Cryo-Cold (-179°C)"],

}
Observing how each planet spins on its own axis (Spin on Axis). Compare standard Prograde spin, Venus's Retrograde reverse spin, and Uranus's 98° Sideways Roll.
Rotates counter-clockwise. Stabilized by the Moon. Sun rises in the East and sets in the West.
Spins backwards! If standing on Venus, the Sun rises in the West and sets in the East! Day is longer than year.
Extreme sideways tilt rolls like a wheel along its orbit! Poles have 42 years of daylight and 42 years of night.
Fastest rotation of any planet! Completes a day in under 10 hours, flattening its poles and whipping up supersonic storms.
Your goal is to build and balance life-support modules on the planetary grid so your 4 astronauts can survive indefinitely.
Solar Arrays generate electricity (+30 kW) only during DAY. At NIGHT, solar shuts off! You must build Battery Banks 🔋 to store energy, or your life support systems will power down!
Astronauts consume oxygen continuously. O₂ Generators use electricity to scrub CO₂ and produce fresh breathable air.
Drills into subsurface permafrost to supply drinking water and irrigate the greenhouse, plus produces raw construction alloys.
Uses power and water to cultivate crops, replenishing the astronauts' food supplies.
Blocks lethal cosmic rays and solar flares, preventing crew radiation sickness.
Tracks Coronal Mass Ejections (CME), Solar Energetic Particle (SEP) storms, and M/X-Class Solar Flares.
Contains real astronaut biodosimetry data, DNA damage repair markers, and immune system adaptation from ISS and deep-space analog missions.
Topography and thermal maps of Shackleton Crater and the Lunar South Pole, mapping permanently shadowed regions (PSRs) with water-ice volatiles.
Atmospheric density measurements (610 Pa, <1% of Earth), ambient thermal swings (-125°C to 20°C), and global airborne dust opacity (tau values).
Generating power during day is easy. The hard part is storing enough kW in Battery Banks to prevent life support from shutting down during freezing night.
If you build only Solar Arrays and forget Battery Vaults, nighttime battery drain collapses your oxygen scrubbers within minutes!
Turning on the Magnetic Forcefield Pylon envelops the base in a protective cosmic bubble, dropping radiation exposure to 0.
Shields consume a massive 70 kW of continuous electricity. Running shields during a dust storm or at night rapidly empties battery reserves.
Hydroponic Bio-Domes grow fresh vegetables, preventing astronaut crew starvation.
Crops consume water every second. Without active Ice Drill Extractors supplying meltwater, the greenhouse quickly withers.
Driving the 6-wheel rover across crater ridges lets players scout landing sites and harvest extra alloy materials.
The farther you drive from the lander airlock, the higher the risk if a sudden DONKI solar flare or dust storm strikes while outside.
One day on Mars! Because Mars spins slightly slower than Earth, a Martian sol lasts 24 hours, 39 minutes, and 35 seconds.
Invisible energy bullets shot out by the Sun and distant exploding stars. On Earth, our air and magnetic field block them. In space, astronauts need thick rock domes or magnetic shields!
On the Moon, gravity is only 1/6th of Earth; on Mars, it's 3/8th. Astronauts can jump super high, but heavy equipment doesn't press down firmly on the ground!
Space dust and crushed rock! It's super sharp because there is no wind or water on the Moon to smooth it out. We can bake it into solid bricks to build safe domes!
When humans breathe, we inhale Oxygen and exhale Carbon Dioxide. A scrubber recycles the air so we never run out of breath in our space helmets.
When you have to give up one good thing to get another! (Like choosing whether to use electricity for heating or for growing plants).
The Space Weather Database (DONKI) confirms an incoming Coronal Mass Ejection. Ionizing radiation will impact your sector in 3 minutes. How will you allocate outpost resources?
The trade-off has taken effect on your outpost vitals.
The colony's vital resources have dropped to critical levels. The astronauts are requesting immediate emergency intervention.
As Flight Director, you can order an Emergency Orbital Resupply Drop to deliver emergency batteries, bottled O₂, water, and food to stabilize the base!
Join an active team or compete with other crews to build planetary colonies and earn Science Points!
Real-time status of bases established by all teams across Moon, Mars, and the Solar System.
Step 1: Build a Solar Array ☀️ to generate clean electricity during daytime.
High cosmic radiation detected. Shield generators operating at maximum.
