The sky, made legible.

Track what's overhead. Orbital propagation, pass prediction, and catalog visualization built on public two-line element data — a sovereign view of the objects sharing our skies.

Planetary defense. Track near-Earth asteroids and their close approaches with live NASA data — impact-hazard scales (Torino, Palermo), time acceleration, and local observability by city, all in an OODA situational frame.

How stars and their disks are born. An interactive, physics-first walkthrough — the Jeans criterion, free-fall collapse, infrared disk detection, and the nebular theory of the Solar System.

How other worlds are made. An interactive, bilingual walkthrough of exoplanet formation — the frost line, core accretion and migration, the transit method and the habitable zone — with simulators, games, challenges and real examples.

Play with the physics. Orbital mechanics, transfer manoeuvres, and n-body trajectories you can run, pause, and tweak directly in the browser — no install, no math anxiety.

The mechanics of getting there. Rocket propulsion and orbital dynamics from first principles — the rocket equation, staging, vis-viva, Kepler's laws — with live calculators and the real orbits of every planet, moon and satellite regime.

The rules above us. An interactive reference to the law of outer space — the five UN treaties and the Artemis Accords — for agencies, policymakers and operators who need the framework clear and concrete.

Securing the space mission. An interactive, bilingual reference to space cyber risk — the attack surface by segment, jamming and spoofing, the CIA+A model, and the controls and frameworks that protect a mission — with games, challenges and drill-down detail.

From Sputnik to New Space. An interactive, bilingual history of leaving Earth — the milestone timeline, rockets drawn to scale, the people who made it happen, and the New Space era explained in detail — with anecdotes, games and challenges.

Eyes on the planet and the Sun. Georeferenced satellite imagery over any country or city — NOAA's GOES, NASA's MODIS and VIIRS, Esri and Sentinel-2 — with a compare/blend layer, NOAA's animation loop, environmental layers for fires, sea-surface temperature, aerosols and precipitation, and real-time space weather from NOAA's SWPC.
