What are Orbital Radar's Worlds?
A World is a live, interactive 3D globe of a body in the Solar System. Every World renders real data: the Earth globe tracks every active satellite, the ISS and tracked debris in real time, while the Moon globe tracks live lunar orbiters and maps Apollo and robotic landing sites, craters and Artemis candidate regions. The globes share one engine and one design language, and both the Earth and Moon globes carry a built-in switcher to hop between them.
The Moon globe is the newest World: it tracks five lunar orbiters — four on live NASA JPL Horizons ephemeris — and renders the real day/night terminator, the Moon's current phase and the live Earth–Moon distance. The Mars globe tracks Mars orbiters and both moons (Phobos & Deimos) on live JPL Horizons ephemeris, with the Perseverance and Curiosity rovers and named features mapped on the surface; spacecraft beyond Earth orbit are tracked on Deep Space.

Frequently asked questions
What are Orbital Radar's Worlds?
Worlds are Orbital Radar's live, interactive 3D globes. Each one tracks real spacecraft and maps real surface features for a body in the Solar System. Earth, the Moon and Mars are live now.
Can I track spacecraft orbiting the Moon?
Yes. The Moon globe tracks five lunar orbiters — the Lunar Reconnaissance Orbiter (LRO), Chandrayaan-2, Danuri (KPLO), CAPSTONE and the Queqiao-2 relay — four of them on live NASA JPL Horizons ephemeris, updated continuously.
Is there a Mars globe?
Yes — the Mars globe tracks Mars orbiters (MRO, Mars Express, Mars Odyssey, ExoMars TGO and the UAE's Hope) plus both moons, Phobos and Deimos, on live JPL Horizons ephemeris, with the Perseverance and Curiosity rovers, landing sites and named features mapped on the surface.
How are the globes kept accurate?
The Earth globe uses SGP4 propagation from the latest published two-line elements (TLEs) sourced from Space-Track and CelesTrak. The Moon globe uses NASA JPL Horizons ephemeris for its live orbiters. Positions update continuously.
Is Orbital Radar's Worlds free to use?
Yes. Every Orbital Radar globe — Earth, the Moon, Mars and Deep Space — is free to explore in your web browser, with no account or download required.
How often do the globes update?
The Earth globe recomputes every tracked object's position every second using SGP4 propagation. The Moon and Mars globes refresh their orbiters and both Martian moons from NASA JPL Horizons ephemeris continuously, and surface maps, landing sites and mission data update as new data is published.
What data sources power the Worlds?
Earth uses two-line elements (TLEs) from Space-Track and CelesTrak. The Moon and Mars globes use NASA JPL Horizons ephemeris for orbiters and moons. Surface imagery comes from public-domain USGS and NASA mosaics, and live Mars weather comes from the Curiosity rover's REMS station (NASA / Centro de Astrobiología).
What is the Deep Space view?
Deep Space tracks spacecraft operating far beyond Earth orbit — interplanetary probes and deep-space observatories — on a live map of the Solar System, complementing the Earth, Moon and Mars globes.
