Some of these are pure computation — the planetarium and orrery calculate real orbital positions from the current date, no network needed. Others are genuinely live — the ISS tracker, satellite catalogs and launch countdowns are fetched from NASA, CelesTrak and The Space Devs. All key-less.
Frequently asked questions
- Do these need an internet connection?
- The computed ones (Planetarium, Orrery, Moon Phase) work fully offline. The live-fetched ones (ISS Tracker, Rocket Launch Countdown) need a connection.
- Are any of these real photos?
- Yes — Blue Marble and Live Sun use real NASA satellite imagery, not illustrations.
- Is a key needed for any of these?
- No — every space saver here uses key-less public APIs or pure astronomical computation.
- Are they accurate?
- The computed ones use real orbital mechanics for today's date; the live ones reflect real current spacecraft and mission data.
