About issonlive
issonlive.app is a quiet editorial site about the International Space Station. We show you where it is, who is aboard, and when it will cross your sky.
It is built by David Fernández, the developer behind the Android companion app. The web you are reading rebuilds itself every hour: orbital elements from Celestrak, position computed locally from those elements with SGP4, schedule from The Space Devs, crew from NASA.
Not affiliated with NASA, ESA, JAXA or Roscosmos.
FAQ
How do I see the Station with my own eyes?
Wait for a clear evening, find a spot away from streetlights, look toward the western horizon at the time we tell you, and watch a steady bright dot drift across the sky for three to five minutes. It does not blink.
Why does the time change every day?
The Station orbits Earth every 92 minutes, but Earth rotates underneath. So consecutive passes happen at different times of day.
