Space today
Today's space in one place. Positions are computed from public orbital data, and space weather is fetched from the NOAA Space Weather Prediction Center (SWPC) every 10 minutes.

In everyday life
- Sunlight takes about 8 minutes 20 seconds to reach Earth — the Sun you see is how it looked 8 minutes ago, and the Solar 3D view draws today's positions on that scale.
- On high-Kp days geomagnetic storms can enlarge GPS errors — a reason to check space weather before flying a drone or running GPS-guided farm machinery.
- If a bright dot crosses the evening sky for a few minutes without blinking, it may be the ISS — compare it with the pass times on the Tonight page.
