How to spot the space station
- Check the time and direction in the table, and be outside a few minutes early.
- Look low in the direction it appears; it rises from the horizon in a few seconds.
- It moves steadily and does not blink. A blinking light is a plane.
- Higher passes are brighter: anything above about 40° is easy to see, even from a city.
- No telescope needed. Binoculars help a little, but a phone camera on a long exposure shows the trail best.
ISS, Tiangong and Hubble compared
| International Space Station | Tiangong | Hubble | |
|---|---|---|---|
| Run by | US, Russia, Europe, Japan, Canada | China | NASA and ESA |
| Crewed | Yes, since November 2000 | Yes, since 2021 | No |
| Orbit inclination | 51.6° | About 41.5° | 28.5° |
| Seen from | Most inhabited places | Up to about 50° north and south | Only the tropics and subtropics |
The inclination sets how far north and south a craft travels. The ISS goes up to 51.6°, which is why it passes over London, Kyiv and Calgary but is seen only low in the sky from Scandinavia or Scotland’s far north. Hubble never rises high for anyone much beyond 35° north or south.
