COSMO-SKYMED 1

COSMO-SKYMED 1 is a satellite from Italy, launched on June 8, 2007 from Vandenberg, California, United States. It is in a low orbit, 574 km above the ground, and goes around the Earth every 96.2 minutes: 15.0 times a day, at 7.57 km/s (27,300 km/h). The orbit is sun-synchronous: it crosses every place at about the same local time of day.

Where COSMO-SKYMED 1 is right now

The gold ring is its orbit, and the line drops to the point on the ground under it. Inside the white circle it is above the horizon. Drag the globe to turn it, pinch or use the buttons to come closer; the target button brings you back to the satellite. The 2D map shows its path over the ground for the next lap: gold where it is in sunlight, dashed where it is in Earth’s shadow.

Can you see it?

Without a telescope

Yes

On a good pass it is about as bright as the stars of the Big Dipper: magnitude +2.8 at its best. It can be seen even from a town.

From where

Its orbit crosses close to both poles, so sooner or later it passes over every place on Earth.

A satellite shows only when your sky is dark and it is still in sunlight: in the hours after dusk and before dawn.

When it passes over you

The app works out its passes over your exact location, alerts you before one, and leads you to it with an arrow in the camera view.
