One hundred years of launches

The chart counts registered objects launched into outer space, not only active satellites. The first 31 years are deliberately empty: the space age began in 1957.

What if the 2025 launch rate continued?

Choose a simple rate scenario. This is arithmetic for scale—not a forecast of launches, failures or re-entry.

04 · What these numbers mean

What these numbers mean

A launched object may later re-enter, stop working or fragment. That is why total launched, still in orbit, functioning satellites and tracked objects are different figures.
