How would your life be without sateillites?

Not very different.

We lived - quite happily - for many many centuries without them.

What they have done, mainly, is to speed up previously available processes - such as weather forecasting, communications, and scientific monitoring of the planet.

You'd lose your GPS systems, but maps were fine for many people.

You'd lose instant TV pics from the other side of the world, but would that matter too much?

You'd lose the Hubble space telescope - and that's serious, but not a major impact on most people's lives.
