Without satellites, modern technologies such mobiles phones and GPS would not exist.

We've all seen videos of satellites being blasted off into space - but once they're locked in orbit around the earth, how do we bring them back down?
Future robots will work side by side with humans, just as they do today.

Rather than fret about how many jobs future technologies will destroy, we should focus on how to shape them so that they complement the workforce of tomorrow.
Nature gave us ten fingers, so it makes sense to count to ten. But what happens when we run out of fingers?
Why are there 60 minutes in an hour, and not 10? Why do we count up to 10, anyway? Quentin, age five, wants to know.
Molecular machines are ready to join forces and take on real-world work.
Research on molecular machines won last year's Nobel Prize in chemistry. Now scientists have figured out a way to get these tiny molecules to join forces and collaborate on real work on a macro scale.
CSIRO research finds Australia needs to work better with global supply chains and make more specific products to survive.
A CSIRO report suggests Australian manufacturers need to better design custom products and hook into global supply chains to survive.
The computers of tomorrow are being taught to learn, reason and recognise emotions.
Computers are taking over our jobs, but this doesn't have to be a bad thing.
Intelligent machines are good at some jobs that were once done by humans.
Intelligent machines are taking on many of the jobs once carried out by humans but that doesn't mean we'll have mass unemployment.
Another job snatched by a robot?
Some suggest half of current jobs will be lost to automation over the next decade or two. But it's far too early to pit man versus machine.
Who gets to fire the gun? Man or AI-powered machine?
When it comes to weapons with artificial intelligence, there's an argument for keeping a human in charge of some of the action.
Can a machine really think, be in awe and wonder?
As machines get ever more complex as we strive to make them complete more complex tasks, it's time to ask again: will they ever be able to think? But what is thinking anyway?
Technology can be so frustrating at times, so what if it could understand your emotions?
How often do you get angry or frustrated with a machine or some piece of technology? Well what if a machine could sense our emotion and then change its behaviour to suit?
