Can a new space race connect the world to the internet?

NEW YORK (AP) — It's a 21st century space race: Amazon, SpaceX and others are competing to get into orbit and provide internet to the earth's most remote places.

And like the last century's battle for space supremacy that was triggered by the Soviet Union's launch of Sputnik 1, this one involves satellites. Thousands of them.

More than a dozen companies have asked U.S. regulators for permission to operate constellations of satellites that provide internet service. Not all are aimed at connecting consumers, but some have grand and global ambitions.

"The goal here is broadband everywhere," Amazon founder Jeff Bezos said at a conference in June.

With half the world's population — more than 3 billion people — not using the internet , it's a huge potential market. And there's the obvious benefit on the ground: Not having internet access makes it difficult or impossible to apply for many jobs, for kids to do homework, for people in remote areas to get medical care, and to participate in the global economy.

But this new wave of spaced-based internet faces hurdles. It is expensive to launch, technologically complex and could prove too costly for the very people it hopes to reach.

And then there's space junk. More on that in a moment.

Satellite internet already exists, dominated by a handful of companies like HughesNet and Viasat that have huge, expensive satellites sitting 22,000 miles (35,000 kilometers) from the earth and covering big territories on the ground. But the service is expensive and limited, comes with data caps and lags, and doesn't have many users.

The new satellites are smaller, cheaper, and closer to the earth, so theoretically signals travel faster and applications like online gaming that need instant responses would work better. And they have some...
