Outer space may have just gotten a bit closer

The line where Earth’s atmosphere wanes—and outer space begins—has long been up for debate.
Reaching the stars just got a bit easier. A new study argues that the boundary between Earth’s atmosphere and outer space—known as the Kármán line—is 20 kilometers, or about 20% closer, than scientists thought. Though the new definition won’t make a difference for launching rockets and spacecraft, it could help clarify a legal debate that will set the rules for space policy—and commercial spaceflight—for years to come.
