Space is Closer Than You Think

If you could drive straight up at highway speeds (about 100 km/h or 60 mph), you’d reach space in about an hour. The most widely used boundary of space, known as the Kármán Line, is 100 km (62 miles) above Earth’s surface. That’s closer than most people’s daily commute. It’s a reminder that space isn’t some impossibly distant place—it starts just beyond the sky we see every day.
