Space is just up there: Earth's air is an apple-skin-thin shield

A Space Daily explainer shows that the 100-kilometre Kármán line is a regulatory boundary, not a physical cliff; if you drove straight up at highway speed you’d reach space in under an hour, illustrating how incredibly thin Earth's breathable air is. About 99% of the atmosphere’s mass sits in the lowest ~32 km, and by 100 km altitude the air is roughly one millionth as dense as at sea level. The atmosphere’s layered protection—troposphere for life-supporting gases and the ozone-rich stratosphere—makes surface habitability possible, underscoring how the “apple-skin” thickness of the air is truly remarkable.

Captured V-2 Camera’s 1946 Flight Gave Earth Its First View from Space

In 1946, a captured German V-2 rocket carrying a 35mm DeVry camera reached about 105 kilometers over White Sands, producing the first photographs of Earth from space. The grainy frames showed Earth's curvature and horizon against black sky, predating any formal boundary for space—the Kármán line—by decades. The camera survived the mission, while the rocket and many of its builders did not, and the achievement is often credited to Clyde Holliday and the Johns Hopkins APL team who adapted gear meant for other uses to peer into the upper atmosphere.

Blue Origin Completes Multiple Suborbital Flights with New Passengers

Blue Origin successfully launched its 70th person into space on its 13th passenger flight using the New Shepard vehicle, with the crew including the 750th person in history to reach space. The flight, carrying six tourists, reached above the Kármán Line, marking a significant milestone in commercial space travel.

Explained: The Distinction Between Outer Space and Deep Space.

Outer space refers to anything beyond Earth, while deep space starts beyond our moon and can refer to things beyond our solar system entirely. The Kármán line, an invisible line around 50 to 60 miles above Earth's surface, marks the boundary between Earth and outer space. Voyager 1, launched by NASA in the 1970s, is the furthest humans have reached into deep space, currently floating more than 14 billion miles from Earth. The terms matter for keeping track of things, as NASA has an entire communications setup to check in with all deep space missions, appropriately named the Deep Space Network.
