标题：The Scariest Spacewalk in 50 Years

Spaceflight is entering its cowboy era.

正文：Early this morning, four private astronauts blasted into orbit to carry out SpaceX’s most dangerous mission yet. After a few days of circling Earth, the passengers will suit up and open the hatch of their spaceship. All of the precious, breathable air inside their capsule will escape into the cold void. Two of them will venture out, gripping an exterior ladder with their gloved hands as they dangle over the planet. All four will be exposed to the vacuum of space, and they will rely on their spacesuits, which SpaceX has never tested in space before, to keep them alive. It will be the first civilian spacewalk in history—and perhaps the riskiest spacewalk in decades.
