The Kármán line, which marks the boundary between Earth's atmosphere and outer space, is typically considered to be around 62 miles (100 kilometers) above sea level.
It takes a space shuttle about 8 to 9 minutes to reach outer space once it launches from Earth. This is typically when the shuttle reaches an altitude of about 100 kilometers (62 miles) above the Earth's surface.
Outer space is typically considered to begin around 62 miles (100 kilometers) above Earth's surface, where the Kármán line is located. Beyond this point, the Earth's atmosphere becomes very thin and spacecraft are considered to be in outer space.
It takes approximately 10 minutes to reach outer space from the Earth's surface in a spacecraft traveling at escape velocity, which is about 25,000 miles per hour. This means it would take less than an hour to travel to outer space at this speed.
Most people who went into outer space have survived.
Outer space officially begins at the Kármán line, which is located approximately 100 kilometers (62 miles) above sea level. This is equivalent to 100,000 centimeters above the Earth's surface.
