What is the vacuum pressure of space?
Measurement
| Vacuum quality | Torr | Pa |
|---|---|---|
| Ultra high vacuum | 1×10−9 to 1×10−12 | 1×10−7 to 1×10−10 |
| Extremely high vacuum | < 1×10−12 | < 1×10−10 |
| Outer space | 1×10−6 to < 1×10−17 | 1×10−4 to < 3×10−15 |
| Perfect vacuum | 0 | 0 |
Can atmosphere exist in a vacuum?
While gravity is most certainly a real thing, the answer to this question is not “because gravity is stronger”. The actual answer is that the vacuum of space does not exert any force on the atmosphere at all.
Why does space officially begin 62 miles above the Earth?
The AP reports that organizers claimed “the ship crossed the official 62-mile-high border of space.” Why does space officially begin 62 miles above the Earth? Because 62 miles is about 100 kilometers, and 100 is a nice round number.
Is the space between stars really empty?
In most cases, the space between stars and the vast regions between galaxies are not really empty. Those regions usually contain gas molecules and dust and effectively make up a vacuum. For purposes of law and record-keeping, most experts consider space to begin at an altitude of 100 km (62 miles), the von Kármán line.
What is the actual length of the International Space Station’s orbit?
NASA, US Air Force, and the FAA recognize the boundary as 50 miles. However, NASA Mission Control recognizes the line as 76 miles because it is the point at which atmospheric drag is felt.
Is it possible to go to space?
That answer depends entirely on what you call ‘space’; and yes, if you have a special aircraft that can manage to achieve such high speeds, you could actually reach space! However, let’s tackle the most basic question first… What is ‘space’? That might seem like a dumb question at first, right?
