In aviation and aviation meteorology, a flight level (FL) is an aircraft's altitude at standard air pressure, expressed in hundreds of feet.
Suborbital Flight: Suborbital spaceflight occurs when a spacecraft reaches space but its velocity is such that it cannot achieve orbit. Many people believe that in order to achieve spaceflight, a spacecraft must reach an altitude higher than 100 kilometers (62 miles) above sea level.
8 paź 2019 · On Earth we have air pressure, created by air molecules drawn down by gravity. In space there’s also a pressure created by particles like ions and electrons. These particles, heated and accelerated by the Sun create a giant balloon known as the heliosphere extending millions of miles out past Pluto.
Dr. Ryan Stone, a brilliant medical engineer on her first Shuttle mission, with veteran astronaut Matt Kowalsky in command of his last flight before retiring. But on a seemingly routine spacewalk, disaster strikes.
The flight levels correspond to the altitude in 100-ft increments (hectofeet) above the pressure surface of 1,013.25 hPa calculated according to the standard atmosphere. For example, FL050 is the pressure surface 5,000 ft above the pressure surface 1,013.25 hPa.
What's slower than a speeding bullet, and able to hit tall buildings at a single bound? Original title: Flying High. Still craving for the love of his life, ex-Air Force pilot Ted Striker follows Elaine onto the flight that she is working on as cabin crew.
As for the air pressure on the International Space Station being one bar, technically the atmospheric pressure could be lower, but it couldn't be as low as it is near Mount Everest's summit because humans could only survive those pressures a few minutes at most.
