Welcome to the space elevator, the only elevator that goes to space.
As you climb, the temperature will continue to drop.
Cirrus clouds are wispy clouds made out of ice crystals.
Cirrocumulus are patchy clouds that can blanket the sky.
Cumulonimbus are tall, towering clouds that can produce lightning, tornadoes, and hail.

Above this altitude is known as the "death zone", because there isn't enough oxygen for human life.

Welcome to the stratosphere.
Unlike the troposphere, the temperature in the stratosphere increases the higher you go.
The stratosphere is home to the ozone layer, which protects us from harmful UV rays.
You are currently in the troposphere, the lowest layer of the atmosphere.
The troposphere contains 99% of the water vapor in the atmosphere.
This elevator ride needs some music...
Jet streams are bands of strong winds in the atmosphere. They can reach speeds of up to 450 km/h.
Don't worry, the elevator is pretty strong... I think.
The air in the mesosphere is very thin. It has less than 1% of the pressure as the air at sea level.
Congratulations! You have reached the mesosphere and are now halfway to space.
This is the coldest part of Earth's atmosphere.
Since weather balloons can't reach this height, rockets with sensors are used to learn more about the mesosphere.
Welcome to the thermosphere, the final layer on our journey to space.
At 100 km high, the Kármán line is usually accepted as the start of outer space.
You are about to reach a place fewer than 1,000 humans have ever been.
Temperatures in the thermosphere can reach 2,500°C, but molecules are so far apart that you wouldn't even feel it.
Highest Aircraft Ejection
This is the Armstrong limit - above this altitude your saliva and tears will boil if you don't have a pressure suit.
Nacreous clouds are rare clouds found in polar regions. They are made of small ice particles that scatter light in colorful ways.
1933 balloon altitude record
Hot Air Balloon
High-altitude platform station
As air pressure drops, so does the temperature needed to boil water. At this altitude, water boils at just 54°C.
As the air gets thinner, there are fewer molecules to scatter light. So the sky starts getting darker.
The SR-71 is one of the fastest planes ever made. It can fly at over 3 times the speed of sound.
Now would be a good time to pick out your space suit.
It's a bit chilly, pick a scarf to stay warm.
Highest altitude glider
Sud-Ouest Trident II
1958 rocket plane altitude record
Space Shuttle Re-entry
The mushroom cloud from the largest ever nuclear test, the Tsar Bomba, reached this altitude.
Experimental hypersonic aircraft
The ash cloud from the eruption that destroyed Pompeii reached this height.
If you've ever wondered where your lost balloons went, at this height a typical party balloon will pop.
Highest paper airplane flight
Launched from a balloon, this is the highest a paper airplane has flown.
Felix Baumgartner was the first person to break the sound barrier in freefall. He reached a top speed of 1,356 km/h.
Congratulations! You have made it 0.01% to the moon.
Reaches max aerodynamic pressure
The mushroom cloud from the Castle Bravo nuclear test reached this altitude.
Space elevators are actually a possible idea being considered by scientists.
They could potentially offer a cheaper and safer way of getting to space.
The hard part is making a strong enough cable. And finding enough elevator music...
Sutter's Mill Meteor
Sprites are a rare form of lightning spotted over thunderstorms that only last a fraction of a second.
While normal lightning is around 4 km long, sprites can reach lengths of up to 50 km.
Since the speed of sound depends on the temperature, sound travels 15% slower up here.
The world's fastest elevator travels at 74 km/h. A space elevator with the same speed would take 80 minutes to reach space.
Blue jets are a rare form of lightning that arc upward in a brilliant blue flash.
Noctilucent clouds are the highest altitude clouds in the atmosphere. They are only visible at night and at higher latitudes.
Most meteors burn up in the mesosphere. It's estimated that over 48 tons of meteors hit the atmosphere every day.
1976 altitude record
1938 altitude record
1960 skydive altitude record
With nothing but a duct-taped pressure suit, Joseph Kittinger jumped from an open gondola and set a record that would last more than 50 years.
1935 balloon altitude record
First aircraft to reach Mach 2
First stage separation
High altitude balloon record
As particles from the sun hit the atmosphere, they excite the atoms in the air.
These excited atoms start to glow, creating brilliant displays of light called auroras.

Current record for highest skydive
