Why don't airplanes ever go to the moon or other parts of space?
-------------------------------------------------------
answers:
nineteenthly say: Because they need air to fly.
-
Craig say: Because space is a vacuum and the airplane turbines require the constant thrust of air to keep the plane in motion.
-
I Wink I Think I Stink say: Nowhere safe to land. The moon and other planets are notorious for lax upkeep on their runways.
-
Ronald 7 say: Airplanes need air flowing under their wings for the lift
There is a reason Rockets don't have wings
They would be sheared off with the force of up to 1 Million Newtons and speeds of 17, 500 mph
-
quantumclaustrophobe say: They can only fly as high as the air supports them; the higher they go, the thinner the air, until finally they can't get any further up.
-
MARK say: An aeroplane is so-called because its design forces an uplift of air underneath its wings so that it flies rather than drops to the earth. As there is no air in space perhaps you could suggest how it will fly.
-
Jeffrey K say: There is no air in space. Air creates lift under its wings. This holds it up. A plane can not go higher than there is air to hold up its wings.
-
Clive say: Because they CAN'T. The engines only work in air, and there is no air in space. They rely on air passing through them to be able to burn the fuel and create thrust. Propeller engines don't work either as they only work because a spinning propeller is another way of creating thrust in air.
If there is no air, you need a completely different kind of engine. One that carries its own oxygen so that the fuel can burn, and doesn't rely on air flowing through it to create thrust. This kind of engine is called a "rocket".
So rockets carry liquid oxygen (which is why ice forms on the outside) and work on the principle of Newton's 3rd law of motion. Every action creates an equal and opposite reaction. Burn the fuel and throw it out the exhaust, and that action creates an opposite reaction that forces the rocket to go the other way. Bingo, you have an engine that doesn't need air to work and can function in space.
Just out of interest, the Russian R7 rocket was originally developed to be a very big missile. The trouble with it was that as it uses liquid oxygen, which has to be kept VERY cold or it turns back into oxygen gas, you can't fuel it until shortly before launch. Or else you'd have to keep the whole rocket in a freezer. This is no good if you want a missile you can instantly use to fire back when you get attacked. Hmmmm, not much practical use as a weapon. BUT it also works just as well for launching things into space. Just put a satellite or space capsule on the top instead of a bomb, and you have a usable space rocket.
What the Russians are using now, under the name Soyuz (which means Union), is the updated and improved version of the same thing. After hundreds of launches, you can trust it!

The Grim Reaper say: Your answer is in your own question.
" airplanes"
They fly in the air, not in airless space.
Also, the stewardesses do not like the zero gravity as their dresses keep lifting up.

rick29148 say: AIRplanes ?? as they need AIR to fly ?? no air in space ................................
-
Steven say: First airplanes need air to burn their fuel,
and they need air for lift, to get off the ground
but it's a good thing there is no air in space so that space craft can coast most of the way because the distance to the moon is about 30 times around the earth, and very few airplanes can fly even once around the earth
and no airplane goes fast enough to escape earth's gravity. You need to go about 35 times faster than a jet plane to get into space.

QuandariousGooch say: Cause you suffocate dummy
-
Adullah M say: Air planes need outside air for their combustion jet engines.
-
Poseidon say: Another stupid and immature troll question.
-
Bill-M say: The key word is Air like in Airplanes. They need AIR to Fly.
No air in space.
-
Chris Ancor say: It would take to long to get there.
-
Ghost Of Christmas Past say: The word airplane should give the game away. If there's no air, they can't plane.
-
poldi2 say: Airplanes need air to function, there is no air between the Earth and the moon or other parts of space.
-
Tom S say: Airplanes fly in air. Plus there is are no airports / landing strips on the Moon.
-
Dan say: Ask NASA, they could use a laugh.
-
britney_thao say: Airplanes are not able to fly out of the earth’s atmosphere. Outside of the atmosphere, there would be no air to lift their wings.
-
Who say: cos there aint any runways on the moon
-
yash rana say: As you know, Aircraft fly by the lift of air. airplane can fly in space too. but you need to modify its engine. earth has lots of air on our plane fly. so space can also has some kind of material on which we can fly.
Spacecraft mostly design on thrusters and gravitational pool of planets
-
Acetek say: Operative word here is AIR.
-
John say: Due to the shape of an airplane's wing, the flow of air over the wing creates "Lift". Space is a vacuum and since their is no air in space their would be no lift.
-
say: To escape the earth ozone without exploding you need to reach escape velocity which if I remember rightly is twice that of the speed of gravity. Also airplanes wouldn't be able to manoeuvre in space seeing as there is no air to displace therefore the direction of which you enter zero gravity is the direction of which you stay in space. To manoeuvre to places such as Jupiter, satellites sent to space must be sent in the direction of a planet such as mars' gravitational pull, in the right place so that it turns the direction enough to be on course to the next gravitational pull, and then so on until it is on course to Jupiter.3

pearlmar say: Because they don't have the capability to do so.
