Why is space walking called Extra-vehicular activity (EVA)?

Answer 1

because when you are a rocket scientist you have to make everything more difficult.

Answer 2

An "EVA" is in certainty "extra beneficial Vehicular interest"...no count if outdoors of the ISS or the different area vehicle (like the holiday) whilst orbiting the Earth or perhaps in transit to and from the Moon or on an analogous time as on the Moon (for that count). Any interest on the exterior of any area vehicle is considered an EVA. basic experience solutions something of the question (i might desire and picture) that there are no longer any gas-stations or munchie-marts everywhere out in area. If there is, something have been given previous me interior the information that I in no way imagined available my chum.

Answer 3

Because it's outside the vehicle [walking in space outside the spacecraft]?

I thought this would be self evident, since the vehicle is the spacecraft, naturally, walking outside it is "Extra Vehicular Activity"!!

All the best.

Answer 4

It might seem a bit over the top, but all these terms are needed to make sense of what somebody is "exactly" doing.

Extra - can mean external, outside, not part of, or beyond. So when somebody says Extra-terrestrial. That means something "outside" or beyond our Earth (earth in latin is known as Terra Firma).

Sometimes it can be hard to follow along NASA or the Military, but without those terms defined, it's actually harder to describe what's going on.

And after awhile, certain terms, like SCUBA almost make more sense then the acronym they stand for. (Self Contained Underwater Breathing Aparatus).

Good question! Thanks for asking!

Answer 5

I don't know why that particular name is used, but I do know that no walking is involved in an EVA in orbit. Where there is no ground and no gravity, you can't walk, you just drift or move or do activity outside the vehicle.

Answer 6

How would you get into space without a vehicle? And if you're inside the vehicle, you're not space-walking...'activity' refers to the fact that you can't 'walk' in space, just kind of float around holding onto things.

Answer 7

the EXTRA word is related to EXIT, that is, go outside.

Answer 8

because they come up with an acronym for everything
