but still an astronaut in a spacesuit is not a spacecraft, is a human called a vhicle?? No, hes called a human!!:facepalm:
How can you cal it a spacecraft, does it haveany mode of transport, the way the astronaut moves is with his limb(holding on to the station bars) or attached to the robotic arm. The suit doesnt move him, the suit protects him, thats why the suit was made, it wasnt made as a transport.I i havn't notuced that the answer is"Yes- an astronaut on EVA is a spacecraft."I prefer to say that the susite is the spacecraft, not the astronaut ON the EVA!
Urwumpe, how the hell did i forget that!?!?!?:facepalm:How can you cal it a spacecraft, does it haveany mode of transport, the way the astronaut moves is with his limb(holding on to the station bars) or attached to the robotic arm.

Yes, but in an EVA suit, there is no 'propulsion' system, its his limbs that are moving it physically. In a spacecraft, he does an action, which a computer inteprets and moves the spacecraft which makes it a vehicle.Yes of course it protects him, like each spacecraft does it.
And like in any spacecraft, an action of the pilot is required to move. (The pilot can also be a CPU)
Lets go over the requirements for a manned spacecraft.
Does it hold people/persons? (check)
Does it hold oxygen? (check)
Does it have propulsion? (check)
Can it carry payloads? (check)
Will it blend? (not check)
I'd think you could count a EVA suit as a manned spacecraft
EVA is EXTRA-vehicular activity... 'extra' is latin for outside, thus it's not activity IN the spacecraft. If the suit is a spacecraft itself then it's not an EVA by definition. Then it would be an IVA (INTRA-vehicular activity )
That's a clever argument, however I don't think the assigned EVA definition prohibits the EVAer itself from being a vehicle. The term EVA is used in relevance/reference to the Shuttle or Station, so is 'extra' in that regard only.EVA is EXTRA-vehicular activity...

Like an extra-terrestrial being doesn't need to live in space? He can live on a [ame="http://en.wikipedia.org/wiki/Terrestrial_planet"]terrestrial planet[/ame] and still be an extra-terrestrial. He is just "extra-" to the point of reference, in this case the Earth. In the case of an EVA, the point of reference is the host vehicle - ISS, Shuttle, etc.That's a clever argument, however I don't think the assigned EVA definition prohibits the EVAer itself from being a vehicle.

planetary: of or relating to or characteristic of the planet Earth or its inhabitants
"define:terrestrial animal":@tblaxland; an extra-terrestrial defines someone not of this earth. If you google "define:terrestrial" then you will get this:
That said, you win the googlefightTerrestrial animals are animals that live predominantly or entirely on land
You could say they are engaging in extra-terrestrial activity (but then so would I be if I was swimming ), but not that their origins are extra-terrestrial.Wouldn't all astronauts then be extra-terrestrials? (They're not on the planet while on ISS, they're 'out from' earth so to speak )
"define:terrestrial animal"
Definitions of terrestrial animal on the Web:
Terrestrial animals are animals that live predominantly or entirely on land, as compared with aquatic animals, which live predominantly or entirely in the water (e.g., fish, lobsters, octopuses), or amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g., frogs).
Animal which lives on land.
Definitions of Extra-Terrestrial on the Web:
Extraterrestrial life is defined as life which does not originate from planet Earth. The word "extraterrestrial" is derived from the Latin extra ("outside", "outwards") and terrestris ("earthly", "of or relating to the Earth").
A form of life assumed to exist outside the Earth or its atmosphere.
