    The result was the shortest spacewalk in U.S. history.

    That raises the question as to what actually classifies a spacewalk. So they step outside for a minute or two, complete no extra-vehicular activity (EVA) whatsoever, but it's all good because they made space history?

    I guess technically, strictly speaking, it is a spacewalk but doesn't the definition of "spacewalk" include having to actually perform a task, in this case replacing a transistorised switch that had disabled one of four large gyroscopes?

    • Space walks seem to very rarely have anything to do with walking, so I don't see why it should have to have anything to do with productive work as that isn't even in the name :-)

      Walking is somewhat "tricky" in the absence of gravity or some sci-fi gizmo like magnetic boots.

    • This [wikipedia.org] is a spacewalk.

      • It says "There have not been any EVA's during flights to and from the Moon, or orbiting the Moon.", but I seem to remember reading about an EVA to inspect some part of the Command Module on a return flight from the Moon, and even a movie taken during that EVA. Anyone with better memory than mine?

    A stuck switch?
    The "vent-suit-atmosphere" switch perhaps?
    What kind of half-assed situation is this?
    They don't have enough telemetry to determine if a switch (or circuit) is on or off at a given point in time?

    Seriously though, if a "stuck switch" can give an (apparently false) indication of imminent loss of air, there's something seriously whacked in their suit design.

      Well, you could have telemetry on every circuit. In fact, that's the NASA way -- every switch and circuit breaker has a telemetry unit, and that unit probably feeds another unit that sends back telemetry about the telemetry.

      And before long, you have... the NASA EVA suit, which is 1) too big to fit t
