Lego pieces that contain closed air spaces, like pneumatic tanks, would
not be very happy in a vacuum. But most Lego pieces do not contain air
and would likely be fine. Since Lego pieces are usually not airtight
when assembled, the outgassing from the inner walls of the ABS would
leak out before it could build up enough pressure to blow the brick
apart. I can imagine that an assembled minifig pop apart from internal
air pressure (and on the old-style solid stud minifig heads would likely
shoot off like a champagne cork), and one would assume that a
preassembled model would also fly apart. But more worrisome would be the
UV radiation, which would yellow those blue, white and light grey pieces
in record time. Further, it wouldn't do to stay in the space shuttle's
shadow while playing with Legos in deep space, since the temperature
drop would cause the ABS to become brittle and break when putting pieces
together. I'd keep a brick separator around, since getting the bricks
apart would be tricky through the spacesuit's gloves.

would lego peices survive vacum pressures?
