Description of Driving Event:
The MIDAS experiment was designed for one atmosphere pressure, and thus venting was not seen as a requirement and was not designed in. However, the specified minimum and maximum pressures on Shuttle and Mir would have produced a potential maximum pressure difference of 4 psi in the worst case. Venting was back-designed into the system after the fact, when this was determined.
