The background pressure for the SEPAC experiments (Space Experiments with Particle Accelerators) was monitored by the vacuum gauge on the Spacelab pallet. The pressure during the whole mission shows a clear relationship with the orbiter's velocity vector. When the gauge is screened by the orbiter from the relative flow of the upper atmosphere (wake condition), the pressure is constantly low, but much higher than that of the model atmosphere. At present, it is best explained by gas leakage from Spacelab or some of its instruments. When the gauge is open to the flow (ram condition), the pressure is linearly related to the cosine of the incident angle and has a maximum at normal incidence. The maximum is more than one order of magnitude higher than the model pressure. This is interpreted as escape of incident atmosphere from the Spacelab's surface with thermal velocity. |
