本文报告了在中段空间实验（MSX）使命的早期操作阶段从中性质谱仪（NMS）获得的测量结果。在这一阶段，航天器周围的主要物质是氩，它来自用于冷却SPIRIT III孔门的固态氩制冷剂的升华。主要的污染物种类是水蒸气，从NMS视野内的航天器表面排出。有机物质一般低于检测限。在部署期间，检测到可能来自NMS覆盖层的无机物质。除了在轨的结果，操作和规格的NMS简要介绍沿着地面校准数据。
Results are reported on the measurements obtained from the neutral mass spectrometer (NMS) during the early operations phase of the midcourse space experiment (MSX) mission. During this phase the dominant species present around the spacecraft was argon that originated from the sublimation of the solid argon cryogen used to cool the SPIRIT III aperture door. The major contaminant species was water vapor which outgassed from spacecraft surfaces that were in the NMS field of view. Organic species were generally below the detection limit. Inorganic species were detected that may have come from the NMS cover during deployment. In addition to the on-orbit results, the operation and specifications of the NMS are briefly described along with ground-calibration data.
