Spacelab Life Sciences 1 - Dedicated life sciences mission

The Spacelab Life Sciences 1 (SLS-1) mission is discussed, and an overview of the SLS-1 Spacelab configuration is shown. Twenty interdisciplinary experiments, planned for this mission, are intended to explore the early stages of human and animal physiological adaptation to space flight conditions. Biomedical and gravitational biology experiments include cardiovascular and cardiopulmonary deconditioning, altered vestibular functions, altered metabolic functions (including altered fluid-electrolyte regulation), muscle atrophy, bone demineralization, decreased red blood cell mass, and altered immunologic responses.

Experiment M405: Tri-axis flux gate magnetometer

A tri-axis flux-gate magnetometer was used on four Gemini spacecraft for determination of the magnitude and direction of the local geomagnetic field with respect to the spacecraft. Conclusions derived from the data are not only important to the proton-electron spectrometer experiment, but also are of significance to any directional charged particle experiments that may be conducted. Even though the Gemini spacecraft was not clean magnetically, the data could be reduced to a form that supplied directional information on the magnetic field in relation to the spacecraft. Stray fields were the result of spacecraft structure, not the result of current flows that were produced within the spacecraft electrical systems. Efforts were made to reduce spacecraft stray fields and to facilitate the acquisition of more accurate data.
