Mission Name: Skylab CSM 3The purpose of this Skylab experiment was to assess the effect of space flight on endocrine-metabolic functions, including fluid and electrolyte control mechanisms. The data collected in support of M073 included -- daily body weight, accurate food intake (quantity and composition), accurate fluid intake, volume of a 24-hr urine output, samples of pooled 24-hr urine output (collected and processed inflight for return and postflight analysis), and preflight, inflight, and postflight blood samples taken for analysis. Urine was analyzed for sodium, potassium, aldosterone, epinephrine, norepinephrine, antidiutetic hormones (ADH), urine osmolality, hydrocortisone, total body water, and total and fractional ketosteroids. Blood was analyzed for renin, sodium, potassium, chloride, plasma osmolality, extracellular fliud volume (ECF), parathyroid hormone, thyro chloride, plasma osmolality, extracellular fluid volume (ECF), parathyroid hormone, thyrocalcitonin, thyroxine, adrenocorticotropic hormone (ACTH), hdyrocortisone, and total body water. All hardware used in M073 was a part of other systems. Hardware used in this experiment, along with the systems of which they were a part, included the urine measurement and collection system (a part of the habitability support system), the specimen mass measurement (a part of M074 (73-027A-26)), and the body mass measurement (a part of M172 (73-027A-32)).
