Space Station Status Report for August 24

All ISS systems continue to function nominally, except those noted previously or below.

At wake-up, CDR Skvortsov performed the regular daily early-morning check of the aerosol filters at the Russian Elektron O2 generator which Maxim Suraev had installed on 10/19 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [The CDR again inspects the filters before bedtime tonight, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

Upon wake-up, FE-4 Wheelock concluded his 5-day session of the medical protocol Pro K (Dietary Intake Can Predict and Protect against Changes in Bone Metabolism during Spaceflight and Recovery) after the urine pH spot test, his 3rd onboard run, with the final controlled diet and diet logging. Photo documentation was part of the activity. [Under Pro K, the crewmember measures and logs the pH value of a urine sample, to be collected the same time of day every day for 5 days. The crewmember also prepares a diet log and then annotates quantities of food packets consumed and supplements taken.]

Doug then underwent his 2nd (FD60) Nutrition/Repository/Pro K generic blood collection, in which FE-3 Kornienko assisted him with the phlebotomy as operator. Wheels set up the RC (Refrigerated Centrifuge) for spinning the samples prior to stowing them in the MELFI (Minus Eighty Laboratory Freezer for ISS). FE-4 also closed out his FD60 urine collections at about 3:00am EDT after completing the 24-hr protocol.…
