Space Station Status Report for July 15

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 10/19/09 in gaps between the BZh Liquid Unit and the oxygen outlet pipe (filter FA-K) plus hydrogen outlet pipe (filter FA-V). [The CDR will inspect the filters again before bedtime, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

FE-4 Wheelock continued his second session of the medical protocol Pro K (Dietary Intake Can Predict and Protect against Changes in Bone Metabolism during Spaceflight and Recovery), with controlled diet and diet logging after the urine pH spot test. [Under Pro K, the crewmember measures and logs the pH value of a urine sample, 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 during the day.]

At ~3:55am EDT, Doug closed out the 24-hr urine collections for his 2nd (FD30) onboard NUTRITION / Repository / Pro K protocol and undertook the associated generic blood collection, with FE-2 Caldwell-Dyson assisting with the phlebotomy as operator. FE-4 then set up the RC (Refrigerated Centrifuge) for spinning the samples prior to stowing them in the MELFI (Minus Eighty Laboratory Freezer for ISS).…
