Space Station Status Report for July 2

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

Crew sleep cycle remains shifted to the right: Wake – 7:00am (reg. 2:00am), Sleep – 10:30pm (reg. 5:30pm) EDT.

At wake-up, FE-3 Kornienko 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). [FE-3 will inspect the filters again before bedtime, currently a daily requirement per plan, with photographs to be taken if the filter packing is discolored.]

CDR Skvortsov began the day by attending to the current experiment session with the Russian/German KPT-21 Plasma Crystal-3+ (Plazmennyi-Kristall/PK-3+) payload, activating the turbopump in the MRM2 "Poisk" module for keeping the vacuum chamber (EB) evacuated. The turbopump will be deactivated again before sleeptime, at ~10:25pm EDT. [Main objective of PK-3 is to study wave propagation and dispersion ratio in a dust plasma, i.e., fine particles charged and excited by HF (high frequency) radio power inside the evacuated work chamber, at a specified power of HF discharge, pressure, and a varied number of particles.]

FE-6 Walker continued her early-morning session with the Pro K protocol, with controlled diet and diet logging after the urine pH spot test.…
