International Space Station Daily Report
ISS On-Orbit Status 10/28/08 All ISS systems continue to function nominally, except those noted previously or below. Yuri Lonchakov set up the hardware for the Russian MBI-21 PNEVMOKARD experiment and conducted the session, his first, which does not allow moving or talking during data recording. Kononenko will have his fifth session tomorrow. The experiment is controlled from the RSE-med A31p laptop, equipped with new software, and uses the TENZOPLUS sphygmomanometer to measure arterial blood pressure. [PNEVMOKARD (Pneumocard) attempts to obtain new scientific information to refine the understanding about the mechanisms used by the cardiorespiratory system and the whole body organism to spaceflight conditions. By recording (on PCMCIA cards) the crewmember’s electrocardiogram, impedance cardiogram, low-frequency phonocardiogram (seismocardiogram), pneumotachogram (using nose temperature sensors), and finger photoplethismogram, the experiment supports integrated studies of (1) the cardiovascular system and its adaptation mechanisms in various phases of a long-duration mission, (2) the synchronization of heart activity and breathing factors, as well as the cardiorespiratory system control processes based on the variability rate of physiological parameters, and (3) the interconnection between the cardiorespiratory system during a long-duration mission and the tolerance of orthostatic & physical activities at the beginning of readaptation for predicting possible reactions of the crewmembers organism during the their return to ground.] The ISS crew continued to prepare for the STS-126/ULF2 mission by prepacking hardware for return in the MPLM (Multi-Purpose Logistics Module) Leonardo. FE-1 Lonchakov changed out the SRVK-2M multi-filtration unit and the Gas-Liquid Mixture Filter. Yuri also inspected the Sediment Trap Insert. [The SRVK-2M converts collected condensate into drinking water and dispenses the reclaimed potable water]. CDR Fincke downloaded heart rate and blood pressure measurements from the CCISS (Cardiovascular & Cerebrovascular Control On Return from ISS ) that had been collected passively over the past 24 hours using the Holter Monitor and Actiwatch. [CCISS provides data to support the study of the effects of long-duration spaceflight on crew members' heart functions and their blood vessels that supply the brain. This experiment is collaborative with the Canadian Space Agency.] As standard procedure for newly arrived station residents, Lonchakov filled out the questionnaire for the standard Russian biomedical Braslet-M/Anketa ("bracelet/questionnaire") test procedure. [If desired, the crewmembers may evaluate a number of "bracelet" cuffs for their usefulness in suppressing the adverse effects of micro-G for the "newcomer" aboard the station during the acute phase of adaptation to weightlessness, if there are such indications. The "bracelets" are compression cuffs attached to a belt and worn on the upper thighs over the coveralls, intended as countermeasures against the initial micro-G effects of blood filling (vascularity) in the upper torso (heaviness and blood pulsation in the head), facial puffiness, nasal stuffiness, painful eye movement, and vestibular disorders (dizziness, nausea, vomiting). They create artificial blood accumulation in the upper thirds of the thighs, causing some of the circulating blood volume to relocate from the upper body to the lower extremities, thereby (hopefully) correcting the adverse hemodynamic effect of micro-G and thus improving the crewmember's working capability. The actual compression cuff in the Braslet units is a combination of alternating multi-layer tensile and non-tensile elements, whose distension by body movements creates elastic forces that produce the necessary pressure on the body surface. The questionnaire lists bracelet types, days worn, cuff tension used, wearing method (on body or over clothing), thigh cuff positioning, etc.] HTV (IH-II Transfer Vehicle (HTV) Prox System Checkout: The JAXA (Japan Aerospace Exploration Agency (JAXA) Prox system checkout continued today with another checkout on the Range and Range Rate measurement function using the PROX link over a the Tanegashima Space Center Ground Station (TNSC GS) in Japan. HTV ground support reported that they got good range data today from both sets of tests. MSS (Mobile Servicing System) Operations: Today robotics ground controllers translated the MT (Mobile Transporter) from worksite (WS) 4 to WS6, and then on to WS7. The translation to WS6 was nominal and power & data redundancy was confirmed at Worksite 6. This fulfilled a portion of the ULF2 pre-launch checkout. The translation to WS7 was interrupted when the “+Y” worksite sensor at WS7 did not trip as expected. This was a recurrence of an anomaly which occurred when the MT translated to WS7 back on 2/1/08. The ground team recovered and completed the translation with manual commanding. Despite the resulting delay, there were no thermal issues and today’s ops were completed on schedule. Reboost: Tonight, the ISS is scheduled to perform a reboost using the 30P Rendezvous & Docking thrusters. This 0.55 m/s delta-V burn was to set up phasing for the STS-126/ULF2 and 31P launches. The reboost is scheduled for 9:13pm EDT. Significant Events Ahead (all dates Eastern Time, some changes possible.): |
