NASA Space Station On-Orbit Status 16 April 2005

SpaceRef note: This NASA Headquarters internal status report, as presented here, contains additional, original material produced by (copyright © 2005) to enhance access to related status reports and NASA activities.

All ISS systems continue to function nominally, except those noted previously or below. A short day for the crew (7h 45m), to be rested for the 10S docking tonight. As of ~11:00am EDT this morning, the ISS has circled Earth 36,600 times since launch of FGB/Zarya, covering a distance of 1.549 billion km (969 million miles) or ~6 times the distance to Mars and back.

Chiao and Sharipov performed a number of tasks in preparation for the arrival of 10S and its three-man crew, before turning in again at 9:45am EDT.

In the Lab module, Dr. Chiao powered up the HRF GASMAP (Human Research Facility/Gas Analyzer System for Metabolic Analysis Physiology) and its laptop for the last routine 30-day health check for Increment 10. Later in the day, the equipment was turned off again.

Also on the HRF laptop, the Science Officer performed file management activity on the hard disk to prepare it for an ADUM (Advanced Diagnostic Ultrasound in Micro-G) data collection session scheduled for next week.

FE Sharipov charged the battery of the second digital video camera, DVCAM PD-1P, to prepare it for covering the hatch opening ceremony at 1:10-1:30am EDT tomorrow morning, to be downlinked for public viewing.

Salizhan completed another preliminary 55-min training session in the “Chibis” ODNT suit as part of his preparations for returning into gravity. Leroy Chiao provided assistance. [The below-the-waist reduced-pressure device ODNT (US: LBNP) in the “Chibis” garment provides gravity-simulating stress to the body’s cardiovascular/circulatory system for reestablishing the body’s orthostatic tolerance (e.g., the Gauer-Henry reflex) after the six-month stay in zero-G.]

Sharipov conducted the daily routine maintenance of the SM’s SOZh environment control & life support system, including ASU toilet system.

Chiao also completed the regular weekly maintenance reboot on the operational PCS (portable computer system) laptops and the bi-monthly restart of the OCA comm router laptop.

The Elektron has been commanded off, per plan, after operating nominally in the 64-amp mode yesterday. At mid-day yesterday, the ppO2 (oxygen partial pressure) was 166.8 mmHg/Torr, resulting in a 21.8% concentration level. The cabin total pressure was 14.8 psi (766 Torr).

In preparation of Roberto Vittori’s crammed VC8 “Eneide” science program, Sharipov connected the AQUARIUS-B payload to a power outlet in the Service Module (SM), setting it to +37 degC, relocated the Biotechnology (BTKh) Luch-2 experiment from the Cryogem-2 in the SM to the DC1 docking module near the Cryogem-03 cooler, and activated the KUBIK-AMBER hardware, setting it to a temperature of +28 degC. [The VC-8 program, running from 4/15 to 4/25, consists of 23 ISM “Eneide” (ESA/Italy) experiments and PAO & “symbolic” events. VC8 experiments will use hardware that will be delivered on 10S specifically to support this projec7t as well as equipment already on board the ISS Russian segment (RS), including the AST spectrometer for the LAZIO experiment, the CRYOGEM controlled-temperature containers, the KUBIK-AMBER thermostat for the CRISP-2 (Crickets in Space) experiment, and the AQUARIUS-? thermostat container used in the experiments FRTL-5 (Radiation Effects on Rat Thyroid Cells) and BOP (Human Bone Osteoblast Physiology). In addition, Soyuz ???-6 will deliver two IBM A31p ThinkPad-based laptops, one of which will be used in the “Eneide” experiment, the other in the LAZIO, E-NOSE, and HBM experiments. Photo and video imaging will be performed using a Nikon D1? digital camera and a DSP150P camcorder delivered by Soyuz-???6.]

Soyuz TMA-6 (10S) with Expedition 11 crewmembers Sergei Krikalev & John Phillips plus Italian VC8 cosmonaut Roberto Vittori continues to catch up with the station for the docking tonight at 10:19pm EDT (5:19am DMT/Moscow on Sunday). [FD2 activities, starting yesterday with crew wakeup at 1:30pm, included systems & crew health status reports to TsUP, preparation of the Soyuz Orbital Module (BO) for the subsequent rotational (RUO-2) & translational (RUD-2) hand controller checkouts over RGS (Russian ground sites), building attitude for and executing the DV3 burn at 9:59pm last night, placing Soyuz back in its sun-spinning “barbecue” attitude (ISK) and swapping CO2 absorption cartridges in the BO. Today, FD3 activities began at ~12:50pm with crew wakeup after their second sleep period. Throughout the wake periods in free flight, Vittori conducted experiments of his VC8 program. Later today, at ~5:50pm, right after the Orbit #31 RGS (Russian ground site) pass, the crewmembers will put on their Sokol suits and PKO biomed harnesses, transfer to the Orbital Module (SA), activate its air purification system (SOA) and close the hatch to the Descent Module (BO). After the DV4 burn tonight at 8:24pm, activation of the active Kurs-A system on Soyuz (8:40pm) as well as the passive Kurs-P on the SM (8:42pm), the DV5 burn at ~9:08pm (at ~101 km range) and up to three additional adjustment burns during automated rendezvous (starting at 9:37pm), station fly-around to align with the DC1 port will begin at ~10:00pm, followed by station keeping at ~10:09pm. Final approach, initiated at 10:10pm, will be concluded on Orbit #34 by docking and Soyuz hooks closure, at which time the ISS maneuvers from temporary free drift back to earth-“fixed” LVLH TEA (local vertical/local horizontal torque equilibrium attitude), reverting to U.S. CMG control. Since orbital sunrise is at 10:01pm, the final approach and docking phase will take place in bright sunlight.]

After its current sleep time, which ends at 6:15pm tonight, the ISS crew will perform final steps in preparation for the Soyuz TMA-6 arrival. Primary activities by ground-command and by the crew will include:

  • Configuring the US P6 solar array BGAs (Beta gimbal assemblies) to autotrack the Sun (6:15pm);
  • Handing over attitude control to RS motion control (6:20pm);
  • Powering up the Lab RWS (Robotics Work Station) and the SSRMS (Space Station Remote Manipulator System) on the prime string for covering the Soyuz docking with its external cameras (6:35pm);
  • Setting up the onboard video and A31p laptop connection for linking the RS event to the US segment and Ku- and S-band assets (7:35pm);
  • Relaying Soyuz voice comm link to the US S-band for downlinking during the rendezvous, starting at ~100 km range (9:08pm);
  • Feathering the P6 solar arrays 2B & 4B;
  • Starting to collect structural vibrations data with the SDMS (Structural Dynamics Measurement System) on the S0 truss for five minutes during the docking;
  • Monitoring the approach and docking (10:19pm), and
  • Turning the TVS video system off at ~10:25pm.
