NASA Space Station On-Orbit Status 29 July 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.

MPLM Raffaello was successfully transferred from the Shuttle cargo bay to its berthing port at the Node.

FE Phillips, with Andy Thomas and Charlie Camarda, connected the N2 (nitrogen) transfer lines for pumping the neutral gas to the ISS, starting after EVA-1 tomorrow.

Sergei Krikalev meanwhile prepared the MPLM (multipurpose logistics module) vestibule in the Node, gathering equipment needed for the MPLM ingress activities.

For the MPLM transfer, John Phillips “walked off” the SSRMS (Space Station Remote Manipulator System) to Zone 4, i.e., the grapple fixture on the Lab, and then released its other end from the MBS PDGF-1 (Mobile Base System Power & Data Grapple Fixture 1) for the transfer.

After the successful installation of Raffaello at Node “Unity”, Sergei and Wendy Lawrence pressurized the vestibule and conducted leak checks.  The vestibule was then configured for ingress and the hatch to the MPLM opened at about 11:00am.

The FE than walked the robotarm off the Lab back to PDGF-1 for better video survey positions with the tip LEE (latching end effector) camera for clearance views in support of the Orbiter thermal protection inspections in the later part of the day.

While the OBSS inspections of the Discovery were going on, focusing on six “target” areas, John Phillips, assisted by other crewmembers, prepared the A/L C/L (Airlock crew lock) for depressurization by first cleaning out the A/L, then storing tools and equipment needed during the EVAs, some of them transferred fresh from Raffaello.  Later in the day, the C/L was closed off and depressed.   [The C/L will be used as an emergency ingress path for the spacewalkers after the Shuttle EVA hatch has been closed.  It will remain depressed for the duration of all three EVAs.]

John did the daily routine maintenance of the SM’s environment control & life support system (SOZh), including its toilet system (ASU) and the weekly inspection of the BRPK air/liquid condensate separator apparatus.  He also reset the SM pressure alarm (DSD).

Both crewmembers conducted their regular 2.5-hr. physical exercise program on the TVIS treadmill, RED resistive machine and VELO bike with bungee cord load trainer.   [Sergei’s daily protocol prescribes a strict four-day microcycle exercise with 1.5 hr on the treadmill and one hour on VELO plus load trainer (today: Day 3 of a new set).]

Afterwards, John transferred the exercise data files to the MEC (Medical Equipment Computer) for downlink, as well as the daily wristband HRM (heart rate monitor) data of the workouts on RED, followed by their erasure on the HRM storage medium (done six times a week).

At ~12:30pm, the Shuttle crew withdrew into the Orbiter, closing the hatch to the PMA-2.  The Orbiter was then depressurized to 10.2 psi in support of the EVA Prebreath protocol.

Sleep period began for all nine crewmembers this afternoon at 2:40pm EDT. Wakeup will be tomorrow morning at 12:10am.
