OPERATIONS

Today's communications sessions indicated the crew's positive attitude and readiness to get the Mir operations back on track.

The crew is working toward a Spektr internal EVA on July 11, with an EVA dry run on July 9. Mike will assist in all EVA preparations and procedure review activities as required. Science operations will be scheduled to allow for completion of all required pre EVA activities.

In support of EVA preparations, the Priroda Module will be powered down on July 4 and the hatch will be closed on July 9. Likewise the Kristall and Kvant 2 modules will be powered down and hatches closed on the same date. This will allow for an EVA dry run with the Mir transfer compartment in the configuration anticipated for the EVA. NASA/Mir Science operations are being scheduled to support these plans.

EXPERIMENT HARDWARE

BEETLE

The Beetle experiment was relocated to the Kristall Module today and repowered from the Base Block. This experiment should not be impacted by the Kristall hatch closure and subsequent EVA activities.

GREENHOUSE

Several meetings and telecons were conducted in TsUP today between the MOST and joint investigator team to define the plan of operation for Greenhouse over the next several weeks. The investigators have decided not to perform a chemical fixation and will only perform a dry fixation if it appears that the plants are in the appropriate stage of development. Greenhouse received an eight hour lighting period today. Mike reports the plants are green and not yellow.

SAMS

Mike was asked to stow the SAMS disk in the Soyuz Module for expedient return; however, Mike reported that he was NOT able to capture the Progress collision with the SAMS experiment support Module. He stated that the SAMS was powered on, but the data acquisition mode was turned off to save disk stowage space. He was going to turn on the data acquisition prior to docking; however, he stated that docking occurred sooner than expected.

DCAM/DEWAR

Mike confirmed that the DCAM trays are in the Priroda Module. Dewar is in the Docking Module.

SMP/MEDICAL

Mike reported the following data for the Ethylene Glycol Samples:

Time Location Level

1730 DMT Base Block 3 mg/m3 (1.2 ppm)

Kvant 15 mg/m3 (6 ppm)

PUBLIC AFFAIRS

No public affairs activities were conducted today.

RESUPPLY ITEMS

All of the materials requested by Mike have been flown to Baikonur along with all hardware and consumables required for the Spektr internal EVA. Special instructions were provided to Mr. Lebedev on the care and packaging of the medical kits. An additional package of EVA visor anti-fog wipes will be flown to the launch site at a later date. The Progress-M 35 launch is now scheduled for July 5 with a docking on July 7. The items delivered for the Progress include:

Emergency Medical Kit (EMK)

Medications and Bandages Kit (MBK)

MSMK Checklist

EVA Tools (connector tool and flashlight)

Personal Hygiene Kits & supplies

AA batteries (100), spot meter batteries (2), databack batteries (8)

MIPS (Optical disks (4), MIPS-2L hard drive and 2C PCMCIA hard drive)

COSS (Hard drives, disks, video tuner card, cables and memory Module)

Psych support package

COMMUNICATIONS SUMMARY

NETWORK STATUS

The network was asked to stand down from its emergency support posture based on good attitude control via the gyrodynes. It was confirmed with the GSFC Network Director that 24 hour 7-day/week support is routinely available from Wallops and White Sands for Mir VHF1 and Soyuz VHF communications. This means that the Wallops and White Sands stations are able to support two way communications with Mir and Soyuz on all pass above their local horizons. Mir flight management has been briefed on this capability.

MOTION CONTROL

A magnetic suspension unit changeout was performed on gyrodyne 1 in Kvant-2 yesterday and it was spun up today, bringing the total number of operating gyrodynes to 11.

LIFE SUPPORT

(Note: According to Mr. Antoschechkin, the statement by Mike Foale quoted in the MD 45 Status Report that the "older" Elektron was being used was erroneous.)

The Elektron in Kvant-1 (new unit brought up on STS-84) was started at 11:00 DMT. Mr. Antoschechkin informed us that it will be limited to about 10 hours/day operation because it is powered from the core Module and running it longer than that would require pointing the station +X axis toward the sun for long periods of time to maintain optimal power. This attitude would overheat the Kvant-1 docking Module and potentially overheat Kvant-1 systems (gyrodynes, Vozdukh, etc.) due to the absence of a docked Progress. With Elektron operating at 10 hours/day, the crew will have to burn two solid fuel oxygen canisters every other day. The problem of overheating Kvant-1 with the +X axis pointed toward the sun will be eliminated with the arrival of the next Progress.

The urine water recovery system (SRV-U) was restarted today at 11:07 DMT, but with the distillator turned off to conserve power in Kvant-2 for gyrodyne operations. The system is putting urine into the EDV normally used for urine residue (brine) rather than distilling the urine.

Mr. Antoschechkin informed us that the crew will be working on the condensate recovery system (SRV-K2). This will involve bypassing a filter in one line, bypassing a failed pump in another line and then cross-strapping the two lines together.
