Operations

Mike confirms, "there are no fixatives in SPEKTR".

Procedures/Timelines/English Form 24 - Timeline for today was received.

Experiment Operations

Window Survey - Mike reported that it took three hours to complete photographic survey of window #9 in Kvant II. This window had poor illumination. Due to Mir orientation, few of the windows on Mir are in full illumination. Mike suggests that over the next couple of days that he be scheduled for night phase photographic surveys with one window at a time.

Greenhouse - Mike reports that one or two seed pods are turning brown, withered and drying out about 1 to 2 cm from the tips.

Experiment Hardware

Greenhouse - Mike asked for and received permission to leave the greenhouse in the normal operational mode of 23 hours light and 1 hour of dark until the depressurized ingress to Spektr.

 

SMP/Medical

The Russian crewmembers completed several medical tests today in preparation for the upcoming EVA. The crew has returned to a nominal exercise pattern. Mike Foale was scheduled to complete the second day of the physical training cycle.

Mir Systems

Spektr

The crew reported during the 14:33 DMT comm pass that they could see "flakes" outside, and that this coincided with a "clapping" noise. Mr. Blagov informs us that they believe one of the Spektr external cooling loop accumulators was punctured when Progress hit the radiator, and that the leaking fluid is the coolant from the loop. Documentation for the other modules indicates that they used polymethyl silicone as a cooling agent, which has a freezing point of -110 deg. C. Potential implications for future Shuttle visits are being investigated. Ammonia from the radiator heat pipes may also have leaked.

Pressure Indication in Transfer Chamber

The crew reported that the manometer in the transfer chamber of the core module is reading about 100 mm lower than other pressure indicators in the vicinity. This is the same manometer that was previously used in the Kvant-2 airlock and caused the crew to open the EVA hatch before the differential pressure across the hatch had reached zero, resulting in damage to the hatch. The transfer chamber will be used as the airlock during the internal EVA into Spektr, so there is a question about what the EVA crew will use as a pressure cue prior to opening the hatch to Spektr.

Life Support/Thermal

Elektron was shut down at about 21:00 DMT last night (June 30) when the temperature of the Kvant-1 VGK coolant at the inlet to Elektron reached 25 deg. C, vs. the nominal 10-12 deg. C. Subsequent discussions revealed that the crew had inadvertently closed a valve connecting the VGK to the core module internal KOX-1V loop (the position of this valve is not visible via telemetry). As a result, coolant in the VGK was not being circulated into the core module loop and could not reject its heat into the core module external loop. When the crew reopened the valve, air that had been trapped in the VGK was suddenly introduced into the KOX-1V loop, creating a drop in differential pressure across the KOX-1V pumps. The crew will perform an air/water separation on the joint loop tomorrow morning, and Elektron will be restarted once functionality of the loop has been restored. The crew reported at 19:00 DMT that they had burned three solid fuel oxygen canisters today, as instructed.

 

Electrical

The core module batteries are fully charged, and the Kvant-2 batteries are almost fully charged.
