OPERATIONS
Experiment Operations
Beetle Ventilation was performed today.
Experiment Hardware
PHOTO/VIDEO - Mike reported that he has "lots" of 70 mm film.
Mike confirmed NO FIXATIVE is in Spektr.
Mike also said that all WEK's were in Spektr.
Greenhouse
The greenhouse power reconfiguration and restart procedures radiogram was sent to the crew this morning.
The Greenhouse power cable was routed to the Base Block for power. Mike reported that he turned on SVET at 15:40 and ran Program 3. The lights were in the manual mode for 2 hours. The SVET is still on.
SMP/Medical - Nothing new to report.
Public Affairs Support
Mike Foale gave a status briefing of what happened just prior to the collision and what he has done since then. The briefing was played on NASA TV. On Sunday the crew will tape a message on how they are doing, that message will be replayed on NASA TV.

MIR SYSTEMS
Thermal Control
An air/water separation was performed on core module loop KOB-1 this afternoon after the differential pressure across the pumps decreased significantly. The differential pressure returned to normal following the separation. Mr. Blagov informed us that they plan to incorporate air/water separators in the ISS thermal loops, so that they won't have to plug in Orlan separators to remove air.
Life Support
The crew switched on the BKV-3 air conditioner in the core module this morning.
The ppO2 has decreased to about 145 mm Hg, so the crew will be burning one or two of the solid fuel oxygen canisters this evening. In addition, the crew cleaned the connectors of the Kvant-1 Elektron (brought up on STS-84) and performed a six-minute activation test at DMT 15:47. There was a repeat of a problem experienced early in the week, with the onboard indication for the hydrogen dump valve showing "open" while the telemetry indicated "closed". Other than that, life support specialists report they were happy with the results of the test, and the Elektron could be activated as early as Monday. The crew reported at DMT 17:25 that the unit had completed its auto purge following shutdown. The Kvant-2 Elektron cannot be activated due to the loss of power from Spektr.
Electrical
The core module batteries were completely charged as of this morning, and charging of the Kvant-2 batteries neared completion in preparation for the tomorrow's checkout and activation of the gyrodynes.
Motion Control
Attitude control continued to be maintained today by the station propulsion jets. Checkout of the gyrodynes is tentatively scheduled for DMT 03:00 tomorrow morning, and spin-up of the gyrodynes will be performed sometime tomorrow pending successful battery charging and completion of the checkout.
