Preliminary timelines have been received for Wednesday and Thursday. EXPERIMENT OPERATIONS CGEL Mike told us again today that CGEL is producing counts of more than 3000. Mike also reported that during today's video run, when the light cover was on and it was totally dark inside, he could still see an image on the screen. The sample looked the brightest and the Bragg screen looked the second brightest. He believes the camera to be infrared and is worried that when the aperture is fully open, the video will be washed out. The ground then informed Mike that the camera is very IR. sensitive. Today's CGEL took Mike 4 hours. Most of it was general setup of photography. Mike could not find any crystals in sample 7, so he took photos of sample 5. He reports the process will take 1.5 hours just getting the setup right. If he has to tear down the photo setup each time, then it will probably add another hour. On sample 7, Mike reported that it had a cloudy colloidal suspension, but the colloid was spherical, kind of lumpy bits when compared to crystals. When shining a light straight through it, he said it had a lumpy appearance to the naked eye. When he shined a light from the side, he didn't see anything except a cloudy suspension. When asked how the electric mixer for CGEL is working, Mike reported it was OK for samples 6 and 7, but was tough on samples 3 and 4.

Mike then informed us he recommends ending pollination after today because there is only one flower, the rest are all siliques. Tomorrow he'll perform daily ops with photo, Thursday will be fixation. EXPERIMENT HARDWARE TEHOF Last Thursday the TEHOF was reported to be -15.4C. On Friday Mike was asked about the temperature and any TEHOF activity. He told us there had been no activity involving the TEHOF since the blood tubes were placed in it several days earlier. Mike then reported the temperature to be -15.6C. The next scheduled TEF/TEHOF call down is scheduled for this Thursday. SAMS Mike reported that SAMS ran all night. He changed disk 1 and turned over disk 2. SAMS was turned off after undocking at approximately 1400 DMT. EDLS The IFM was not performed today due to the delay in the Progress M undocking and the time required to complete the CGEL activities. Stowage/Transfer -No Issues SMP/Medical Mike performed a charge of the MAS battery in preparation for tomorrow's MAS sampling session. Mike called down the following values for CPA: CO 1.0 HCL 0.2 HCN 0.1 COMMUNICATIONS SUMMARY A/G with Consultants Group 15:01 - 15:08 CGEL count and video SAMS run and disk change Greenhouse data call-down CPA data call-down 19:37 - 19:44 CGEL comments and observations Report that EDLS IFM was not performed Video System - Nothing to report Altair Satellite System - Nothing to report Packet - Nothing to report. News Russian - None today English - Sent via packet. Ham Radio - Nothing to report. ISSUES None MIR SYSTEMS Life Support The crew located the cables for the new Elektron over the weekend, and performed a brief power cycle test on Sunday. During the test, the crew received an erroneous indication on their system status panel that the solenoid-operated hydrogen valve was open. The valve, which is used to dump to vacuum the hydrogen resulting from the hydrolysis reaction, should be closed, and a separate telemetry indication showed it was closed. The crew cleaned a connection the ground believed was causing the mal indication. Afterward the indicator blinked or periodically cycled. The next step will be for the crew to more thoroughly clean the suspect connection with an alcohol solution, but Mr. Antoshechkin stated that this will not happen until after all activities associated with the arrival of the next Progress have been completed. Progress-M34 Undocking The Progress undocking was delayed from 0840 DMT until 1320 DMT due to ground configuration problems. Because of this delay, Mir Flight Management decided not to perform the Inspector fly-around, as the fly-around for the later undocking time had not been simulated. Instead the Progress-M was separated by ground command and after one small separation burn, Progress M34 is station-keeping at a 30-35 km range from Mir. The redocking sequence will be executed tomorrow, per the nominal plan. After a three burn rendezvous sequence, the Progress-M will be redocked under TORU control. Docking is scheduled for 1220 DMT.
