SMP/Medical
The crew requested to have their MK-12, Reflotron blood analysis data voiced up. They also suggested using venous blood instead of capillary blood for the next MK-12 session. The crew feels they would not have any difficulties drawing venous blood. Furthermore, the fingersticks during the last session caused sore finger tips for a couple of days.
During the last comm pass last night, the crew reported exercise was not performed since they were tired.

Private Family Conference
An audio only conference for all three crewmembers was scheduled in honor of Cosmonaut’s Day. Valery Polyakov, Alexander Polishchuk and Wendy Lawrence participated in the event.
Mir Systems
After a couple of automatic shutdowns of the Kvant 2 Elektron last night and four automatic shutdowns today, the ground experts told the crew they believe there is an air bubble somewhere in the system. The only way to purge the air is to continue turning the system on after it automatically shuts off. At the 16:35 DMT comm pass, the crew reported that the Elektron operated for 2.5 hours.
Following a crew call down of several environmental parameters, the crew was instructed not to use Progress oxygen today. (ppO2 = 160 mmHg)
