Restless sleep. Heavy head. Over the course of this flight we’ll get a serious education in self-restraint. I exercised on the treadmill and lay down to rest. I talk to my son and father — their photographs are beside me. Yesterday I said to Blagov: “Viktor, tell the leadership not to forget to include me in future flight programs.” He burst out laughing and said: “Well, I’ll be! I thought after the flight you’d take a rest and send space to hell. And you, Tolya?” “I want to fly too.” “Well then, I’ll pass the word.” Then he said we’re working without errors. If only he knew what it costs. From him I learned that Lyusya invited the TsUP guys over for her birthday. Good for her. She complements me well and smooths out the rough edges.

In the evening the condensate pump NOK-3 failed, installed in one of the cooling-drying units through which air is circulated. When moisture collects on its cooled porous walls, it is periodically pumped by automatic command into the water regeneration system. I decided to spin it by hand. Opened the port-side panel, and there on the cooling unit hangs an enormous blob of water foam. We switched to manual condensate pumping and reported to the ground.

Yesterday there was a meeting with the acrobats who became world champions in England. They performed several routines beautifully. I was honored in my capacity as chairman of the USSR Acrobatics Federation, which I’ve headed since the death of Vladislav Volkov.

Today I had the worst headache yet, to the point of nausea. All day I lay with the crown of my head pressed against the hull — it helps. I endured.

I observed auroras. Since deep antiquity they have struck people’s imagination with their majestic beauty. Today it is known that they result from charged cosmic particles penetrating to altitudes of about 100 kilometers in the polar zones, where the magnetic field lines form a kind of funnel, allowing cosmic particles to excite atoms and molecules of the upper atmosphere with their energy, causing it to glow.
