Today was the peak of the Lyrid meteor shower. We set up four cameras in the cupola simultaneously taking pictures. Gardener said there were places on Earth that were doing the same and all these pictures taken together will make a very interesting scientific data set. Since I had been placed next to a window, I was living through 16 periods of day-night every 24 hours. Jet-lagged, I could thus stay awake during the night and help in the observations.May 1
Gardener has been spending a lot of time playing a computer game. His computer is near our grow light so we can watch him. He plays in the morning before works starts and in the evening after work is over. He must find this relaxing. The game he plays is called “Catch the Dragon”. The best part about this game is that he does not have to put in any quarters.

Sunflower has brown patch. His leaves are covered with dry, dark blotches. He is not happy. Gardener says it looks like a fungus. I am afraid that if something is not done we are going to lose Sunflower. The crew medical kit is designed for animals not plants so there are no medications for this disease. Gardener is treating Sunflower with a disinfectant wipe that has an antibacterial agent called BZK (Benzalkonium chloride). We do not know if this is going to work. Our spacecraft is designed for animals so life can be a struggle for plants. On the frontier, the answers are not found in the back of the book and sometimes you have to venture into the unknown and improvise.

The BZK wipes seem to be helping. Gardener pats down Sunflower’s leaves every other day. He does this with the healthy new green ones as well. Sunflower is beginning to smile again. Broccoli and I seem resistant to this so he is not treating us.Don's blog also appears at airspacemag.com.

What a gardener will do for his plants. Just think what the pea plant would be saying, or Mendel.
Poor Sunflower. The BZK may be help. Looks a little like the normal aging I see on my sunflowers leaves that are near the bottom of the stalk. Love sunflower seeds so hope your feeling better soon.
Do you spray water on the leaves? That could be the explanation of the scorches.
I Hope that your sunflower is better :)
Hope the plant survives .. needs some sunshine and fresh air!
This is wonderful. It helps me feel like I am looking over your shoulders. Thank you for your wonderful accomplishments.
Dear Don Pettit,
I am a student of Aerospace Engineering, interested in math and languages and cultures and traditions. Could you please ask somebody in charge, maybe NASA Houston center or anybody, to turn the switch off thats manning my car driving missions? I will play some good blues and Jazz songs especially for you. Thanks a lot. Also, i will read your comments carefully, making my own sense. If it doesnt make sense, come back to Mother Earth and have the pleasure of scolding me. I am nice at taking that, and that only. Thanks much! Respect brvv. Will check the pics you have clicked.

I do not know your soil chemistry but I have never gone wrong w/ dish soap, vege oil, Superthrive, Miracle Gro, and a little Epson Salt all in a MG Feeder. Ratio is 1 feeder packet of MG,equal parts soap & oil, and directions on back of Epson salt. Remember Magnesium is essential for many plant process' and leaches thru acidic, sandier soils faster.
Copper &/or Sulfur application done proper will fix the fungus if needed
Hope this helps!

Human antifungal cream works on plant fungus, at least it does on mine on earth. But, be careful with it since it comes in a vaseline base that might make the leave not breathe (so apply very little, diluted with water on the wipe.
