Narrative: I started sol 5 having a treat to my eyes in the morning when I opened the airlock to go to the GreenHab. The red mountains were covered with snow. I cherished the moment, took a photograph and headed to the GreenHab. The GreenHab still looked very green and fresh. The moisture levels for all the crops looked pretty much the same i.e. 75-90%. After taking the readings I headed back to the hab and worked on my research project. Aditiya, our crew astronomer, helped in finding some parameters to derive the equations of PET and ET . We obtained daily climate data from the Loa climate center in Utah as we found out it is the nearest climate center that has data for all the parameters we needed. Around afternoon we came up with an experiment that we can try to validate my research which is impact assessment of the GreenHab Hydrology. In the evening I went to the GreenHab to do my usual duties. Clare, our crew journalist and Rajvi, our crew engineer, joined and helped me harvest some ripe radishes, fully grown lettuce, kale and leaves of red cabbage and water the crops. By the end of the day I went to the science dorm to check on the pots that I left in the growth tent for my experiment, water ½ cup in the pots ( 4 in number), noted down the temperature (80.6 F) and called it a day.

Radish: 172g
