Biosphere Update

Day 27

Day 27
When you compare our biosphere today (Day 27) to how it looked on Day 18, you will notice that it has many more black spots in it.  There is a layer of dark gray fuzz on top of the mud layer.  The water is still clear, but there is a layer of gray powdery-looking stuff on top of the water.
