Problems: 

There has been a water leak somewhere, and 3 of the monsoon crates (1, 2 and 3) went off. The operators are working to maintain the crate 4 coole. This is the crate that controls the focal plane temperatures.
They will apply a temporal fix now, and most probably the mechanics will fix the leak tomorrow.
