deployment Josh Kohut (re. leak):

Hi All,

Eli, Filipa, and I went through the glider to see if we could identify the
leak.
Here is a brief summary. We can fill in details after a little sleep.

1) We saw very little water along all the o-rings. There was more around
the forward o-ring.
2) There was no noticeable water inside the aft bulkhead or around the
payload bay.
3) We did see water on the inside of the nose with a salt water streak
running from the leak detect forward to the base of the buoyancy pump.
4) There was water along the seam between the nose and the buoyancy drive.
5) We put it back together, pulled vacuum and looked at the diaphragm with
the pump pulled in.
There was some noticeable wear and tear, but we did not see any holes.

We are happy to look more into this tomorrow after a little sleep. Right
now the glider is on the bench with an 8.7 vacuum. We will monitor this
tomorrow.

Oh we also wiggled the glider and got no errors for the fin motor. The fin
seemed to move through the angles just fine.

Thanks,
Josh

Apologies on abort forgot to change number of waypoints in queue.

deployment Battery situation looks better, stabilizing a bit. Turned science back on on the upcasts.

deployment Slowed glider down and turned optics off on upcast until we can get a better feel for battery curve... dropped fast to 12.5 but looks like its doing to hold steady, we will see.
