Bob,

I'm seeing the data on the SAVE RAFT website - internal temperature is
quickly rising - it is now just above 20 deg. C. I also notice that the
solar current is dropping; I wonder if this is because of clouding of the
epoxy holding the solar panels as they heat up, or meet with more oxygen
ions as the descent continues.

Just saying...
