Summary
This is an additional trip right before Hank sends up the instrument comparison at Vaira. This mission of the trip is to swap newly calibarated Li-7500 at Vaira and clean up the surface of radiation sensors. Make sure everything works well for the comparison.

Somehow the power connections between power line and Li-7500 was loose when I got to Vaira. So, there was no power for the EC system about 3 days. Swap Li-7500 on Vaira,
Floor and Tower site worked well.
