Tracking and Recovery Instructions:
Leave payloads intact in their landing configurations unless winds are dragging them about the country side.
There are some experiments that will deploy rovers. Be aware when moving through the fields and avoid stepping on them.
One experiment is going to attempt to orient itself upon landing. This payload is on EOSS-83 and special care should be given to attempt to preserve it's orientation.
