Atv # Notes and Comments: #4 While out on EVA, the back brake detached

from its place. We looked for the screws but couldn't find them. We

found a piece we believe is from the ATV (see attached photos). We

would like to know how to fix it, knowing we will be out of SIM

tomorrow and can go buy stuff in town.

Summary of Engineering activities: Routine check, filled the ATV's with gas.

Questions and Concerns to Mission Support:

Power: Still on Cat. It ran all day, non stop. Shannon will check it tomorrow.

open and close dome is at 14 volts
