MFD Status Report
August 10, 16:00 CDT
The second test run of the Manipulator
Flight Demonstration (MFD) test aboard STS-85 started on August 10 5:06 CDT.
After the MFD system activation and checkout, the arm was released from the Arm
Hold and Release Mechanism (AHRM), and was operated by Mission
Specialist Steve Robinson to detach the simulated Orbital Replacement Unit
(ORU), then operated the arm to evaluate the functions and performance of the
arm while grappling the ORU, and finally reattached the ORU to its pallet. Followed
by a lunch break, Mission
Specialist Jan Davis swiched over to operate the MFD arm to demonstrate the
functions of door opening and closing. The crew commented on the operability of
the MFD arm as "very smooth". The third test run of the MFD is scheduled to start
tomorrow 6:31 CDT.
The Evaluation of Space Environment and Effects
on Materials (ESEM) has been conducted for a total of approximately 15 hours,
and will continue to acquire data on the space environment.
