  • C&C MDM Recovery

Upon crew wake up today, the FCT was successful in recovering C&C 2. All I/O was inhibited to preclude unnecessary communications with the C&C. Communication with the OIU was re-established and data dumps were performed of C&C 2. Communication with the INT-2 MDM was reestablished. The FCT has performed a data dump of the N1-1 MDM and as of 10 am was not able to dump N1-2. Both NCS MDMs were in diagnostics, which may have caused by an ADA Exception set off by the C&C 2 time stamp (1992) when the C&C 2 was brought back up. C&C 2 is still on line and functioning nominally.

NCS MDM N1-1 MDM data dump performed. N1-2 data dump has not been perfomed. ODIN has attempted the dump several times. MER is has given the go power cycling the MDMs to recover them. N1-1 has been recovered. MER gave the go to power cycle N1-2. N1-2 is now in Standby.

Still looking at bringing up a second C&C MDM. Primary objective is to ensure the NCS is operating nominally prior to continuing with C&C backup MDM recovery.

 


  • CWC Water Fill

The MER is in the process and will complete the certification for returning CWCs filled with water in the MPLM. If the Shuttle request the return of a CWC full of urine, M. Suffredini and B. Gerstenmaier have accepted the risk of leaking urine in the MPLM and concur with transferring a CWC with urine in the MPLM.



  • MPLM reinstall may take place later today. The packing of the MPLM has been completed by both station and shuttle crews. SLP reinstall may take place tomorrow.


Upcoming Events for GMT 2001/116 Flight Day 8 (All times CDT)


  • FD 9 will be replanned due to C&C MDM problems.
