At approximately 2108z on May 5, 2001, the final command to
turn-off the GOES-2
communications subsystem was executed by the NASA/Kokee Park
Geophysical Observatory.
This followed Stage Six of the de-orbit maneuver which indicated
all fuel had been consumed.
Thruster temperature increases were minimal, tank pressure
decreased to 53 psi. The spin rate
and period remained steady. All of these factors led the
engineering and navigation team present
at Kokee Park and Suitland to conclude there is no further action
needed. After 24 years of fuel
accounting (estimated +/- 11 lbs error), the actual fuel
remaining was within 1 lb of the estimate!
The new orbit will be received over the next month (via NORAD).
Great job by all involved.

This morning, GOES Operations were successfully transitioned from
the LCR in the New SOCC
to the new GOES Operational area. Last week, the new GOES
Operations area was
successfully utilized for GOES-M end-to-end testing and a GOES-M
launch simulation from the
Cape. So far, no impacts to data have been observed.

POES

No change in the status of the POES spacecraft.

NOAA-16 rev 3178 / W at 1816z on May 4: Load failure on first
attempt from schedule. Second
load try was successful, but most of GAC4B was lost during the
“cleanup” process after the new load was installed.
100% of GAC4B was successfully recovered
one rev later from FCDA at 2009z.

NOAA-14 rev 32709 / W at 1016z on May 5: GAC1A was received noisy
from spacecraft with
99% of the expected data recovered. No retry necessary.

NOAA-15 rev 15486 / W at 1131z on May 6: GAC3B received noisy
from spacecraft with
97.6% of the expected data recovered. No re-ingest required.

NOAA-14 rev 32726 / F at 1503z on May 6: GAC2B received noisy
from spacecraft with
97.4% of the expected data recovered. No re-ingest required.

NOAA-11 rev 65055 / F at 2102z on May 6: STIP3B received noisy
from spacecraft with
97.6% of the expected data recovered. No re-ingest required.

NOAA-16 rev 03210 / F at 0052Z on May 7: GAC1A did not lock on
the bit sync or frame sync
on the first playback from the spacecraft, so it was forward
played and replayed during this pass
for a complete recovery. Post-pass IMUX problems caused the crew
to be unsuccessful in the
attempts to transfer any data sets after the pass. The oncoming
crew worked for hours to fix the
IMUX and all “lost data” was finally transferred
successfully starting at about 0730z. The relief
crew took the data from tape and dubbed it back to the hard drive
to facilitate the successful
transfers.

POES operations were nominal over the past 72 hours.

DMSP

No change in the status of the DMSP spacecraft.

DMSP operations were nominal over the past 72 hours.

GOES

No change in the status of the GOES spacecraft.

GOES-2 was successfully deactivated on 2108z on May 5, 2001.

At 1427z and 1430z on May 4, GOES-10 frame breaks were observed
and attributed to high BER
at the CDA (unknown source).

At 1941z on May 5, a GOES-8 frame break was observed and
attributed to high BER at the CDA
(thunderstorms at CDA).

At 1250z on May 6, a GOES-8 frame break was observed and
attributed to loss of signal
synchronization.

At 2345z on May 6, a GOES-10 frame break was observed and
attributed to high BER at the
CDA (unknown source).

GOES operations were nominal over the past 72 hours.
