NEAR Mission Status Report January 7, 2000
NEAR Mission Status Reports – http://near.jhuapl.edu
The NEAR spacecraft continued to operate nominally in Operational Mode
with Flight Computer #1 and Attitude Interface Unit #2 in control. All
instruments remained “ON” during this week.
NEAR is presently 52,990 Km from Eros (32,926 miles).
Operations conducted after the year-end transition resulted in no Y2K
related problems with either ground or flight systems.
The off-Sun pointing threshold was increased from 3 to 5 deg on 1/3/00 to
improve the S/C momentum control response time while Sun pointing. The
fanbeam downlink rate was decreased to 9 bps.
The NLR’s operating mode was promoted to a fully operational mode on
1/5/00. Sufficient operations were conducted to verify the proper routing
of NLR science data and full command capability. The NLR is now in the
proper configuration to support the re-test of the NLR Timing Test planned
Final preparations and testing of the command load to start on 1/17/00 are
nearing completion. This command load, to be loaded next week, contains a
second test of the Eros rendezvous sequence and a continuation of Eros
science and OpNav operations.
24 x 7 operations will begin on 1/10/00 with the start of routine Eros
Upcoming Spacecraft Activities:
The following are operationally significant activities planned for the
December time frame:
Jan 11 Begin Eros science operations and daily high gain data playbacks
Jan 11 Shorten S/C command watchdog timers to 3 days
Jan 14 Begin regular Eros OpNavs
Feb 2 Rendezvous maneuver
Feb 8 Rendezvous maneuver cleanup and momentum bias maneuver
Feb 14 Eros Orbit Insertion
