STATUS REPORT: HST First Servicing Mission
As of Mission Elapsed Time: Day 5, 11:00
(15:30 EST 12/07/93)
K. Carpenter and M. Niedner
HST Project Science Office
NASA - GSFC
Accomplishments/Major Events:
pre-EVA: launch, rendevous and grapple of HST
EVA #1 - restoration of full gyro redundancy by replacement of RSU's 2 & 3
and ECU's 3 and 1. We now have 6 fully functional gyros.
Replacement of 8 fuse plugs.
Solar array preparations for EVA 2.
EVA #2 - jettisoning of +V2 wing of Solar Array - I
installation of both wings of Solar Array - II
EVA #3 - replacement of WF/PC I with WFPC 2
new magnetometers (MSS1 and MSS2) piggybacked onto
original magnetometers and tied in electonically to
replace function of originals.
SI Status:
WFPC2 has passed early functional tests, it is warm for decontamination
and is in operate mode
GHRS is in 3-DEB warm-up mode
FOC remains in Hold Mode on side A
HSP remains in Safe mode
FOS has low voltage on, red side
Upcoming Events:
EVA 4: Replacement of HSP with COSTAR
Installation of 386 Co-processor
Problems/Concerns:
During installation of the new magnetometers, pieces came off of the
old MSS2. Therefore a new task will likely be added to the mission -
both of the old MSS's will be wrapped in mylar blankets taken off
of the radial SIPE (Science Instrument Protective Enclosure) to ensure
no pieces will come off at a later date and cause problems for HST.

STS-61
CSR DAILY REPORT
(6 A.M. CST 12/6/93 TO 6 A.M. CST 12/7/93)
HUBBLE SPACE TELESCOPE (HST)
During flight day 5 crew sleep, the remaining two gyros successfully completed
functional testing. All six gyros have been verified to be operational.
A flawless installation of the Wide Field/Planetary Camera-II (WF/PC-II)
highlighted the third extravehicular activity (EVA) to service HST. WF/PC-II
successfully completed an aliveness test. WF/PC-II functional testing will be
completed on flight day 6. The original WF/PC was secured and stored for
return and post-flight analysis.
During Magnetic Sensing System-2 (MSS-2) replacement operations, the crew
recovered two loosened sides from the original MSS-2 instrument. A tiger team
has been formed to determine if corrective action repairs are necessary. After
installation, both new Magnetic Sensing Systems passed their functional tests.
IMAX CABIN CAMERA AND IMAX CARGO BAY CAMERA (ICBC)
The crew reported changing the ASA 23 (exterior) film for the second time.
This means that they are starting the third roll, which agrees with electrical
current traces monitored on the ground. These traces had indicated three
possible in-cabin camera shots taken during EVA #2. Since the crew reported,
electrical current traces have indicated 9 more shots by the cabin camera.
There are no IMAX In-Cabin Camera or ICBC problems or issues at this time.
DTO's (Development Test Objectives)
DTO 648 Electronic Still Camera Photography Test (with downlink) - Performing
as planned.
DTO 656 PGSC Single Event Upset Monitoring (Configuration 1 and 2) -
Performed as scheduled.
DSO's (Detailed Supplementary Objectives)
DSO 624 Cardiovascular Responses to Submaximal Exercise - Was scheduled
and assumed completed.
