15:00 |
Post-launch |
TERRIERS is away, but having difficulties. See the
press release for more information.
|
| 5-17-99 |
15:30 |
Pre-launch |
The launch team has arrived at the hotpad.
The weather looks great and we are set for
launch!
|
| 5-16-99 |
15:00 |
Pre-launch |
We attended the FRR and LRR. There appear to be
no holds for launch. WE ARE A GO FOR MAY 17!
|
| 5-15-99 |
14:00 |
Mate to L1011 |
TERRIERS is mated to the L1011. We performed a
simulated arming sequence to ring out the GSE and COM lines.
The spacecraft is now set and secure for countdown on launch day.
|
| 5-15-99 |
06:00 |
Transport |
Transport from Bldg. 1555 to the Hotpad has begun.
The L1011 arrived yesterday evening. |
| 5-14-99 |
19:00 |
LMCM/Launch Rehersal/LPO Training |
Currently there are no issues keeping us from a 5-17-99 launch.
Today we participated in the mission rahersal. It was informative,
and there were no
outstanding TERRIERS issues. We ran the disarming procedure
with the LPOs to familarize them with TERRIERS. Tim also
attended this morning's LMCM in which there were no outstanding
TERRIERS related issues. |
| 5-13-99 |
08:00 |
Pre Transport |
Final touches on the fairing closeout continue.
We will transport the vehicle to the AIT today. A problem
with the L1011 was announced - horizontal stabilizer needs
to be replaced - and we may slip a day or two on launch.
|
| 5-12-99 |
09:40 |
Fairing Closeout |
Final touches on the fairing closeout continue.
We shipped out the secondary GS back to Boston and
we are preparing to support moving the vehicle onto the AIT
(transport trailer), tomorrow morning.
|
| 5-11-99 |
09:05 |
Fairing Closeout |
The fairing halves went on yesterday without any problems, and
it will be closed out today if we continue at the
current rate of progress.
The Titan has slipped, so barring any unforeseen problems, we
will launch on Monday May 17th!
|
| 5-10-99 |
07:55 |
Fairing Closeout |
This morning we will perform the fairing closeout procedures
on the satellite. We are still working towards a launch on the
17th, but have still not heard about the Titan. There was
a report that the Titan problem was software, which may
indicate a need for them to slip futher. This would clear the
way for us to launch on the 17th.
|
| 5-7-99 |
07:45 |
Fairing Closeout |
Completed a spacecraft check yesterday - all looks good.
We also participated in a Pre-LRR and found that there
are still some issues with the vehicle that are being worked...
We expect a data go from Flight Sim #4a later this
morning, so we'll start fairing closeout then. The latest
on the launch date is that they will make the decision on
the Titan IV on Monday. There are rumors that the
Air Force and Lockheed may not be comfortable with
the 15th. In any case, it looks like it will only be a
couple of days slip if they push the Titan to the 15th...
|
| 5-6-99 |
08:30 |
Flight Sim 4a |
Flight Sim 4a was completed yesterday and all indications
are that it went well. The data is being processed today and
we expect a "data go" tomorrow. The bad news for today is that
the Titan IV wants to go on the 15th and they are talking to
NASA about it now. I believe this would be a 1 week slip for
us. We continue to work for a launch on the 17th, however.
|
| 5-5-99 |
08:30 |
Flight Sim 4a |
Flight Sim #4a to go off today. Also, the Air Force has give
us the 17th on the range. Furthermore, with the failure of the
Delta III last night, it looks like the GOES will be delayed.
The 17th looks very good for launch now!
|
| 5-4-99 |
08:00 |
Pre Flight Sim 4a |
Still no firm launch date has been scheduled, due to conflicts
with the GOES launch, and we are still working toward the 17th. The MUBLCOM
crew arrived this morning to work the dreaded NEA harness and prepare for Flight Sim.
#4a - scheduled for tomorrow.
.
|
| 5-3-99 |
08:45 |
Post Anomaly |
No firm launch date has been scheduled, due to conflicts
with the GOES launch. We are still working toward the 17th. Flight Sim.
#4a is scheduled for Wednesday, and fairing closeout starting on Saturday.
Over the weekend we compiled a photo gallery page
and made some updates to the new web
site .
|
| 4-30-99 |
18:30 |
Standdown |
Dan Cotton arrives to cover the next couple of
weeks. He checks in with the spacecraft.
|
| 4-29-99 |
08:00 |
Standdown |
OSC has received a verbal go-ahead and is waiting on written
confirmation to proceed with Flight Sim #4a on Wednesday. Our
launch date is still waiting for Range confirmation. We anticipate
it will be near May 17. Our working schedule,
based on this launch date, has been updated below. Andy and
Sherri Stephan return to Boston.
|
| 4-28-99 |
10:30 |
Standdown |
We are still waiting for an official go-ahead from NASA,
and Range confirmation of a launch date before OSC can
release a new schedule.
|
| 4-27-99 |
08:15 |
Standdown |
NASA found an error in their model and corrected it. Their model
now matches the OSC model. A scheduling meeting is planned for
later today to work out a new launch date. It is anticipated to
be around May 18. We will update the schedule when it becomes
available.
|
| 4-26-99 |
08:10 |
Standdown |
TERRIERS is mated
to Pegasus
and waiting for NASA and OSC simulations of the WIRE anomaly to
agree. Our anticipated schedule has begun
to slide. We continue to trickle charge the power system.
|
| 4-23-99 |
09:00 |
Standdown |
TERRIERS is mated to Pegasus
and waiting for NASA and OSC simulations of the WIRE anomaly to
agree. Failure to come to agreement by today means we will
not be able to redo Flight Sim. 4 before Wednesday.
If it slips any further, it will begin to push the launch date.
We continue to trickle charge the power system.

TERRIERS is mated to Pegasus and awaiting a go ahead from
NASA. We continue to trickle charge the power system.
We are anticipating 2 weeks to get NASA and OSC simulations
of the WIRE anomaly to agree. This will push the launch date
to the week of May 16. A true schedule has not yet been determined.
|
| 4-19-99 |
08:10 |
Standdown |
TERRIERS is mated to Pegasus and awaiting a go ahead from

TERRIERS is mated to Pegasus and awaiting a go ahead from
NASA. We continue to trickle charge the power system.
NASA held a series of meetings today in which it was decided
that we should not mate the fairing until after meeting again
on Wednesday. The Wednesday meeting will allow NASA time
to review data from several models which are currently being
used to try to understand the yaw anomaly. As a result, it is not
possible to launch before the 22nd of April.
|
| 4-11-99 |
12:45 |
Standdown |
TERRIERS is mated to Pegasus and awaiting a go ahead from
NASA. We continue to trickle charge the power system. On
a more positive note, the leak in the roof is fixed.

18:19 |
Standdown |
We had started removing our protective covers in preparation for
fairing installation when Orbital was instructed by NASA to Standdown.
NASA Goddard is concerned about a yaw event seen during the WIRE
launch and has issued an "indefinite hold" until the issue is closed.
No work will be performed on the vehicle until Monday when Orbital and
NASA will regroup. The LRR Monday has been canceled and our April 18th
launch date is in question. We have rebagged the spacecraft and are
awaiting developments.
|
| 4-8-99 |
09:50 |
Fairing Closeout |
We started our fairing closeout procedure. We have removed all
test and RF GSE and installed the final flight high voltage safety
plug. Our next
communication with the spacecraft will be from orbit.
|
| 4-7-99 |
20:09 |
Post-Mate Ops |
Today we finished up our final payload checkout and prepared for fairing installation
Thursday. All systems look good.
|
| 4-6-99 |
08:30 |
Post-Mate Ops |
Today we started our post mate testing sequence. Testing was somewhat limited because
a series of hazardous vehicle operations to pressurize the RCS and HAPS meant that we had to clear
the high bay and leave the facility during those operations. All indications are that the
spacecraft is in good working order and we should finish testing Wednesday.
|
| 4-5-99 |
09:51 |
Post-Mate Ops |
TERRIERS sucessfully participated in flight sim #4 with no outstanding issues.
|
| 4-4-99 (Easter) |
16:30 |
Post-Mate Ops |
TERRIERS is mated to the Pegasus and awaiting flight sim #4.
|
| 4-3-99 |
13:30 |
Mate Ops |
TERRIERS is mated successfully to the Pegasus.
|
| 4-2-99 |
13:30 |
Pre-mate
Ops |
We participate in the TERRIERS pre-mate review. It is
accepted that that we have been ready to mate for over a week,
and that there are no liens against launch from the
TERRIERS spacecraft side.
|
| 4-2-99 |
11:40 |
Pre-mate
Ops |
A general email announcement implies incorrectly that
TERRIERS caused
launch delays. THIS IS UNTRUE. Integration has gone
extremely well thus far and we are ready to mate. It
is a harness on OSC's MUBLCOM secondary satellite that
has been holding up integration for the past week along
with the review of a vehicle anomaly on the WIRE flight.
In other news, we completed the tip maneuver of the satellite
in preparation for the mate. Operations were completed
inside an hour while MUBLCOM continues to check out their
harness.
|
| 4-1-99 |
10:40 |
Pre-mate
Ops |
MUBLCOM's harness is due back today. The new launch
date is still not completely set, but it looks like
it will be the 19th. They have stretched out the schedule
to accomodate the later date. OSC could make the 13th,
but are unwilling to risk the added cost of the L1011
for an extra week if we don't make it. See the
updated schedule below.
|
| 3-31-99 |
18:00 |
Pre-mate
Ops |
MUBLCOM's harness went out to Pomona, CA for re-rework.
OSC is requesting the 19th for a launch date from the
range, but NASA is still pushing for the 17th. This
depends upon how willing the range is to reconfigure
about 40 hours after the planned Delta II on the 15th.
The only operations we did besides battery maintanence,
were some flow gauge tests on our N2 purge system. They
were successful.
|
| 3-30-99 |
18:00 |
Pre-mate
Ops |
MUBLCOM's reworked harness failed initial tests and must be
reworked again. This will take 2 days and pushes TERRIERS
mating operations till Friday or Saturday. The launch
date has slipped from the 12th to a later date which is
still TBD. We may get word tomorrow....
|
| 3-30-99 |
07:45 |
Pre-mate
Ops |
OSC announced that the anomaly on WIRE's first stage
has resulted in a software change for the Pegasus avionics.
This will cause a 2 or 3 day delay. They are still looking
at the 12th for a launch date, but it is much less likely
now. We heard a rumor of the 17th, due to the Delta on
the 15th. Spacecraft mates will continue as scheduled.
|
| 3-29-99 |
18:00 |
Pre-mate
Ops |
We performed an Alk. Battery test successfully.
MUBLCOM's harness arrives and is being installed.
|
| 3-29-99 |
07:30 |
Pre-mate
Ops |
MUBLCOM's harness is due to arrive around 18:00 and will
be installed tonight. Testing on the harness will take
place tomorrow morning with mate to commence mid morning.
|
| 3-28-99 |
10:00 |
Pre-mate
Ops |
TERRIERS battery maintenance operations continued and
we verified our recycle procedure.
|
| 3-27-99 |
10:00 |
Pre-mate
Ops |
Only TERRIERS battery maintenance operations were carried out
today as we await mate.
|
| 3-26-99 |
18:00 |
Pre-mate
Ops |
Only TERRIERS maintenance operations were carried out
today as we await mate. MUBLCOM's cabling discrepancy
mitigation plan was completed and we are holding our launch
date of April 12th. MUBLCOM will send the affected harness
back to Dulles for rework over the weekend, reinstall and
do testing on Monday, and mate Tuesday. TERRIERS will then
mate on Wednesday. In the
mean time the vehicle ops that were scheduled for Monday
and Tuesday will go on as scheduled. The result is we
only lose a day which we will make up next Saturday. See
updated schedule.
|
| 3-26-99 |
10:00 |
Pre-mate
Hold |
The discrepancy in MUBLCOM's cabling is being reviewed
and it appears that we will not mate this weekend. The
current plan is to install shielding on one set of cables
and mate MUBLCOM this afternoon. This would be followed
by an intermediate test to verify there is no cross talk.
TERRIERS would then be mated on Monday. This plan is
currently being evaluated by NASA and OSC management.
|
| 3-25-99 |
14:00 |
Flt Sim #3 |
A discrepancy in MUBLCOM'S Non Explosive Actuator (NEA)
cabling is announced and is being worked. A mitigation
action has been developed and will be discussed with NASA
tomorrow. This will probably delay MUBLCOM mate until
late Friday or early Saturday. We also successfully
ran the full arming and recycle procedures proofing a
recycle mitigation procedure and the strip chart monitors.
|
| 3-25-99 |
08:00 |
Flt Sim #3 |
We verified that the recycle discrepancy was due to
a design feature of the power system
and developed 3 mitigating procedures. Two of the 3
procedures are tested. Also, we incorporated the
strip chart monitors into the arming procedure.
|
| 3-24-99 |
18:15 |
Flt Sim #3 |
Flight sim #3 was set up all day and began around 18:15.
The TERRIERS arming sequence runs smoothly, but the spacecraft
boots unexpectedly during the recycle procedure. We have
a working theory for the discrepancy and we will
review the events and schematics tomorrow. In any case,
the discrepancy does NOT pose a risk of radiation inside the fairing.

Functional |
Functional data is reviewed. All the data checks out.
|
| 3-23-99 |
17:00 |
Functional |
Functional test complete. Begin data review.
|
| 3-23-99 |
08:00 |
Functional |
Completed verification of TESS E and GISSMO electronics.
Obtained range certification, so we can now radiate
without getting clearance. In the afternoon Paul
Bernhardt verified CERTOs (radio beacon) functionality
in both the stowed and deployed configurations.
|
| 3-22-99 |
08:00 |
Functional |
Waited for range clearance and then continued with
instrument checkout. TESS A-D electronics were verified.
We also completed successfully an MSS phasing test.
Due to pulser cable problems, we were unable to complete
TESS E/G. We hope to finish on 3/23. Also Paul Bernhardt
arrived and joined the team for CERTO (radio beacon)
checkouts, which we hope to complete on 3/23 as well.
|
| 3-21-99 |
08:00 |
Functional |
Worked a GSE Tx problem all morning. After we fixed it,
we tested the HCIs, and started the instrument checkout.
We also performed a beacon antenna deployment test;
everything continues to check out.
|
| 3-20-99 |
08:00 |
Functional |
The remainder of the GSE is set up and we begin the post
ship functional tests. Various minor issues with the GSE
are uncovered and worked. We complete the low level
functional - all checks out so far. |
| 3-19-99 |
17:00 |
Lift |
TERRIERS is lifted onto the workstand and placed in the
clean room at building 1555. |
| 3-19-99 |
09:00 |
Unpack |
TERRIERS arrives at Building 1555 and is unpacked. All indications show that
TERRIERS had a smooth ride. The GSE is unpacked and we start
to set it up. |
| 3-18-99 |
20:00 |
Travel |
The TERRIERS integration team (Tim Cook, Andy Stephan,
Valerie Taylor, and Dan Cotton) arrives in Lompoc. |
