UPDATE # 14 - February 27, l998

PART 1: No more changes!
PART 2: Better get set! BAW is coming
PART 3: WITN career segment chats
PART 4: Demonstrating that science is fun
PART 5: All you ever wanted to know about waste trays and more
PART 6: Subscribing & Unsubscribing: How to do it!


NO MORE CHANGES!

In three words that was the tone of the last Payloads meeting. Actually it
was the shortest of all the meeting I've attended, and I think, counting
me, there were only about six people there! Most of the rest are either at
Johnson or Kennedy Space Center doing testing and preparations for the now
officially delayed launch. (In case you missed it, STS-90 has been
rescheduled for an April 16 launch.) One of the key persons who gave a
report was Marilyn Vasques, Logistics Operations Manager. Hers is one of
our newest bios online at: http://quest.arc.nasa.gov/neuron/team/vasques.html

But let me try to give you my version of what Marilyn does.  Imagine an
orchestra conductor trying to prepare for a concert with a short timeline
in which the players are from all over the world, the instruments have not
yet been ordered, let alone shipped and received, and the chairs and
platform have not been set up. The only thing the performers have going
for them is that each knows his/her part.

This is only a tiny idea of what Marilyn confronts since each "player" in
her "orchestra" needs a lot more than one instrument. Marilyn has to be a
very organized, energetic, emphatic but calm person to pull it off! Her
role alone gives good reason for the "No more changes" theme the morning
took. Notwithstanding that, Marilyn has a "magic hat" (a box of items that
has been assembled from her years of experience) that will allow her to
pull off some last minute miracles. Marilyn shared with me some wonderful
stories of things that can happen when human disconnects cause "sour
notes." I hope to have them ready to share with you soon.

In an attempt to keep you in touch with  the complexity of the Neurolab
process, I invited myself to a meeting entitled: Neurolab Middeck and Cold
Stowage Preship Review. The bottom line is: not all of this process is as
exciting and fun as the crew training Dave describes in Part 4! Amazingly
a certain sense of humor was maintained as "we" plowed through some 40
plus pages of status review, and then we went into the HiBay, a place
where the items to be shipped were displayed on a table, each packaged and
labeled for easy identification. I even saw a package of labels labeled
"labels" (well, you get the picture!)  See more about my visits to HiBay
in Part 5 below.

Your NeurOn pal,
Linda

BETTER GET SET! BAW IS COMING

Brain Awareness Week is March 16th, and we have a really cool way to bring
a neuroscientist into your classroom to do some experiments with your
kids! Join us on Wednesday, March 18 at 10:00 pacific time, 1:00 eastern
for a live interactive program on Learning Technology Channel (part of
Quest's bag of tricks). Here's the deal:

Dr. Eric Chudler from the University of Washington will be online with us
remotely from the classroom of Kristi Gustafson in North City Elementary
School, I will be in the LTC studio, and you, hopefully, will be in your
classroom all ready to participate! We will do three experiments together
and then discuss the results online. Here's all you need to do before

DEMONSTRATING THAT SCIENCE IS FUN

by Dave Williams
January 20 - 23

This past week started with the second in the series of classes for Jay
and me as Crew Medical Officers. We had a chance to discuss the contents
of the shuttle onboard medical system (SOMS) kits and went over the
contents of all of the kits item by item. This was followed by training
sessions in the nominal and off nominal operations of the rotating chair
for the vestibular experiment. 

Wednesday brought a 4 hour simulator session to review the experiment
impacts of power losses in the Spacelab. We had a chance to review all of
the many payload powerdown procedures and spent a fair amount of time
looking at the electrical distribution diagrams for the Spacelab hardware.
We finished the day with a 2 hour brief on contingency deorbit procedures
in preparation for another simulation session on Thursday. 

Thursday morning Rick and I had a 4 hour EVA prep and post simulation in
which we reviewed the complete procedure for preparing and donning and
doffing our EVA suits. We spent approximately 15 minutes in the suits in
the airlock of the CCT in building performing comm and suit checks before
donning the suit. The session was a great review of suit procedures and
with both found it invaluable. 

Friday morning I had water survival training at the NBL. For this session
we don our launch and entry suits and are hoisted about 20 feet in the air
and then dropped into the water. We have to release our parachute, move
out from under it and then inflate and get into our life raft.
Fortunately, I was also able to record a short video welcome for the 7th
International Congress of Emergency Medicine while in my LES. The second
video session was to welcome students to the Ontario Science Center for
Engineering Week. It was taken with me hanging suspended above the water
and finished with me being dropped into the water after reminding everyone
that science is fun!! 

Friday afternoon, I gave a tour of the Spacelab to Canadian Space Agency
President Mac Evans and Minister Manley during which the Minister had a
chance to try the VCF experiment from York University and Bristol
Aerospace. The hardware functioned
flawlessly, and we are all looking forward to performing the experiment in
space. This weekend was spent studying orbiter systems and going over the
guest list and other administrative activities. Next week promises to be
equally exciting as Kay, Scott and I have become "Prime Escargots"!!

ALL YOU EVER WANTED TO KNOW ABOUT WASTE TRAYS AND MORE

Linda Conrad
February 17, l998

Somebody in Payloads is watching out for you! Last week I was sitting at
my desk answering email when the phone rang. It was Chris Barreras (our
in-house expert on the Great Habitat Debate) and his comment was, "We're
assembling the RAHF waste trays right now in the HiBay and it seems like a
NeurOn-type activity. Would you like to come watch?"  Would I! I dropped
everything, grabbed the digital camera and followed Chris' instructions to
find the HiBay.

My first clue that I was entering something special was the super-sticky
floor mat I had to step on to clean my shoes at the pass-protected door.
What I entered was a room that was, for all the activities taking place in
it, remarkably clean and organized. It's called HiBay due to the
hangar-like high ceilings and looks a lot like one of those warehouses you
see on TV, but those are usually dark and you can expect something awful
to be lurking somewhere. Hibay, on the other hand is brightly lit and
everyone in there is dressed in white.  I felt like I had been invited
into the inner sanctum!

That, of course, was one of the first things I had to do. Chris instructed
me to put down all my tourist-like paraphernalia (don't worry I got to
take pictures and will share them with you) and don a white smock. Chris
had gloves on, but since I had no intention of touching anything those
weren't necessary for me. I was then introduced to Lorenzo Salcedo, the
wizard of waste trays. 

Now those of you who designed habitats for the Great Habitat Debate and
participated in the chats with Mary Williams and Chris Barreras probably
have some ideas about the make-up of an RAHF waste tray, but I know I had
no idea how complex they really are! For those of you who are new to this
dialog, here's a question that was raised in the chat with Mary: How do
you keep the animals for the microgravity experiments clean? I imagine
that floating excrement would not be good for them. Mary's answer was: The
cage systems have fans that gently blow from the top of the cage into a
waste tray at the bottom. This keeps most of the excrement from floating
around in the cage. 

These chats led people to redesign their waste handling systems, but none
really included ALL the elements of the RAHF waste tray. So here goes:
I'll try to duplicate what Lorenzo demonstrated (pictures coming soon
online!) 

The waste tray itself consists of two light colored plastic frames that
corresponds in size to the length of the RAHF habitats. The lower housing
or frame is filled with a wire screen upon which Lorenzo had already
placed a "filtrete" which looks a lot like a thin sheet of  cotton secured
in place with red RTV sealant. By the time I arrived, these had been
drying for 12 hours lined up on a table.

The first step I observed was the placing of a thin charcoal filter across
the surface of the filtrete (again secured in place with sealant. Into the
other "frame," which had a plastic, more open mesh, Lorenzo placed
Bondina, a thicker, white cushion. The two frames (or sides of the
"sandwich", as Lorenzo called it) were then put together, indeed much like
a sandwich and screwed in place.

The next step was the "horseshoe." Again I didn't touch it, so the best I
can tell you was that it looked like stiff white plastic sheeting in the
shape of a horseshoe. Lorenzo coated a side with Tepelon, and then screwed
it in place around the waste tray. My understanding is that this horseshoe
helps to guide the tray into place in the habitat.

Then Ta-dah! Lorenzo held up the final product and smiled. As he worked,
he had told me that he was awaiting hopefully the day when this whole unit
will be made disposable. You see, not only does he get to put these
together, but upon return from flight, he gets to pull them apart for
cleaning! Ughhhh!
