Wright: Today
is August 6, 1998, and we're speaking with Jim Wetherbee, with the
Shuttle-Mir Oral History Project. Thanks again for taking time out
of your schedule to meet with us.
Wetherbee: My pleasure.
Wright: We would like to visit with you specifically about your two
missions that you visited the Mir. All the missions were important,
but the first one that you did, I believe most people refer to it
as the "near Mir." Can you tell about how you first got
involved with that mission and some of your first experiences training
for it?
Wetherbee: Well, I'd love to. It was very interesting for me. At the
time that the flight crew was announced to fly on STS-63, I was up
in Crystal City, working in Washington, involved in the redesign of
the Space Station. At that time it was Space Station Freedom. The
flight, of course, STS-63, had already been being planned by the folks
down here in Houston and by the folks in Russia.
Before we were assigned, I think the Shuttle was intended to approach
no closer than 1,000 feet from Mir, and that was agreed to by the
Russians and the Americans. The flight directors were able to convince
the Russians, after they had that initial agreement, to let the Shuttle
go into 400 feet, and then even down to 100 feet.
So when the flight crew was announced, when I came on board with my
flight crew, we were supposed to go no closer than 100 feet from Mir.
The first thing I noticed when I asked about the flight, what our
job was going to be, and, of course, it was to test the procedures
and the ranging systems, the laser, the handheld laser, the automatic
laser, the radar. All of these systems give range and range rate information
to the target Mir, in this case and the camera system that was going
to optically give us information on the attitude misalignment, by
looking at the target. We were going to check out the procedures and
the flight profile and the directions that we were approaching.
The first thing I noticed was that the target, the visual target that
we'd look at, couldn't be used accurately until we got to about 30
feet. So the first thing I said is, "Well, instead of going to
100 feet, we will get much more if we go in to 30 feet." So I
first convinced the folks on the American side and they were agreeable
to letting us do that, but then the hard part came when my job was
to try to convince the Russians to allow us to go into 30 feet. And
if you remember, I mean, they had already given up a lot by saying,
"Okay, you can go to 400 instead of 1,000, and then 100 instead
of 400," so they were not very inclined to let us go any closer
than 100.
It resulted in a pretty interesting series of meetings and discussions
about why we wanted to get so close to their station, that is, of
course, a national asset, like our Shuttle. I never really talked
to them to see what they were really thinking about, but I'm sure
they were looking at some young kid off the streets who was going
to suddenly be flying a 100-ton vehicle within 30 [feet] of their
Space Station, and they didn't want to have any part of it. It was
risky enough for them, for little benefit, since we weren't actually
going to dock and transfer any people. We didn't have any docking
hardware.
We had one discussion in particular with Viktor Blagov, a good friend
of mine now, who was their I think he's their number-two flight director
over there. He was in charge of the mission at that time. We were
over in the Mission Control Center in Moscow, in Leningrad, discussing.
He pulled me aside. We had just recently we were there for some meetings,
which I forget what they were about, but he pulled me aside after
the meetings and said, "I want to ask you a few questions through
an interpreter." He wasn't speaking in English. I found out later
that he understood English, which I think put me at a little bit of
a disadvantage. I didn't understand any Russian, and so when we were
talking through our interpreter, he could listen to my English answer
and immediately formulate his next question while it was being interpreted,
and then he could think of what he wanted to ask and then ask the
question. And I couldn't think of my response until the interpreter
had translated the Russian into English, and then I immediately had
to come back with an appropriate response. So I felt like I was at
a little bit of a disadvantage.
But he's a man who understands the technical side of things. His job
was to balance the risk versus benefit, and although they didn't see
much benefit at the time, he wanted to ask me, "What is the benefit?"
I explained to him that this target that we were going to use could
be seen at the plan for Hoot [Robert L.] Gibson, who was going to
fly STS-71 a couple of months later, he was going to stop at 30 feet
and make that visual correction, based on what he saw, and I said
it would be very good if we could get in there and make that kind
of an assessment, to see whether or not the target was going to work,
and if it didn't, we'd still have time to change things.
I don't know that we convinced him that day, but in the next couple
of weeks, they finally said, "Yes, it's okay. You can go to 10
meters," was the final thing that we decided, using the metric
system, which is a little bit more than 33 feet, I think. I was happy
at that point because we were going to get to do a pretty valuable,
I thought, piece of test flying.
The other thing, I guess, that I thought was pretty interesting, later
on, we were in no, I'd better not tell that story.
Wright: Well, this is your oral history, so you can choose what you'd
like to tell.
Wetherbee: Apparently the Russians I don't know how it happened, so
I'll tell you. The Russians were a little bit concerned because, way
back in Apollo-Soyuz and I wasn't around then, due to various reasons
which I am not aware, but I think there were some pretty good technical
reasons at one of the dockings, not the first one, but the second
one, they hit the Soyuz a little a bit harder than they had intended,
I think, with the Apollo. The Apollo's a different system than the
Shuttle. It has a very high thrust-to-weight compared to the Shuttle.
I'm not sure of the specific details, but, anyway, they hit it a little
bit harder than they should have.
So the Russians we were there that night. We were having a dinner.
I guess it was a lunch, and I was with the senior people at RSC Energia,
the company that basically owns and operates the Mir. Of course, as
is the Russian custom, they were drinking some toasts and people were
having a pretty good time. And all of a sudden, the senior person,
who at the time, I didn't know, the senior person in the room at the
time turned and said, "I'd like to ask you a question,"
and of course, the whole room got quiet and they all looked at him,
this senior Russian official. And he said, "Tell me. Why did
they hit with four times the closing velocity than they should have
on Apollo-Soyuz?"
And of course, the rest of the room turned and looked at me to see
what my response was going to be, and I couldn't think of anything
to say. I wasn't around then, and the Shuttle's a completely different
system. The only thing I could think to say was, "Well, they
were just making my life difficult for me," and I didn't know
what else to say.
But the first discussion we had in the TsUP, in the Mission Control
Center, and then this discussion at the dinner, made me very aware,
if I wasn't already aware, that I now had a 10-meter limit and I was
not going to violate that limit by even a single centimeter. I was
going to go to 10 meters, 33 feet, and I wasn't going to be one centimeter
closer, because I knew both space agencies in both countries were
going to be watching as we approached on this flight.
Nothing much of note happened during the work-ups, other than we got
delayed about five or six months, I think. We had some trouble with
the payloads that we were flying in the Spacehab, so they decided
to delay our flight, which put us even closer to 71, to the one Hoot
Gibson was going to fly, which made it a little bit interesting for
us. There was less time to correct any problems if we saw any. But
as flights go, it was a lot of fun for me and for the crew to work
up and get ready to go fly in space.
You can always tell when an astronaut is ready to leave. Everybody
always wants to fly in space again, but they don't always want to
go through the one year worth of intense training and build-up in
preparation for it. I still have a lot of fun doing that and working
with the people, so it was a lot of fun getting ready to go fly.
We launched, and by the way, I had the first woman pilot at NASA with
me, Eileen [M.] Collins. She did a great job, and is probably the
nicest person I know, always in good spirits and good humor, and always
had a good time during the training and during the flight. We launched
on ascent, and as a commander flying with any rookie, you always want
to see how they're going to do, and you can tell pretty much when
you get in the vehicle that they're going to be okay, and then, of
course, during the liftoff, I could hear, the things she was saying
were just like we say in the sim, and so I knew she was performing
like a veteran instead of a rookie, and that was good.
Of course, the first eight and a half minutes of powered flight went
pretty well, and I don't think on that flight we had any difficulties,
but as soon as the tank came off the vehicle, as soon as the external
tank separated, we had a "jet leak" message and two "jet
off" messages, so we had three jet failures, one of them was
leaking and two of them failed to operate, and it was pretty disappointing
to me, because here for a year we've been training really hard to
go do this mission and rendezvous with Mir, and check out the procedures
and the systems and the tools that Hoot Gibson was going to need,
and we've had a "jet leak" message that indicates you don't
have enough redundancy to go do the rendezvous. Maybe the leak itself,
if you couldn't stop the leak, was going to mean that we probably
weren't going to rendezvous.
That whole first day, which is a pretty short day on orbit, you only
work for, I don't know, five or six hours and then you go to sleep.
As the day wore on, I was pretty much convinced that we were not going
to be able to rendezvous with Mir, and it was pretty disappointing.
You know, we still had other things to do, another series of objectives
and another satellite to deploy, but really, I knew the mission was
to rendezvous on Mir, and so I was pretty disappointed.
The next day and, of course, we continued the rendezvous, the burns
that get us closer and closer to Mir. The engineers on the ground
did a great job, both Russian and American, in transferring data and
really opening up the two space agencies and sharing data and communicating.
It was very difficult, and a lot of people on the ground did a lot
of tremendous work, a lot of good work to talk and discuss and share
data and to get us closer to Mir as the real vehicles were getting
closer.
By the third day, we still had not cleared the leak, it was still
leaking and you could look out the back window and you could see the
propellant going up for miles. It kind of goes in a cone-shaped pattern,
because there's no atmosphere to attenuate its motion, and it just
goes up pretty straight and it just continues, like a snowstorm for
five miles up into space.
Of course, the issue is whether or not we would contaminate Mir. You
wouldn't think it'd be too big a problem, but on the Soyuz vehicle,
which is their lifeboat from the Mir Space Station, they have optical
sensors that they use to align their platform in preparation for reentering
the earth's atmosphere, so they're going to need this thing to bring
them back to Earth, and if you contaminate the optical sensor, it
could be bad, and that was a risk that I did not want to take.
We got the sense from talking to the folks on the ground that the
engineers were getting closer and closer to saying, "Yes, you
can do the close approach," but the leak wasn't getting any slower,
to me, and I got the impression they were going to let us do it. That
night before we went to bed we were going to rendezvous the next morning
I pulled one of my crew members aside, who was Colonel Vladimir Georgievich
Titov, from Russia, who spent over he, at one time, had the world
record for the longest time off of the planet, of one year. I pulled
him aside and I said, "You know, if this leak doesn't get any
smaller, I will not bring our vehicle close to the Mir, even if they
give us a go, because I don't want to cause any problems for the cosmonauts
when they're coming back." Then we went to sleep and woke up
the next morning, and, as luck would have it, the leak slowed down.
Now, Eileen was doing a lot of work with the ground to try to isolate
the leak, and although she wasn't completely successful in isolating
the leak, it did significantly slow down the morning that we woke
up to rendezvous. We both looked out the window. Actually, the whole
crew, you know, every day we woke up, we'd look out the window and,
sure enough, it was less. So as fate would have it, now it really
looked like they were going to let us go. Now, they still hadn't given
us the official go, and we still had 1,000-foot double around the
Mir that we were going to approach. If you stay outside of 1,000 feet,
the chances are very slim that you would cause any problem, so we
knew we were at least going to 1,000 feet, but to me, that's a failure
if you don't get any closer than 1,000.
But we continued the approach and still were waiting for the go. We
had a different radio system on that flight. We were testing out a
new VHF radio that Hoot was going to use and all the crews used, to
talk directly with the Mir. You need to have, in the two vehicles,
an ability for the crew members to talk to each other, to coordinate
things separately from the air-to-ground loop, voice loop, from the
station to the ground Control Center in Moscow, and from the orbiter
to the Control Center here in Houston.
So we had a separate communication directly with Mir, and the reason
that ended up being significant is because the ground, the two Mission
Control Centers, were coordinating the approach, and they finally
had agreed that they were going to let us make the final approach,
but Houston didn't tell us right away. We heard from Mir, from the
Russian cosmonauts, that they were going to give us a go.
In fact, we were being televised, recorded and televised live to the
Mission Control Center in Houston, but they couldn't hear our audio.
All of a sudden, I saw the rest of my crew suddenly start cheering
and jumping up and down and clapping, because they knew we were going
to get the go to approach, and they hadn't told us yet, and so they
kind of stole their thunder, and I asked the crew to calm down because
I knew the Mission Control Center in Houston hadn't given us the go
yet.
So we all got kind of calm, and then later on, Story Musgrave, who
was the capcom, called up and said, "We think you know this because
of the reaction we saw, but you do have a final go to approach to
10 meters," and, of course, we simulated the euphoria again.
Wright: I suppose it was an easy part of that trip to do that again.
Wetherbee: Yes. But I was very relieved, because I knew that the two
days' worth of work, or three days' worth of work, which a lot was
being done by the ground people, that that was what enabled us to
share the data and discuss the leak and be open with each other, which
we hadn't really done too much of in the past. You know, the engineers
were still kind of wary of each other.
As we approached by the way, the previous night, I had asked you know,
for months, I was thinking, "Well, what am I going to say when
I get close?" You know, and you have to say something nice. I
was thinking about it for a while, but hadn't really decided what
I was going to say until the night before the rendezvous. I figured,
"Well, I guess we're pretty close now. I better get serious about
thinking about what to say." I decided I wanted to say it once
in English and once in Russian, since this was the first time we were
going to be close and both countries would be watching, I thought
it would be appropriate to say something in Russian. I had been studying
a little bit of Russian, but I couldn't translate it well enough,
so I asked Volodya, which is a nickname for Titov, to help me translate
it, and so I showed him. For the first time I wrote down what I wanted
to say, and I showed it to him. I didn't show anyone else on the crew.
He translated it on the kneeboard. I wonder what I did with that.
I don't remember who I gave that to. Maybe I still have it at home.
Anyway, so I practiced it a few times in my head, to make sure I could
pronounce the words correctly, and we went to sleep, and then the
next morning we woke up and were given the final go to approach. So
we did, and, of course, all of the technical things are the most important,
and the critical things that we're doing, and as we are approaching
on what we call the V-bar, which is the velocity vector of Mir, in
other words, its co-altitude, so now the two vehicles are co-altitude
relative to the center of the Earth, flying at almost exactly the
same speed, 17,500 miles an hour, and we were going 17,500 miles an
hour minus three feet per second, or whatever the number is, so we're
closing at three feet per second relative velocity. I'm not sure if
that's the exact number, but it's something like that.
As we came up, we had four different sensors that were telling us,
through a computer, what our relative position was. One of them was
a handheld laser, which is very similar to the police handheld laser
that they use to catch you when you're speeding down the road; one
was an automatic laser system in the payload bay of the orbiter, shining
at a target on Mir; one of them was the radar out on the side of the
vehicle, which at that point had started to be a little bit inaccurate,
because it was looking at different targets on Mir and walking around,
and so it was giving us different range information, and it was kind
of noisy, so it wasn't all that useful; and we had our own human eyes
that were looking out the window. We had a little, effectively, a
grease mark on the window that didn't move. It's called a COAS, Crew
Optical Alignment Sight, which is a point that you look at, that tells
you which way the orbiter is pointing.
We had those four sensors that were feeding information into a computer
to give us the relative state vector, and as we had talked many times
on the ground in preparation for this flight, this was our big goal.
Our mission objective was to see how these sensors all worked, and
as we had prepared, two of them were lying and two of them were telling
the truth. I mean, you couldn't have picked a better thing to happen
on a test flight, if this is your goal, where you don't have the pressure
of really needing to dock, like Hoot was going to have, but we still
had a lot of, maybe, self-induced pressure, and plus, you really wanted
to make sure, I've already mentioned, I was not going to get one centimeter
closer. So our job was to figure out which of the two sensors were
lying and which of the two were accurate.
I was flying with Mike Foale also, at the time, one of the crew members,
whose job it was to play maestro with his computer. He was the guy
taking all of the inputs and typing away, and it wasn't very automatic
back in those days, even though it was only three or four years ago.
He had to manually do a lot of labor on this computer, and I couldn't
have picked a better guy to do it on the crew, because he really knows
computers.
So it was pretty tense there for a while, trying to figure out what
the proper sensor was to use, and as we had simulated many times on
the ground, we chose the one that is the most reliable, the one that
is the least complicated. We chose our human eyeballs, because that's
the simplest one and you know it's going to be accurate. We disregarded
the other two, chose the two that were agreeing, and then Mike later
figured out what was wrong with the other two and was able to clean
them up and make them more accurate. So as we approached, we finally
had a good feeling about where we were.
There's another technical issue with the Shuttle. If you're on the
V-bar, co-altitude, because of the orientation of the attitude control
jets on the Shuttle, it's always causing you to get closer to the
target. If you do nothing, you will eventually get closer and closer
and impact, and, in fact, these were the two biggest vehicles that
we'd ever rendezvoused in space before. Mike Foale, one time in a
meeting when he was bored, on the ground, figured out that with the
mass of the two vehicles, he figured out the gravitational attraction
between the two, and if we were co-speed and did nothing, we would
hit within three hours because of the gravity that was sucking us
in.
Now, don't get me wrong, that's a very small effect when you're talking
about the drag effect on the orbiter and the attitude controls jets,
etc. But, nevertheless, the vehicles always want to close on each
other, and we had to physically make inputs to the flight control
system to keep the vehicles separate.
We were only supposed to stay there for ten minutes at the closest
point of approach, so we checked out the handling quality of the vehicle
and the systems and everything was working pretty well, and we came
in to right about our exact distance of a little bit greater than
33 feet. The closest point of approach between structure was 33 feet.
The number that was reported in the press was 37 feet, because that
was the distance between the laser system and the target on Mir. You
had to triangulate, and that's the longer hypotenuse of the triangle.
Not that that matters, it was just interesting to see that when we
came back it was reported, and still is reported these days, as 37
feet, but it really was 33 feet and not one centimeter closer. We
did not get a single inch closer to Mir.
Then we backed away, because now I knew I wanted to give this little
speech, and it was going to take my attention away from the distance
for a couple minutes, a minute or two, and I didn't want to close
in there, so I backed it away four or five feet, and stopped it and
got all ready to give this little speech. By this time, there's no
cameras on us, because I think we just didn't have the radar coverage
or something. Mir was blocking or something. So I knew no one was
going to be watching me, it was just an audio message, so I was able
to cheat and read, just simply read the thing from my cue card, first
in English and then in Russian.
As I got ready to read, you know, and I kept asking the crew, "Are
they ready? Are they ready?" and the crew is doing what they
do best, which is watching the technical side of things, and they
don't care about the political speech I'm going to make. I kept saying,
"Are they ready?" and they kept looking at me like, "What
is he asking us this for?" and I finally said, "All right.
Here I go. I'm going to start giving the speech now."
I keyed the mike and I started talking and just then the capcom, Story
Musgrave, started saying something to us. Because of the two-second
delay, he didn't realize that I was giving the speech. But I just
kept it keyed and kept talking, and then he quickly figured out that
I was giving the speech and so he got quiet. I read it first in English,
and I was about halfway through the Russian when I hear, from the
back, Mike Foale saying, "Back up! Back up!" Because we
were starting to get close again and we were approaching the limit.
We didn't exceed it, but as I was reading this speech in fact, I can't
even remember. We'll have to ask him. He may have come around and
made one input. I don't remember. Or I keyed it and held the book
in one hand and made a couple of inputs while giving the speech.
A couple of things I always think about giving that speech. The first
is, you know, approaching the vehicle, you're so focused on doing
the technical, the test pilot things, evaluating the systems and the
handling qualities, but you are just blown away by the sight that
you're seeing of that huge, giant Space Station out the window. Ever
since I was ten years old and wanted to be an astronaut, I've been
watching these science fiction movies of these spaceships that come
up next to a big, giant space station, and all of those thoughts came
back to me, you know. So you're trying to get that stuff out of your
mind because you have a job to do, a technical job to do, but I kept
thinking how beautiful the sight looked, how exciting it was to have
two countries, and you're helping to bring them closer together, and
all that stuff, and yet you're trying to keep that out of your mind,
but you can't because it's so awesome-looking, the view out the window.
Mir looked so brilliant and white and bright, when you're not looking
through the attenuating effects of the atmosphere. Really amazing.
But the other thought I always think about is, so then when you give
a speech, you know, you might think it would be a pretty important
historic moment, but the only thing I was thinking about was making
sure I pronounced the Russian correctly, and the only thing my crew
was thinking about was, "Don't let them get any closer,"
so it completely takes away any of the honor of doing it, and the
magnitude of the situation is just gone because you cannot screw up
up there, and that's all you're really thinking about. But I got done
with the speech, and we eventually separated and I said goodbye to
the Russians.
The other thing that was amazing about the approach was that I had
not met the crew members, and now you're I mean, 30 feet is pretty
close. It's here to the window over there. So you can see these people
through the window. I mean, very clearly. Elena Kondakova held up
the little doll cosmonaut, which was pretty neat, and Titov, her country
mate, is waving it from our side of the vehicle. And Sasha Viktorenko,
the commander, I mean, you could see these people, their eyes, and
Dr. Polyakov, who now has the record, was the other crew member.
I forgot to mention, when we were down on the ground, discussing whether
or not we wanted to get close this was back in the days when we were
arguing about how close to get Dr. Polyakov was on board at that time,
he was up there, and I think maybe even the other crew members were
there. When we were talking to them, they said, "Why do you want
to get this close? This is very difficult for us. Psychologically,
this is very hard for us." And I can understand their point.
They are not in control of the situation, and some kid's coming up
with a 100-ton vehicle, doing nothing more than adding risk, and they
get no benefit from it. They were saying, "Why do you want to
do this?"
But as we got closer to launch, Titov, one day, when we were down
at the Cape, says and he had a great idea he says, "Why don't
we talk to the crew?" and I said, "Well, how are you going
to do that?" And he says, "I know the phone number."
He calls back from a regular office telephone, and the first time
we tried it, we failed, we couldn't get through, couldn't get patched
through, but the second time he tried, we were sitting around in an
office down in Florida, getting ready to launch, talking to the crew
members, flying overhead. So we were able to develop a little bit
of a friendship, even though it was by telephone and you couldn't
see them.
So then when we saw them in person, across 33 feet of cold, dark void
of space, waving to them, it was like we were crewmates, even though
we weren't on the same vehicle, so it really was a good feeling.
Wright: Did the ten minutes seem to pass quickly?
Wetherbee: Yes. The ten minutes went by very quickly, because you're
thinking all these thoughts, and trying to do the technical side of
it. It was very emotional for them. You ought to talk to them, too,
because they don't see many human beings in their job, and once in
a while, somebody comes up, and we happened to come up and wave to
them, and it's pretty moving for them.
These are the kind of things that we learned from the Russians, the
human side of space flight, the long-duration flights we're not used
to, and the human side of it, the emotional feeling side of it, they
are teaching us. In fact, Titov one day said to me, "I notice
that the Russians talk very normally on the radio." Americans
tend to be like fighter pilots. We use a military jargon, a lingo
that is very quick and terse, and you use acronyms and you convey
a lot of thoughts into a small sentence, and it's a lot of radio silence,
and you're doing things and working. Titov said to me, "Jim,
one day you Americans will learn, it is better to talk." And
they just talk about the weather and how are things down on the planet,
and they just go on and on and on. Sure enough, we are learning those
kinds of things. Humans need to talk to each other and not just be
test pilots all the time. So that was pretty interesting.
We flew the mission. A couple days later, we had one more opportunity
to talk to the crew of Mir, and so they scheduled a fifteen-minute
pass for us to talk to them, and so I started. We had an interpreter
on the ground, who was helping us converse. Sasha Viktorenko, the
commander, in this fifteen-minute pass that we had, forty minutes
later, after starting and talking, he was showing no signs of stopping.
He was just talking the whole time. It's human contact. It's emotional,
you know. They like being with someone or talking to someone, and
I had a lot of work to do. You know, these missions we plan, everything's
timelined and choreographed to the last second, and I finally had
to tell him, "Hey, I'm really sorry, but I've got to go back
to work," and so I finally terminated the conversation.
We came back down and landed, and then I started hearing all these
other stories from folks, like Mr. [Daniel S.] Goldin, who was in
a budget meeting at the time that we approached, and he stopped the
meeting and they pulled the curtains back in this conference room
and they displayed on the screen the images of the Shuttle and the
Mir approaching. He said that moved him so much that he couldn't continue
the budget meeting after we separated. He just couldn't go back to
boring, mundane things like the budget. And all kinds of stories like
that.
A lot of Americans, I think, didn't realize that the Russians even
had a space station up there at the time, and it had been operating
and permanently inhabited for like nine years, and we didn't even
know about it in America. So it was good to let people know that the
Russians have a space program, I think.
As I think about the flight, probably the biggest thing about that
flight was the fact that we got people talking to each other, the
engineers on the ground discussing the leak, opening up their books
and sharing data with each other did a lot to help STS-71, the first
docking mission, because then they all were friends and it went along
more smoothly.
You could've done the docking mission, Hoot could've gone up there
and docked and had no trouble if we had never even flown STS-63, but
the people on the ground were a lot closer together, and so from that
point of view, it was worth flying the mission, I think. It actually
was fortuitous that we had the leak, because it forced people to communicate
and talk with each other, and it started the however many, nine docking
flights after that went more smoothly because we had that initial
communication.
The other thing I think about, about the flight, was when Hoot was
getting ready to launch down at the Cape, I went down and gave the
briefing to the guests, the VIP guests who were down there, and I
looked out into the audience, and I saw, for the first time on the
planet, Elena Kondakova, one of the crewmates. I was introducing the
crew of STS-71, who was going to launch, and I mentioned a few things
about our flight and how we had met these cosmonauts for the first
time, up in outer space, and if it was okay with her, I was going
to meet Elena Kondakova for the first time on the planet as soon as
I'm done talking here. So that was a pretty interesting experience.
Well, I got done and they, of course, had a bunch of cameras there,
and so they watched us as she came up to meet me for the first time
on the planet, which I'll always remember, meeting her for the second
time, but the first time on the planet. So that was pretty interesting.
Wright: On your next mission, you actually got to go across and shake
the hands of the folks on Mir.
Wetherbee: Right. So, STS-86, I was fortunate enough to be selected
to fly, and here I'd watched a bunch of my friends you know, I came
back from the first mission and I told Hoot, "It's easy, don't
worry. It's easy." And he didn't listen to me, you know, because
you haven't done it and you're really worried about it, and he did
a great job, as did everyone else. And then it came my turn to get
ready to dock, and I'm thinking, "Man, this is going to be hard.
I'm not going to be able to do it." And it's just something you
just can't listen to anybody who says it's easy; you're always going
to worry about it.
We flew let's see, I'm trying to remember the crew members. I had
another rookie, Mike [Michael J.] Bloomfield, who did a great job
as a pilot. I flew again with Vladimir Titov. Our job on the second
flight was to go rescue Mike Foale, who now was a crew member on Mir,
and he was up there for a couple months and had some problems, as
you know. He was on board when they had the collision, and there had
been the fire when Jerry [J.M.] Linenger was on board several months
earlier.
So as we got closer to dock on STS-86, there began to be a lot of
interest in the media about whether or not we were doing the right
thing, whether or not we should well, we certainly should bring Mike
Foale home, but should we really leave Dave Wolf up there on Mir.
There was a lot of congressional interest. A lot of people were worried
about it, thinking we were doing the wrong thing. People were saying,
"No, you shouldn't leave Dave Wolf up there."
So in the weeks leading up to the flight, normally and I've flown
four times now normally, you think about the risk really only a few
times. One of them is when you first get selected as an astronaut,
but the euphoria far overshadows the risk, so you don't really think
about it too much then. The first time you're assigned to a mission,
you think about it a little bit, but that passes because you have
so much work to do. There may be one or two other isolated instances,
like the first time you see the hardware, you may worry a little bit
about it.
But typically, you worry about the risk in my case, anyway, I worry
about it the night before the launch. When you go to sleep, and you
have to be able to deal with it. If you can't deal with it, there's
no way out. It's too late to say, "I quit," but you're not
going to be able to operate effectively unless you can figure out
a way to deal with it, and I've chosen a way to do that. I remind
myself that this is the only job I've ever wanted to do, and so it
makes it easier to deal with the risk, and if anything happens, I'm
going to try my best to make the mission a success, and save the vehicle
and the crew, but if it doesn't work, this is the only job I've ever
wanted to have and so I can live or die with that thought. So then
you go to sleep.
On this mission, we were somewhat forced to think about it a couple
of weeks before launch, and repeatedly we were asked, over and over
again, "Do you think this is too risky? Should we launch? Should
we not launch?" And so it was more of a longer-term thing, you
really had to think about the risk. And a lot of people called me.
Mr. [Daniel] Goldin, I thought, did a tremendous job. He's the administrator
and the man with the responsibility to say yes or no, launch or not.
The responsibility is all his, and he can't delegate that responsibility,
he can't share it with anyone, it's all his. That's a pretty heavy
decision to have resting on your shoulders. And so as we got ready
to launch, I thought he handled it pretty well. He had Congress on
one side and a lot of other detractors who said, "No, you shouldn't
launch," and he's thinking about the benefits and, yes, we should
launch.
He didn't make the decision until the night before. Of course, he
was in a lot of discussions with Mr. [George] Abbey, my current boss
here, who has the operational responsibility for carrying out the
policies that Mr. Goldin determines, and so Mr. Abbey also has a lot
of responsibility on his shoulders, and they talked a lot.
Mr. Goldin called us and asked us. He called Dave Wolf and asked,
"Are you ready to go? Tell me honestly," and said all of
the right things that you want to hear a boss or an administrator
say, to allow you to say, "Yes, I do have a concern," if
you have any. We didn't have any, and we wanted to launch, and he
made the decision the night before, I guess, to launch. So we all
appreciate the fact that he made that decision.
Let me back up. A week before launch, you know, we start our quarantine
period here, and then we go down to the Cape. About three days before
liftoff, we were still here in Houston, getting ready to go to the
Cape, and it's about two hours before getting in the airplane to go
down there, when they called and said I think it was a Monday "Mir
has just lost attitude control," and this was the third Monday
in a row that they have lost the ability to control their attitude,
so they're in free drift, which means if that happens during the rendezvous,
you cannot rendezvous and dock with them.
So instead of going to the Cape right away, we stopped off at the
simulator to figure out how are we going to rendezvous on a space
station that doesn't have attitude control. And as we do most things
here in NASA, in America, you plan everything out as well as you can,
you think about all the contingencies and you work at it and you simulate
it until you're tired of simulating, until you perfect the technique.
And here it is two hours before we're going to the Cape, three days
before we're lifting off, and suddenly we have a whole entire new
thing that we're going to do, to figure out how to rendezvous on a
station that's rotating.
On the one hand, I didn't think they were going to let us do anything.
They were just going to say, "Forget about it, don't worry, if
it happens, you'll land and won't dock and the mission's a failure,"
but to the managers’ credit, they allowed us to go into the
simulator and work on these procedures for, what do we do if the thing's
rotating. We worked at that and did five approaches. The first one
we blew, didn't make it. The next four, we did, after we refined the
technique.
So I was pretty confident that we could do it, but we still hadn't
quite so then we got into the Cape and we get there, and I immediately
get a phone call this is three or four hours later and they called
up and said, "We really weren't spinning it fast enough,"
so now for the next two or three days before liftoff I'm down there
at the Cape, thinking to myself, "How am I going to rendezvous
and dock if it's spinning a little bit faster than it was in the sim?"
And without even doing any simulations, I was thinking, "Well,
how am I going to do it? How am I going to do it?"
Well, I decided, through Titov, that we would call Anatoly [Y.] Solovyev,
who's now up on orbit he's the commander on the Mir to talk to him
and find out what kind of data can you give us during that situation
if you lose attitude control. We had already practiced that technique
of talking to them on my first flight, so I was happy that we had
that experience. So we called him up and said, "What are we going
to do?" He said, "I can give you I'll make a picture, drawing
you out the attitude from the Soyuz." With that knowledge, we
could get a simple spreadsheet computer program to type in, that would
tell us what do we type in the orbiter to match the rates of the spinning
Mir and then dock.
Once we had figured that out, I was able to forget about that whole
problem and go to sleep the night before launch, without worrying
about that risk anymore, and then if it happened, I knew we had something
in our hip pocket that we could use, a technique that would work.
And so we launched and, of course, didn't have any problems. But it
was one more thing in the work-up for STS-86 that made it interesting,
because so many people were talking about the fire, the collision,
and now the attitude control problem that made it interesting, and
we pretended it was like a rescue mission.
It really wasn't. Mike wasn't in any danger, and it really wasn't
a rescue mission, but it was fun to think about it that way.
So we launched. Mike has some great stories that he could tell you
about, the feelings that you have when you're a crew member who's
been away from the planet for four months, and you hear that your
rescue vehicle, or your transportation vehicle, has now launched and
is safely in orbit. Unfortunately, they only told him that we launched.
They didn't tell him that we were safely in orbit, so he still had
to wait several more hours before they finally said, "Yes, they're
in the proper orbit that they can come and get you." But he still
was thinking you know, you have to prepare yourself mentally for this,
and you don't want to get too psyched too early and then be deeply
disappointed, so he wasn't thinking we ever were going to make it,
something would happen and we wouldn't come and get him, and he's
just preparing himself for the worst.
But then on rendezvous day, when we come up oh, the other thing I
forgot to mention. The other reason the Russians were very worried
about the orbiter coming up and docking was because, just like the
Apollo, the Soyuz vehicle that they have all their experience with,
and the Progress vehicle, has a tremendously high thrust-to-weight,
so as it's rendezvousing, it's moving around a lot. They fire a couple
of jets as they're approaching, they're really moving, and it's pretty
scary-looking if you see it. Their system is done automatically, and
it finally fades it out, and it slams into a docking.
Well, you can imagine, that would be pretty difficult if you had a
100-ton vehicle that was doing the same thing. Well, what people overlooked
was, a 100-ton vehicle has a very low thrust-to-weight. It's like
a big ocean liner coming in, and things are done more slowly. It's
a very good system designed by really good engineers, and the handling
qualities are perfect in this thing, when you're talking about that
kind of a docking.
And so on 63, I think a lot of people were surprised at how stable
the vehicle looks, how motionless it looks as it's coming in, and
it's very controllable. So that was another thing that gave the Russians
a lot of confidence on 63, that the rest of these dockings were going
to be okay, not like a Soyuz or an Apollo.
So anyway, now our vehicle is coming up very slowly and stately, and
Mike Foale is watching us get closer, so for the first time he's thinking,
"Well, this is really it. They're really coming to save me, or
get me, and this is pretty good." And so then you dock. We had
talked with Anatoly Solovyev on the radio. We had a new attitude control
computer for him and his spaceship, and we were supposed to give it
to them on the second day of docked operations, and Anatoly told us,
"No, I don't want to wait till the second day. I want you to
give me that computer as soon as we have the handshake ceremony."
So I decided to go him one better; I decided to give it to him during
the handshake ceremony. Titov went down and drew a happy face on the
outside of this box, and we opened up the hatch, and I shook hands
with him with one hand, and with the other hand, gave him his attitude
control computer, and he was so happy to receive that. Then each of
the other crew members gave him this big, huge bucket of water that
we bring up for them to use.
The only other part of that flight that will always stand out in my
mind was the night so you dock and you go in and you have the initial
press event, where you have the ceremony and the press conference,
with all the crew members up on board, and it's staged, and you say
things that you've thought about. They're a little bit of fun, in
a weird sort of way.
But the best time I had was later on that night, there are no cameras
now, so no one on the Earth saw this going on. We went across and
had a meal with them, a Russian dinner with them, and they were playing
a tape, an audio tape, on their great stereo system that they have
up there, and it was a song that I'll never forget, and they were
playing on the video system a replay of us rendezvousing with them,
so I could see our own vehicle coming up to rendezvous, listening
to this great music. It was just a weird sensation that I'll never
forget, because here I am now, on the Space Station, after having
just rendezvoused, so all these memories of when I was a kid came
back. It really was neat. Something that I'll never forget.
We transferred several tons worth of equipment and water and supplies,
and one person to the Mir, Dr. David Wolf, and then we brought Dr.
Mike Foale back, and to watch them you know, Mike is very happy and
he's trying to contain his glee and his excitement about leaving,
because you don't want to offend or upset David Wolf, who's going
to be there for a long time now, just to see his face, it's pretty
difficult to say goodbye to him. It's difficult, more difficult for
him to say goodbye to us, and to watch the hatch close, with him on
the other side, but he did a great job for the four months that he
was up there.
I'll just tell you one more story, and it's Dave Wolf's quote, but
I just loved what he said, and it kind of illustrated all of the thoughts
that we had leading up to the mission, talking about the risk and
everyone asking us about risk, and should we leave him up there. He
did a great job of dealing with the risk, both pre-flight and during
the flight. But each night he would talk to the ground controllers,
the people who were arranging his next day's events and working the
experiments with him, coordinating things on the ground. He would
close each of his nightly telecoms with them, you know, he'd talk
to them for fifteen or twenty minutes, and at the end of every telecom,
while we were docked for the six days that we were docked, he'd end
his transmission by telling them on the ground, he'd say, "Well,
be careful down there on the ground." No, wait. I messed it up.
He said, "Now, be careful down there. You're awfully close to
the ground. You don't want to get hurt." It was a great way to
think about risk. He's up there, floating around in what astronauts
tend to think of as a relatively risk-free environment, although there
are some risks, but he's telling the people on the ground, "Don't
worry about me. You take care of yourselves, and I'll be okay up here."
I just thought it was great the way he would say that. "Be careful
down there on the Earth. You're awfully close to the ground. You don't
want to get hurt." So I've used that quote many, many times.
I guess that's all I can think about STS-86. I was honored to have
been selected, and it was a great mission that worked, mostly because
of the people on both sides of the ocean, down on the ground, who
make it work and that's the case with all these missions. It's the
people on the ground who make them work, and then we get to have the
fun.
Wright: Of course, on 86, you had an additional international member,
is that correct? Because you had Titov and then you had a French crew
member?
Wetherbee: Jean-Loup Chretien, who was the first person outside Russia
or America to perform a space walk. He's a French cosmonaut. In fact,
he's the chief of the Spationaut Office in France. They call them
spacionauts. He flew with us. He had been on Mir before and had flown
with Titov before, nine years earlier, and so here he was on Mir for
the second time. And so they had some reminiscing to do when they
got up on Mir. Jean-Loup did a great job with us.
Titov, by the way, showed us the bunkroom that he spent a year off
the planet and showed where he signed the wall with his signature,
and you can still see it, you know, millions of, billions, maybe,
of miles later, here's his name up there, so it was pretty interesting
being on board the Mir with cosmonauts who had flown it when it first
was up in space, so it was pretty interesting.
Wright: I really appreciate your time. What time we had scheduled
with you is up, and we don't want to take any more unless you have
more to give us, because it's certainly up to you and your schedule.
Wetherbee: Probably not.
Wright: All right. We thank you and wish you the best of luck. Your
job may be finished with Shuttle-Mir, but I am sure that they are
full every day doing more for whatever projects you're assigned to
next.
Wetherbee: And I'd still love to get back there some day, because
I'm not finished with the training part and the flying part. Hopefully,
I'll get to go fly again. It's an awful lot of fun.
Wright: We wish you the best of luck. Hope you do, too.
Wetherbee: Thank you.
