Gene Kranz
Eugene Kranz was the Director of Mission Operations at
Johnson Space Center. Kranz joined NASA in 1960, eventually
working with all of the odd-numbered Apollo missions. He
retired in 1994, and is now a sought-after lecturer.
On the importance of the Gemini program:
"Gemini's job was to develop, test, and prove the
technologies we needed to go to the moon."
Gemini's job was to develop, test, and prove the technologies
we needed to go to the moon. It was the essential stepping
stone. It was the keystone of the Apollo program. From a
standpoint of success, it was 100 percent successful. We
developed the systems technologies, we developed the
confidence in our ability to use these technologies. We
demonstrated the ability to fly for long durations, to
rendezvous two spacecraft. Probably the most difficult one was
the one associated with extra-vehicular operations (EVA).
Because we were completely, almost taken aback. We had a very
successful Gemini 4 EVA with Ed White, and then I had the
Gemini 9 EVA and we fell flat on our face. We found out we
didn't have the proper positioning aids, restraints, training,
the suit technologies. We didn't have the anti-fog compounds
to keep moisture off the faceplate. And yet, we still didn't
learn our lesson there. We went through a very difficult
Gemini 10, Gemini 11, and then we had one of these science
groups come in and say Hey, you're doing it all wrong. Go back
in and look at the fundamentals of the job. This is how you
ought to train in the concept of neutral-buoyancy training
came in, so the last block to fit into this matrix we had to
develop for Apollo was extra-vehicular operations, and we
closed that out in our final mission.
On Apollo 8:
"When they read from the book of Genesis, I cried. And
that's all there is to it."
Oh, I was fortunate. I was probably the most fortunate person
in Mission Control, because I wasn't working the mission.
Cliff Charlesworth had picked this mission up, and I was
absolutely mesmerized by what was going on. I mean, sitting
next to him in Mission Control throughout the maneuvers, and
all of a sudden you find out that—my God, the crew has
left the Earth's environment. Okay, it's now on the way to
another planet for the first time, so holy cow, this is
something. And then the thing that really came down and
grabbed me was the crew would describe the surface as they saw
it. They would describe the backside, and then they started
naming surface features for the people they thought got them
there. The gurus and the Krafts, and you know, then their
names, their portions, astronauts and the pioneers who had
died on the way to the moon. And you sit there and you say, my
God, I'm glad I'm a spectator at this thing as opposed to
having to do something, because I got so involved in what the
crew was saying. And then when they read from the book of
Genesis, I cried. And that's all there is to it. I mean, this
was, there is no question, there are a lot of times in my life
when I've been brought to tears by just the power, the
immensity, the beauty of what we were doing, and this was one
of those days.
On Mission Control:
"The controllers had come up, they had developed a set of
values that are expressed by simple words: discipline,
morale, toughness, competence, commitment, teamwork."
Well, the nature of Mission Control as it emerged from Mercury
through Gemini and into the early Apollo was really one of an
incredibly and intensely dedicated team of very young people.
My controllers at the time of the first lunar
landing—our average age was 26. I was 35. I was the old
man in this room essentially. The controllers had come up,
they had developed a set of values that are expressed by
simple words: discipline, morale, toughness, competence,
commitment, teamwork. And it was these characteristics that
built the chemistry that would keep us together both in good
times and especially in bad times. The room, the hours that we
worked were incredible. I don't think anyone ever worked
anything less than 10 to 12 hours each day. Saturday was a
normal day of work; in fact, that's the way we felt it should
be. We were given this impossible dream by President Kennedy,
and we were living it. We were doing the kinds of things that
engineers would kill for. And as part of this process, we'd go
and open up our pay—we were surprised we were getting
paid by this thing here. As long as we had enough money to
make things meet, that's all we needed. The job was our life,
and we lived this literally every day. And this room, it's a
marvelous leadership laboratory.
On Apollo 11:
"We landed somewhere with about between seven and 17
seconds of fuel remaining."
It was really amazing how this team completely had lost sight
that this was the day of the lunar landing. That we had really
gone for the moon. This was just another problem that we had
to solve. And as we got close down, the one thing that really
started getting to me—we watched the clock, and normally
we had landed on the surface of the moon about 10 minutes from
the time that we had started the engine on our way down. We
were now 10 minutes and we weren't even close to the surface.
So we knew it was going to be a horse race. Are we going to
run out of fuel? That started becoming the next critical
issue, and at the time that we got the 60-second call from my
controller, we still weren't close. And we don't have a very
precise fuel gauge. What we have here is a controller who is
eyeballing how much the crew is throttling up and throttling
down. Once we got the low-level discrete. We got pretty good
at eyeballing that thing. We had got the 60-second call, we
got the 30-second call and about the time we got the 30-second
call the crew said, hey, we're picking up some dust and we
knew then that we were close and then I knew that no matter
what I would say or do from now on, this crew is going to go
in for the landing. So we just shut up here on the ground, and
all we were doing was letting them know what their fuel status
was. We landed somewhere with about between seven and 17
seconds of fuel remaining. That's the size of uncertainty that
we had in our ability to measure fuel at that time. It was a
horse race.
