Failure Is Not an Option Read online

  The Space Task Group’s launch team was permanently stationed at the Cape to support the test and checkout of the rocket and capsule. The flight team of which I was now a member, the astronauts, engineers, and program office operated from Langley Air Force Base and traveled to the Cape for each mission. I had been on the job in Virginia only two weeks, hardly long enough to figure out the pecking order, when Kraft walked up to my desk and said, “Everyone else is tied up. You’re all I’ve got. We’re coming up on our first Redstone launch. I’d like you to go down to the Cape, get with the test conductors and write a countdown. Then write some mission rules. When you finish give me a call and we’ll come down and start training.”

  The shock on my face must have registered as Kraft continued: “I’ll tell Paul Johnson to meet you at Mercury Control to give you a hand.” When Kraft talked, his eyes never left mine. I was given this assignment mainly because I was available. In this period of intensive development, jobs were open all over the place; NASA was forming organizations for mission planning, recovery operations, astronaut training, launch operations, and Mercury Control. Every new hire with the requisite technical and scientific credentials was put into a job slot the minute he came on board.

  Kraft was one of the original thirty-six members of the Space Task Group, most of whom stepped forward to do a job that had never been done. He recognized that someone had to be in charge of the ground effort and he volunteered to lead that effort. A graduate of Virginia Polytechnic Institute, Chris had worked at Langley in the aircraft stability and control laboratory. My senior by nine years, he did not immediately impress me as a leader, the way some of my early mentors had. Kraft led a step at a time, and each Mercury mission added a new dimension to his presence and style.

  My days as an observer were over, my chance to get up to speed ended. This was the first indication that my job slot would be in Mercury Control. Some people in Mercury Control had technical experience working on the tracking stations or at the Cape on the Vanguard, Explorer, and Pioneer missions. Others, like me, came from aircraft flight testing or were engineers from the pilotless aircraft research program at Langley. From my work, most recently at Holloman AFB in New Mexico, I knew about flying, systems, procedures, and checklists. I could figure out what a countdown should contain. Mission rules were different. There had never before been such a mission in U.S. history—I would just have to give it a shot. Since there were no books written on the actual methodology of space flight, we had to write them as we went along.

  There was a relatively small group working down at Mercury Control, forty to fifty people. Some of them had grown up launching the early U.S. rockets derived from the German V-2 of the Second World War. Now, in a few months, we would attempt to send the first American into space. It was a scary thought, but not for anyone who had been around test pilots.

  I had flown supersonic F-100s, which needed at least a mile to get off the runway on a good day. When you took off at 230 miles per hour, if the engine crapped out or you lost the afterburner, it could quickly become a bad day. But when you punched through the sound barrier it was a jolt of pure adrenaline. The SuperSabre looked like it was more than capable of carrying out its air superiority mission. But you had better be ready when you strapped yourself in. No matter how skilled you were in handling it, you were never sure when the elements or the aircraft, in a perverse way, would decide to test you. Every time I climbed aboard I could feel the thrill of tension and anticipation.

  At Holloman AFB, where I had worked as a flight test engineer, we had been putting people into scary situations for years. It was not unusual for a guy to climb to an altitude of 100,000 feet in a balloon and then bail out in a parachute, falling 90,000 feet before his parachute opened. This was the environment of risk and these were the kinds of people who had been picked as the Mercury Seven astronauts.

  Looking back, I can see now how minimal, even primitive, our facilities were at the time, both in the control center and in the blockhouse—a massively reinforced structure placed as close as prudently possible to the launch pad where the guys who were responsible for the actual functioning of the rocket manned their posts. We tended to talk about “the Germans in the blockhouse” largely because Wernher von Braun and his cohorts, who had worked on the rocket programs, came to the United States after Germany’s defeat in World War II. They were originally stationed near El Paso, Texas, and tested captured V-2 rockets for the military at the White Sands, New Mexico, test range. Later they were moved to permanent facilities at Huntsville, Alabama, and worked for the Army Redstone Arsenal. Most of the Germans became American citizens, adopting Huntsville as their home. In 1960 rocket development at the Redstone Arsenal was transferred to the newly formed Marshall Space Flight Center (MSFC), and von Braun, along with nearly 100 other German scientists and technicians, began work on a powerful series of rockets called Saturn I.

  At this point in the space program, our communications network was actually run out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. It had been named after Dr. Robert Goddard, the American pioneer in rocketry, who had developed rocket engine and guidance technology in the 1930s equal, if not superior in some respects, to what von Braun and his colleagues were working on as late as 1945. Goddard, one of my boyhood heroes, had had the backing of Charles Lindbergh, which enabled him to test his rockets in New Mexico, not far from the site where von Braun and his Germans would fire the first captured V-2 rockets in the late 1940s and test those that evolved from V-2 technology in the years that followed.

  The German scientists and technicians would come back to the Cape occasionally for selected launches (particularly high-profile manned missions), but they had their hands full at Marshall developing a new generation of rockets. By the time NASA launch operations were forming up, American engineers were well acquainted with rockets, building on the experience of the Germans, as were the contractors producing the Redstone and Atlas missiles. While the new generation of American scientists and engineers was now doing the job, the first boosters in the manned spaceflight effort were barely adequate, as events would demonstrate. In many ways this technology was as “out on a limb” as Charles Lindbergh’s Ryan monoplane. He didn’t have any manuals either, and his facilities were primitive. Roosevelt Field in 1927 and Canaveral in 1960 had a few things in common. The massive Cape facility that would grow up in the next decade and soon become the Kennedy Space Center (which would include the largest enclosed space in the world, the vertical assembly building) was beyond our wildest dreams at the time.

  In 1960 the Cape looked like an oil field, with towering structures, dirt, and asphalt roads newly carved out of the palmetto scrub. The alligators were reluctantly surrendering to the onslaught of newly arrived civilization. If you didn’t have a good sense of direction you were in trouble. There were few directional signs and once you got off the road visibility narrowed. At night you could easily imagine the gators and snakes taking their revenge on any intruder foolish enough to be wandering around on foot, lost in the boondocks.

  The man in space program was simple in concept, difficult in execution. Every mission was a first, a new chapter in the book. Many, if not most, of the components in both rockets and capsules had to be invented and handmade as we went along, adapting what we could from existing aviation and rocket engine technology. Before putting a man on top of a rocket, we would first fly one or two tests with a “mechanical man,” a box full of electronics weighing about as much as an astronaut to simulate the conditions that would be present when an astronaut was on board the capsule. The capsule would send back some prerecorded messages to test our communications. Then we graduated to spider monkeys—and then to chimpanzees, working our way up the evolutionary ladder, so to speak. The missions were initially to be twenty-minute lob shots, using the Army’s Redstone rocket; then we would go into orbit with the Air Force’s first-generation Atlas intercontinental missiles. The military boosters were barely ready for ope
rational use. Here the missile gap was indeed real—except the gap was between what the hardware was supposed to do and what it had shown it could do.

  The day after I arrived Paul Johnson and I went to the launch pad. I was shocked when I first saw the Redstone rocket. It was stark, awkward, and crude, a large black-and-white stovepipe atop a simple cradle. It had none of the obvious coiled power and distinctive personality of an airplane; it was not graceful in form, not something you could come to love and rely on. The Mercury capsule squatted atop the rocket, black in color and seemingly constructed of corrugated sheet metal. With its tall red escape tower it looked more like a buoy in a harbor than a rocket ship from a science fiction novel. Given the oil field-like setting in the wilderness and the crude appearance of the rocket, I felt more like a drilling rig roughneck than a rocket scientist when I made my way into the bar of the Holiday Inn that evening.

  Putting any reservations aside, I plunged into working with Paul on defining the joint tests of control and communications systems, as well as the Go NoGo points for telemetry display, command, and communications in Mercury Control. My next step was to synchronize the Mercury Control Center (MCC) countdown with the capsule and booster countdowns. Paul Johnson returned to Langley to deal with a set of problems in the tracking network while I completed the work down at the Cape. To this day I feel enormous gratitude to Paul for giving me a running start. This was one of the critical moments in my life when someone stepped in and pointed me in the right direction.

  I had left behind a world where airplanes were flying at roughly five miles a minute. In this new, virtually uncharted world we would be moving at five miles per second. During a mission countdown, or even a flight test, so many things would be happening so fast that you did not have any time for second thoughts or arguments. You wanted the debate behind you. So before the mission, you held meetings to decide what to do if anything went wrong.

  You wrote down on paper the outcome of these meetings and this became what you needed for a launch, your personal list of Go NoGo’s. There was no room in the process for emotion, no space for fear or doubt, no time to stop and think things over. A launch is an existential moment, much like combat. With no time to think about anything, you had to be prepared to respond to any contingency—and those contingencies had to be as fully anticipated as possible before you pushed the button. You also had to be thoroughly knowledgeable about the responsibilities of launch control and range safety. During a launch the only mission alternative to save the capsule was an abort, and we had to pick the points to act before the range safety officer (RSO) stepped in to blow up the rocket and the capsule after launch if things went to hell.

  By the end of the first week we had just finished the initial paperwork for the countdown procedures and mission rules, but had yet to run a simulated countdown. I was finally breathing easier. Johnson had taken me from Kraft’s few words on what he wanted done to a point where I finally knew what he was talking about. It was only some six days after my “rocket ride” with Gordo Cooper, but my job was starting to seem real to me. The few days of hands-on familiarity with MCC systems now tied into the concept of the MCC team. The MCC was coming together as a working reality. My newfound knowledge, while only paper thin, was as good as anyone else’s. It was now time to put it to the test. I called Kraft and said the countdown and the operational rules were ready.

  Shortly before the rest of the team that would be involved in the first launch arrived from Langley, I made a thoughtful walk-through inspection of the relatively small—in comparison to later control centers—space that contained the operating elements of Mercury Control.

  When a fighter pilot arrives at a base the first thing he does is go down to the flight line and look at the new airplane he is going to fly. You walk around it, feel the skin, climb up on the wing, and look in the cockpit, knowing that soon this airplane is going to be yours. It is a time when you feel a bit cocky, knowing that you are one of the few who will be privileged to live in this highly charged new world of high-speed flight.

  I felt the same way on my solitary walk around the Mercury control room; I felt like I was meeting an airplane. I was, at long last, feeling at home. The telemetry, communications, and display areas were like the facilities at Holloman, but there was no counterpart for the control room itself. The room was square, about sixty feet on each side, dominated by a world map in the front. The map contained a series of circles, bull’s-eyes centered on the worldwide network of tracking stations. Below each were boxes containing many different and, for the uninitiated, unintelligible symbols. A toylike spacecraft model, suspended by wires, moved across the map to trace the orbit. On each side of the map were boards, where sixteen critical measurements were plotted by sliding beads, like those on an abacus, up and down wires as the capsule circled the world. In less than four years much of this technology would be obsolete—only the concept of Mission Control would remain. The meters and console displays would eventually be replaced by television displays driven by computers, which provided the controllers virtually instantaneous access to every bit (or byte) of the spacecraft’s data. Digital systems would enable ground control of the space systems. This would make it possible for controllers on the ground to work in partnership with a spacecraft’s crew to achieve the objectives of any flight. But this was yet to come; now we had to control the missions with fragile communications, a first-generation solid-state computer, slide rules, and guts. We were in the Lindbergh stage of spaceflight.

  Given my aircraft test flight background, the control room felt vaguely familiar, with the exception of the three rows of consoles on elevated platforms. Each console was configured differently. Consoles on the top row were flat pedestals with communications boxes on top. When I first arrived at the Cape, Paul Johnson had taken me on a tour of the control room and pointed out the procedures console. I sat at the console, staring at the flat gray face and writing desk. The only instruments were a clock and an intercom panel with a rotary (!) phone at the top. This was the state-of-the-art work station that Paul and his colleagues from Western Electric had designed from scratch. It was on the left, in the middle row, and closest to the Teletype room. As I sat down at my console, two people came over and introduced themselves.

  Andy Anderson, tall and skinny with long, sandy hair, was the boss of the communications center. His hotshot Teletype operator, a short red-head with a brush cut, was simply “Eshelman.” No one called him anything else. During a launch, I reeled off a running account of key data on the sequence of events to Eshelman, who typed them out and transmitted them by landline and radio links to remote tracking stations in Bermuda, Africa, Australia, and distant islands and ships in the Atlantic and Pacific. Eshelman had the skill and grace of a concert pianist as he stood, intently bent over the Teletype keyboard, interacting in real time with the Bermuda Teletype operator, just as if they were having a conversation. The tools we used in Mercury were primitive, but the dedication of highly trained people offset the limitations of the equipment available to us in these early days and kept the very real risks under control. But at a price; this was high-sweat, high-risk activity, demanding a degree of coordination between the ground and the capsule exceeding what I had experienced even in the testing of experimental aircraft.

  During the next two years, Anderson, Eshelman, and I controlled virtually all the Teletype message traffic originating from Mercury Control at the Cape. This was the heart of the ground control system, tied to that tenuously linked chain of tracking stations and manned remote sites by a variety of communications systems. Low-speed Teletype provided the backbone, and the controllers became adept at moving messages rapidly between the tracking sites as the spacecraft passed overhead.

  The tracking network voice system used a massive manual switchboard up at Goddard; its operator plugged cables into a bewildering assortment of jacks as he performed a frenetic ballet. He carried a thick bundle of cables wrapped around his arm, darting from one part o
f the big switchboard to another, making connections manually so we could talk to tracking sites and working around bad circuits to provide alternative connections. This remarkable guy, known as “Goddard voice,” was another guardian angel.

  Since we never knew whether every link had heard the voice exchanges, as a cross-check I transcribed every major communication into a Teletype message. We didn’t have computers in Mercury Control. So the radar information from the launch, orbit, and reentry was transmitted by tracking sites around the world to the computers at Goddard for processing, and then sent down to drive the plot boards in Mercury Control. Advanced as they were at the time, and filling whole large rooms, those computers had a speed and processing capacity easily exceeded by desktop PCs today. So our margins for error were made even thinner by the limitations of these resources.

  While waiting for Kraft’s full team to arrive from Langley I explored everything from the launch pad to Hangar S, where they checked out the spacecraft prior to launch. I was welcomed everywhere by engineers and technicians who were as new to their jobs as I was. All of them were eager to discuss their work, trade ideas, and figure out how each of us fit into the total picture. I felt that I was not alone, that virtually everyone was writing their game plan as they went along. I felt an undercurrent of organization that was emerging from a leadership structure still solidifying.
