Remembering Wernher von Braun on his 100th Birthday

Today is the 100th anniversary of the birth of Wernher von Braun (March 23, 1912-June 16, 1977), one of the most famous rocketeers and advocates of spaceflight that ever lived. Accordingly, it is an appropriate time to reflect on his remarkable life and career. A longstanding “space cadet,” von Braun was an early member of the “Verein fur Raumschiffahrt” (Society for Spaceship Travel, or VfR). Although spaceflight aficionados and technicians had organized at other times and in other places, the VfR emerged soon after its founding on July 5, 1927 as a leading group that both advocated for spaceflight and worked to build rockets. Growing up in the VfR, Wernher von Braun became the quintessential and movingly eloquent advocate for the dream of spaceflight and a leading architect of its technical development.

He achieved a new stage for his efforts in 1932 when the German army hired the charismatic and politically astute Wernher von Braun, then only 20 years old, to work in its military rocket program. While he was the first VfR member to go to work for the German military, he was far from the last. Under his direction, of course, Nazi Germany developed the V-2 ballistic missile in the early 1940s.

Von Braun’s motivations for this move, with the hindsight of Hitler’s rise to power in Germany and the devastation and terror of World War II, have been questioned and criticized. Under von Braun’s technical direction, with political oversight provided by General Walter Dornberger, Germany developed the V‑2 rocket, the first true ballistic missile. The brainchild of Wernher von Braun’s rocket team operating at a secret laboratory at Peenemunde on the Baltic coast, this rocket was the immediate antecedent of many of those used in the U.S. space program. A liquid propellant missile rising 46 feet in height and weighing 27,000 pounds at launch, the V‑2, called the A-4 by the Germans involved in the project, flew at speeds in excess of 3,500 miles per hour and delivered a 2,200 pound warhead 500 miles away.

V-2

Two months before the Nazis came to power in 1933, physics student Wernher von Braun went to work on rocket weapons for the German army. Von Braun's establishment made a breakthrough to large-scale rocket engineering. It created the world's first operational ballistic missile: the V-2.

First flown in October 1942, it was employed against targets in Europe beginning in September 1944, and by the end of the war 1,155 had been fired against England and another 1,675 had been launched against Antwerp and other continental targets. The guidance system for these missiles was imperfect and many did not reach their targets, but they struck without warning and there was no defense against them. As a result the V-2s had a terror factor far beyond their capabilities.

With the V-2, on the morning of September 8, 1944, the world changed in ways that happen only rarely. After an enormous investment by Hitler’s Germany, more than a decade of research and development (R&D), the deaths of thousands of concentration camp laborers (with many more to come), and allied fears that led to an air strike on von Braun’s rocket R&D facility at Peenemünde, the V-2 changed the nature of warfare. After some false starts, at 8:40 a.m. on this date the first V-2 of the rocket campaign lifted off toward Paris. It exploded at high altitude and never reached the allied lines around Paris, an indication of the experimental nature of this complex new technology. Two hours later, however, a second rocket struck the Paris suburb of Charentonneau à Maison-Alfort, killing six people and injuring 36 others. All of them were non-combatants. This was the first ballistic missile attack in history, and it signaled a new age of warfare in which billions of dollars would be expended to strike enemies with missiles as well as to detect, deter, and defend against ballistic missiles.

Nazi Germany’s astounding success in developing a ballistic missile while the other combatants had not done so was no accident, and it was in no small measure the result of personalities involved in the research. Before 1941 the United States had led the world in rocket technology, chiefly because of the work of Robert H. Goddard. But he failed to gain the support of either other scientists or the U.S. government. On the other hand, the energetic von Braun courted his scientific colleagues and those in the German government. No similar level of salesmanship took place in any other nation. Popular and top-level support was therefore lacking, and von Braun was able to capitalize on this with its V-2 development during the war.

Advocates of spaceflight have tended to lionize individuals associated with this effort, not so much because of the V-2’s rather negative history as a potential weapon of mass destruction but because of what it meant for space exploration in the 1950s and 1960s. This has prompted a celebration of the von Braun’s team’s role in the development of American rocketry and space exploration even as it minimized the wartime cooperation of von Braun and his “rocket team” with the Nazi regime in Germany. Both have been distortions of the historical record. Even today, few Americans realize that von Braun had been a member of the Nazi party and an officer in the SS and that the V-2 was constructed using forced labor from concentration camps who were worked to death. The result has been both a whitewashing of the less savory aspects of the careers of the German rocketeers and an overemphasis on their influence in American rocketry.

Explorer I, the first U.S. earth satellite was launched by a Jupiter-C with U.S. earth - IGY scientific experiments of Dr. James A. Van Allen, which discovered the radiation belt around the earth.

Wernher von Braun was a stunningly successful advocate for space exploration and has appropriately been celebrated for those efforts. But because he was also willing to build a ballistic missile for Hitler’s Germany, with all of connotations that implied in the devastation and terror of World War II, many of his ideals have also been appropriately questioned. For some he was a visionary who foresaw the potential of human spaceflight, but for others he was little more than an arms merchant who developed brutal weapons of mass destruction. In reality, he seems to have been something of both. In the 1960s, as the United States was involved in a race with Soviet Union to see who could land a human on the Moon first, political humorist Tom Lehrer wrote a song about von Braun‘s pragmatic approach to serving whoever would let him build rockets regardless of their purpose. “Don’t say that he’s hypocritical, say rather that he’s apolitical,” Lehrer wrote. “‘Once the rockets are up, who cares where they come down? That’s not my department,’ says Wernher von Braun.” Lehrer’s biting satire captured well the von Braun’s divided legacy.

Trajectories of Space Flight (Part Two)

In a previous blog post, I discussed the influence that Wernher von Braun had on the vision of the way that human space travel would progress, from brief flights into space to long duration missions to Mars.  To continue that discussion:

Wernher von Braun envisioned the space station to be something quite different from the International Space Station that is now in orbit: he imagined a wheel-shaped vessel that rotated to provide artificial gravity for its crew. It would serve as a refueling station, assembly station, and general “base camp” for deep space missions. Von Braun envisioned its crew playing a critical military role, conducting reconnaissance and even delivering nuclear weapons to targets below. Events proceeded along a different trajectory. In the heat of the Apollo program, NASA found that it could achieve a landing on the Moon faster and with fewer (only one) rocket launches, if the rendezvous and docking took place in orbit around the Moon, not Earth. That undercut the reason for having a space station as a base camp. Current plans for deep space exploration call for an Earth orbit docking, in which a small, crewed vehicle will dock with a heavier, uncrewed vehicle that will contain hardware for a deep space voyage. But this configuration involves little or no construction in Earth orbit, and would not require a human crew to assemble a Moon or Mars ship.

Likewise, as the U.S. military developed intercontinental ballistic missiles, reconnaissance satellites, signals-intelligence satellites, and other unmanned systems, the notion of a space station as a military base faded as well. Indeed, although historians have emphasized the connection between science fiction and the evolution of the U.S. space programs, the lack of Buck Rogers/Star Wars shoot-outs in space, so common in science fiction, is conspicuous by its absence in reality. This is a glaring example of a disconnect between depictions of space travel in science fiction and what has really happened. The closest the United States ever came to that was the highly-classified Manned Orbiting Laboratory (MOL) program, in which an Air Force crew would occupy a modest station, based on Gemini hardware, in low Earth orbit. As automated reconnaissance and other military satellites improved through the 1960s, MOL was cancelled in 1969, before any hardware had been orbited.

The concept of rotating the station to achieve artificial gravity was never adopted, either, although people who spend extended periods of time in space do suffer from the effects of weightlessness. A rotating station adds mechanical complexity, weight, and cost. One reason for having a space station is to enjoy a micro-gravity environment for research; thus a rotating station would also need a non-rotating component, further adding weight and complicating the design. As astronauts gained experience in longer duration flights in the mid-1960s, NASA concluded that this requirement could be relaxed, if compensated by training, conditioning, and other procedures for those living for an extended period in weightlessness.

Over and above these modifications to the von Braun paradigm is the notion that one need not send humans to Mars at all, but rather explore the red planet with robots. This was never part of von Braun’s vision, yet robotic exploration of Mars and the outer Solar System has been part of NASA’s accomplishments in the past two decades. Those accomplishments are due in part to what is commonly known as “Moore’s Law,” the overall exponential increase in computing power since 1960. But one must be more precise about the nature of advances in computing as they apply to the substitution of robots for humans in space. We see this issue in current debates over NASA’s plan for future human-tended missions. In spite of the accomplishments of robotic craft, NASA leadership feels that these robots are no substitute for human beings. With all of the criticism of NASA in recent years, public support for sending humans into space remains high. To resolve this issue in favor of the robots, computers need not just get more and more capable—they are already doing that nicely—they also must attain a high level of artificial intelligence (AI), which will endow them with a consciousness that matches the consciousness of human astronauts. Human beings will long to personally travel through deep  space, regardless of the obstacles. That may not be practical, but perhaps one can provide a fully equivalent experience by downloading one’s consciousness onto a computer. Is that possible? Given the pace of computer technology, we ought to know in a few years.  If Moore’s Law continues to hold up, we will have computers with a density equivalent to that of the human brain by about 2030. Even if such “virtual travelers” prove impractical, robotic explorations will continue. The coming decades ought to be among the most exciting in space exploration.

Trajectories of Space Flight

The rich collections of space artifacts at the National Air and Space Museum provide a remarkable resource for scholars who wish to understand the special place that deep space exploration has held in the imagination of not just Americans but people around the world.  They show the complex interplay between the dreams of spaceflight, the limits to our knowledge of engineering and science, and the clever ways human beings have achieved some—but not all—of those dreams while keeping at least one foot grounded in reality. Here are some examples of space artifacts currently on display, and what they tell us about our future in space.

V-2 Missile

The German V-2 rocket was the world's first large-scale liquid-propellant rocket vehicle, the first long-range ballistic missile, and the ancestor of today's large rockets and launch vehicles.

Space historians have given a central place to the writings and work of Wernher von Braun, one of the developers of the German V-2 ballistic missile during World War II, who came to the United States after the War and played a significant role in the development of the Saturn rockets, which took human beings to the Moon between 1968 and 1972. Von Braun was both an engineer and a tireless popularizer and promoter of space travel, writing a science fiction novel, magazine articles, and collaborating with Walt Disney on a television series about humanity’s future in space. In these efforts, he sketched a roadmap that became known as the “von Braun Paradigm”—a set of incremental steps that he argued ought to be taken to gain access to the heavens. In its simplest form, he argued for:

  1. the development of a winged, reusable, piloted launch vehicle
  2. which would shuttle crew, supplies, and fuel to and from a space station in Earth orbit
  3. from which would depart crewed missions to the Moon
  4. followed by a manned mission to Mars.

The paradigm held a powerful grip on NASA (founded in 1958) and still lurks behind current plans to return to the Moon and mount a crewed expedition to Mars. The reality of space history shows that it has been modified, abandoned, rediscovered, and modified again over the decades. The first modification came with the Soviet launch of Sputnik in 1957, which prompted a swift response from the United States. In the desire to get a human being in space quickly, the United States shelved a program to develop winged, piloted spacecraft, extending research being done with aircraft like the X-15. The result was a series of ballistic, wingless “capsules”: Mercury, Gemini, and Apollo, with only limited ability to maneuver using aerodynamic forces. But the winged, aerodynamic paradigm did not die: it was resurrected as the space shuttle, first flown in 1981 and piloted to a landing using controls that were an extension of the X-15’s. Current plans call for a return to a ballistic capsule, but there are also plans for commercial access to space with winged vehicles, including the Burt Rutan design for ships that will carry paying passengers at least to the edge of space.

 North American X-15

The North American X-15, a rocket-powered research aircraft, bridged the gap between manned flight in the atmosphere and space flight.

Space Shuttle Enterprise

The first Space Shuttle orbiter, Enterprise, is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for space flight.

SpaceShipOne

SpaceShipOne, the first privately built and piloted vehicle to reach space.

NASA and private companies are now proposing spacecraft of a variety of designs to replace the shuttle, which will be retired soon. Some proposals called for winged, reusable craft, others for ballistic capsules. It will be interesting to see how the “von Braun Paradigm” plays out in the coming years.
