Key takeaways

  • James van Hoften belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect James van Hoften to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of James van Hoften from memory before moving on to harder problems.

Reference excerpt

James Dougal Adrianus "Ox" van Hoften (born June 11, 1944) is an American civil and hydraulic engineer, retired U.S. Navy officer and aviator, and a former astronaut for NASA.

Personal data Van Hoften was born June 11, 1944, in Fresno, California. He was active in the Boy Scouts of America where he achieved its second-highest rank, Life Scout. He considers Burlingame, California, to be his hometown. He is of Dutch descent. Van Hoften is married to the former Vallarie Davis of Pasadena, with three children. He enjoys skiing, playing handball and racquetball, and jogging. In college, he was a member of the Alpha Sigma chapter of Pi Kappa Alpha.

Education Graduated from Mills High School, Millbrae, California, in 1962; received a Bachelor of Science degree in civil engineering from the University of California, Berkeley in 1966; a Master of Science and a Doctor of Philosophy degree in hydraulic engineering from Colorado State University in 1968 and 1976, respectively.

Flight experience From 1969 to 1974, Van Hoften was a pilot in the United States Navy. He received flight training at Pensacola, Florida, and completed jet pilot training at Beeville, Texas, in November 1970. He was then assigned to the Naval Air Station, Miramar, California, to fly F-4 Phantoms, and subsequently to VF-121 Replacement Air Group. As a pilot with VF-154 assigned to the aircraft carrier USS Ranger in 1972, Van Hoften participated in two cruises to Southeast Asia where he flew approximately 60 combat missions during the Vietnam War. He resumed his academic studies in 1974, and completed a dissertation on the interaction of waves and turbulent channel flow for his doctorate. In September 1976, he accepted an assistant professorship of Civil Engineering at the University of Houston, and until his selection as an astronaut candidate, taught fluid mechanics and conducted research on biomedical fluid flows concerning flows in artificial internal organs and valves. Dr. Van Hoften has published a number of papers on turbulence, waves, and cardiovascular flows. From 1977 until 1980 he flew F-4N's with Naval Reserve Fighter Squadron 201 at NAS Dallas and then three years as a member of the Texas Air National Guard with the 147th Fighter Interceptor Group at Ellington Field as a pilot in the F-4C. He has logged 3,300 hours flying time, the majority in jet aircraft.

NASA career Dr. Van Hoften was selected as an astronaut candidate by NASA in January 1978. He completed a 1-year training and evaluation period in August 1979. From 1979 through the first flight, STS-1, Van Hoften supported the Space Shuttle entry and on-orbit guidance, navigation and flight control testing at the Flight Systems Laboratory at Downey, California. Subsequently, he was lead of the Astronaut Support Team at Kennedy Space Center, Florida, responsible for the Space Shuttle turn-around testing and flight preparations. He served as a mission specialist on STS-41-C in 1984, and STS-51-I in 1985. Dr. Van Hoften has logged a total 338 hours in space, including 22 hours of EVA flight time.

Spaceflight experience

STS-41-C: Challenger (April 6–13, 1984) was launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. During the 7-day mission the crew successfully deployed the Long Duration Exposure Facility (LDEF); retrieved the ailing Solar Maximum Mission satellite, repaired it on board the orbiting Challenger and replaced it in orbit, using the robot arm called the Remote Manipulator System (RMS). The mission also included flight testing of Manned Maneuvering Units (MMU's) in two extra-vehicular activities (EVA's); operation of the Cinema 360 and IMAX Camera Systems, as well as a Bee Hive Honeycomb Structures student experiment. The mission was accomplished in 107 Earth orbits in 167 hours, 40 minutes, 7 seconds. STS-51-I: Discovery (August 27 to September 3, 1985) launched from the Kennedy Space Center, Florida, and returned to land at Edwards Air Force Base, California. During this mission, the crew successfully deployed three communications satellites, the Navy's Syncom IV-4, Australian AUSSAT, and American Satellite Company's ASC-1. The crew also performed the successful salvage of the ailing Navy Syncom IV-3 satellite. These tasks included two extravehicular activities (EVA's) in which Dr. Van Hoften attached to the Remote Manipulator System (RMS) performed the first manual grapple and manual deployment of a satellite in orbit. The mission also included the Physical Vapor Transport of Organic Solids (PVTOS), the second material processing experiment to be flown aboard a Shuttle for 3M. The mission was accomplished in 112 orbits of the Earth in 171 hours, 17 minutes, 42 seconds.

Post-NASA career Dr. Van Hoften is a former senior Vice President and partner of the Bechtel Corporation. He was managing director of the global airport design and construction business and was responsible for airport developments in the Middle East, Japan, and North and South America. In the early 1990s, he was the program manager of the $23 billion Hong Kong Airport Core Programme including the new Hong Kong Airport. He later acted as Director of Projects for the UK National Air Traffic Services. In 2009 he was appointed a non-executive director of Gatwick Airport.

Worked examples

Example 1 — a first encounter with James van Hoften

Start with the simplest possible case. Write down what James van Hoften claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to James van Hoften before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about James van Hoften ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of James van Hoften

In research
James van Hoften appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses James van Hoften in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
James van Hoften is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1944 births, 1984 in spaceflight, 1985 in spaceflight, so understanding it makes those chapters shorter.
In everyday life
Look for James van Hoften outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
