Key takeaways

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

Reference excerpt

Glynn Stephen Lunney (November 27, 1936 – March 19, 2021) was an American NASA engineer. Lunney was an employee of NASA since its creation in 1958, a flight director during the Gemini and Apollo programs. Lunney was on duty during historic events such as the Apollo 11 lunar ascent and the pivotal hours of the Apollo 13 crisis. At the end of the Apollo program, he became manager of the Apollo–Soyuz Test Project, the first collaboration in spaceflight between the United States and the Soviet Union. Later, he served as manager of the Space Shuttle program before leaving NASA in 1985 and later becoming a vice president of the United Space Alliance. Lunney was a key figure in the US human spaceflight program from Project Mercury through the coming of the Space Shuttle. He received numerous awards for his work, including the National Space Trophy, which he was given by the Rotary Club in 2005. Chris Kraft, NASA's first flight director, described Lunney as "a true hero of the space age", saying that he was "one of the outstanding contributors to the exploration of space of the last four decades".

Early life and NACA career Glynn Stephen Lunney was born in the coal city of Old Forge, Lackawanna County, Pennsylvania, on November 27, 1936, the eldest son of William Lunney, a welder and former miner who encouraged his son to get an education and to find a job beyond the mines, and his wife Helen Glynn Lunney. He graduated from the Scranton Preparatory School in 1953. A childhood interest in model airplanes prompted Lunney to study engineering in college. After attending the University of Scranton (1953–1955), he transferred to the University of Detroit, where he enrolled in the cooperative training program run by the Lewis Research Center in Cleveland, Ohio. The center was a part of the National Advisory Committee for Aeronautics (NACA), a United States federal agency founded to promote aeronautical research. Cooperative students at NACA took part in a program that combined work and study, providing a way for them to fund their college degrees while gaining experience in aeronautics. Lunney graduated from college in June 1958, with a Bachelor of Science degree in aerospace engineering. After graduation, Lunney remained with NACA. His first job was as a researcher in aerospace dynamics at Lewis Research Center, where he worked with a team studying the thermodynamics of vehicles during high-speed reentry. Using a B-57 Canberra bomber, the team sent small rockets high into the atmosphere in order to measure their heating profile.

NASA career

Mercury Only a month after Lunney graduated, President Eisenhower signed into existence the National Aeronautics and Space Administration (NASA), into which NACA was subsumed. His timing was perfect, for as Lunney later said, "there was no such thing as space flight until the month I got out of college". Lunney was soon transferred to Langley Research Center in Hampton, Virginia, where in September 1959 he became a member of the Space Task Group, which was the body given responsibility for the creation of NASA's human spaceflight program. Aged twenty-one, he was the youngest of the forty-five members of the group. His first assignment was with the Control Center Simulation Group, which planned the simulations used to train both flight controllers and astronauts for the as-yet unknown experience of human spaceflight.

A member of the Flight Operations Division, Lunney was one of the engineers responsible for planning and creating procedures for Project Mercury, America's first human spaceflight program. He took part in the writing of the first set of mission rules, the guidelines by which both flight controllers and astronauts operated. During Mercury, Lunney became, after Tecwyn Roberts, the second man to serve as the Flight Dynamics Officer (FIDO) in the Mercury Control Center, controlling the trajectory of the spacecraft and planning adjustments to it. Lunney's colleague Gene Kranz described him as "the pioneer leader of trajectory operations, who turned his craft from an art practiced by a few into a pure science". It was during these years that Lunney became the protege of flight director Chris Kraft. He was sometimes referred to as "the son of Chris Kraft." Lunney worked both in the Control Center and at remote sites; during the flight of John Glenn, America's first orbital spaceflight, he was serving as the FIDO in Bermuda. In September 1961, NASA's Space Task Group was reorganized into the Manned Spacecraft Center and moved to Houston, Texas, and Lunney moved with it. In Houston, he became head of the Mission Logic and Computer Hardware section, where he defined and oversaw the computing and display requirements of the flight dynamics division within the new Mission Control Center.

Gemini

Gemini was a step forward for NASA's human spaceflight program: the Gemini capsule was larger and more advanced than Mercury, capable of supporting two men for up to a two-week mission. Because of the longer mission durations, Mission Control began to be staffed in shifts. In 1964, Lunney and Kranz were selected by Kraft to join him and his deputy John Hodge as flight directors. Aged only twenty-eight, Lunney was the youngest of the four. Lunney was stationed in Bermuda for the uncrewed Gemini 2 mission. He worked backup on Gemini 3, taking charge of the newly established Mission Control Center in Houston, at a time when flights were still controlled from Cape Canaveral in Florida. On Gemini 4, he again was working backup, this time in Florida, supporting the first mission that was controlled entirely from Houston. After spending some time on uncrewed testing for the Apollo program, he returned to work as a flight director on Gemini 9 and Gemini 11 and lead flight director on, Gemini 10 and Gemini 12.

Apollo As with Project Mercury, Lunney was involved in Project Apollo right from the beginning. He took charge of the "boilerplate" tests of the Apollo abort escape system at White Sands, which took place during the Gemini program, and was flight director during the first uncrewed Saturn V test flight, SA-501.

Worked examples

Example 1 — a first encounter with Glynn Lunney

Start with the simplest possible case. Write down what Glynn Lunney claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Glynn Lunney 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 Glynn Lunney 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 Glynn Lunney

In research
Glynn Lunney appears in astronomy 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 Glynn Lunney 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
Glynn Lunney is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 2021 deaths, American aerospace engineers, so understanding it makes those chapters shorter.
In everyday life
Look for Glynn Lunney 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.
