Reference excerpt

Marjorie Trees Townsend (née Rhodes; March 12, 1930 – April 4, 2015) was an American electrical engineer, and the first woman to manage a spacecraft launch for NASA.

Early life and education Marjorie Trees Rhodes was born in Washington, D. C. At age 15 she started college, and was the first woman to earn an engineering degree from George Washington University when she graduated in 1951.

Career Early in her career, Townsend worked for the National Institute of Standards and Technology, and at the Naval Research Laboratory. She joined NASA in 1959. Her early work there involved weather satellites such as TIROS-1 and Nimbus. In time she was the first woman to become a spacecraft project manager at Goddard Spaceflight Center, responsible for Uhuru, the first satellite designed for x-ray astronomy. It was also the first American spacecraft to be launched from outside the United States, in 1970. She worked with Bruno Rossi and Nobel laureate Riccardo Giacconi on the Small Astronomy Satellite program, and went to Kenya when Uhuru was launched by the Italian space program from the San Marco platform there. Townsend retired from NASA in 1980, having received the Exceptional Service Medal and Outstanding Leadership Medal for her work. After that, she served as director of space systems engineering for BDM International, and was vice president at Space America. She retired from her private-sector work in 1996. Townsend was co-inventor of a digital telemetry system, patented in 1968, which was part of the Nimbus program weather satellite.

Honors and professional service Marjorie Townsend was president of the Washington Academy of Sciences. She was a fellow of the Institute of Electrical and Electronics Engineers, and chaired a local chapter of the American Institute of Aeronautics and Astronautics. In 1972 she was named a Knight of the Italian Republic Order for her work on Uhuru. She was named a Distinguished Alumnus of George Washington University in 1976. In 2006 she was inducted into the Engineering Hall of Fame at her alma mater.

Personal life and legacy Marjorie Rhodes married Charles E. Townsend Sr., a medical student, in 1948. The couple had four sons together, and lived in the Cleveland Park neighborhood of Washington DC. Marjorie was widowed in 2001. The Marjorie Rhodes Townsend Papers are held in the Special Collections library at Virginia Polytechnic Institute and State University.

Worked examples

Example 1 — a first encounter with Marjorie Townsend

Start with the simplest possible case. Write down what Marjorie Townsend 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 Marjorie Townsend 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 Marjorie Townsend 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 Marjorie Townsend

In research: Marjorie Townsend 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 Marjorie Townsend 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: Marjorie Townsend is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1930 births, 2015 deaths, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Marjorie Townsend 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.
