Key takeaways

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

Reference excerpt

Ronald Ellwin Evans Jr. (November 10, 1933 – April 6, 1990) was an American electrical engineer, aeronautical engineer, officer and aviator in the United States Navy, and NASA astronaut. As Command Module Pilot on Apollo 17 he was one of the 24 Apollo astronauts to fly to the Moon, and one of the 12 to do so without landing. Before becoming an astronaut, Evans graduated with a Bachelor of Science degree in electrical engineering from the University of Kansas and joined the U.S. Navy in 1956. After receiving his naval aviator wings, he served as a fighter pilot and flew combat missions during the Vietnam War. In 1964 he received a Master of Science degree in aeronautical engineering from the U.S. Naval Postgraduate School. Achieving the rank of captain, he retired from the Navy in 1976. Evans was selected as an astronaut by NASA as part of NASA Astronaut Group 5 in 1966 and made his only spaceflight as command Module pilot aboard Apollo 17 in December 1972, the last crewed mission to the Moon, with Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt. During the flight, Evans and five mice orbited the Moon a record 75 times as his two crewmates descended to and explored the surface. He is the last person to orbit the Moon alone and, at 147 hours and 43 minutes, holds the record for the most time spent in lunar orbit. During Apollo 17's return flight to Earth, Evans performed an extravehicular activity (EVA) to retrieve film cassettes from the service module. It was the third "deep space" EVA, and is the spacewalk performed at the greatest distance from any planetary body. As of 2026, it remains one of only three deep space EVAs, all made during the Apollo program's J-missions. It was the final spacewalk of the Apollo program. In 1975, Evans served as backup Command Module Pilot for the Apollo–Soyuz Test Project mission. He worked on the development of the Space Shuttle before retiring from NASA in March 1977 to become a coal industry executive. Evans died from a heart attack in 1990, aged 56.

Early life and education Ronald Ellwin Evans was born on November 10, 1933, in St. Francis, Kansas, the son of Clarence Ellwin "Jim" Evans and his wife Marie A. (née Priebe). He had two younger siblings, Larry Joe Evans and Jay Evans. He was active in the Boy Scouts of America where he achieved its second highest rank, Life Scout. He attended St. Francis Elementary School. His father served in the United States Navy during World War II. Evans started his secondary education at St. Francis High School, but only attended for two months before the family moved to Topeka, Kansas to seek medical treatment for his brother Larry, who was diagnosed with liver cancer. Larry died in 1951, and his parents separated. Evans attended Highland Park High School in Topeka, where he served on the Student Council, and was the president of the Science Club. He was a member of the school American football team, and was an All-Conference guard. His other brother, Dale, secured a football scholarship to Kansas State University where he played college football, and later played professionally for the Denver Broncos. Later Dale served two tours of duty in Vietnam with the United States Marine Corps. Evans decided to study electrical engineering at the University of Kansas. His application was accepted, and he was offered a place starting in September 1951. His family had little money, so in order to pay for his college education he secured a scholarship from the Naval Reserve Officers Training Corps (NROTC). During the fraternities' rush week he joined the Sigma Nu fraternity. He earned extra money selling Chesterfield cigarettes, and had a cigarette vending machine installed in the Sigma Nu fraternity house. NROTC training involved a parade for one hour each week, and during the summer break there were midshipman cruises on warships. The first was on the battleship USS Wisconsin. In his sophomore year there was an introduction to naval aviation at Naval Air Station Corpus Christi in Texas. This experience inspired Evans to become a naval aviator. The third year cruise was to Europe on the USS Gwin, a destroyer minelayer. In his junior year he was elected to the Sigma Tau, Tau Beta Pi and Sigma Xi engineering honor societies. During his final summer break he worked in a glass factory to gain general engineering experience. He graduated with his Bachelor of Science degree in electrical engineering in June 1956.

Navy In a letter dated December 12, 1955, the Navy offered Evans a commission as an ensign and designated him a student aviator. He reported to Naval Air Station Pensacola in February 1956 for basic flight training in the Beechcraft T-34 Mentor, and made his first solo flight on May 21. He then progressed to the more powerful North American T-28 Trojan. His flight training then moved to Naval Outlying Landing Field Barin in Alabama, where student aviators practised landing on an aircraft carrier using an outline painted on the runway in the old North American T-6 Texan (known as the SNJ). Six actual landings were then made on the aircraft carrier USS Saipan. Evans returned to Topeka for Christmas leave. There he met Janet Merle (Jan) Pollom, who worked as a secretary at Forbes Air Force Base, and fell in love with her. On January 4, 1957, he reported to Naval Air Station Memphis, where he was taught instrument flying, culminating in a ground-controlled approach test. He then learned how to fly a jet aircraft, the Lockheed T-33 Shooting Star. In a ceremony on April 12 attended by Pollom, her mother, and Evans's mother, the chief of the Naval Air Technical Training Command, Rear Admiral Frank P. Akers handed out certificates to Evans's class designating them as naval aviators. Pollom pinned his aviator wings on his uniform.

Worked examples

Example 1 — a first encounter with Ronald Evans (astronaut)

Start with the simplest possible case. Write down what Ronald Evans (astronaut) 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 Ronald Evans (astronaut) 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 Ronald Evans (astronaut) 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 Ronald Evans (astronaut)

In research
Ronald Evans (astronaut) 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 Ronald Evans (astronaut) 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
Ronald Evans (astronaut) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 births, 1990 deaths, 20th-century American businesspeople, so understanding it makes those chapters shorter.
In everyday life
Look for Ronald Evans (astronaut) 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.
