Gus Grissom

Gus Grissom is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gus Grissom rather than just read about it. In short: Virgil Ivan "Gus" Grissom (April 3, 1926 – January 27, 1967) was an American astronaut, and one of the original Mercury Seven selected by the National Aeronautics and Space Administration (NASA) for Project Mercury, a program to train and launch astronauts into outer space. Grissom went on to be a Project Gemini and Apollo program astronaut for NASA.

Key takeaways

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

Reference excerpt

Virgil Ivan "Gus" Grissom (April 3, 1926 – January 27, 1967) was an American astronaut, and one of the original Mercury Seven selected by the National Aeronautics and Space Administration (NASA) for Project Mercury, a program to train and launch astronauts into outer space. Grissom went on to be a Project Gemini and Apollo program astronaut for NASA. As a member of the NASA Astronaut Corps, Grissom was the second American to fly in space in 1961. He was also the second American to fly in space twice, preceded only by Joe Walker with his sub-orbital X-15 flights. Grissom was a World War II and Korean War veteran, mechanical engineer, and United States Air Force test pilot. He was a recipient of the Distinguished Flying Cross, the Air Medal with an oak leaf cluster, two NASA Distinguished Service Medals, and, posthumously, the Congressional Space Medal of Honor. As commander of AS-204 (Apollo 1), Grissom died with astronauts Ed White and Roger B. Chaffee on January 27, 1967, during a pre-launch test for the Apollo 1 mission at Cape Kennedy, Florida.

Early life Virgil Ivan Grissom was born in the small town of Mitchell, Indiana, on April 3, 1926, to Dennis David Grissom, a signalman for the Baltimore and Ohio Railroad, and Cecile King Grissom, a homemaker. Virgil was the family's second child; his older sister, Lena, died a year prior to Gus' birth. He was followed by three younger siblings: a sister, Wilma, and two brothers, Norman and Lowell. Grissom started school at Riley grade school. His interest in flying began during that time, building model airplanes. He received his nickname when his friend was reading his name on a scorecard upside down and misread "Griss" as "Gus". As a youth, Grissom attended the local Church of Christ, where he remained a lifelong member. He joined the local Boy Scout Troop and earned the rank of Star Scout. Grissom credited the Scouts for his love of hunting and fishing. He was the leader of the honor guard in his troop. His first jobs were delivering newspapers for The Indianapolis Star in the morning and the Bedford Times in the evening. In the summer he picked fruit in area orchards and worked at a dry-goods store. He also worked at a local meat market, a service station, and a clothing store in Mitchell. Grissom started attending Mitchell High School in 1940. He wanted to play varsity basketball but he was too short. His father encouraged him to find sports he was more suited for, and he joined the swimming team. Although he excelled at mathematics, Grissom was an average high school student in other subjects. He graduated from high school in 1944. In addition, Grissom occasionally spent time at a local airport in Bedford, Indiana, where he first became interested in aviation. A local attorney who owned a small plane would take him on flights and taught him the basics of flying.

World War II World War II began while Grissom was still in high school, but he was eager to join the armed services upon graduation. Grissom enlisted as an aviation cadet in the U.S. Army Air Forces during his senior year in high school, and completed an entrance exam in November 1943. Grissom was inducted into the U.S. Army Air Forces on August 8, 1944, at Fort Benjamin Harrison, Indiana. He was sent to Sheppard Field in Wichita Falls, Texas, for five weeks of basic flight training, and was later stationed at Brooks Field in San Antonio, Texas. In January 1945 Grissom was assigned to Boca Raton Army Airfield in Florida. Although he was interested in becoming a pilot, most of Grissom's time before his discharge in 1945 was spent as a clerk.

Post-war employment Grissom was discharged from military service in November 1945, after the war had ended, and returned to Mitchell, where he took a job at Carpenter Body Works, a local bus manufacturing business. Grissom was determined to make his career in aviation and attend college. Using the G.I. Bill for partial payment of his school tuition, Grissom enrolled at Purdue University in September 1946. Due to a shortage of campus housing during her husband's first semester in college in West Lafayette, Indiana, Grissom's wife, Betty, stayed in Mitchell living with her parents, while Grissom lived in a rented apartment with another male student. Betty Grissom joined her husband on campus during his second semester, and the couple settled into a small, one-bedroom apartment. Grissom continued his studies at Purdue, worked part-time as a cook at a local restaurant, and took summer classes to finish college early, while his wife worked the night shift as a long-distance operator for the Indiana Bell Telephone Company to help pay for his schooling and their living expenses. Grissom graduated from Purdue with a Bachelor of Science degree in mechanical engineering in February 1950.

Worked examples

Example 1 — a first encounter with Gus Grissom

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

In research
Gus Grissom appears in physics 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 Gus Grissom 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
Gus Grissom is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 1961 in spaceflight, 1965 in spaceflight, so understanding it makes those chapters shorter.
In everyday life
Look for Gus Grissom 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.
