Joylette Goble: Her NASA Career, Family & Books

Joylette Goble, also known as Joylette Goble Hylick and Joylette Hylick, is a mathematician, retired information technology professional and author. She is the eldest daughter of Katherine Johnson, the NASA mathematician whose work became widely known through Hidden Figures.

Joylette built a technical career of her own, working at NASA’s Langley Research Center and later at Lockheed Martin. She also helped bring her mother’s experiences to readers through two books published in 2021. Her public appearances connect that family history with a practical message: children should have opportunities to develop their interests in mathematics and science.

Joylette Goble at a Glance

The different versions of her name refer to the same person. Her books generally use Joylette Hylick, while university event announcements also use Joylette Goble Hylick.

From a Musical Childhood to a Mathematics Degree

Music was an important part of Joylette’s childhood. In a family interview published during the One Step Further book tour, she recalled playing piano for her school’s glee club and learning violin in eighth grade. Her mother directed a church choir, and the family played several instruments.

Music also provided comfort during her father’s illness. Joylette remembered spending time at the hospital and finding reassurance in the rhythms she understood through performing.

In 1958, she received a partial music scholarship to Hampton. She chose mathematics as her major while continuing to sing, play piano and organ, and help conduct the choir. She later performed on the instruments in Hampton’s Ogden Hall. These recollections appear in the family’s book-tour interview.

Her education continued beyond her undergraduate degree. A professional biography published by Boys & Girls Clubs of Mercer County confirms her B.A. in Mathematics from Hampton University and M.S. in Information Systems from Drexel University.

Her Work at NASA and Lockheed Martin

Joylette’s professional background combines mathematics with information technology. The Mercer County biography states that she spent more than 30 years at NASA Langley Research Center in Virginia and eventually retired from Lockheed Martin.

The author biography accompanying her 2021 book-tour interview identifies her later position as Senior Requirements Engineer at Lockheed Martin. It also confirms that she previously worked at NASA as a mathematician.

Those sources establish her employers and professional fields, but they do not provide a complete chronology of assignments or identify the missions she worked on. Specific spacecraft calculations should therefore be attributed to her only when a supporting record exists.

Her mother’s work is documented separately. NASA’s biography of Katherine Johnson describes Katherine’s calculations for Alan Shepard’s flight and her verification of the computer calculations for John Glenn’s 1962 orbital mission. Those achievements belong to Katherine’s career.

Parents and Sisters

Joylette grew up in a family shaped by teaching, music and mathematics. Her parents, Katherine and James Goble, married in November 1939. According to the Katherine Johnson Foundation’s family biography, they met at Katherine’s first teaching job.

James died in December 1956 after a prolonged illness. Katherine later married James “Jim” Johnson, who became Joylette’s stepfather. The two men are sometimes confused because they shared a first name.

Katherine Johnson’s Work and Life at Home

Katherine began working at Langley in 1953, when the organization was the National Advisory Committee for Aeronautics, or NACA. Her career continued at NASA until her retirement in 1986.

Joylette’s memories add a family perspective to that professional record. In a 2017 Alvernia University interview project, she explained that she had not fully appreciated the significance of her mother’s work until later in life. Katherine’s humility helped explain why her children’s understanding of her achievements developed gradually.

This perspective gives readers something that a list of space missions cannot: an account of how an internationally recognized scientist was understood by her own family before widespread fame arrived.

Constance and Katherine Moore

The sisters’ birth order is clear in the foundation’s account: Joylette was the eldest, Constance was the middle child, and Katherine was the youngest.

Constance, usually called Connie, worked in education and also established Connie’s Trucking. Her Daily Press obituary records her death on May 4, 2010, and describes her years teaching in Virginia and Louisiana.

Katherine Goble Moore, known as Kathy, worked as a teacher and guidance counselor. She later collaborated with Joylette on books about their mother. Both women appeared together at a tribute in Bluefield, Virginia, in August 2025, according to local broadcaster WVVA.

Books Co-Authored by Joylette Goble Hylick

Joylette’s authorship has made family memories available to audiences of different ages. Two publications are particularly useful for understanding her contribution.

One Step Further

One Step Further: My Story of Math, the Moon, and a Lifelong Mission was published on January 5, 2021. National Geographic’s publisher listing credits Katherine Johnson, Joylette Hylick and Katherine Moore, with illustrations by Charnelle Pinkney Barlow.

The picture book combines Katherine’s account with her daughters’ recollections. Its family photographs and illustrations introduce young readers to education, racial barriers and the opportunities that connected successive generations.

The publisher lists an intended age range of four to eight. Its format gives younger children an accessible introduction to the family’s experiences, including Joylette’s own path toward becoming a NASA mathematician.

My Remarkable Journey

My Remarkable Journey: A Memoir appeared in May 2021, following Katherine Johnson’s death in February 2020. It is Katherine’s memoir, written with the assistance of Joylette Hylick, Katherine Moore and writer Lisa Frazier Page.

A Physics Today review includes all four names in its bibliographic credit. Recognizing Page’s contribution gives a more complete account of the collaboration.

The memoir allows more room than a picture book for Katherine’s education, family experiences and professional life. Joylette’s involvement helped preserve a personal account alongside the history already familiar to audiences of Hidden Figures.

Public Appearances and Recent Activities

Joylette has continued sharing her mother’s story through educational events and commemorations.

The Katherine Johnson Papers at WVU

West Virginia University listed Joylette and Katherine Moore as featured speakers for its September 29, 2023, celebration marking the opening of the Katherine Goble Johnson Papers. The official event announcement also advertised a memoir signing and displays of family materials.

The archive’s collection guide describes photographs, correspondence, awards, honorary degrees, news coverage and fan mail. Much of the material concerns the attention surrounding the 2016 film Hidden Figures, alongside records of Katherine’s earlier life and family history.

For readers seeking a deeper account, the archive provides a route to original records. Its materials help document both Katherine’s achievements and the public response when those achievements became widely recognized.

A Return to Bluefield in 2025

WVVA reported in August 2025 that Joylette and her sister returned to Bluefield for the unveiling of two historical plaques. One commemorated their mother’s teaching; the other marked the site where Katherine and James Goble had begun raising their family.

The sisters shared memories during the ceremonies. Joylette spoke about the continuing effect of her mother’s story on children, teachers and other audiences. The event connected Katherine’s early work in education with the scientific career that later brought her international recognition.

Meeting Schoolchildren

A more recent Cole Manor Elementary School account, visible in the school’s 2026 updates, describes a visit by Joylette and her son, a retired teacher.

The school reported that third graders had written letters during a learning module about space. Joylette responded to their interest with a presentation. It is a concrete example of how she continues to share the family’s experiences directly with young students.

Husband, Children and Personal Details

A family obituary provides a limited but useful public reference to Joylette’s marriage. Connie’s 2010 obituary lists her sister as Joylette Hylick (Lawrence), identifying her spouse at that time. It does not establish a wedding date or her present marital circumstances.

The Cole Manor school account confirms that she has a son. It does not provide a complete account of her children or family life.

Her exact birth date and net worth were not established by the reliable sources reviewed. Those gaps should remain explicit rather than being filled with an estimated birthday, income or fortune.
