Judith Love Cohen: The Woman Who Helped Save Apollo 13 While in Labor

Introduction

Judith Love Cohen was an American aerospace engineer whose work played an important role in NASA’s Apollo program. She is best known for helping design a backup navigation system called the Abort Guidance System, which contributed to the safe return of the Apollo 13 astronauts after a critical in-flight failure. Her story became widely known not only for her engineering achievements, but also for the remarkable moment she was reportedly working on key calculations while in labor with her son, actor Jack Black.

Early Life and Education

Judith Love Cohen was born in Brooklyn, New York, in 1933. From an early age, she showed strong interest in mathematics and science, even though opportunities for women in engineering were extremely limited at the time.

When she asked about studying advanced math and engineering, she was discouraged from pursuing technical fields and guided toward more traditional expectations for women. Despite this, she enrolled at Brooklyn College and entered the engineering program, where she was one of the only women in her classes.

She later transferred to the University of Southern California, where she completed both her bachelor’s and master’s degrees in engineering. In the 1950s, women made up only a very small percentage of engineering graduates, making her academic path highly uncommon for her generation.

Beginning of Her Engineering Career

After graduating, Judith entered the aerospace industry during a period when the United States was rapidly developing space technology. She joined TRW Inc., a major aerospace contractor that worked closely with NASA.

Her work focused on guidance and control systems for spacecraft, requiring advanced knowledge of orbital mechanics, electronics, and systems engineering. These systems were essential for ensuring spacecraft could navigate accurately in space.

Work on the Abort Guidance System

Judith Love Cohen’s most important contribution was the development of the Abort Guidance System for the Apollo Lunar Module.

This system was designed as a backup. If the main navigation computer failed during a mission, the Abort Guidance System would take over and help guide astronauts safely back to Earth or stabilize the spacecraft in critical situations.

The system required extremely precise engineering. It had to function reliably in space conditions where errors could not be corrected manually. Its purpose was to act as a final safeguard in life-threatening emergencies.

Working During Pregnancy

In 1968, Judith was working on final calculations for the Abort Guidance System while nine months pregnant.

According to accounts shared by her family and colleagues, she continued reviewing engineering work at her desk even in the final days of her pregnancy. When she went into labor, she reportedly took her work papers with her to the hospital.

Between contractions, she continued working on the calculations and identified a final issue that needed correction in the system design. She fixed the problem before delivering her child.

Shortly after, she gave birth to her son, Thomas Jacob Black, who later became known as actor Jack Black.

Apollo 13 Mission

In April 1970, NASA launched the Apollo 13 mission. During the journey to the Moon, a critical oxygen tank explosion severely damaged the spacecraft, putting the astronauts in danger.

The crew had to move into the Lunar Module, which was not originally designed to support them for an extended emergency return to Earth. In this situation, backup systems became essential for survival.

The Abort Guidance System helped support navigation and trajectory adjustments during the return journey. Its reliability contributed to the astronauts being able to safely return to Earth after the crisis.

NASA engineers later confirmed that backup systems like this were crucial in the success of the emergency recovery.

Later Career and Contributions

After the Apollo program, Judith Love Cohen continued working in aerospace engineering. She contributed to several major projects, including systems for the Hubble Space Telescope and satellite communications networks.

She also became an advocate for science education, particularly encouraging young women to pursue careers in engineering. She wrote children’s books designed to introduce girls to science and technology fields.

Her message focused on accessibility and representation, emphasizing that young girls needed visible role models in technical careers.

Personal Life

Judith Love Cohen balanced her engineering career with raising four children. Her family often described her as someone who combined scientific discipline with creativity and artistic interests, including ballet.

Her son, Jack Black, later spoke publicly about her achievements, highlighting both her engineering work and the extraordinary circumstances surrounding his birth.

Legacy

Judith Love Cohen passed away in 2016 at the age of 82. Her legacy continues through her contributions to aerospace engineering and her efforts to inspire future generations.

She is remembered for her work on critical NASA systems, her role in supporting the Apollo 13 mission, and her advocacy for women in STEM fields.

Her life story reflects both technical achievement and personal determination in an era when women in engineering were rare.

Conclusion

Judith Love Cohen’s story stands as an example of dedication, skill, and persistence. From working in a male-dominated field to contributing to space missions that defined human exploration, her impact remains significant.

Her work helped ensure the safety of astronauts in one of NASA’s most dangerous missions, and her efforts continue to inspire engineers and students today.
