He is married to Laura Jean Doell (originally from Scotia, New York), and together they have two children.

In his leisure time, Phillips enjoys outdoor activities including skiing, swimming, kayaking, and hiking.

Youth and Education

Phillips graduated from Scottsdale High School in Arizona in 1966. United States Naval Academy, earning a Bachelor of Science degree in mathematics and Russian in 1972. He graduated second in a class of 906 midshipmen.

After his undergraduate studies, Phillips pursued graduate education:

• Master of Science in Aeronautical Systems, University of West Florida (1974)

• Master of Science and PhD in Geophysics / Space Physics, University of California, Los Angeles (UCLA), in 1984 and 1987 respectively

His doctoral research focused on solar wind interactions and space physics, titled Interplanetary Magnetic Field Effects on the Interaction of the Solar Wind with Venus.

Military Service & Early Career

Upon graduation from the Naval Academy, Phillips was commissioned as an Ensign in the U.S. Navy in 1972. Naval Aviator.

He flew the A-7 Corsair II light attack aircraft aboard aircraft carriers, including tours with Attack Squadron 155 (VA-155) aboard the USS Oriskany and USS Franklin D. Roosevelt.

Over his naval flying career, Phillips logged over 4,400 flight hours and conducted approximately 250 aircraft carrier landings.

In 1982, he transferred from active duty to the U.S. Navy Reserve, while pursuing graduate studies and later a scientific research career.

Later, Phillips held a J. Robert Oppenheimer Postdoctoral Fellowship at Los Alamos National Laboratory beginning in 1989, where he advanced research in solar physics and plasma environments of space.

He also served as Principal Investigator for the Solar Wind Plasma Experiment aboard the Ulysses spacecraft from 1993 to 1996, contributing to our understanding of the Sun’s polar environment.

NASA & Astronaut Career

Selection and Early NASA Roles

Phillips was selected by NASA in April 1996 as part of Astronaut Group 16 (nicknamed “The Sardines”) — the largest astronaut class to date at that time. Astronaut Office, including systems engineering, CAPCOM for the ISS, and robotics support.

He also served as a backup crew member for Expedition 7.

Spaceflight Missions

Phillips flew three major missions in his NASA career:

1. STS-100 (Space Shuttle Endeavour) — April 19 to May 1, 2001

   • During this 12-day mission to the ISS, the crew installed the Canadarm2 robotic arm, and transferred supplies and experiments aboard the Multi-Purpose Logistics Module Raffaello.

   • Phillips served as Ascent/Entry Flight Engineer and Intravehicular Activity (IVA) coordinator during two spacewalks.

2. Expedition 11 (Soyuz TMA-6 / ISS stay) — April 15 to October 11, 2005

   • Phillips launched aboard Soyuz TMA-6 with Sergei Krikalev and Roberto Vittori to the ISS, serving as Flight Engineer and NASA Science Officer.

   • On June 14, 2005, he became the first person to testify before the U.S. Congress from space, via live video feed, discussing the role of the ISS as an orbital laboratory.

   • Phillips and Krikalev performed a 5-hour spacewalk on August 18, retrieving experiments and installing a video camera to assist with docking operations.

   • The crew returned to Earth aboard Soyuz TMA-6 on October 11, 2005.

3. STS-119 (Space Shuttle Discovery) — March 15 to 28, 2009

   • This mission delivered and installed the S6 truss segment, the final set of solar arrays and batteries for the ISS structure.

   • Phillips contributed to the assembly and integration tasks during the mission’s 12 days in orbit.

In total, Phillips has accumulated over 203 days, 17 hours, 22 minutes in space across his missions. one spacewalk, with approximately 4 hours, 57 minutes of EVA time.

Post-Flight Roles & Later Career

After his active spaceflight career, Phillips served in academia and leadership roles. From 2009 to 2011, he held the Smith/McCool NASA Chair Professorship at the U.S. Naval Postgraduate School in Monterey, California.

He officially retired from NASA in 2011.

Awards, Honors & Recognition

Throughout his distinguished career, Phillips has earned numerous honors:

• NASA Distinguished Service Medal

• NASA Space Flight Medal (with two award stars)

• National Defense Service Medal with two service stars

• Navy Sea Service Deployment Ribbon

• Navy Recruiting Service Ribbon

• He has also been recognized with NASA Group Achievement Awards (for contributions to the Ulysses mission) and the Los Alamos National Laboratory Distinguished Performance Award (1996)

Phillips is also cited in the Notable Graduates list at the U.S. Naval Academy for his astronaut role.

Personality, Approach, and Impact

John L. Phillips is often described as a methodical, rigorous scientist, and consummate professional aviator. His trajectory—from naval aviation through advanced space physics research into long-duration missions—reflects a dual commitment to discipline and curiosity.

He is an advocate for the role of the International Space Station as a laboratory in orbit, and his congressional testimony from ISS during Expedition 11 highlighted the significance of in-space science and human presence beyond Earth.

His contributions to robotics, systems engineering, and space station assembly reflect not just physical courage but deep technical acumen.

Phillips’s balance of operational skill and scientific insight marks him as a figure who helped bridge the gap between exploration and research in human spaceflight.

Selected Quotes & Reflections

While Phillips is not as widely quoted as some public figures, here are a few notable statements and reflections attributed to him:

• On speaking from space:
  “I became the first person to testify before Congress from space … the hearing was to evaluate the space station’s usefulness as an orbiting laboratory.”

• Reflecting on his career:
  His NASA bio emphasizes that he “has flown three different spacecraft types: shuttle, Soyuz and ISS.”

Because public quotations are relatively scarce, much of his impact is better expressed in his actions, mission leadership, and scientific publications rather than in pithy aphorisms.

Lessons from John L. Phillips

• Bridging disciplines matters: Phillips’s path from naval aviator to space scientist to astronaut shows how combining technical, operational, and scientific training broadens one’s contributions.

• Long-duration commitment: His decades-long trajectory—from training and research to spaceflights and post-flight mentorship—demonstrates that major achievements often arise from sustained effort over many years.

• Science in service of exploration: He used his missions not only for adventure but to further fundamental research, especially in solar and space physics.

• Advocacy within the mission: By testifying before Congress from the ISS, Phillips demonstrated that astronauts can be voices for the value of human space presence and scientific return.

• Legacy through infrastructure: His work on ISS assembly, robotic systems, and operations helps form part of the bedrock upon which future human missions (to the Moon, Mars, beyond) will build.

Conclusion

John L. Phillips stands as a paragon of what it means to be both an explorer and a scientist. Through rigorous training, courageous missions, and steady intellectual engagement, he helped expand humanity’s reach into space while advancing knowledge of the solar environment and station operations.

His story reminds us that spaceflight is not just spectacle—but a domain where discipline, curiosity, and persistence converge.
