Edward C. Stone, renowned for his management of the Voyager spacecraft objectives and his function ahead of time area and planetary astronomy at Caltech and W. M. Keck Observatorydeveloping the Institute’s Area Radiation Labserving in recognized management functions, and leading the way for the next generation of huge telescopes.

Constantly bringing a sense of marvel, an encyclopedic understanding, and a spirit of expedition to his work, Stone led the Voyager task through its trip of the external worlds– an amazing journey that consisted of the very first encounter with volcanism outside Earth in 1979– and through its later years when both spacecraft made history by crossing into interstellar area in 2012 and 2018.
” Ed Stone was a male in continuous movement, chasing after the unidentified, similar to the area objectives he directed,” states Caltech President Thomas F. Rosenbaum, the Sonja and William Davidow Presidential Chair and teacher of physics. “An excellent researcher, a powerful leader, and a talented expositor of discovery, Ed will be missed out on sorely by all who he motivated at Caltech and in the astronomy neighborhood at big. “
Management at JPL and Beyond
In 1991, Stone was called director of the Jet Propulsion Laboratory( JPL), which is handled by Caltech for NASA. He stayed because function up until May 2001, throughout which time he supervised 21 various objectives and instruments, consisting of the< period aria-describedby=" tt" data-cmtooltip="

” Ed will be kept in mind as an energetic leader and researcher who broadened our understanding about deep space– from the Sun to the worlds to far-off stars– and stimulated our cumulative creativities about the secrets and marvels of deep area,” states Laurie Leshin (PhD’ 95), JPL director and Caltech vice president. “Ed’s discoveries have actually sustained expedition of formerly hidden corners of our planetary system and will influence future generations to reach brand-new frontiers. He will be considerably missed out on and constantly kept in mind by the NASA, JPL, and Caltech neighborhoods and beyond. “
Pioneering Ground-Based Astronomy
Stone’s work to open the limits of area to expedition exceeded area objectives. From 1983 to 1988, he worked as chair of the Division of Physics, Mathematics and Astronomy at Caltech. While because function, he supervised the facility of the Laser-Interferometer Gravitational-wave Observatory (< period aria-describedby=" tt "data-cmtooltip= "

As part of his management functions there in the mid 1980s through the 1990s, he managed the building of the W. M. Keck Observatory, among the most efficient ground-based huge observatories worldwide. He was likewise on the board of the W. M. Keck Foundation.
Motivated by the frustrating success of Keck, Stone ended up being associated with the Thirty Meter Telescope( TMT)a huge telescope proposed to live, like Keck, atop Maunakea in Hawai’i. Stone signed up with the TMT Corporation in 2004, and ended up being the founding executive director of the TMT International Observatory LLC in 2014, a function he stayed in till 2022.
“It is tough for me to consider any researcher today with a clinical tradition as broad and diverse as Ed’s,” states Fiona A. Harrison, the Kent and Joyce Kresa Leadership Chair for the Division of Physics, Mathematics and Astronomy, and Harold A. Rosen Professor of Physics. “He made significant contributions to cosmic ray and area physics, planetary expedition, solar physics and ground-based astronomy. His understanding was encyclopedic and his interest for checking out the universes unbounded. Personally, he affected me exceptionally as a coach, coworker, and co-leader of the Space Radiation Lab and I currently miss his suggestions and relationship greatly. “
Early Life and Education
Born in Knoxville, Iowa, on January 23, 1936, Stone matured on the banks of the Mississippi River in close-by Burlington, Iowa, and got his undergraduate education at Burlington Junior College( now Southeastern Community College).” Our daddy was a building and construction superintendent who delighted in discovering brand-new things and discussing how they worked,” he composed in an autobiography upon being granted the 2019 Shaw Prize in Astronomya prominent honor bestowed for his management in the Voyager task.
“As a housewife, our mom produced a warm, inviting, and supporting area for our household,” Stone composed. “Both moms and dads had a strong work principles … They motivated my pursuit of clinical and technical activities such as constructing radios and other electronic devices. My physics instructor even more advanced my clinical and laboratory experience and it was because of his prompting that I registered at the Area Radiation Lab at Caltech, which continues to play a crucial function in lots of astrophysics area objectives.
In 1972, supervisors at JPL used Stone the position of task researcher of the Voyager objective.
“I have actually understood Ed Stone for 57 years and I worked carefully with him on nearly an everyday basis for the last 51 years. I feel he is the most intelligent male I ever fulfilled,” states Alan Cummings, senior research study researcher for the Space Radiation Lab. Cummings started working together with Stone as a college student in the 1960s. “He was a remarkable researcher, as evidenced by him winning the Shaw Prize, to name a few awards and honors. He was a terrific multi-tasker, for instance, being JPL director for 10 years while at the very same time dealing with me on a day-to-day– well, mainly nighttime– basis on our Voyager information. He was my manager, my associate, and my good friend, and I will miss him significantly.”
A Grand Tour
The Voyager objective was created to make the most of an uncommon positioning of video honoring the 40th anniversary of Voyager“Time after time, we simply discovered that nature was far more innovative than our designs.”
Master of Space Missions
In addition to handling numerous objectives while director of JPL, Stone likewise assisted reorganize numerous tasks to keep them afloat in the middle of financing cuts. In the 1990s, after the Cold War, NASA and defense spending plans were considerably cut. Throughout this time, Stone managed the redesign of the cooling system on NASA’s infrared observatory, the Spitzer Space Telescope, making it more expense reliable. As an outcome, Spitzer ran from 2003 to 2020, and made numerous discoveries, such as exposing that the TRAPPIST-1 system includes 7 Earth-size worlds
Beyond his administrative tasks at JPL, Stone worked as either a primary private investigator or science instrument lead on 9 NASA objectives and as a co-investigator (a considerable science instrument employee) on 5 others. Among these objectives, the Parker Solar Probewhich released in 2018, continues to whip around the Sun to study the source of its solar wind– the very same wind that sculpts a bubble, called the heliosphere, around the Sun, from which Voyager 1 and 2 left. “In 2012, Voyager 1 lastly left the bubble initially anticipated by Parker, going into interstellar area,” Stone stated in a Caltech function story about the objective, which is called after Caltech alumnus Eugene Parker (PhD ’51).
Suzanne Dodd, who has actually worked as Voyager job supervisor considering that 2010, remembers Stone’s calm and gathered management technique, in specific throughout a time when information from Voyager 1 showed that the spacecraft had actually certainly crossed into interstellar area.
“Nobody might wait to get to interstellar area, however we wished to get it right,” Dodd remembered. “We understood there would be individuals who disagreed. Ed desired to comprehend the complete story and the presumptions individuals were making. He did a great task listening to everyone and letting them take part in the discussion without anybody monopolizing.”
Stone has actually gotten many awards, consisting of the National Medal of Science (1991 ), the Magellanic Premium (1992 ), the Carl Sagan Memorial Award (1999 ), the Philip J. Klass Lifetime Achievement Award (2007 ), and the Howard Hughes Memorial Award (2014 ). In 2013, on the program “The Colbert Report,” late-night television host Stephen Colbert provided Stone with the NASA Distinguished Public Service Medal, the firm’s greatest honor for a nongovernment person. Stone belonged to the National Academy of Sciences.
Stone was predeceased by his other half, Alice, and is endured by his children Susan and Janet, son-in-law Tom, grandsons Michael and Ryan, and granddaughter-in-law Lauren. A funeral will be held at a later date. In the meantime, Stone’s household recommends those wanting to commemorate his life may “check out an unknown world of science, delight in an opera, trek with friends and family, share a stovetop pan of fresh popcorn, or experience along a brand-new path home.” In lieu of flowers, the household recommends contributions to Caltech’s Summer Season Undergraduate Research Fellowships (SURF) programthe Planetary Societyor the Los Angeles Opera
