Edward Stone is retiring after 50 years as Venture Scientist for the Voyager mission. The dual spacecraft revolutionized our understanding of our Photo voltaic System, and Stone was alongside for the journey each step of the way in which. Each spacecraft are nonetheless going, travelling deeper into interplanetary area, and nonetheless sending knowledge house.
However after a protracted and rewarding profession filled with achievements and recognition, Stone is transferring on.
When the Voyager spacecraft launched in 1977, our understanding of the Photo voltaic System was in its infancy. However Voyager 1 and a pair of modified that. The mission set off a cascade of discoveries that also resonates as we speak.

The mission illuminated our understanding of the outer Photo voltaic System. Amongst different issues, the spacecraft noticed volcanic exercise on Jupiter’s moon Io, discovered erupting plumes on Saturn’s moon Titan, and found 16 new moons.
Voyager gave us close-up color photos of the outer planets that introduced them to life. Actually, the pair of them took over 33,000 photographs of simply Jupiter and its moons.
However the mission’s most well-known picture is of distant Earth. It’s referred to as “The Pale Blue Dot,” and it’s the final picture Voyager 1 took earlier than its cameras have been turned off ceaselessly. It was Carl Sagan’s concept to level the spacecraft again towards Earth and take the image.
Ed Stone was the Voyager Venture Scientist via all of this, and now he’s introduced his retirement. Over time, Stone was an eloquent spokesperson for the Voyager mission.
“In exploring the 4 outer planets, Voyager has already had an epic journey of discovery,” Stone stated in 1991. “Even so, their journey is lower than half over, with extra discoveries awaiting the primary contact with interstellar area,” Stone stated. “The Voyagers revealed how restricted our imaginations actually have been about our photo voltaic system, and I count on that as they proceed towards interstellar area, they’ll once more shock us with unimagined discoveries of this never-before-visited place which awaits us past our planetary neighbourhood.”
“After I look again, I understand how little we really knew concerning the photo voltaic system earlier than Voyager,” Stone stated in 2010. “We found issues we didn’t know have been there to be found, time after time.”
Stone was a busy man and was concerned in lots of different missions apart from Voyager. Throughout his time period as director of JPL, he was accountable for quite a lot of missions and devices, together with Magellan, Galileo, Ulysses, TOPEX/Poseidon, Mars Observer, Hubble Huge Discipline/Planetary Digital camera, Shuttle Imaging Radar, NASA Scatterometer, Mars International Surveyor, Mars Pathfinder/Sojourner, Cassini/Huygens, Deep Area 1, QuickSCAT, ACRIMSAT, Stardust, Mars Local weather Orbiter, Mars Polar Lander, Shuttle Radar Topography Mission, Mars Odyssey, Genesis and Jason l.
Stone obtained accolades for his contribution to science and humanity. In 1986, he gained the Excellent Management Medal together with different members of the Voyager crew. In 2014 he obtained a lifetime achievement award from the American Astronautical Society. He even went on the Stephen Colbert present in 2013 to speak about Voyager, and Colbert stunned him with the NASA Distinguished Public Service Medal.
“I used to be on the Colbert Report to speak about what I consider as humankind’s biggest—and definitely most in depth—journey of exploration, and I definitely didn’t count on the host at hand me an award,” stated Stone. “That shock on my face was actual.”
Stone could also be retiring, however Voyager isn’t. Mission operators are dealing with the spacecraft very rigorously, although, and preserving energy by shutting particular person methods down. However each Voyager 1 and a pair of are nonetheless transmitting knowledge from their journey into interstellar area.
“The beauty of the Voyager journey is not only that it’s 40 years lengthy, however the truth is, it’s nonetheless discovering new issues as a result of it’s going the place nothing has been earlier than,” Stone stated in 2017.
Voyager 1 and a pair of will outlive Stone, which is sort of unhappy and exquisite on the similar time. Actually, the spacecraft would possibly outlive humanity. They’ll run out of energy and cease gathering and transmitting knowledge, however they’ll preserve going, carrying a present within the occasion of an unlikely encounter with one other civilization.
Hope rides shotgun on missions like Voyager. Alongside all of the science targets is the concept it’s all value it. That humanity has a future. And 1977 was a special world in comparison with as we speak.
The West was locked into the Chilly Conflict with the USSR. Their arsenals of nuclear weapons grew bigger and bigger, they usually devised extra technologically ingenious methods to ship them to every others’ cities. Folks have been fearful about nuclear accidents and poisonous waste, and there have been gloomy predictions concerning the surroundings and human over-population.
On the flip facet, Star Wars was launched in 1977, private house computer systems have been accessible on the market, smallpox was eradicated, and the primary check flight of the Area Shuttle happened.
So much has occurred for the reason that Voyager spacecraft have been launched. Little question Stone is reflective about how the world has modified since 1977. For Stone, it’s been a outstanding journey.
“It has been an honour and a pleasure to function the Voyager undertaking scientist for 50 years,” Stone stated. “The spacecraft have succeeded past expectation, and I’ve cherished the chance to work with so many proficient and devoted folks on this mission. It has been a outstanding journey, and I’m grateful to everybody world wide who has adopted Voyager and joined us on this journey.”
From all of us who’re hopeful about humanity, thanks Ed.
