From the Mission Control Center to community celebrations, Kenneth Attocknie blends safety expertise with a commitment to cultural connection.
For the past 25 years at NASA, Attocknie has dedicated his career to safeguarding the International Space Station and supporting real-time mission operations at Johnson Space Center in Houston.
As a principal safety engineer in the Safety and Mission Assurance Directorate, Attocknie ensures the safe operation of the space station’s environmental control and life support system. This system is vital for maintaining the life-sustaining environment aboard the orbiting laboratory— a critical foundation for similar systems planned for future Artemis missions.
Official portrait of Kenneth Attocknie.NASA/Bill Stafford As a contractor with SAIC, Attocknie has served as a flight controller, astronaut crew office engineer, and astronaut crew instructor. He joined NASA just as the first two modules of the space station, Zarya and Unity, connected in space on Dec. 6, 1998.
“I’ve supported the space station ever since and have been blessed to witness the remarkable progression of this amazing orbiting experiment,” he said. “I feel I have found a way to contribute positively to NASA’s mission: to improve life for all people on our planet.”
He also contributed to closing out the Space Shuttle Program and worked in system safety for the Constellation program.
As part of SAIC’s Employee Resource Group, Attocknie supports the Mathematics, Engineering, Science Achievement project, which uses project-based learning to inspire high school students from underrepresented communities to pursue careers in science, technology, engineering, and mathematics. He continues to advocate for Native Americans as a member of the American Indian Science and Engineering Society, helping NASA engage with college students across Indian Country.

The spacecraft is scheduled to autonomously dock at approximately 10:15 a.m. to the forward port of the space station’s Harmony module.
The resupply mission will support dozens of research experiments conducted during Expedition 72. In addition to food, supplies, and equipment for the crew, Dragon will deliver several new experiments, including the Coronal Diagnostic Experiment, to examine solar wind and how it forms. Dragon also delivers Antarctic moss to observe the combined effects of cosmic radiation and microgravity on plants. Other investigations aboard include a device to test cold welding of metals in microgravity and an investigation that studies how space impacts different materials.
These are just a sample of the hundreds of investigations conducted aboard the orbiting laboratory in the areas of biology and biotechnology, physical sciences, and Earth and space science. Such research benefits humanity and lays the groundwork for future human exploration through the agency’s Artemis campaign, which will send astronauts to the Moon to prepare for future expeditions to Mars.
The Dragon spacecraft is scheduled to remain at the space station until December when it will depart the orbiting laboratory and return to Earth with research and cargo, splashing down off the coast of Florida.

This archival photo shows engineers working on NASA’s Voyager 2 spacecraft on March 23, 1977. NASA/JPL-Caltech NASA’s Voyager mission launched in the 1970s. Today, it’s making history as it conducts new science. But how are two spacecraft from the ’70s not just surviving, but thriving farther out in space than any other spacecraft has been before?
A Little Mission Background
Voyager is a NASA mission made up of two different spacecraft, Voyager 1 and 2, which launched to space on Sept. 5, 1977, and Aug. 20, 1977, respectively. In the decades following launch, the pair took a grand tour of our solar system, studying Jupiter, Saturn, Uranus, and Neptune — one of NASA’s earliest efforts to explore the secrets of the universe. These twin probes later became the first spacecraft to operate in interstellar space — space outside the heliosphere, the bubble of solar wind and magnetic fields emanating from the Sun. Voyager 1 was the first to enter interstellar space in 2012, followed by Voyager 2 in 2018.
Today, Voyager continues not just because it can, but because it still has work to do studying interstellar space, the heliosphere, and how the two interact. “We wouldn’t be doing Voyager if it wasn’t taking science data,” said Suzanne Dodd, the mission’s current project manager and the director for the Interplanetary Network at NASA’s Jet Propulsion Laboratory.
But across billions of miles and decades of groundbreaking scientific exploration, this trailblazing interstellar journey has not been without its trials. So, what’s the Voyager secret to success?
In short: preparation and creativity.
As NASA’s two Voyager spacecraft travel out into deep space, they carry a small American flag and a Golden Record packed with pictures and sounds — mementos of our home planet. This picture shows John Casani, Voyager project manager in 1977, holding a small Dacron flag that was folded and sewed into the thermal blankets of the Voyager spacecraft before they launched 36 years ago. Below him lie the Golden Record (left) and its cover (right). In the background stands Voyager 2 before it headed to the launch pad. The picture was taken at Cape Canaveral, Fla., on Aug. 4, 1977. NASA/JPL-Caltech We Designed Them Not to Fail
According to John Casani, Voyager project manager from 1975 to launch in 1977, “we didn’t design them to last 30 years or 40 years, we designed them not to fail.”
One key driver of the mission’s longevity is redundancy. Voyager’s components weren’t just engineered with care, they were also made in duplicate.
According to Dodd, Voyager “was designed with nearly everything redundant. Having two spacecraft — right there is a redundancy.”
“We didn’t design them to last 30 years or 40 years, we designed them not to fail.”

A Cutting-Edge Power Source
The twin Voyager spacecraft can also credit their longevity to their long-lasting power source.
Each spacecraft is equipped with three radioisotope thermoelectric generators. These nuclear “batteries” were developed originally by the U.S. Department of Energy as part of the Atoms for Peace program enacted by President Eisenhower in 1955. Compared to other power options at the time — like solar power, which doesn’t have the reach to work beyond Jupiter — these generators have allowed Voyager to go much farther into space.
Each of NASA’s Voyager probes are equipped with three radioisotope thermoelectric generators (RTGs), including the one shown here at NASA’s Kennedy Space Center in Florida. The RTGs provide power for the spacecraft by converting the heat generated by the decay of plutonium-238 into electricity. Launched in 1977, the Voyager mission is managed for NASA by the agency’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California.
NASA/JPL-Caltech Voyager’s generators continue to take the mission farther than any before, but they also continue to generate less power each year, with instruments needing to be shut off over time to conserve power.
Creative Solutions
As a mission that has operated at the farthest edges of the heliosphere and beyond, Voyager has endured its fair share of challenges. With the spacecraft now in interstellar space running on software and hardware from the 1970s, Voyager’s problems require creative solutions.
Retired mission personnel who worked on Voyager in its earliest days have even come back out of retirement to collaborate with new mission personnel to not just fix big problems but to pass on important mission know-how to the next generation of scientists and engineers.
“From where I sit as a project manager, it’s really very exciting to see young engineers be excited to work on Voyager. To take on the challenges of an old mission and to work side by side with some of the masters, the people that built the spacecraft,” Dodd said. “They want to learn from each other.”
After receiving data about the health and status of Voyager 1 for the first time in five months, members of the Voyager flight team celebrate in a conference room at NASA’s Jet Propulsion Laboratory on April 20. Credit: NASA/JPL-Caltech NASA/JPL-Caltech Within just the last couple of years, Voyager has tested the mission team’s creativity with a number of complex issues. Most recently, the thrusters on Voyager 1’s thrusters, which control the spacecraft’s orientation and direction, became clogged. The thrusters allow the spacecraft to point their antennae and are critical to maintaining communications with Earth. Through careful coordination, the mission team was able to remotely switch the spacecraft to a different set of thrusters.
These kinds of repairs are extra challenging as a radio signal takes about 22 ½ hours to reach Voyager 1 from Earth and another 22 ½ hours to return. Signals to and from Voyager 2 take about 19 hours each way.
Voyager’s Interstellar Future
This brief peek behind the curtain highlights some of Voyager’s history and its secrets to success.
The Voyager probes may continue to operate into the late 2020s. As time goes on, continued operations will become more challenging as the mission’s power diminishes by 4 watts every year, and the two spacecraft will cool down as this power decreases. Additionally, unexpected anomalies could impact the mission’s functionality and longevity as they grow older.
As the mission presses on, the Voyager team grows this legacy of creative problem solving and collaboration while these twin interstellar travelers continue to expand our understanding of the vast and mysterious cosmos we inhabit.
