NASA For some people, a passion for space is something that might develop over time, but for Patrick Junen, the desire was there from the beginning. With a father and grandfather who both worked for NASA, space exploration is not just a dream; it remains a family legacy.
Now, as the stage assembly and structures subsystem manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the BOLE (Booster Obsolescence Life Extension) Program — an advanced solid rocket booster for NASA’s SLS (Space Launch System) heavy lift rocket — Junen is continuing that legacy.
“My grandfather worked on the Apollo & Space Shuttle Programs. Then my dad went on to work for the Space Shuttle and SLS Programs,” Junen says. “I guess you could say engineering is in my blood.”
In his role, he’s responsible for managing the Design, Development, Test, & Evaluation team for all unpressurized structural elements, such as the forward skirt, aft skirt, and the integration hardware that connects the boosters to the core stage. He also collaborates closely with NASA’s Exploration Ground Systems at Kennedy Space Center in Florida to coordinate any necessary modifications to ground facilities or the mobile launcher to support the new boosters.
Junen enjoys the technical challenges of his role and said he feels fortunate to be in a position of leadership — but it takes a team of talented individuals to build the next generation of boosters. As a former offensive lineman for the University of Mississippi, he knows firsthand the power of teamwork and the importance of effective communication in guiding a coordinated effort.
“I’ve always been drawn to team activities, and exploration is the ultimate team endeavor,” Junen says. “On the football field, it takes a strong team to be successful — and it’s really no different from what we’re doing as a team at NASA with our Northrop Grumman counterparts for the SLS rocket and Artemis missions.”
As a kid, Junen often accompanied his dad to Space Shuttle launches and was inspired by some of the talented engineers that developed Shuttle. Years later, he’s still seeing some of those same faces — but now they’re teammates, working together toward a greater mission.
“Growing up around Marshall Space Flight Center in Huntsville, Alabama, there was always this strong sense of family and dedication to the Misson. And that has always resonated with me,” Junen recalls.
This philosophy of connecting family to the mission is a tradition Junen now continues with his own children. One of his fondest NASA memories is watching the successful launch of Artemis I on Nov. 16, 2022. Although he couldn’t attend in person, Junen and his family made the most of the moment — watching the launch live beneath the Saturn V rocket at Huntsville’s U.S. Space & Rocket Center. With his dad beside him and his daughter on his shoulders, three generations stood beneath the rocket Junen’s grandfather helped build, as a new era of space exploration began.
In June, Junen witnessed the BOLE Demonstration Motor-1 perform a full-scale static test to demonstrate the ballistic performance for the evolved booster motor. This test isn’t just a technical milestone for Junen — it’s a continuation of a lifelong journey rooted in family and teamwork.
As NASA explores the Moon and prepares for the journey to Mars through Artemis, Junen is helping shape the next chapter of human spaceflight. And just like the generations before him, he’s not only building rockets — he’s building a legacy.

Communicating in space usually relies on radio waves, but NASA is exploring laser, or optical, communications, which can send data 10 to 100 times faster to the ground. Instead of radio signals, these systems use infrared light to transmit high-definition video, picture, voice, and science data across vast distances in less time. NASA has proven laser communications during previous technology demonstrations, but Artemis II will be the first crewed mission to attempt using lasers to transmit data from deep space.
To support this effort, researchers working on the agency’s Real Time Optical Receiver (RealTOR) project have developed a cost-effective laser transceiver using commercial-off-the-shelf parts. Earlier this year, NASA Glenn engineers built and tested a replica of the system at the center’s Aerospace Communications Facility, and they are now working with ANU to build a system with the same hardware models to prepare for the university’s Artemis II laser communications demo.
“Australia’s upcoming lunar experiment could showcase the capability, affordability, and reproducibility of the deep space receiver engineered by Glenn,” said Jennifer Downey, co-principal investigator for the RealTOR project at NASA Glenn. “It’s an important step in proving the feasibility of using commercial parts to develop accessible technologies for sustainable exploration beyond Earth.”
During Artemis II, which is scheduled for early 2026, NASA will fly an optical communications system aboard the Orion spacecraft, which will test using lasers to send data across the cosmos. During the mission, NASA will attempt to transmit recorded 4K ultra-high-definition video, flight procedures, pictures, science data, and voice communications from the Moon to Earth.

This ground station will serve as a test location for the new transceiver design and will not be one of the mission’s primary ground stations. If the test is successful, it will prove that commercial parts can be used to build affordable, scalable space communication systems for future missions to the Moon, Mars, and beyond.
“Engaging with The Australian National University to expand commercial laser communications offerings across the world will further demonstrate how this advanced satellite communications capability is ready to support the agency’s networks and missions as we set our sights on deep space exploration,” said Marie Piasecki, technology portfolio manager for NASA’s Space Communications and Navigation (SCaN) Program.
As NASA continues to investigate the feasibility of using commercial parts to engineer ground stations, Glenn researchers will continue to provide critical support in preparation for Australia’s demonstration.
Strong global partnerships advance technology breakthroughs and are instrumental as NASA expands humanity’s reach from the Moon to Mars, while fueling innovations that improve life on Earth. Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

These include the LCOT (Low-Cost Optical Terminal) project, the Laser Communications Relay Demonstration, and more. NASA Glenn manages the project under the direction of agency’s SCaN Program at NASA Headquarters in Washington.
The Australian National University’s demonstration is supported by the Australian Space Agency Moon to Mars Demonstrator Mission Grant program, which has facilitated operational capability for the Australian Deep Space Optical Ground Station Network.
