If you design a new tool for use on Earth, it is easy to test and practice using that tool in its intended environment. But what if that tool is destined for lunar orbit or will be used by astronauts on the surface of the Moon?
NASA’s Simulation and Graphics Branch can help with that. Based at Johnson Space Center in Houston, the branch’s high-fidelity, real-time graphical simulations support in-depth engineering analyses and crew training, ensuring the safety, efficiency, and success of complex space endeavors before execution. The team manages multiple facilities that provide these simulations, including the Prototype Immersive Technologies (PIT) Lab, Virtual Reality Training Lab, and the Systems Engineering Simulator (SES).
Lee Bingham is an aerospace engineer on the simulation and graphics team. His work includes developing simulations and visualizations for the NASA Exploration Systems Simulations team and providing technical guidance on simulation and graphics integration for branch-managed facilities. He also leads the branch’s human-in-the-loop Test Sim and Graphics Team, the Digital Lunar Exploration Sites Unreal Simulation Tool (DUST), and the Lunar Surface Mixed-Reality with the Active Response Gravity Offload System (ARGOS) projects.

DUST has supported several human-in-the-loop studies for NASA. It has also been shared with external collaborators and made available to the public through the NASA Software Catalog.
Bingham has kept busy during his nearly nine years at Johnson and said learning to manage and balance support for multiple projects and customers was very challenging at first. “I would say ‘yes’ to pretty much anything anyone asked me to do and would end up burning myself out by working extra-long hours to meet milestones and deliverables,” he said. “It has been important to maintain a good work-life balance and avoid overcommitting myself while meeting demanding expectations.”

And be sure to recognize and acknowledge your coworkers and teammates when they go above and beyond or achieve something remarkable.”

For more than a decade, Tristan McKnight has been a driving force behind some of NASA’s most iconic events, orchestrating the behind-the-scenes magic that brings each historic moment to life while sharing the agency’s advancements with the public.
As a multimedia producer on the audiovisual team at Johnson Space Center in Houston, McKnight produces and directs live broadcasts and manages event planning, coordination, and execution. From overseeing resources, mitigating risks, and communicating with stakeholders, he ensures every detail aligns seamlessly.
Official portrait of Tristan McKnight.NASA/Josh Valcarcel McKnight has played an integral role in the audiovisual team’s coverage of major events including the Artemis II crew announcement, where NASA revealed the astronauts who will venture around the Moon and back, to Johnson’s 2023 Open House, which celebrated the agency’s 65th anniversary and the 25th anniversary of the International Space Station’s operations. These achievements highlight key milestones in human space exploration.
A standout achievement was contributing to the Dorothy Vaughan Center in Honor of the Women of Apollo naming ceremony, held on the eve of the 55th anniversary of the Apollo 11 Moon landing. The event honored the unsung heroes who made humanity’s first steps on the Moon possible.
The team’s dedication and passion are a testament to their commitment to sharing NASA’s legacy with the world.
“Not only have these events been impactful to Johnson, but they have also resonated across the entire agency,” McKnight said. “That is what I’m most proud of!”

McKnight recalled how the speaker transformed Johnson’s Teague Auditorium into a venue filled with drum kits, inspiring messages, and lighting displays. Each audience member, drumsticks in hand, participated in a lesson on teamwork and synchronization to create a metaphor for working in harmony toward a shared goal.
Like many high-achieving professionals. McKnight has faced moments of self-doubt. Then he realized that he is exactly where he is supposed to be. “As I settled into my role, I recognized that my contributions matter and simply being true to who I am adds value to the Johnson community,” he said.

One of McKnight’s most valuable lessons is recognizing that there is no one-size-fits-all solution, and each situation requires a thoughtful analysis.
McKnight understands the importance of the “check-and double-check,” a philosophy he considers crucial when working with technology. “Taking the extra time to do your due diligence, or even having someone else take a look, can make all the difference,” he said.
“The challenges I’ve faced helped me grow as a problem solver and taught me valuable lessons on resilience and adaptability in the workplace,” he said. McKnight approaches obstacles with a level head, focusing on effective solutions rather than dwelling on the problem.

NASA/Helen Arase Vargas As humanity looks to the stars, McKnight is energized about the future of exploration, particularly advancements in spacesuit and rocket technology that will enable us to travel farther, faster, and safer than ever before. His work, though grounded on Earth, helps create the inspiration that fuels these bold endeavors.
“My hope for the next generation is that they dive deeper into their curiosity—exploring not only the world around them but also the Moon, planets, and beyond,” he said. “I also hope they carry forward the spirit of resilience and a commitment to making the world a better place for all.”
