Before astronauts venture around the Moon on Artemis II, the agency’s first crewed mission to the Moon since Apollo, Mark Cavanaugh is helping make sure the Orion spacecraft is safe and space-ready for the journey ahead.  

As an Orion integration lead at NASA’s Johnson Space Center in Houston, he ensures the spacecraft’s critical systems— in both the U.S.-built crew module and European-built service module—come together safely and seamlessly.

With nearly a decade of experience at NASA, Cavanaugh currently works within the Orion Crew and Service Module Office at Johnson. He oversees the technical integration of the European Service Module, which provides power, propulsion, and life support to Orion during Artemis missions to the Moon. His work includes aligning and verifying essential systems to keeping the crew alive, including oxygen, nitrogen, water storage, temperature regulation, and spacecraft structures. 

In addition to his integration work, Cavanaugh is an Orion Mission Evaluation Room (MER) manager. The MER is the engineering nerve center during Artemis flights, responsible for real-time monitoring of the Orion spacecraft and real-time decision-making. From prelaunch to splashdown, Cavanaugh will lead a team of engineers who track vehicle health and status, troubleshoot anomalies, and communicate directly with the flight director to ensure the mission remains safe and on track.

Cavanaugh’s passion for space exploration began early. “I’ve wanted to be an aerospace engineer since I was six years old,” he said. “My uncle, who is also an aerospace engineer, used to take me to wind tunnel tests and flight museums as a kid.” 

That passion only deepened after a fifth-grade trip from Philadelphia to Houston with his grandfather. “My dream of working at NASA Johnson started when I visited the center for the first time,” he said. “Going from being a fifth grader riding the tram on the tour to contributing to the great work done at Johnson has been truly incredible.” 

Turning that childhood dream into reality did not come with a straight path. Cavanaugh graduated from Pennsylvania State University in 2011, the same year NASA’s Space Shuttle Program ended. With jobs in the space industry in short supply, he took a position with Boeing in Houston, working on the International Space Station’s Passive Thermal Control System. He later supported thermal teams for the Artemis Moon rocket called the Space Launch System, and the Starliner spacecraft that flew astronauts Butch Wilmore and Suni Williams during their Boeing Crew Flight Test mission, before a mentor flagged a NASA job posting that turned out to be the perfect fit. 

He joined NASA as the deputy system manager for Orion’s Passive Thermal Control System, eventually stepping into his current leadership role on the broader Orion integration team. “I’ve been very lucky to work with some of the best and most supportive teammates you can imagine,” he said.

Cavanaugh says collaboration and empathy were key to solving challenges along the way. “I’ve learned to look at things from the other person’s perspective,” he said. “We’re all working toward the same incredible goal, even if we don’t always agree. That mindset helps keep things constructive and prevents misunderstandings.” 

He also emphasizes the importance of creative problem-solving. “For me, overcoming technical challenges comes down to seeking different perspectives, questioning assumptions, and not being afraid to try something new—even if it sounds a little ridiculous at first.”

Outside of work, Cavanaugh fuels his love of speed and precision by riding one of his three motorcycles. He has even taken laps at the Circuit of the Americas track in Austin, Texas.  

When he is not on the track or in the control room, Cavanaugh gives back through student outreach. “The thing I always stress when I talk to students is that nothing is impossible,” he said. “I never thought I’d get to work in the space industry, let alone at NASA. But I stayed open to opportunities—even the ones that didn’t match what I originally imagined for myself.”

This summer, a team of robots explored a simulated martian landscape in Germany, remotely guided by an astronaut aboard the International Space Station. This marked the fourth and final session of the Surface Avatar experiment, a collaboration between ESA and the German Aerospace Center (DLR) to develop how astronauts can control robotic teams to perform complex tasks on the Moon and Mars.

The session introduced new levels of autonomy and complexity. NASA astronaut Jonny Kim operated two robots – ESA’s four-legged Spot and DLR’s humanoid Rollin’ Justin – to retrieve scattered sample containers and deliver them to a lander. Spot navigated the terrain autonomously, while Justin was guided through a mix of direct control and pre-set commands. This setup allowed Jonny to delegate tasks and focus on higher-level decisions, building on other sessions where robots required full teleoperation.

In a second scenario, ESA’s Interact rover transported DLR’s robot dog Bert to a cave entrance. After removing a boulder, Jonny deployed Bert, which then simulated a malfunction in one of its legs. Jonny had to retrain Bert’s walking algorithm in real time before it continued into the cave and detected signs of martian ice. This tested how operators respond to unexpected challenges and adapt robotic systems on the fly.

The robots are controlled from the International Space Station using a custom-built interface developed by ESA and DLR, combining a joystick and a haptic-feedback device. The interface allows switching between first-person view for immersive teleoperation and a top-down map for broader mission oversight. This flexibility lets the astronaut manage multiple robots efficiently, balancing direct control with strategic delegation.

Over four sessions, the Surface Avatar team has refined its approach to human-robot interaction, improving both teleoperation and task delegation to autonomous systems. The experiment has also helped to identify which tasks astronauts prefer to control directly and which can be safely handed over to robotic systems, offering valuable insight for future mission planning.

But wait, before you build that moon casino we need to talk about a couple things. One, you really have to figure out how the roulette wheel is going to work in a low gravity environment. Second, we’re going to need you to keep the noise down.

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which also requires more powerful equipment, and positioning uncertainty that can affect the outcomes of measurements, especially in the outer reaches of the solar system. However, they can also be useful for a specific type of measurement called interferometry, where two systems a far distance apart can provide accurate location measurements to a third system - the same principle that GPS uses. A new paper looks at potentially using the same technique to track deep space probes rather than cars on a freeway and finds that, while it is around the same accuracy level, it is able to provide that same location data for more than double the amount of time.

How can artificial intelligence (AI) be used to locate lunar pits and skylights, which are surface depressions and openings, respectively, that serve as entrances to lava caves and lava tubes? This is what a recent study published in Icarus hopes to address as an international team of researchers investigated using machine learning algorithms to more efficiently identify pits and skylights on lunar volcanic regions (lunar maria) of the Moon. This study has the potential to help researchers develop new methods in identifying key surface features on planetary bodies that could aid in both robotic and human exploration.

New research on the samples collected by China's Chang'e-5 mission is revolutionizing our understanding of how the Moon cooled. A team led by Stephen M. Elardo, an Assistant Professor from the University of Florida, found that lava on the near side of the Moon likely came from a much shallower depth than previously thought, contradicting previous theories on how the Moon formed and evolved.
