NASA researchers Guan Yang, Jeff Chen, and their team received the 2024 Innovator of The Year Award at the agency’s Goddard Space Flight Center in Greenbelt, Maryland, for their exemplary work on a lidar system enhanced with artificial intelligence and other technologies.
Engineer Jeffrey Chen tests a lidar prototype on the roof of Building 33 at NASA’s Goddard Space Flight Center in Greenbelt, Md. Chen and his team earned the center’s 2024 Innovator of the Year award for their work on CASALS, a lidar system enhanced with artificial intelligence and other technologies.NASA Like a laser-based version of sonar, lidar and its use in space exploration is not new. But the lidar system Yang and Chen’s team have developed — formally the Concurrent Artificially-intelligent Spectrometry and Adaptive Lidar System (CASALS) — can produce higher resolution data within a smaller space, significantly increasing efficiency compared to current models.
The true revolution in CASALS is a unique combination of related technologies, such as highly efficient laser and receiver designs, wavelength-based, non-mechanical beam steering, multispectral imaging, and the incorporation of artificial intelligence to allow the instrument to make its own decisions while in orbit, instead of waiting for direction from human controllers on the ground.
“Existing 3D-imaging lidars struggle to provide the 2-inch resolution needed by guidance, navigation and control technologies to ensure precise and safe landings essential for future robotic and human exploration missions,” team engineer Jeffrey Chen said in an earlier interview. “Such a system requires 3D hazard-detection lidar and a navigation doppler lidar, and no existing system can perform both functions.”
The CASALS lidar is being developed to study land and ice topography, coastline changes, and other Earth science topics. Future applications in solar system science beyond our planet are already in the works, including space navigation improvements and high-resolution lunar mapping for NASA’s Artemis campaign to return astronauts to the Moon.
An effective and compact lidar system like CASALS could also map rocky planets like Venus or Mars.
NASA leveraged contributions from external Small Business Innovation Research companies such as Axsun Technologies, Freedom Photonics, and Left Hand for laser and optical technology to help make CASALS a reality.
The Internal Research and Development (IRAD) Innovator of The Year award is presented by Goddard’s Office of the Chief Technologist to a person or team within the program with a notable contribution to cutting-edge technology. The CASALS team was presented their award at a technology poster session on Nov. 6, 2024, at NASA Goddard.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The American Institute of Aeronautics and Astronautics (AIAA) has named two distinguished engineers at NASA’s Glenn Research Center in Cleveland AIAA Associate Fellows.
The grade of Associate Fellow recognizes individuals who have accomplished or overseen important engineering or scientific work, done original work of outstanding merit, or have otherwise made outstanding contributions to the arts, sciences, or technology of aeronautics or astronautics. To be selected as an Associate Fellow, an individual must be an AIAA Senior Member in good standing, with at least 12 years of professional experience, and be recommended by three AIAA members.
L. Danielle KochCredit: NASA L. Danielle Koch, aerospace engineer, performs research and educational outreach at NASA Glenn. Her 34-year career at NASA has been dedicated to conducting research for safer, cleaner, and quieter aircraft engines; high-performance ventilation systems for spacecraft; and bio-inspired broadband acoustic absorbers. She has authored over 50 technical publications and has been granted three patents. Koch has been recognized for excellence in engineering and educational outreach with many awards, most recently named as one of the 2024 Women of Distinction by the Girl Scouts of Northeast Ohio.
Dr. Sam LeeCredit: NASA Dr. Sam Lee, a research engineer supporting the Aircraft Icing Branch, conducts research in NASA Glenn’s Icing Research Tunnel to study how ice builds up, or accretes, on aircraft surfaces. The results from the experiments are used to understand the physics of how ice accretes on aircraft during flight and to provide the validation data to develop computational tools to predict ice accretion. He also performs research on the effects of ice accretion on aircraft performance in aerodynamic wind tunnels. Lee has authored 17 conference papers and journal papers. He has contributed to the development of many future engineers and scientists as a mentor for NASA’s Explorer Scouts program and various college internship programs. Lee has been part of the Aircraft Icing Branch since 2002.
AIAA will formally honor and induct the class at the AIAA Associate Fellows Induction Ceremony and Dinner on Jan. 8, 2025, during the 2025 AIAA SciTech Forum in Orlando.

NASA SkillBridge Veterans touring Johnson Space Center’s Neutral Buoyancy Laboratory.Credit: NASA NASA is one of America’s Best Employers for Veterans, according to Forbes and Statista. Statista surveyed more than 24,000 military veterans – having served in the United States Armed Forces – working for companies with a minimum of 1,000 employees. Veterans were asked to share opinions about their employer on factors such as working conditions, salary and pay, and topics of interest to the veteran community.
This is the fourth consecutive year NASA has earned this recognition.
“NASA has a long history of collaboration and commitment to the military community,” said Deborah Sweet, NASA Veterans Employment Program Manager. “In addition to the many military members who have been part of our Astronaut program, many of our civil servants are Veterans who chose to continue serving by supporting NASA’s mission after they hung up the uniform.”
Across the agency, veterans deliver subject matter expertise, years of on-the-job training, and advanced skills in everything from information technology to transportation logistics and from supply-chain management to public relations.
NASA continues to increase efforts to bring veterans into its ranks. The agency recently expanded its SkillBridge Fellowship Program which provides transitioning members a chance to gain valuable work experience while learning about NASA.
Veterans who served on active duty and separated under honorable conditions may also be eligible for special hiring authorities such as veterans’ preference, as well as other veteran specific hiring options when applying for full time roles at NASA.
