NASA/Helen Arase Vargas The team was named in honor of Dr. Alvaro Salcedo, a robotics teacher and competitive robotics coach who had a significant impact on Kantsevoy and Bonner during high school. Dr. Salcedo played a crucial role in shaping their interests and aspirations in science, technology, engineering, and mathematics (STEM), inspiring them to pursue careers in these fields.
Kantsevoy, a computer science major at Georgia Institute of Technology, or Georgia Tech, led the team with three years of Kibo-RPC experience and a deep interest in robotics and space-based agriculture. Bonner, a second-year student at the University of Miami, is pursuing a triple major in computer science, artificial intelligence, and mathematics. Known for his quick problem-solving, he played a key role as a strategist and computer vision expert. Paschke, a first-time participant and computer science student at Georgia Tech, focused on intelligence systems and architecture, and brought fresh insights to the table. Ashkenazi, also studying computer science at Georgia Tech, specialized in computer vision and DevOps, adding depth to the team’s technical capabilities.
AstroBee Takes Flight
The 2024 competition tasked students with programming AstroBee, a free-flying robot aboard the station, to navigate a complex course while capturing images scattered across the orbital outpost. For Team Salcedo, the challenge reached its peak as their code was tested live on the space station.

Watching AstroBee in action aboard the space station offered a rare glimpse of the direct impact of their programming skills and added a layer of excitement that pushed them to fine-tune their approach.
Overcoming Challenges in Real Time
Navigating AstroBee through the orbital outpost presented a set of unique challenges. The team had to ensure the robot could identify and target images scattered throughout the station with precision while minimizing the time spent between locations.
The Kibo-RPC students watch in real time as the free-flying robot Astrobee performs maneuvers aboard the International Space Station, executing tasks based on their input to test its capabilities. NASA/Helen Arase Vargas Using quaternions for smooth rotation in 3D space, they fine-tuned AstroBee’s movements to adjust camera angles and capture images from difficult positions without succumbing to the limitations of gimbal lock. Multithreading allowed the robot to simultaneously process images and move to the next target, optimizing the use of time in the fast-paced environment.
The Power of Teamwork and Mentorship
Working across different locations and time zones, Team Salcedo established a structured communication system to ensure seamless collaboration. Understanding each team member’s workflow and adjusting expectations accordingly helped them maintain efficiency, even when setbacks occurred.

NASA/Helen Arase Vargas Mentorship was crucial to their success, with the team crediting several advisors and educators for their guidance. Kantsevoy acknowledged his first STEM mentor, Casey Kleiman, who sparked his passion for robotics in middle school.
The team expressed gratitude to their Johnson mentors, including NASA Program Specialist Jamie Semple, Education Coordinator Kaylie Mims, and International Space Station Research Portfolio Manager Jorge Sotomayer, for guiding them through the program’s processes and providing support throughout the competition.
They also thanked NASA’s Office of STEM Engagement for offering the opportunity to present their project to Johnson employees.
“The challenge mirrors how the NASA workforce collaborates to achieve success in a highly technical environment. Team Salcedo has increased their knowledge and learned skills that they most likely would not have acquired individually,” said Semple. “As with all of our student design challenges, we hope this experience encourages the team to continue their work and studies to hopefully return to NASA in the future as full-time employees.”
Pushing the Boundaries of Innovation
The Kibo-RPC allowed Team Salcedo to experiment with new techniques, such as Slicing Aided Hyperinference—an approach that divides images into smaller tiles for more detailed analysis. Although this method showed promise in detecting smaller objects, it proved too time-consuming under the competition’s time constraints, teaching the students valuable lessons about prioritizing efficiency in engineering.

The thrill of seeing their code in action on the orbital outpost was a reminder of the limitless possibilities in robotics and space exploration.
Inspiring the Next Generation
With participants from diverse backgrounds coming together to compete on a global platform, the Kibo-RPC continues to be a proving ground for future innovators.

As Team Salcedo looks ahead, they carry with them the skills, experiences, and inspiration needed to push the boundaries of human space exploration.
“With programs like Kibo-RPC, we are nurturing the next generation of explorers – the Artemis Generation,” said Sotomayer. “It’s not far-fetched to imagine that one of these students could eventually be walking on the Moon or Mars.”
The winners were announced virtually from Japan on Nov. 9, with Team Salcedo achieving sixth place.

On Sept. 9 and 10, scientists and engineers tested NASA’s LEMS (Lunar Environment Monitoring Station) instrument suite in a “sandbox” of simulated Moon regolith at the Florida Space Institute’s Exolith Lab at the University of Central Florida in Orlando.
Lunar regolith is a dusty, soil-like material that coats the Moon’s surface, and researchers wanted to observe how the material would interact with LEMS’s hardware, which is being developed to fly to the Moon with Artemis III astronauts in late 2026.
Designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, LEMS is one of three science payloads chosen for development for Artemis III, which will be the first mission to land astronauts on the lunar surface since 1972.
The LEMS instrument package can operate both day and night. It will carry two University of Arizona-built seismometers to the surface to perform long-term monitoring for moonquakes and meteorite impacts.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Data from one of the two CubeSats that comprise NASA’s PREFIRE mission was used to make this data visualization showing brightness temperature — the intensity of infrared emissions — over Greenland. Red represents more intense emissions; blue indicates lower intensities. The data was captured in July.
NASA’s Scientific Visualization Studio The PREFIRE mission will help develop a more detailed understanding of how much heat the Arctic and Antarctica radiate into space and how this influences global climate.
NASA’s newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experiment (PREFIRE) are key to better predicting how climate change will affect Earth’s ice, seas, and weather — information that will help humanity better prepare for a changing world.
One of PREFIRE’s two shoebox-size cube satellites, or CubeSats, launched on May 25 from New Zealand, followed by its twin on June 5. The first CubeSat started sending back science data on July 1. The second CubeSat began collecting science data on July 25, and the mission will release the data after an issue with the GPS system on this CubeSat is resolved.
The PREFIRE mission will help researchers gain a clearer understanding of when and where the Arctic and Antarctica emit far-infrared radiation (wavelengths greater than 15 micrometers) to space. This includes how atmospheric water vapor and clouds influence the amount of heat that escapes Earth. Since clouds and water vapor can trap far-infrared radiation near Earth’s surface, they can increase global temperatures as part of a process known as the greenhouse effect. This is where gases in Earth’s atmosphere — such as carbon dioxide, methane, and water vapor — act as insulators, preventing heat emitted by the planet from escaping to space.
“We are constantly looking for new ways to observe the planet and fill in critical gaps in our knowledge. With CubeSats like PREFIRE, we are doing both,” said Karen St. Germain, director of the Earth Science Division at NASA Headquarters in Washington. “The mission, part of our competitively-selected Earth Venture program, is a great example of the innovative science we can achieve through collaboration with university and industry partners.”
Earth absorbs much of the Sun’s energy in the tropics; weather and ocean currents transport that heat toward the Arctic and Antarctica, which receive much less sunlight. The polar environment — including ice, snow, and clouds — emits a lot of that heat into space, much of which is in the form of far-infrared radiation. But those emissions have never been systematically measured, which is where PREFIRE comes in.
“It’s so exciting to see the data coming in,” said Tristan L’Ecuyer, PREFIRE’s principal investigator and a climate scientist at the University of Wisconsin, Madison. “With the addition of the far-infrared measurements from PREFIRE, we’re seeing for the first time the full energy spectrum that Earth radiates into space, which is critical to understanding climate change.”
This visualization of PREFIRE data (above) shows brightness temperatures — or the intensity of radiation emitted from Earth at several wavelengths, including the far-infrared. Yellow and red indicate more intense emissions originating from Earth’s surface, while blue and green represent lower emission intensities coinciding with colder areas on the surface or in the atmosphere.
The visualization starts by showing data on mid-infrared emissions (wavelengths between 4 to 15 micrometers) taken in early July during several polar orbits by the first CubeSat to launch. It then zooms in on two passes over Greenland. The orbital tracks expand vertically to show how far-infrared emissions vary through the atmosphere. The visualization ends by focusing on an area where the two passes intersect, showing how the intensity of far-infrared emissions changed over the nine hours between these two orbits.
The two PREFIRE CubeSats are in asynchronous, near-polar orbits, which means they pass over the same spots in the Arctic and Antarctic within hours of each other, collecting the same kind of data. This gives researchers a time series of measurements that they can use to study relatively short-lived phenomena like ice sheet melting or cloud formation and how they affect far-infrared emissions over time.
More About PREFIRE
The PREFIRE mission was jointly developed by NASA and the University of Wisconsin-Madison. A division of Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory manages the mission for NASA’s Science Mission Directorate and provided the spectrometers. Blue Canyon Technologies built and now operates the CubeSats, and the University of Wisconsin-Madison is processing and analyzing the data collected by the instruments.
