On Sept. 20, 2024, four students experienced the wonder of space exploration at NASA’s Johnson Space Center in Houston, taking part in an international competition that brought their work to life aboard the International Space Station.
Now in its fifth year, the Kibo Robot Programming Challenge (Kibo-RPC) continues to push the boundaries of robotics, bringing together the world’s brightest young minds for a real-world test of programming, problem-solving, and innovation.
The Kibo Robot Programming Challenge (Kibo-RPC) students tour the Gateway Habitation and Logistics Outpost module at NASA’s Johnson Space Center in Houston.NASA/Helen Arase Vargas The stakes reached new heights in this year’s competition, with 661 teams totaling 2,788 students from 35 countries and regions competing to program robots aboard the orbiting laboratory. Organized by the Japan Aerospace Exploration Agency in collaboration with the United Nations Office for Outer Space Affairs, the challenge provided a unique platform for students to test their skills on a global stage.
Meet Team Salcedo
Representing the U.S., Team Salcedo is composed of four talented students: Aaron Kantsevoy, Gabriel Ashkenazi, Justin Bonner, and Lucas Paschke. Each member brought a unique skill set and perspective, contributing to the team’s well-rounded approach to the challenge.
From left to right are Kibo-RPC students Gabriel Ashkenazi, Lucas Paschke, Aaron Kantsevoy, and Justin Bonner. 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.
Team Salcedo tour the Space Vehicle Mockup Facility with their NASA mentors (from top left to right) Education Coordinator Kaylie Mims, International Space Station Research Portfolio Manager Jorge Sotomayer, and Kibo-RPC Activity Manager Jamie Semple. 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.

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Electra. The team’s project focuses on electric propulsion, integrated aircraft technologies, and vehicle design.Electra Picture yourself at an airport a few decades from now. What does your airliner look like? It’s more efficient, with lower emissions than today’s aircraft – what kinds of designs or technology make that possible? NASA is working to answer those questions by commissioning five new design studies looking to push the boundaries of possibility for sustainable aircraft.
Through NASA’s Advanced Aircraft Concepts for Environmental Sustainability (AACES) 2050 initiative, the agency asked industry and academia to come up with studies looking at aircraft concepts, key technologies, and designs that could offer the transformative solutions needed to secure commercial aviation’s sustainable future by 2050. NASA issued five awards, worth a total of $11.5 million, to four companies and one university. These new NASA-funded studies will help the agency identify and select promising aircraft concepts and technologies for further investigations.
Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Georgia Institute of Technology. The team’s project focuses on exploring scenarios and technologies based on an aircraft concept the institute has developed, known as ATH2ENA.Georgia Institute of Technology “Through initiatives like AACES, NASA is positioned to harness a broad set of perspectives about how to further increase aircraft efficiency, reduce aviation’s environmental impact and enhance U.S. technological competitiveness in the 2040s, 2050s, and beyond,” said Bob Pearce, NASA associate administrator for the Aeronautics Research Mission Directorate. “As a leader in U.S. sustainable aviation research and development, these awards are one example of how we bring together the best ideas and most innovative concepts from the private sector, academia, research agencies, and other stakeholders to pioneer the future of aviation.”
For decades, NASA has connected government agencies, industry, and academia to develop sustainable aviation technologies. In 2021, NASA launched its Sustainable Flight National Partnership, focused on technologies that could be incorporated into aircraft by the 2030s. The partnership’s research and development led to current NASA work including the experimental X-66 Sustainable Flight Demonstrator aircraft, its Electrified Powertrain Flight Demonstration project, and the development of more efficient engine cores and processes for the rapid manufacturing of lightweight composite materials.

The kinds of partnerships NASA develops through SFNP and AACES are critical for the agency to support the U.S. goal of net-zero aviation emissions by 2050 and to help put aviation on a path toward energy-resilience.
“The AACES 2050 solicitation drew significant interest from the aviation community and as a result the award process was highly competitive,” said Nateri Madavan, director for NASA’s Advanced Air Vehicles Program. “The proposals selected come from a diverse set of organizations that will provide exciting and wide-ranging explorations of the scenarios, technologies, and aircraft concepts that will advance aviation towards its transformative sustainability goals.”

NASA expects the awardees to complete their studies by mid-2026. The new awardee institutions are:
Aurora Flight Sciences, a Boeing Company, whose team will perform a comprehensive, “open-aperture” exploration of technologies and aircraft concepts for the 2050 timeframe. This will include examining new alternative aviation fuels, propulsion systems, aerodynamic technologies, and aircraft configurations along with other technology areas that arise throughout the study. The Electra-led team will explore extending Electra’s novel distributed electric propulsion and its unique aerodynamic design capabilities to develop innovative wing and fuselage integrations that deliver sustainable aviation focused on enabling community-friendly emission reduction, noise reduction, and improved air travel access. The company’s existing small aircraft prototype has been flying for over a year, demonstrating Electra’s technology that aims to transform air travel with reduced environmental impact and improved operational efficiency. Georgia Institute of Technology will perform a comprehensive exploration of sustainability technologies, including alternative fuels, propulsion systems, and aircraft configurations. The institute’s team will then explore new aircraft concepts incorporating the selected technologies with their Advanced Technology Hydrogen Electric Novel Aircraft (ATH2ENA) as a starting point. JetZero will explore technologies that enable cryogenic, liquid hydrogen to be used as a fuel for commercial aviation to reduce greenhouse gas emissions. These technologies will be evaluated on both tube-and wing and JetZero’s blended wing body – an airplane shape that provides more options for larger hydrogen fuel tanks within the aircraft. Pratt and Whitney a division of RTX Corporation, will explore a broad suite of commercial aviation propulsion technologies targeting thermal and propulsive efficiency improvements to reduce fuel consumption and greenhouse gas emissions. The Pratt & Whitney team will then down-select high-priority and alternative propulsion concepts for potential integration studies with various airframe concepts for aircraft in 2050 and beyond.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The NISAR mission will help researchers get a better understanding of how Earth’s surface changes over time, including in the lead-up to volcanic eruptions like the one pictured, at Mount Redoubt in southern Alaska in April 2009.R.G. McGimsey/AVO/USGS Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure.
We don’t always notice it, but much of Earth’s surface is in constant motion. Scientists have used satellites and ground-based instruments to track land movement associated with volcanoes, earthquakes, landslides, and other phenomena. But a new satellite from NASA and the Indian Space Research Organisation (ISRO) aims to improve what we know and, potentially, help us prepare for and recover from natural and human-caused disasters.
The NISAR (NASA-ISRO Synthetic Aperture Radar) mission will measure the motion of nearly all of the planet’s land and ice-covered surfaces twice every 12 days. The pace of NISAR’s data collection will give researchers a fuller picture of how Earth’s surface changes over time. “This kind of regular observation allows us to look at how Earth’s surface moves across nearly the entire planet,” said Cathleen Jones, NISAR applications lead at NASA’s Jet Propulsion Laboratory in Southern California.
Together with complementary measurements from other satellites and instruments, NISAR’s data will provide a more complete picture of how Earth’s surface moves horizontally and vertically. The information will be crucial to better understanding everything from the mechanics of Earth’s crust to which parts of the world are prone to earthquakes and volcanic eruptions. It could even help resolve whether sections of a levee are damaged or if a hillside is starting to move in a landslide.
The NISAR mission will measure the motion of Earth’s surface — data that can be used to monitor critical infrastructure such as airport runways, dams, and levees. NASA/JPL-Caltech What Lies Beneath
Targeting an early 2025 launch from India, the mission will be able to detect surface motions down to fractions of an inch. In addition to monitoring changes to Earth’s surface, the satellite will be able to track the motion of ice sheets, glaciers, and sea ice, and map changes to vegetation.
The source of that remarkable detail is a pair of radar instruments that operate at long wavelengths: an L-band system built by JPL and an S-band system built by ISRO. The NISAR satellite is the first to carry both. Each instrument can collect measurements day and night and see through clouds that can obstruct the view of optical instruments. The L-band instrument will also be able to penetrate dense vegetation to measure ground motion. This capability will be especially useful in areas surrounding volcanoes or faults that are obscured by vegetation.
“The NISAR satellite won’t tell us when earthquakes will happen. Instead, it will help us better understand which areas of the world are most susceptible to significant earthquakes,” said Mark Simons, the U.S. solid Earth science lead for the mission at Caltech in Pasadena, California.
Data from the satellite will give researchers insight into which parts of a fault slowly move without producing earthquakes and which sections are locked together and might suddenly slip. In relatively well-monitored areas like California, researchers can use NISAR to focus on specific regions that could produce an earthquake. But in parts of the world that aren’t as well monitored, NISAR measurements could reveal new earthquake-prone areas. And when earthquakes do occur, data from the satellite will help researchers understand what happened on the faults that ruptured.
“From the ISRO perspective, we are particularly interested in the Himalayan plate boundary,” said Sreejith K M, the ISRO solid Earth science lead for NISAR at the Space Applications Center in Ahmedabad, India. “The area has produced great magnitude earthquakes in the past, and NISAR will give us unprecedented information on the seismic hazards of the Himalaya.”
Surface motion is also important for volcano researchers, who need data collected regularly over time to detect land movements that may be precursors to an eruption. As magma shifts below Earth’s surface, the land can bulge or sink. The NISAR satellite will help provide a fuller picture for why a volcano deforms and whether that movement signals an eruption.
Finding Normal
When it comes to infrastructure such as levees, aqueducts, and dams, NISAR’s ability to provide continuous measurements over years will help to establish the usual state of the structures and surrounding land. Then, if something changes, resource managers may be able to pinpoint specific areas to examine. “Instead of going out and surveying an entire aqueduct every five years, you can target your surveys to problem areas,” said Jones.
The data could be equally valuable for showing that a dam hasn’t changed after a disaster like an earthquake. For instance, if a large earthquake struck San Francisco, liquefaction — where loosely packed or waterlogged sediment loses its stability after severe ground shaking — could pose a problem for dams and levees along the Sacramento-San Joaquin River Delta.
“There’s over a thousand miles of levees,” said Jones. “You’d need an army to go out and look at them all.” The NISAR mission would help authorities survey them from space and identify damaged areas. “Then you can save your time and only go out to inspect areas that have changed. That could save a lot of money on repairs after a disaster.”
More About NISAR
The NISAR mission is an equal collaboration between NASA and ISRO and marks the first time the two agencies have cooperated on hardware development for an Earth-observing mission. Managed for the agency by Caltech, JPL leads the U.S. component of the project and is providing the mission’s L-band SAR. NASA is also providing the radar reflector antenna, the deployable boom, a high-rate communication subsystem for science data, GPS receivers, a solid-state recorder, and payload data subsystem. The U R Rao Satellite Centre in Bengaluru, India, which leads the ISRO component of the mission, is providing the spacecraft bus, the launch vehicle, and associated launch services and satellite mission operations. The ISRO Space Applications Centre in Ahmedabad is providing the S-band SAR electronics.

This archival photo shows engineers working on NASA’s Voyager 2 spacecraft on March 23, 1977. NASA/JPL-Caltech NASA’s Voyager mission launched in the 1970s. Today, it’s making history as it conducts new science. But how are two spacecraft from the ’70s not just surviving, but thriving farther out in space than any other spacecraft has been before?
A Little Mission Background
Voyager is a NASA mission made up of two different spacecraft, Voyager 1 and 2, which launched to space on Sept. 5, 1977, and Aug. 20, 1977, respectively. In the decades following launch, the pair took a grand tour of our solar system, studying Jupiter, Saturn, Uranus, and Neptune — one of NASA’s earliest efforts to explore the secrets of the universe. These twin probes later became the first spacecraft to operate in interstellar space — space outside the heliosphere, the bubble of solar wind and magnetic fields emanating from the Sun. Voyager 1 was the first to enter interstellar space in 2012, followed by Voyager 2 in 2018.
Today, Voyager continues not just because it can, but because it still has work to do studying interstellar space, the heliosphere, and how the two interact. “We wouldn’t be doing Voyager if it wasn’t taking science data,” said Suzanne Dodd, the mission’s current project manager and the director for the Interplanetary Network at NASA’s Jet Propulsion Laboratory.
But across billions of miles and decades of groundbreaking scientific exploration, this trailblazing interstellar journey has not been without its trials. So, what’s the Voyager secret to success?
In short: preparation and creativity.
As NASA’s two Voyager spacecraft travel out into deep space, they carry a small American flag and a Golden Record packed with pictures and sounds — mementos of our home planet. This picture shows John Casani, Voyager project manager in 1977, holding a small Dacron flag that was folded and sewed into the thermal blankets of the Voyager spacecraft before they launched 36 years ago. Below him lie the Golden Record (left) and its cover (right). In the background stands Voyager 2 before it headed to the launch pad. The picture was taken at Cape Canaveral, Fla., on Aug. 4, 1977. NASA/JPL-Caltech We Designed Them Not to Fail
According to John Casani, Voyager project manager from 1975 to launch in 1977, “we didn’t design them to last 30 years or 40 years, we designed them not to fail.”
One key driver of the mission’s longevity is redundancy. Voyager’s components weren’t just engineered with care, they were also made in duplicate.
According to Dodd, Voyager “was designed with nearly everything redundant. Having two spacecraft — right there is a redundancy.”
“We didn’t design them to last 30 years or 40 years, we designed them not to fail.”
John Casani
Voyager Project Manager, 1975-1977
A Cutting-Edge Power Source
The twin Voyager spacecraft can also credit their longevity to their long-lasting power source.
Each spacecraft is equipped with three radioisotope thermoelectric generators. These nuclear “batteries” were developed originally by the U.S. Department of Energy as part of the Atoms for Peace program enacted by President Eisenhower in 1955. Compared to other power options at the time — like solar power, which doesn’t have the reach to work beyond Jupiter — these generators have allowed Voyager to go much farther into space.
Each of NASA’s Voyager probes are equipped with three radioisotope thermoelectric generators (RTGs), including the one shown here at NASA’s Kennedy Space Center in Florida. The RTGs provide power for the spacecraft by converting the heat generated by the decay of plutonium-238 into electricity. Launched in 1977, the Voyager mission is managed for NASA by the agency’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California.
NASA/JPL-Caltech Voyager’s generators continue to take the mission farther than any before, but they also continue to generate less power each year, with instruments needing to be shut off over time to conserve power.
Creative Solutions
As a mission that has operated at the farthest edges of the heliosphere and beyond, Voyager has endured its fair share of challenges. With the spacecraft now in interstellar space running on software and hardware from the 1970s, Voyager’s problems require creative solutions.
Retired mission personnel who worked on Voyager in its earliest days have even come back out of retirement to collaborate with new mission personnel to not just fix big problems but to pass on important mission know-how to the next generation of scientists and engineers.
“From where I sit as a project manager, it’s really very exciting to see young engineers be excited to work on Voyager. To take on the challenges of an old mission and to work side by side with some of the masters, the people that built the spacecraft,” Dodd said. “They want to learn from each other.”
After receiving data about the health and status of Voyager 1 for the first time in five months, members of the Voyager flight team celebrate in a conference room at NASA’s Jet Propulsion Laboratory on April 20. Credit: NASA/JPL-Caltech NASA/JPL-Caltech Within just the last couple of years, Voyager has tested the mission team’s creativity with a number of complex issues. Most recently, the thrusters on Voyager 1’s thrusters, which control the spacecraft’s orientation and direction, became clogged. The thrusters allow the spacecraft to point their antennae and are critical to maintaining communications with Earth. Through careful coordination, the mission team was able to remotely switch the spacecraft to a different set of thrusters.
These kinds of repairs are extra challenging as a radio signal takes about 22 ½ hours to reach Voyager 1 from Earth and another 22 ½ hours to return. Signals to and from Voyager 2 take about 19 hours each way.
Voyager’s Interstellar Future
This brief peek behind the curtain highlights some of Voyager’s history and its secrets to success.
The Voyager probes may continue to operate into the late 2020s. As time goes on, continued operations will become more challenging as the mission’s power diminishes by 4 watts every year, and the two spacecraft will cool down as this power decreases. Additionally, unexpected anomalies could impact the mission’s functionality and longevity as they grow older.
As the mission presses on, the Voyager team grows this legacy of creative problem solving and collaboration while these twin interstellar travelers continue to expand our understanding of the vast and mysterious cosmos we inhabit.
