NASA and Peru’s National Commission for Aerospace Research and Development (CONIDA) laid the groundwork for a potential multi-year scientific rocket launch campaign in the South American country.

Both countries signed a non-binding memorandum of understanding Thursday that includes safety training, a joint feasibility study for the potential campaign, and technical assistance for CONIDA on sounding rocket launches. Sounding rockets are small, low-cost rockets that provide suborbital access to space.

“We are excited to look at the possibility of once again launching sounding rockets from Peru,” said NASA Administrator Bill Nelson, who signed on behalf of the United States. “This agreement deepens our international partnership with Peru and the scientific research we conduct because of the country’s location along the magnetic equator. Together we will go farther.” 

Maj. Gen. Roberto Melgar Sheen, head of CONIDA, signed on behalf of Peru. Brian Nichols, assistant secretary for Western Hemisphere Affairs for the U.S. State Department, and Stephanie Syptak-Ramnath, U.S. ambassador to Peru, also participated, among other Peruvian officials. The event took place during the week of the Asia-Pacific Economic Cooperation forum beginning Nov. 9 in Lima.

During his visit to Peru, Nelson also discussed the importance of international partnerships and collaboration in space and celebrated Peru’s signing of the Artemis Accords earlier this year.

The United States and Peru have a long history of space cooperation. NASA conducted sounding rocket campaigns at CONIDA’s Punta Lobos launch base in 1975 and 1983.

NASA uses sounding rockets to carry scientific instruments into space on suborbital flights to collect important science data and test prototype instruments. They yield invaluable data that enhance our understanding of Earth’s atmosphere and weather, our solar system, and the universe, and test equipment for deeper space travel.

Understanding our Earth’s atmosphere and how it is influenced by the Sun is crucial to protecting ground and space-based assets that we rely on every day, from the power grid to weather data and even navigation.

      NASA has selected 12 student teams to develop solutions for storing and transferring the super-cold liquid propellants needed for future long-term exploration beyond Earth orbit.
      The agency’s 2025 Human Lander Challenge is designed to inspire and engage the next generation of engineers and scientists as NASA and its partners prepare to send astronauts to the Moon through the Artemis campaign in preparation for future missions to Mars. The commercial human landing systems will serve as the primary mode of transportation that will safely take astronauts and, later, large cargo from lunar orbit to the surface of the Moon and back.
      For its second year, the competition invites university students and their faculty advisors to develop innovative, “cooler” solutions for in-space cryogenic, or super cold, liquid propellant storage and transfer systems. These cryogenic fluids, like liquid hydrogen or liquid oxygen, must stay extremely cold to remain in a liquid state, and the ability to effectively store and transfer them in space will be increasingly vital for future long-duration missions. Current technology allows cryogenic liquids to be stored for a relatively short amount of time, but future missions will require these systems to function effectively over several hours, weeks, and even months.
      The 12 selected finalists have been awarded a $9,250 development stipend to further develop their concepts in preparation for the next stage of the competition.
      The 2025 Human Lander Challenge finalist teams are:
      California State Polytechnic University, Pomona, “THERMOSPRING: Thermal Exchange Reduction Mechanism using Optimized SPRING” Colorado School of Mines, “MAST: Modular Adaptive Support Technology” Embry-Riddle Aeronautical University, “Electrical Capacitance to High-resolution Observation (ECHO)” Jacksonville University, “Cryogenic Complex: Cryogenic Tanks and Storage Systems – on the Moon and Cislunar Orbit” Jacksonville University, “Cryogenic Fuel Storage and Transfer: The Human Interface – Monitoring and Mitigating Risks” Massachusetts Institute of Technology, “THERMOS: Translunar Heat Rejection and Mixing for Orbital Sustainability” Old Dominion University, “Structural Tensegrity for Optimized Retention in Microgravity (STORM)” Texas A&M University, “Next-generation Cryogenic Transfer and Autonomous Refueling (NeCTAR)” The College of New Jersey, “Cryogenic Orbital Siphoning System (CROSS)” The Ohio State University, “Autonomous Magnetized Cryo-Couplers with Active Alignment Control for Propellant Transfer (AMCC-AAC) University of Illinois, Urbana-Champaign, “Efficient Cryogenic Low Invasive Propellant Supply Exchange (ECLIPSE)” Washington State University, “CRYPRESS Coupler for Liquid Hydrogen Transfer” Finalist teams will now work to submit a technical paper further detailing their concepts. They will present their work to a panel of NASA and industry judges at the 2025 Human Lander Competition Forum in Huntsville, Alabama, near NASA’s Marshall Space Flight Center, in June 2025. The top three placing teams will share a total prize purse of $18,000.
      “By engaging college students in solving critical challenges in cryogenic fluid technologies and systems-level solutions, NASA fosters a collaborative environment where academic research meets practical application,” said Tiffany Russell Lockett, office manager for the Human Landing System Mission Systems Management Office at NASA Marshall. “This partnership not only accelerates cryogenics technology development but also prepares the Artemis Generation – the next generation of engineers and scientists – to drive future breakthroughs in spaceflight.”
      NASA’s Human Lander Challenge is sponsored by the agency’s Human Landing System Program within the Exploration Systems Development Mission Directorate and managed by the National Institute of Aerospace.

      5 Min Read NASA Langley’s Legacy of Landing
      The first image of the Moon taken by the cameras on the Lunar Orbiter in 1966. Credits: NASA Landing safely on the surface of another planetary body, like the Moon or Mars, is one of the most important milestones of any given space mission. From the very beginning, NASA’s Langley Research Center has been at the heart of the entry, descent and landing (EDL) research that enables our exploration. Today, NASA Langley’s legacy of landing continues at the forefront of present day lunar missions and as NASA prepares for future travel to more distant worlds.
      Project Mercury: 1958
      Project Mercury was the United States’ first human-in-space program, led by NASA’s Space Task Group located at NASA Langley. There were five major programs of study and experimentation.
      An airdrop study that helped us understand the characteristics of the Mercury capsule as it returned to Earth. A group of study focused on the escape systems, ultimately becoming known as the launch abort system. Exhaustive wind-tunnel studies of the blunt-nosed capsule design and its aerodynamic stability at various altitudes and speeds and angles of reentry, all with a focus on making the capsule safe and stable. A study on the problem of landing impact, resulting in the development of absorption systems that minimized the shock of impact to the capsule’s pilot. Studies into the use of drogue parachutes and their characteristics at high altitudes and speeds, ensuring that they would be able to stabilize and slow the capsule’s descent for a safe landing. All of this research went on to inform the subsequent Gemini and Apollo programs. All of this research went on to inform the subsequent Gemini and Apollo programs.
      Apollo Program: 1962
      In 1961, President John F. Kennedy committed to putting Americans on the surface of the Moon and shortly after that historic declaration, NASA’s Apollo program was born. In the years that followed, the original team of NASA astronauts completed their basic training at NASA Langley’s Lunar Landing Research Facility (LLRF). When Apollo 11 successfully landed the first humans on the Moon in 1969, NASA Langley had played a pivotal role in the monumental success.
      Lunar Orbiter: 1966
      The Lunar Orbiter missions launched with the purpose of mapping the lunar surface and identifying potential landing sites ahead of the Apollo landings. From 1966 to 1967, the five successful Lunar Orbiter missions, led and managed by Langley Research Center, resulted in 99% of the moon photographed and a suitable site selected for the upcoming human landings.
      Viking: 1976
      After the success of Apollo, NASA set its sights further across the solar system to Mars. Two Viking missions aimed to successfully place landers on the Red Planet and capture high resolution images of the Martian surfaces, assisting in the search for life. Langley Research Center was chosen to lead this inaugural Mars mission and went on to play key roles in the missions to Mars that followed.
      HIAD: 2009 – Present
      Successful landings on Mars led to more ambitious dreams of landing larger payloads, including those that could support future human exploration. In order to land those payloads safely, a new style of heat shield would be needed. Hypersonic Inflatable Aerodynamic Decelerator (HIAD) technology was positioned as an answer to the payload problem, enabling missions to use inflatable heat shields to slow down and protect a payload as it enters a planet’s atmosphere at hypersonic speeds.
      IRVE – 2009-2012
      Two successful Inflatable Reentry Vehicle Experiments (IRVE) proved the capability of inflatable heat shield technology and opened the door for larger iterations.
      LOFTID – 2022
      The Low Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) followed in the footsteps of its predecessor IRVE with a larger aeroshell that could be deployed to a scale much larger than the shroud. The 2022 successful test of this technology further proved the capability of HIAD technology.
      MEDLI 1 and 2: 2012 & 2020
      As a part of the Mars Science Laboratory (MSL) mission, NASA Langley’s Mars Entry, Descent and Landing Instrument (MEDLI) was designed to gather data from the MSL entry vehicle’s heatshield during its entry and descent to the surface of Mars. MEDLI2 expanded on that groundbreaking data during the Mars 2020 mission which safely landed the Perseverance rover after successfully entering the planet’s arid atmosphere, and enabling improvements on the design for future entry systems.
      Curiosity Rover
      Curiosity was the largest and most capable rover ever sent to Mars when it launched in 2011. Leading up the mission, Langley engineers performed millions of simulations of the entry, descent and landing phase — or the so-called “Seven Minutes of Terror” — that determines success or failure. Curiosity continues to look for signs that Mars once was – or still is – a habitable place for life as we know it.
      CLPS: 2023 – Present
      The Commercial Lunar Payload Services initiative takes the Artemis mission further by working with commercial partners to advance the technology needed to return humans to the Moon and enable humanity to explore Mars.
      NDL
      Navigation Doppler Lidar (NDL) technology, developed at Langley Research Center, uses lasers to assist spacecraft in identifying safe locations to land. In 2024, NDL flew on the Intuitive Machines’ uncrewed Nova-C lander, with its laser instruments designed to measure velocity and altitude to within a few feet. While NASA planetary landers have traditionally relied on radar and used radio waves, NDL technology has proven more accurate and less heavy, both major benefits for cost and space savings as we continue to pursue planetary missions.
      SCALPSS
      Like Lunar Orbiter and the Viking missions before it, Stereo Cameras for Lunar Plume Surface Studies (SCALPSS) set out to better understand the surface of another celestial body. These cameras affixed to the bottom of a lunar lander focus on the interaction between the lander’s rocket plumes and the lunar surface. The SCALPSS 1.1 instrument captured first-of-its-kind imagery as the engine plumes of Firefly’s Blue Ghost lander reached the Moon’s surface. These images will serve as key pieces of data as trips to the Moon increase in the coming years.

      An electron microscopy images of multicellular magnetotactic bacteria that featured on the covers of the 2022 edition of The ISME Journal. The image was produced by Schaible and co-workers under the group’s NASA awards.Roland Hatzenpichler / Montana State University In a recent study, NASA-supported researchers gained new insight into the lives of bacteria that survive by grouping together as if they were a multi-cellular organism. The organisms in the study are the only bacteria known to do this in this way, and studying them could help astrobiologists explain important steps in the evolution of life on Earth.
      The organisms in the study are known as ‘multicellular magnetotactic bacteria,’ or MMB. Being magnetotactic means that MMB are part of a select group of bacteria that orient their movement based on Earth’s magnetic field using tiny ‘compass needles’ in their cells. As if that wasn’t special enough, MMB also live bunched up in collections of cells that are considered by some scientists to exhibit ‘obligate’ multicellularity, which is the trait the new study is focused on.
      In biology, obligate means that an organism requires something for survival. In this case, it means that single cells of MMB cannot survive on their own. Instead, cells live as a consortium of multiple cells that behave in many ways like a single multicellular organism. This requirement to live together means that when MMB reproduce, they do so by replicating all the cells in the consortium at once, doubling the total number of cells. This large group of cells then splits into two identical consortia.
      Electron microscopy image and cartoon of a MMB consortium, highlighting its characteristics features that includes a hollow space at the center of the cell consortium.George Shaible et al. PLOS Biology 2024 MMB are the only example of bacteria that are known to live like this. Many other bacteria clump together as simple aggregates of single cells. For instance, cyanobacteria clump together in colonies and form structures like stromatolites or biofilms that are visible to the naked eye. However, unlike MMB, these cyanobacteria can also survive as single, individual cells.
      In the new study, scientists have revealed even more complexity in the relationships between MMB cells. First, contrary to long-held assumptions, individual cells within MMB consortia are not genetically identical, they differ slightly in their genetic blueprint. Further, cells within a consortium exhibit different and complementary behavior in terms of their metabolism. Each cell in an MMB consortium has a role that contributes to the survival of the entire group. This behavior is similar to how individual cells within multicellular organisms behave. For example, human bodies are made up of tens of trillions of cells. These cells differentiate into specific cell types with different functions. Bone cells are not the same as blood cells. Fat cells that store energy are different from the nerve cells that store and transmit information. Each cell has a role to play, and together they make up a single living body. 
      The proposed life cycle of multicellular magnetotactic bacteria (MMB). Credit: George ShcaibleGeorge Schaible The evolution of multicellularity is one of the major transitions in the history life on our planet and had profound effects on Earth’s biosphere. In the wake of its appearance, life developed novel strategies for survival that led to entirely new ecosystems. As the only example of bacteria that exhibit obligate multicellularity, MMB provide an important example of possible mechanisms behind this profound step in life’s evolutionary history on Earth.
      The study, “Multicellular magnetotactic bacteria are genetically heterogeneous consortia with metabolically differentiated cells,” was published in PLOS Biology. The work was supported through the NASA Exobiology program and the Future Investigators in NASA Earth and Space Science and Technology (FINESST) program.
