NASA Selects Winners of Third TechRise Student Challenge

Source: NASA

NASA is announcing 60 winning teams for its third TechRise Student Challenge, a nationwide contest to engage students in technology, science, and space exploration. The student teams will work together to turn their proposed science and technology experiments into reality ahead of NASA-sponsored suborbital flight tests this summer.
The challenge opened for submissions in August to students in grades six through 12 at U.S. public, private, or charter schools, including those in U.S. territories. The winning teams include more than 490 students representing 46 states and territories. Their experiments will fly on one of two commercial suborbital flight platforms: a high-altitude balloon operated by World View of Tucson, Arizona, or the Xodiac rocket-powered lander operated by Astrobotic of Pittsburgh.
“Cultivating creativity and curiosity and inspiring students to pursue STEM careers is one of NASA’s most important missions,” said Prasun Desai, deputy associate administrator, Space Technology Mission Directorate at NASA Headquarters in Washington. “TechRise is a unique opportunity that allows students to gain hands-on knowledge while developing real payloads for flight, and it’s an experience they can carry with them during their educational and early career journeys.”
Winning proposals address a wide variety of science and technology challenges, including studying the effects of stratospheric conditions, such as solar and ionizing radiation on plant seeds; testing radiation shielding materials; and using sensors such as thermal cameras and lidar to map a simulated lunar surface.  
A complete list of winning teams is available on the TechRise website.
Each team will receive $1,500 to build their experiments, a flight box to house it, technical support from Future Engineers, and an assigned spot for their experiments on a suborbital flight test scheduled for this summer. The challenge is managed by NASA’s Flight Opportunities program, which rapidly demonstrates technologies for space exploration, discovery, and the expansion of space commerce through suborbital testing with industry flight providers.
Experiments tested on the high-altitude balloon will experience approximately four hours of flight time at approximately 70,000 feet with exposure to Earth’s upper atmosphere, high-altitude radiation, and perspective views of Earth. During flight, they will experience the stratosphere’s unique thermal and atmospheric environment, providing conditions that ground-based testing cannot replicate. The high-altitude balloon will also allow payloads to observe the surface below them and collect data on land features such as vegetation and bodies of water. 
Those tested on the lander will fly for approximately two minutes at an altitude of 80 feet over Astrobotic’s Lunar Surface Proving Ground, a test field designed to simulate the Moon’s surface, located at Astrobotic’s test site at the Mojave Air and Space Port in Mojave, California. During flight, payloads will be able to collect information on the features of the simulated lunar surface and discover hidden objects. Student experiments can also study the physics and characteristics of the lander’s flight environment. 
“I am most excited about the hands-on experience that building the NASA TechRise experiment will offer my students,” said Amy Becker, TechRise educator lead for the winning team from Clear Creek Middle School in Ellijay, Georgia. “They will not only acquire technical knowledge but also learn essential skills like effective communication and critical thinking. The prospect of seeing their ideas materialize into a tangible project, one that will ascend about 70,000 feet into the stratosphere, is both thrilling and educational.” 
A group of approximately 200 volunteer judges with expertise in engineering, space, and Earth science reviewed entries and selected the nationwide winners. Judges evaluated proposals based on experiment originality, its impact on education or society, feasibility within the allotted timeframe and budget, and the quality of the build plan. Criteria were also designed to encourage equitable student participation and geographic representation, and scoring included additional points for Title I-eligible schools.
Managed by NASA’s Flight Opportunities program at the agency’s Armstrong Flight Research Center in Edwards, California, and administered by Future Engineers, TechRise is designed to inspire a deeper understanding of Earth’s atmosphere, surface features, and climate. It also provides students the opportunity to learn more about space exploration, coding, electronics, and the value of test data. TechRise is one of many NASA Prizes, Challenges, and Crowdsourcing efforts within STMD offering opportunities to participate in America’s space program.

NASA’s 3D-printed Rotating Detonation Rocket Engine Test a Success

Source: NASA

NASA has achieved a new benchmark in developing an innovative propulsion system called the Rotating Detonation Rocket Engine (RDRE). Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, successfully tested a novel, 3D-printed RDRE for 251 seconds (or longer than four minutes), producing more than 5,800 pounds of thrust.
That kind of sustained burn emulates typical requirements for a lander touchdown or a deep-space burn that could set a spacecraft on course from the Moon to Mars, said Marshall combustion devices engineer Thomas Teasley, who leads the RDRE test effort at the center.
RDRE’s first hot fire test was performed at Marshall in the summer of 2022 in partnership with In Space LLC and Purdue University, both of Lafayette, Indiana. That test produced more than 4,000 pounds of thrust for nearly a minute. The primary goal of the latest test, Teasley noted, is to better understand how to scale the combustor to different thrust classes, supporting engine systems of all types and maximizing the variety of missions it could serve, from landers to upper stage engines to supersonic retropropulsion, a deceleration technique that could land larger payloads – or even humans – on the surface of Mars.

NASA, Partners Continue to Advance Space Tech on Suborbital Flights

Source: NASA

Living and working in space requires getting ready a bit closer to Earth. Through a suborbital flight test on Dec. 19, 2023 with industry provider Blue Origin, NASA’s Flight Opportunities program is helping 14 research payloads move one step toward future space missions and commercial applications. The flown technologies aim to address some of the opportunities and obstacles presented by humanity’s sustained presence in space.
Launched aboard Blue Origin’s New Shepard reusable suborbital rocket from the company’s Launch Site One in West Texas, the payloads reached an altitude of 351,248 feet. During the flight, those payloads experienced about three minutes of microgravity, providing insight into the effect of reduced gravity on both technologies and living things.  
“NASA relies on emerging commercial spaceflight capabilities to rapidly test disruptive solutions for space applications,” said Danielle McCulloch, program manager for Flight Opportunities at NASA’s Armstrong Flight Research Center in Edwards, California. “Working with commercial flight providers like Blue Origin allows the agency to make space exploration and commerce more accessible to a broader range of researchers.”
A strong commercial space industry also helps NASA move forward with scientific exploration of the moon, Mars, and beyond. In addition to the NASA supported research teams, this flight was also a significant milestone for Blue Origin, serving as the return to flight with their New Shepard rocket.

Sometimes, everyday products can be the key to advancing space objectives. For example, paraffin and beeswax aren’t just for cosmetics and candles. Researchers are using this flight to evaluate these common materials to determine if they might be keys to safer and cheaper fuel for spacecraft. Researchers from the Massachusetts Institute of Technology are evaluating in-space manufacturing techniques to turn these wax-based products into alternative options for propelling small spacecraft.
Also aboard the flight was a project from small business Ecoatoms Inc. in Reno, Nevada, designed to advance the production of biosensors in low Earth orbit. Earth’s gravity often causes the sensors to have rough and uneven layers that adversely affect performance. Fabrication in microgravity could allow for smoother and more uniform development, resulting in improved sensing. The startup expects the flight test with Blue Origin will be a step toward space-based manufacturing of health care tools for patients on Earth and astronauts on long-duration missions, improving crew safety while also leveraging the expanding space economy to benefit life on Earth.
“We are excited to test at-scale manufacturing of biosensors in space. Coating hundreds of sensors in microgravity will provide us with extremely valuable information to advance our technology,” said Solange Massa, Ecoatoms founder and CEO. “Preparing for suborbital flight with Flight Opportunities gave us experience we will apply to future flights for our clients.”
In another example of how a common substance can help pave the way to our understanding of space, researchers at Montana State University and the University of Colorado Boulder will use a yeast variant (Candida albicans) as a stepping stone to further understand how microgravity affects humans. Observations of how several minutes of microgravity affect this simple biological organism, made possible by the team’s unique sampling system, may provide a window into the cellular and physiological adaptations of the human body, which will be critical knowledge for planning extended human space missions.
 Other technologies benefiting from this flight testing include:
An electrophysiological measurement system and lens-free imaging system from imec USA in Kissimmee, Florida as well as two student payloads managed by imec examining gravity’s effect on ultrasonic sound waves and on a variety of sensors
An experiment from the University of Central Florida in Orlando to apply electric fields to a dust simulant
A tool for evaluating the geophysical properties of soil on near-Earth asteroids developed by Honeybee Robotics Ltd., in Altadena, California
A system from NASA’s Jet Propulsion Laboratory in Southern California to assess multiphase reservoirs for sample mixing and bubble migration
A system for propellant gauging during on-orbit refueling and transfer operations from Carthage College in Kenosha, Wisconsin
A technology from Purdue University in West Lafayette, Indiana for modeling propellant slosh in microgravity
The DMEN multi-environment navigator from Draper in Cambridge, Massachusetts
An experiment from the University of Alabama in Huntsville to collect thermal data of fluids in microgravity
A sensor to measure the volume of water used to keep an astronaut cool in an exploration spacesuit, developed by Creare in Hanover, New Hampshire and funded by NASA’s STTR (Small Business Technology Transfer) program
A regenerative technology to provide energy storage for spaceflight applications, developed by Infinity Fuel Cell in Windsor, Connecticut and funded by a NASA Tipping Point award through NASA’s Game Changing Development program
Flight Opportunities is managed at NASA Armstrong and funded by NASA’s Space Technology Mission Directorate. This program provides funding for flight tests and technology payload development as well as subject matter expertise to help researchers maximize the impact of their commercial flight tests. The program enables innovators to gather the data they need to advance their work ahead of larger, more expensive missions and applications.

University of Utah takes top honors in BIG Idea Lunar Forge Challenge 

Source: NASA

Through Artemis, NASA plans to conduct long-duration human and robotic missions on the lunar surface in preparation for future crewed exploration of Mars. Expanding exploration capabilities requires a robust lunar infrastructure, including practical and cost-effective ways to construct a lunar base. One method is employing in-situ resource utilization (ISRU) – or the ability to use naturally occurring resources – to produce consumables and build structures in the future, which will make explorers more Earth-independent.  
An ISRU process that NASA wants to learn more about is forging metals from lunar minerals to create structures and tools in the future. Through its 2023 Breakthrough, Innovative and Game-Changing (BIG) Idea Lunar Forge Challenge, NASA sought innovative concepts from university students to design an ISRU metal production pipeline on the Moon. The year-and-a-half-long challenge, funded by NASA’s Space Technology Mission Directorate (STMD) and Office of STEM Engagement, supports NASA’s Lunar Surface Innovation Initiative in developing new approaches and novel technologies to pave the way for successful exploration on the surface of the Moon.
Finalist teams presented their research, designs, prototypes, and testing results to a panel of NASA and industry judges at a culminating forum on Nov. 16, in Cleveland, Ohio.
The University of Utah team, partnering with Powder Metallurgy Research Laboratory, earned the Artemis Award, which represents top honors in the 2023 BIG Idea Challenge. Their lunar forge project, Production of Steel from Lunar Regolith through Carbonyl Iron Refining (CIR), represents a promising avenue to extract iron from reduced lunar regolith and refine it into a high purity powder product in a two-stage process. The Artemis Award is given to the team whose concept has the best potential to contribute to and be integrated into an Artemis mission.

Teams could select to address technologies needed along any point in the lunar metal production pipeline, including, but not limited to: 
Metal detecting 
Metal refining
Forming materials for additive manufacturing
Testing and qualifying 3D printed infrastructure for use on the Moon
In January, teams submitted proposal packages, from which seven finalists were selected in March 2023 for funding of up to $180,000, totaling nearly $1.1 million across all teams. The finalists then worked for nine months designing, developing, and demonstrating their concepts. The 2023 BIG Idea program concluded at its annual forum, where teams presented their results and answered questions from judges, followed by an interactive poster session. Experts from NASA and other aerospace companies evaluated the student concepts based on technical innovation, credibility, management, and teams’ verification testing. In addition to the presentation, the teams provided a technical paper and technical poster detailing their proposed metal production pipeline.

NASA Seeks Input for Future Lunar Surface Resource Utilization Demo

Source: NASA

As NASA ushers in an exciting era of long-term exploration on the Moon with Artemis, new strategies are being formulated to determine how technology, infrastructure, and operations will function together as a cohesive and cross-cutting system.
As a sustained presence grows at the Moon, opportunities to harvest lunar resources could lead to safer, more efficient operations with less dependence on Earth. Many new technologies in six priority areas encompassed by NASA’s Lunar Surface Innovation Initiative will need testing. For example, advancing In-situ Resource Utilization (ISRU) technologies could lead to future production of fuel, water, or oxygen from local materials, expanding exploration capabilities.
To support ISRU technology maturation, NASA issued a Request for Information (RFI) on Nov. 6 to formulate its future Lunar Infrastructure Foundational Technologies (LIFT-1) demonstration. Led by the Space Technology Mission Directorate (STMD), NASA’s primary objective for LIFT-1 is to demonstrate ISRU technologies to extract oxygen from lunar soil, to inform eventual production, capture, and storage. Additional LIFT-1 objectives may include demonstrating new landing technologies, surface operations, and scalable power generation in the Moon’s South Pole region.
With the RFI, NASA is asking for input from the lunar community to inform an integrated approach inclusive of launch, landing, and demonstration of surface infrastructure technologies as part of a subscale ISRU demonstration.
“The LIFT-1 demonstration creates a viable path to launch, land, and conduct operations on the lunar surface. This is the infusion path we need for ongoing industry and NASA center-led technology development activities,” said Dr. Prasun Desai, acting associate administrator of STMD at the agency’s Headquarters in Washington. “Using in-situ resources is essential to making a sustained presence farther from Earth possible. Just as we need consumables and infrastructure to live and work on our home planet, we’ll need similar support systems on the Moon for crew and robots to operate safely and productively.”
NASA has several current ISRU investments through partnerships with industry and academia. Prospecting, extraction, and mining initiatives are advancing our capabilities to find and harness resources from the lunar regolith. Chemical and thermal process developments may provide options to break down naturally occurring minerals and compounds found on the Moon and convert them to propellant or human consumables. Other potential longer-term applications could lead to extraterrestrial metal processing and construction of lunar surface structures using resources found on the Moon. Many of these technologies could be demonstrated and advanced on the Moon for future use at Mars. While the Moon has almost no atmosphere, Mars has an atmosphere rich in carbon dioxide, and NASA is investing in initiatives to use CO2 to create other useful elements or compounds.
MOXIE on NASA’s Mars Perseverance Rover marked the beginning of off-Earth ISRU technology demonstrations, successfully extracting oxygen from atmospheric carbon dioxide throughout a series of tests. NASA intends to demonstrate a similar capability on the lunar surface from its resources, and this RFI will help NASA capture stakeholder interest and ideas on how to partner, preferred acquisition approaches, and funding feasibility. This kind of input is critical to advancing innovative solutions that will help NASA and its partners explore the surface of the Moon for longer periods of time than ever before possible.
“An ISRU technology demonstration approach has been a topic of discussion within the Lunar Surface Innovation Initiative and Consortium communities for several years,” said Niki Werkheiser, director of Technology Maturation in STMD. “This RFI is the next phase to make it a reality.” 
The Lunar Surface Innovation Consortium (LSIC) was established by NASA in 2020 to coalesce government, academia, non-profit institutions, and the private sector to identify technological capabilities and hurdles that must be retired to achieve a sustained presence on the surface of the Moon, both human and robotic. 
The LIFT-1 RFI is available on NSPIRES and open for responses through Dec. 18, 2023, at 5:00 p.m. EST. NASA will host an industry forum on Monday, Nov. 13, 2023, at 1:00 p.m. EST.

NASA’s Innovative Rocket Nozzle Paves Way for Deep Space Missions

Source: NASA

By Ray Osorio
NASA recently built and tested an additively-manufactured – or 3D printed – rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more payloads.
Under the agency’s Announcement of Collaborative Opportunity, engineers from NASA’s Marshall Space Flight Center in Huntsville, Alabama, partnered with Elementum 3D, in Erie, Colorado, to create a weldable type of aluminum that is heat resistant enough for use on rocket engines. Compared to other metals, aluminum is lower density and allows for high-strength, lightweight components.
However, due to its low tolerance to extreme heat and its tendency to crack during welding, aluminum is not typically used for additive manufacturing of rocket engine parts – until now. 
Meet NASA’s latest development under the Reactive Additive Manufacturing for the Fourth Industrial Revolution, or RAMFIRE, project. Funded under NASA’s Space Technology Mission Directorate (STMD), RAMFIRE focuses on advancing lightweight, additively manufactured aluminum rocket nozzles. The nozzles are designed with small internal channels that keep the nozzle cool enough to prevent melting.

With conventional manufacturing methods, a nozzle may require as many as thousand individually joined parts. The RAMFIRE nozzle is built as a single piece, requiring far fewer bonds and significantly reduced manufacturing time. 
NASA and Elementum 3D first developed the novel aluminum variant known as A6061-RAM2 to build the nozzle and modify the powder used with laser powder directed energy deposition (LP-DED) technology. Another commercial partner, RPM Innovations (RPMI) in Rapid City, South Dakota, used the newly invented aluminum and specialized powder to build the RAMFIRE nozzles using their LP-DED process.
“Industry partnerships with specialty manufacturing vendors aid in advancing the supply base and help make additive manufacturing more accessible for NASA missions and the broader commercial and aerospace industry,” Paul Gradl, RAMFIRE principal investigator at NASA Marshall, said.

Paul Gradl
RAMFIRE Principal Investigator

NASA’s Moon to Mars objectives require the capability to send more cargo to deep space destinations. The novel alloy could play an instrumental role in this by enabling the manufacturing of lightweight rocket components capable of withstanding high structural loads.

“Mass is critical for NASA’s future deep space missions,” said John Vickers, principal technologist for STMD advanced manufacturing. “Projects like this mature additive manufacturing along with advanced materials, and will help evolve new propulsion systems, in-space manufacturing, and infrastructure needed for NASA’s ambitious missions to the Moon, Mars, and beyond.”
Earlier this summer at Marshall’s East Test Area, two RAMFIRE nozzles completed multiple hot-fire tests using liquid oxygen and liquid hydrogen, as well as liquid oxygen and liquid methane fuel configurations. With pressure chambers in excess of 825 pounds per square inch (psi) – more than anticipated testing pressures – the nozzles successfully accumulated 22 starts and 579 seconds, or nearly 10 minutes, of run time. This event demonstrates the nozzles can operate in the most demanding deep-space environments.

“This test series marks a significant milestone for the nozzle,” Gradl said. “After putting the nozzle through the paces of a demanding hot-fire test series, we’ve demonstrated the nozzle can survive the thermal, structural, and pressure loads for a lunar lander scale engine.”
In addition to successfully building and testing the rocket engine nozzles, the RAMFIRE project has used the RAMFIRE aluminum material and additive manufacturing process to construct other advanced large components for demonstration purposes. These include a 36-inch diameter aerospike nozzle with complex integral coolant channels and a vacuum-jacketed tank for cryogenic fluid applications.
NASA and industry partners are working to share the data and process with commercial stakeholders and academia. Various aerospace companies are evaluating the novel alloy and the LP-DED additive manufacturing process and looking for ways it can be used to make components for satellites and other applications.
