Technical Challenges (TCs) are finite-duration research and development endeavors supporting the strategic goals of NASA. The Hypersonic Technology project’s Technical Challenges include estimation of uncertainty for hypersonic research problems and vehicle systems, testing controls for switching engines mid-flight, and researching more efficient fuel combustors for large ramjets, which will be needed by future commercial high-speed planes.

Uncertainty Quantification

This Technical Challenge is complete!
TC-1: System-Level Uncertainty Quantification Methodology Development and Validation:
NASA developed and validated a system-level uncertainty propagation methodology to guide uncertainty-informed decision making by identifying fundamental research areas that will reduce the system performance uncertainty.

Turbine-Based Combined Cycle

TC-2: Turbine-Based Combined Cycle Mode Transition Technology Development: The Combined Cycle Mode Transition challenge demonstrates autonomous control and establishes performance/operability assessment methodologies for future reusable hypersonic propulsion systems that use turbine engines at slow speeds while transitioning to scramjets for high-speed operations. This challenge addresses the technology barrier of propulsion system mode transition via ground tests.

Improved Combustor Scaling Laws for Hypersonics

TC-3: Development of Improved Combustor Scaling Laws for Dual-Mode Ramjets: To improve current engine performance and enable engine scale up to fully reusable vehicle scales 100 times larger, NASA will develop and deliver mathematical models and associated validation test data with quantified uncertainty that support the design of high-speed combustors inclusive of green fuels. NASA will demonstrate such capability by reducing the length of the state-of-the-art cavity flameholder by 25 percent (10 percent threshold, 25 percent goal cavity length reduction relative to a state-of-the-art baseline.)

The Hypersonic Technology project is divided into four research topic areas. The first research topic is system-level design, analysis, and validation, which explores the impacts of technologies on vehicle performance. The second and third topics focus more specifically on propulsion technologies and vehicle technologies enabling hypersonic flight. The fourth topic area explores material technology that can survive and be reused in high-temperature hypersonic flight.

System-Level Design and Analysis

The System-Level Design, Analysis, and Validation research topic (RT-1) investments are focused on computational tool development and validation for hypersonic propulsion and vehicle system analysis methods including uncertainty quantification. RT-1 coordinates and performs definitive systems analysis studies to clarify the potential benefits of hypersonic vehicles and technologies for both high-speed civilian travel and space access and will use these studies to drive a technology portfolio focused on reusability, affordability, and reliability.

High Temperature Materials

The High Temperature Durable Materials research topic (RT-4) investments focus on advanced propulsion and vehicle materials research. Due to the operating conditions of hypersonic vehicles, most of the structures and materials are shared between propulsion and vehicle components, which include aeroshell, control surface, leading edge, propulsion, and sealing concepts. RT-4 examines the design and evaluation of potential structure and material concepts through component development and testing under relevant environments. In addition, because of the extreme environments the materials and structures must endure, RT-4 also includes development of advanced thermal and structural measurement methods.

NASA’s ELaNa 43 Prepares for Firefly Aerospace Launch

NASA’s ELaNa 43 Prepares for Firefly Aerospace Launch

A Satellite for Optimal Control and Imaging (SOC-i) CubeSat awaits integration at Firefly’s Payload Processing Facility at Vandenberg Space Force Base, California on Thursday, June 6, 2024. SOC-i, along with several other CubeSats, will launch to space on an Alpha rocket during NASA’s Educational Launch of Nanosatellites (ELaNa) 43 mission as part of the agency’s CubeSat Launch Initiative and Firefly’s Venture-Class Launch Services Demonstration 2 contract.
NASA

NASA is readying for the launch of several small satellites to space, built with the help of students, educators, and researchers from across the country, as part of the agency’s CubeSat Launch Initiative.

The ELaNa 43 (Educational Launch of Nanosatellites 43) mission includes eight CubeSats flying on Firefly Aerospace’s Alpha rocket for its “Noise of Summer” launch from Space Launch Complex-2 at Vandenberg Space Force Base, California. The 30-minute launch window will open at 9 p.m. PDT Wednesday, June 26 (12 a.m. EDT Thursday, June 27).

NASA’s CubeSat Launch Initiative (CSLI) is an ongoing partnership between the agency, educational institutions, and nonprofits, providing a path to space for educational small satellite missions. For the ELaNa 43 mission, each satellite is stored in a CubeSat dispenser on the Firefly rocket and deployed once it reaches sun-synchronous or nearly polar orbit around Earth.

CubeSats are built using standardized units, with one unit, or 1U, measuring about 10 centimeters in length, width, and height. This standardization in size and form allows universities and other researchers to develop cost-effective science investigations and technology demonstrations.

Read more about the small satellites launching on ELaNa 43:

CatSat – University of Arizona, Tucson

CatSat, a 6U CubeSat with a deployable antenna inside a Mylar balloon, will test high-speed communications. Once the CatSat reaches orbit, it will inflate to transmit high-definition Earth photos to ground stations at 50 megabits per second, more than five times faster than typical home internet speeds.

The CatSat design inspiration came to Chris Walker after covering a pot of pudding with plastic wrap. The CatSat principal investigator and professor of Astronomy at University of Arizona noticed the image of an overhanging light bulb created by reflections off the concave plastic wrap on the pot.

“This observation eventually led to the Large Balloon Reflector, an inflatable technology that creates large collecting apertures that weigh a fraction of today’s deployable antennas,” said Walker. The Large Balloon Reflector was an early-stage study developed through NASA’s Innovative Advanced Concepts program.

KUbeSat-1 – University of Kansas, Lawrence

The KUbeSat-1, a 3U CubeSat, will use a new method to measure the energy and type of primary cosmic rays hitting the Earth, which is traditionally done on Earth. The second payload, the High-Altitude Calibration will measure very high frequency signals generated by cosmic interactions with the atmosphere. KUbeSat-1 is Kansas’ first small satellite to launch under NASA’s CSLI.

MESAT-1 – University of Maine, Orono

MESAT-1, a 3U CubeSat, will study local temperatures across city and rural areas to determine phytoplankton concentration in bodies of water to help predict algal blooms.  MESAT-1 is Maine’s first small satellite to launch under NASA’s CSLI.

R5-S4, R5-S2-2.0 ­­­­­- NASA’s Johnson Space Center

R5-S4 and R5-S2-2.0, both 6U CubeSats, will be the first R5 spacecraft launched to orbit to test a new, lean spacecraft build. The team will monitor how each part of the spacecraft performs, including the computer, software, radio, propulsion system, sensors, and cameras in low Earth orbit.

“In the near term, R5 hopes to demonstrate new processes that allows for faster and cheaper development of high-performance CubeSats,” said Sam Pedrotty, R5 project manager at NASA’s Johnson Space Center in Houston. “The cost and schedule improvements will allow R5 to provide higher-risk ride options to low-Technology Readiness Levels payloads so more can be demonstrated on-orbit.”

Serenity Teachers in Space

Serenity, a 3U CubeSat equipped with data sensors and a camera, will communicate with students on Earth through amateur radio signals and send back images. Teachers in Space launches satellites as educational experiments to stimulate interest in space science, technology, engineering, and math among students in North America.

SOC-i University of Washington, Seattle

Satellite for Optimal Control and Imaging (SOC-i), a 2U CubeSat, is a technology demonstration mission of attitude control technology used to maintain its orientation in relation to the Earth, Sun, or other body. This mission will test an algorithm to support autonomous operations with constrained attitude guidance maneuvers computed in real-time aboard the spacecraft. SOC-i will autonomously rotate its camera to capture images.

TechEdSat-11 (TES-11) – NASA’s Ames Research Center, California’s Silicon Valley

TES-11, a 6U CubeSat, is a collaborative effort between NASA researchers and students to evaluate technologies for use in small satellites. It’s part of ongoing experiments to evaluate new technologies in communications, a radiation sensor suite, and experimental solar panels, as well as to find ways to reduce the time to de-orbit.

NASA awarded Firefly Aerospace a fixed-price contract to fly small satellites to space under a Venture-Class Launch Services Demonstration 2 contract in 2020. NASA certified Firefly Aerospace’s Alpha rocket as a Category 1 in May, which authorized its use during missions with high risk tolerance.

NASA’s Launch Services Program is responsible for launching rockets delivering spacecraft that observe Earth, visit other planets, and explore the universe.
