NASA’s Flight Opportunities program supported the testing of 19 technologies in a series of parabolic flights in spring 2024. During brief periods of microgravity as well as lunar gravity, researchers collected data for projects that address several technology shortfalls across the civil space ecosystem. With this data, researchers will prepare for orbital demonstrations aboard the International Space Station, enhance their technologies for further suborbital testing, and share their findings with the scientific and technology community.

Large-Scope Bioprinting in Microgravity
Researchers from the Center for Applied Space Technology tested a bioprinter prototype as proof-of-concept for a full-scale, commercial bioprinting facility in low Earth orbit. Bioprinting in microgravity could allow for the large-scale production of cells and tissues more efficiently than on Earth.

Researchers from NASA’s Marshall Space Flight Center in collaboration with Sciperio and Redwire Space tested a newly developed advanced toolplate with eight miniaturized swappable toolheads for infusion into a low-gravity, on-demand manufacturing system for flexible, hybrid electronic devices currently under development. The technology is supported by the Space Mission Technology Directorate’s (STMD) Game Changing Development program under its ODME project.
Space Enabled Advanced Devices and Semiconductors (SEADS)
Researchers from NASA, industry, and academia took the first step in studying the use of a novel 3D printing technique that leverages electrohydrodynamic inkjet printing (EHD) to manufacture advanced memory devices in microgravity. This work is a continuation of prior parabolic flight tests in 2021 and 2022 to mature the technology. Collaborators included Intel, University of Wisconsin-Madison, Arizona State University, and Iowa State University. This technology is supported by the STMD Game Changing Development program under its ODME project, in conjunction with the Space Operations Mission Directorate’s (SOMD) In Space Productions Applications (InSPA).

Redwire Space tested a variety of liquid-handling processes associated with hardware designed to test multiple crystallization conditions in microgravity and provide samples back to Earth for analysis. The goal of this hardware is to provide services to pharmaceutical and institutional researchers seeking to use target molecules in their crystalline state to reformulate existing products and/or develop formulations for new products. The development of this hardware is supported by SOMD’s InSPA.
Acoustofluidics-Based Multifunctional Manipulation of Micro- and Nanoparticles
Researchers from Mississippi State University examined the acoustic effects on micro- and nanoparticles (or colloids) suspended in liquids under reduced gravity. Colloids have shown potential for additive manufacturing, drug delivery, and more. Researchers aim to develop a novel 3D printing platform that can actively manipulate colloids in reduced gravity, arranging them in resins and fabricating polymer composites containing patterned or aligned particles. This work is supported by NASA’s Established Program to Stimulate Competitive Research (EPScoR).
Noninvasive Detection of Liquid Propellant Location
Researchers from Carthage College tested their noninvasive propellant gauging technology designed to facilitate the transfer and storage of cryogenic propellants in microgravity – a key need for refueling of the power and propulsion element for future Gateway lunar station-keeping.

Massachusetts Institute of Technology researchers collected data to optimize models for cryogenic fluid management through predictive simulations of boiling heat transfer. Accurate modeling of phase change in cryogenic propellants is critical for long-duration crewed missions.
Stability of In-Space Cryogenic Systems
New Jersey Institute of Technology researchers gathered data to understand propellant stability during activities such as refueling, specifically as it relates to temperature and mechanical disturbances. The storage and transfer of cryogenic propellants in microgravity is important for lunar and deep space exploration.

Development of Cryogenic Propellant Storage Tank Inner Surface Coating
University of Florida researchers tested the effectiveness of several coating candidates to minimize or eliminate propellant boiloff, which can occur on a storage tank’s internal surface from external heat leakage and hotspots. The vapor generation due to boiloff can result in pressure buildup requiring the venting of propellant. Exploring and developing capabilities of the various coating materials and surface finish combinations could lead to substantial propellant savings.
Lightweight, Reliable Cryogenic Screen Channel Acquisition Devices

Effects of Extraterrestrial Gravity on Soil Fluidization Imposed by an Ultrasonic Probe
NASA’s Glenn Research Center tested a lunar excavation tool that leverages the use of forced, resonant vibration to fluidize soil around the leading edge of a probe or shovel, requiring less force for the tool to move through the soil. Reduction of excavation forces for a given tool can enable vehicle mass reduction and thereby reduce launch costs. Also supported by STMD’s Game Changing Development program, this technology for extraterrestrial mining or prospecting machinery could enable commodity production on the lunar surface.
