NASA selects new technologies for flight tests
Through NASA’s Space Technol- ogy Mission Directorate’s Flight Op- portunities program, six promising space technologies have been selected to be tested on commercial low-grav- ity-simulating aircraft and suborbital rockets.
The opportunity to fly on these vehicles helps advance technologies closer to practical use by taking them from a laboratory environment to the real world.
“The selected institutions will be able to demonstrate their technolo- gies that are of interest to NASA in a much more realistic environment than what can be done using ground-based simulation facilities,” said Stephan Ord, the program technology man- ager for NASA’s Flight Opportunities program. “This program is a valuable platform for NASA to mature cutting- edge technologies that have the poten- tial of supporting future exploration and agency mission needs.”
Two topics were included in this call for research. Under the first top- ic, which requested demonstration of space technology payloads, NASA selected five proposals:
• CubeSat Articulated Boom Op- tion Optimization in Microgravity (CABOOM); David Miles, principal investigator, University of Iowa, Iowa City
Demonstration of deploying a CubeSat boom arm with a magne-
tometer for surveying the Earth’s magnetic field. The zero-gravity test flight, which includes a test model mounted with optical sensors, will be used to characterize the deployment system and its repeatability. The flight provider will be Zero-G Corp.
• Investigation of Gravity Effects on Electrically Driven Liquid Film Boil- ing: A Microgravity Flight Campaign in Preparation of ISS Flight Experi- ment; Jamal Yagoobi, principal in- vestigator, Worcester Polytechnic Institute, Mass.
Demonstration of a new type of thermal management technique that moves liquid and evacuates vapor by applying an electric field to the sys- tem. This approach could significantly enhance heat transfer when compared to current pumped-loop systems and enables the next generation of high power electronics. The proposed work is planned to be used to advance a NASA-funded experiment on the In- ternational Space Station in 2021. The flight provider will be Zero-G Corp.
• Suborbital Testing of Liquid Ac- quisition Devices for Cryogenic Fluid Management; Kevin Supak, principal investigator, Southwest Research In- stitute, San Antonio
Liquid acquisition devices are cru- cial for cryogenic fluid management in space to properly feed propellant from a tank to the rocket engine. This dem- onstration flight will validate models
and predictions for a new technology using a tapered screen configuration to passively remove vapor bubbles from the liquid. The launch provider will be Blue Origin.
• Small-sat Propellant Management Technology; Steven Collicott, princi- pal investigator, Purdue University, West Lafayette, Ind.
Demonstration of a suite of pro- pellant tank shapes with propellant management devices to evaluate the zero-gravity control and draining per- formance of the system. The flight provider will be Zero-G Corp.
• Lightweight Strain-energy De- ployed Spacecraft Booms; Mark Pankow, principal investigator, North Carolina State University, Raleigh
Demonstration of a new and poten- tially more reliable boom deployment system for spacecraft using a strain- driven mechanism. The booms could be applied to deploy systems such as solar arrays or solar sail arms. The flight provider will be Zero-G Corp.
NASA selected one proposal under the second topic, demonstration of vehicle capability enhancements and onboard research facilities for payload accommodation:
• Human Tended Space Biology: Enabling Suborbital Genomics and Gene Expression; Robert Ferl, princi- pal investigator, University of Florida, Gainesville
Demonstration of Kennedy Space
Center Fixation Tubes on a suborbital vehicle that could be used to study gene expression changes during tran- sition from Earth gravity to micro- gravity and better understand flight effects on organisms. The launch pro- viders will be Blue Origin and Virgin Galactic.
The selected demonstrations will receive awards for payload integra- tion and flight costs, as well as lim- ited payload development costs. These investments take technologies from the laboratory to a relevant flight en- vironment, facilitate technology mat- uration, validate feasibility, reduce technical risks and enable infusion of key space technologies into multiple
future space missions. The most re- cent call for proposals in this series, called the REDDI Flight Opportuni- ties, opened on March 30, 2018.
The Flight Opportunities program is funded by NASA’s Space Technology Mission Directorate in Washington and managed at NASA’s Armstrong Flight Research Center in Edwards, California. NASA’s Ames Research Center in California’s Silicon Valley manages the solicitation and selec- tion of technologies to be tested and demonstrated on commercial flight vehicles.
