Preparations for Next Moonwalk Simulations Underway (and Underwater)
University of Florida researcher Rob Ferl (seated) and co-principal investigator Anna-Lisa Paul practice the experiment to study the effect of gravity transitions on the plants’ gene expression.University of Florida For the first time, a NASA-funded researcher will fly with their experiment on a commercial suborbital rocket. The technology is one of two NASA-supported experiments, also known as payloads, funded by the agency’s Flight Opportunities program that will launch aboard Blue Origin’s New Shepard suborbital rocket system on a flight test no earlier than Thursday, Aug. 29.
The researcher-tended payload, from the University of Florida in Gainesville, seeks to understand how changes in gravity during spaceflight affect plant biology. Researcher Rob Ferl will activate small, self-contained tubes pre-loaded with plants and preservative to biochemically freeze the samples at various stages of gravity. During the flight, co-principal investigator Anna-Lisa Paul will conduct four identical experiments as a control. After the flight, Ferl and Paul will examine the preserved plants to study the effect of gravity transitions on the plants’ gene expression. Studying how changes in gravity affect plant growth will support future missions to the Moon and Mars.
The university’s flight test was funded by a grant awarded through the Flight Opportunities program’s TechFlights solicitation with additional support from NASA’s Division of Biological and Physical Sciences. This experiment builds on NASA’s long history of supporting plant research and aims to accelerate the pace and productivity of space-based research.
The other Flight Opportunities supported payload is from HeetShield, a small business in Flagstaff, Arizona. Two new thermal protection system materials will be mounted to the outside of New Shepard’s propulsion module to assess their thermal performance in a relevant environment, since conditions will be similar to planetary entry. After the flight, HeetShield will analyze the structure of the materials to determine how they were affected by the flight.
Flight Opportunities, within NASA’s Space Technology Mission Directorate, facilitates demonstration of technologies for space exploration and the expansion of space commerce through suborbital testing with industry flight providers. Through various mechanisms, the program funds flight tests for internal and external technology payloads.

How Students Learn to Fly NASA’s IXPE Spacecraft
Amelia “Mia” De Herrera-Schnering is an undergraduate student at the University of Colorado, Boulder, and command controller for NASA’s IXPE mission at LASP. The large wall monitor displaying a countdown shows 17 seconds when Amelia “Mia” De Herrera-Schnering tells her teammates “We have AOS,” meaning “acquisition of signal.”
“Copy that, thank you,” Alexander Pichler replies. The two are now in contact with NASA’s IXPE (Imaging X-Ray Polarimeter Explorer) spacecraft, transmitting science data from IXPE to a ground station and making sure the download goes smoothly. That data will then go to the science team for further analysis.
At LASP, the Laboratory for Atmospheric and Space Physics, students at the University of Colorado, Boulder, can train to become command controllers, working directly with spacecraft on pointing the satellites, calibrating instruments, and collecting data. De Herrera-Schnering recently completed her sophomore year, while Pichler had trained as a student and now, having graduated, works as a full-time professional at LASP.
“The students are a key part in what we do,” said Stephanie Ruswick, IXPE flight director at LASP. “We professionals monitor the health and safety of the spacecraft, but so do the students, and they do a lot of analysis for us.”
Students also put into motion IXPE’s instrument activity plans, which are provided by the Science Operations Center at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The LASP student team schedules contacts with ground stations to downlink data, schedules observations of scientific and calibration targets, and generates the files necessary to translate the scientific operations into spacecraft actions. If IXPE experiences an anomaly, the LASP team will implement plans to remediate and resume normal operations as soon as possible.
Exploring the high-energy universe
The students take part in IXPE’s exploration of a wide variety of celestial targets. In October, for example, students monitored the transmission of data from IXPE’s observations of Swift J1727.8-1613, a bright black hole X-ray binary system. This cosmic object had been recently discovered in September 2023, when NASA’s Neil Gehrels Swift Observatory detected a gamma-ray burst. IXPE’s specialized instruments allow scientists to measure the polarization of X-rays, which contains information about the source of the X-rays as well as the organization of surrounding magnetic fields. IXPE’s follow-up of the Swift object exemplifies how multiple space missions often combine their individual strengths to paint a fuller scientific picture of distant phenomena.
Team members also conduct individual projects. For example, students analyzed how IXPE would fare during both the annular eclipse on Oct. 14, 2023, and the total eclipse that moved across North America on April 8, to make sure that the spacecraft would have adequate power while the Moon partially blocked the Sun.
While most of the students working on IXPE at LASP are engineering majors, some are physics or astrophysics majors. Some didn’t initially start their careers in STEM such as flight controller Kacie Davis, who previously studied art.
Prospective command controllers go through a rigorous 12-week summer training program working 40 hours per week, learning “everything there is to know about mission operations and how to fly a spacecraft,” Ruswick said.
Cole Writer, an aerospace engineering student, remembers this training as “nerve-wracking” because he felt intimidated by the flight controllers. But after practicing procedures on his own laptop, he felt more confident, and completed the program to become a command controller.
“It’s nice to be trained by other students who are in the same boat as you and have gone through the same process,” said Adrienne Pickerill, a flight controller who started with the team as a student and earned a Master’s in aerospace engineering at the university in May .
Sam Lippincott, right, a graduate student lead at LASP, trained as a command controller for NASA’s IXPE spacecraft as an undergraduate. In the background are flight controllers Adrienne Pickerill, left, and Alexander Pichler, who also trained as students. How they got here
As a teenager Writer’s interests focused on flying planes, and he saved money to train for a pilot’s license, earning it the summer after high school graduation. Surprisingly, he has found many overlaps in skills for both activities – following checklists and preventing mistakes. “Definitely high stakes in both cases,” he said.
Sam Lippincott, now a graduate student lead after serving as a command controller as an undergraduate, has been a lifelong sci-fi fan, but took a career in space more seriously his sophomore year of college. “For people that want to go into the aerospace or space operations industry, it’s always important to remember that you’ll never stop learning, and it’s important to remain humble in your abilities, and always be excited to learn more,” he said.
De Herrera-Schnering got hooked on the idea of becoming a scientist the first time she saw the Milky Way. On a camping trip when she was 10 years old, she spotted the galaxy as she went to use the outhouse in the middle of the night. “I woke up my parents, and we just laid outside and we were just stargazing,” she said. “After that I knew I was set on what I wanted to do.”
Rithik Gangopadhyay, who trained as an undergraduate command controller and continued at LASP as a graduate student lead, had been interested in puzzles and problem-solving as a kid and had a book about planets that fascinated him.. “There’s so much out there and so much we don’t know, and I think that’s what really pushed me to do aerospace and do this opportunity of being a command controller,” he said.
Coding is key to mission operations, and much of it is done in the Python language. Sometimes the work of flying a spacecraft feels like any other kind of programming — but occasionally, team members step back and consider that they are part of the grand mission of exploring the universe.
“If it’s your job for a couple of years, it starts to be like, ‘oh, let’s go ahead and do that, it’s just another Tuesday.’ But if you step back and think about it on a high-level basis, it’s really something special,” Pichler said. “It’s definitely profound.”

7 Min Read Spectral Energies is a NASA SBIR/STTR-Funded Tech that Could Change the Way We Fly

With $20 million in commercial sales and $15 million in sales to government agencies, minority-owned small business Spectral Energies, based in Beavercreek, Ohio, has found a customer base for its pulse-burst laser systems. NASA has played a significant role in developing the technology through the Small Business Innovation Research (SBIR) / Small Business Technology Transfer (STTR) program. With wide-ranging applications including metrology to support commercial aircraft certification, as well as material processing, this technology could pave the way for new forms of passenger aircraft.
The High Cost of Aircraft Certification
Did you know that the Boeing 737 first entered service in 1968? Yet there’s a good chance that, if you’ve flown recently, it was on a Boeing 737. That’s due in large part to the cost of certifying new airplanes, which can range in the hundreds of millions of dollars. One place to look for cost savings is the testing process.
When testing a new design for a space vehicle or commercial aircraft, researchers use wind tunnels to simulate flight conditions. The new aircraft or aircraft component—such as a new wing design—is built, put inside the wind tunnel, and evaluated.
NASA has long sought to develop robust modeling and prediction software to significantly reduce the need for wind tunnel testing and expensive flight testing. Such software would allow initial analysis to be done on a computer model to identify performance improvement opportunities and iterate on designs, saving the actual manufacturing and its associated costs for a design much closer to being final. Innovations in laser measurement systems could finally bring this goal within reach.
The Limitations of Traditional Lasers and Early Pulse-Burst Laser Systems
Entering into use in the 1980s and still widely used today, traditional commercial laser systems operate at 10 Hz, meaning they can fire 10 times per second into the air moving around an aircraft in a wind tunnel. This essentially provides a “photograph” of the air flow at that moment.
But a tenth of a second is a long time, especially when NASA wind tunnels can test vehicles at up to ten times the speed of sound. In a tenth of a second, the pocket of air from the previous image has long since moved on, meaning the second image is capturing something completely different than the first and crucial data is lost.
Why is this data crucial? Because when an aircraft has stalled, it’s the air flow—how the air moves over, under, and around the aircraft—that matters. This air flow changes rapidly in time, leading to effects like stall and buffet; measurement techniques need to be able to capture these rapid changes. Without a complete, data-backed understanding of air flow moment to moment, efforts to develop accurate modeling software have stalled.
In the late 1990s, pulse-burst laser systems came onto the scene and delivered a dramatic increase in measurement speed. These systems—developed in part with support from the NASA SBIR program—went from producing a set of photograph-like images to delivering a movie-like sequence of data. However, these early systems were difficult to transport and operate, significantly limiting their use.
NASA SBIR/STTR phasesCredits: NASA SBIR/STTR Enhancing Usability with Air Force SBIR Funding
By providing funding to develop early-stage technologies, the NASA SBIR/STTR program helps de-risk and develop ideas, maturing them to the point where others can continue innovating. More than a decade after helping to fund some of the earliest pulse-burst laser systems, NASA awarded Phase I SBIR funding to Spectral Energies in 2009 for further advancement of the technology.
The firm went on to receive Phase II and Phase III SBIR funding from the U.S. Air Force, leveraging these awards to create a commercial pulse-burst laser system that was smaller, easier to transport, more resilient and reliable, and simpler to operate due to significant software advancements. Air Force funding also enabled Spectral Energies to demonstrate several new applications of the system in combustion environments.
With this foundational work in place, the technology was ready for further innovation to help NASA pursue its long-held goal of more effective air flow measurement and modeling.
Spectral Energies work with the NASA SBIR/STTR program
Spectral Energies resumed its work with the NASA SBIR/STTR program in 2014 with multiple Phase I awards. Through continuing program awards, including three Phase II Extended (II-E) and three Phase III contracts, the firm added new capabilities to its pulse-burst laser system, such as high-speed two-color thermometry, demonstrated in 2020.
Previously, two-color thermometry was typically done at 10 Hz speeds with two lasers and two cameras. Spectral Energies worked with NASA to develop this capability at high-speed using their single-laser, single-camera system, thereby enabling three- and four-dimensional (i.e., three spatial coordinates and time) temperature measurement of chemical flows, a critical capability when designing new chemical propulsion systems.
Further collaboration with NASA yielded additional capabilities in high-speed picosecond velocimetry and two-dimensional ultraviolet spectroscopy and imaging. Adding these measurement techniques to its technology allowed Spectral Energies to make commercial inroads into hypersonic wind tunnel testing, material processing, and defense applications. Rather than modifying the pulse-burst laser system to deliver these capabilities, each enhancement took the form of an add-on that could be attached to the system, similar to how you can add apps to your smart phone or attach a new lens to your camera. These NASA SBIR-funded add-ons have increased the return on investment (ROI) for each of Spectral Energies’ customers across federal agencies, research universities, and commercial companies.
Growing a Small Business
For small businesses, the hunger to do more is often quelled by the reality of limited resources. As a result, necessity is often the biggest driver of decision-making: What do we need to do today to keep our doors open tomorrow? Funding from the NASA SBIR/STTR program allowed Spectral Energies to move into a different mindset and tap into their creative drive.
“Through the NASA program, we started diversifying in hypersonic test facilities from subsonic combustion facilities,” said Dr. Sukesh Roy, CEO of Spectral Energies, “and that opened many doors for the application of this laser, from detonation to directed energies. Without the funding from NASA, it would have been impossible for us to push for versatile technological enhancements that significantly broadened the application field.” Moving into the research and development of new applications allowed the company to widen its focus and ultimately find a larger customer base.
Spectral Energies’ continued work with the NASA SBIR/STTR program has helped the company further grow and succeed. By providing entry into new industries and new capabilities for existing customers, the add-on technologies developed with NASA SBIR-funding have generated significant commercial revenue for the small business. Additionally, these developments have opened the door for new funding opportunities with the Air Force, Navy, Army, and Missile Defense Agency.

Providing Benefit to NASA and Beyond
Dr. Paul Danehy, Senior Technologist for Advanced Measurement Systems at NASA’s Langley Research Center, has worked with Spectral Energies on a number of projects through the program. According to Dr. Danehy, not only did NASA SBIR funding aid the company’s technology growth, program funding also made it possible for NASA researchers to make use of this technology.
As Dr. Danehy explains, SBIR/STTR Post Phase II funding vehicles like Phase II-E and Phase III allow other programs within NASA to pool money together, then receive matching funds from the SBIR/STTR program. This matching funding increases the purchasing power of other NASA programs and has allowed the agency to acquire two of Spectral Energies’ pulse-burst laser systems, complete with add-ons.
Agency researchers are using these pulse-burst laser systems to obtain unique quantitative flow field measurements that will allow them to refine software codes to accurately design and evaluate new aerospace vehicles. In time, these software codes could cut hundreds of millions of dollars from the certification of commercial aircraft, allowing new planes to be developed and made available to passengers faster and cheaper.
