Celebrate the Heliophysics Big Year with Free Heliophysics and Math Webinars from NASA HEAT
The Heliophysics Big Year (HBY) is a global celebration of the Sun’s influence on Earth and the entire solar system. It began with the Annular Solar Eclipse on Oct. 14, 2023, continued through the Total Solar Eclipse on Apr. 8, 2024, and will conclude with Parker Solar Probe’s closest approach to the Sun in December 2024.
Challenged by the NASA Heliophysics Division to participate in as many Sun-related activities as possible, the NASA Heliophysics Education Activation Team (NASA HEAT) has been hosting a monthly webinar for formal and informal educators, science communicators, and other heliophysics enthusiasts to promote the understanding of heliophysics in alignment with monthly HBY themes. Each webinar’s content is designed with the Framework of Heliophysics Education in mind and maps directly to the Next Generation Science Standards (NGSS). Using the three main questions that heliophysicists investigate as a foundation, NASA HEAT cross-referenced heliophysics topics with the NGSS Disciplinary Core Ideas to create NGSS-aligned “heliophysics big ideas.” In each webinar, three math problems related to the theme are presented for beginner, intermediate, and advanced level learners. On average, there have been 30 attendees per webinar.

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.
Without the funding from NASA, it would have been impossible for us to push for versatile technological enhancements that significantly broadened the application field.
Dr. Sukesh Roy
CEO of Spectral Energies
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.

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.
From Polar Peaks to Celestial Heights: Christy Hansen’s Unique Path to Leading NASA’s Commercial Low Earth Orbit Development Program
Christy Hansen’s journey with NASA spans more than two decades and is marked by roles that have shaped her into a leader in space exploration. Now serving on a six-month rotation as the deputy manager for NASA’s CLDP (Commercial Low Earth Orbit Development Program) at Johnson Space Center in Houston, she brings 25 years of human spaceflight experience and a global perspective on Earth sciences to her role.
Prior to her rotation, she served as the Artemis deputy mission manager in the Moon to Mars Program Office at NASA Headquarters in Washington, where she supported Artemis missions and facilitated the integration of science and utilization activities into the mission architecture and planning.
Hansen now leverages her vast expertise to advance NASA’s commercial space initiatives and support the agency’s long-term goals.

She is no stranger to Johnson. From 1999 to 2010, Hansen worked as an operations engineer in Johnson’s Flight Operations Directorate, focusing on astronaut training and flight control. She developed procedures, planned spacewalks, and trained astronauts to work in space suits with specialty tools on Space Shuttle, International Space Station, and Hubble Space Telescope missions. She was instrumental in supporting real-time operations as a flight controller for space station assembly missions and the final mission to service Hubble in 2009.
In 2010, Hansen became the operations manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland for the Robotic Refueling Mission, a technology demonstration payload that flew to the orbiting laboratory on STS-135. By 2012 she transitioned to airborne science project management at Goddard, leading multiple missions including Operation IceBridge’s first deployment to Antarctica. Her work focused on studying changes in Earth’s ice sheets and sea ice in Greenland and Antarctica, where she collaborated with scientists, engineers, and managers to design aircraft-based Earth science missions.

Faced with her husband’s diagnosis of amyotrophic lateral sclerosis in 2014, Hansen drew on her vast experience and passion for engineering to solve a deeply personal issue on the ground. Combining her technical expertise and pioneering spirit, she led an effort to bring eye-gaze technology to Goddard, enabling individuals with neurodegenerative disabilities to continue working without the use of their hands or voice.
Her husband, Dave Parker, an engineer at Goddard who worked on all hubble servicing missions and tech demo payloads on the space station, was determined to keep working even when he could not use his arms, legs, hands, or voice. Together, they researched and pushed for this capability, ensuring that the technology could help many others in similar situations.
After collaborating with Goddard information technology and the commercial-off-the-shelf Tobi eye gaze company, they managed to implement the system within a year. Parker worked for a year and a half using this technology and supported the real-time installation of space station hardware he helped design from his hospital bed before passing away in March 2021.
Hansen continues to work with NASA’s Office of Diversity and Equal Opportunity to make this a standard accommodation option.
In her new role, she aims to support the development of an innovative acquisition strategy that fosters a robust commercial low Earth orbit environment. “I look forward to working with the CLDP team and our stakeholders to develop a creative and smart approach that enables a commercially led and operated low Earth orbit destination,” she said. “This includes fostering an open dialogue across disciplines, including critical tech authorities, programs, our industry and international partners, and Johnson and headquarters leadership. We can only go great places together.”
Her background in human spaceflight and science missions has given her a unique perspective. “I truly enjoy building partnerships and working across broad teams to achieve amazing goals,” she said. “This diversity of experience gave me an understanding of the critical goals, priorities, and culture of our key NASA stakeholders – and how we must integrate and work together to achieve the NASA mission.”
Through her career, she has learned to be open to new ideas and ways of doing things. “Be curious and proactively create space for all voices to be heard; there is more than one way to do things, and you must be open and receptive to different communication styles and experiences,” she said. “I lean on my broad experiences wherever I go.”

For young girls interested in a career in space, her advice is clear: “Go, go, go! You will face challenges and hurdles, but human spaceflight and NASA need your ideas, experiences, and energy. You uniquely bring momentum in a way others cannot – so don’t compare yourself to others. Study and do what you love – as that will get you through the hard times.”
Looking ahead, she is eager to help make space accessible and affordable to all, enabling a broader and diverse field of future flyers. “These destinations will enable critical science, human research, and tech development – important steppingstones to help us achieve our goals of landing on the Moon again and ultimately going to Mars,” she said. “No matter how dynamic and challenging our work is, my passion for human spaceflight and the NASA mission is inherently part of me.”
The agency’s commercial strategy for low Earth orbit will provide the government with reliable and safe services at a lower cost and enable the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

NASA Moon Rocket Stage for Artemis II Moved, Prepped for Shipment
NASA/Michael DeMocker
NASA is preparing the SLS (Space Launch System) rocket core stage that will help power the first crewed mission of NASA’s Artemis campaign for shipment. On July 6, NASA and Boeing, the core stage lead contractor, moved the Artemis II rocket stage to another part of the agency’s Michoud Assembly Facility in New Orleans. The move comes as teams prepare to roll the massive rocket stage to the agency’s Pegasus barge for delivery to NASA’s Kennedy Space Center in Florida in mid-July.
Prior to the move, technicians began removing external access stands, or scaffolding, surrounding the rocket stage in early June. NASA and Boeing teams used the scaffolding surrounding the core stage to assess the interior elements, including its complex avionics and propulsion systems. The 212-foot core stage has two huge propellant tanks, avionics and flight computer systems, and four RS-25 engines, which together enable the stage to operate during launch and flight.
The stage is fully manufactured and assembled at Michoud. Building, assembling, and transporting is a joint process for NASA, Boeing, and lead RS-25 engines contractor Aerojet Rocketdyne, an L3Harris Technologies company.
NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.
