This project will investigate one of the key fundamental challenges associated with directed-energy light-sailing technology, similar to solar sails but powered by a laser beam pointed at the sail instead of by the sun. The effort will first mathematically model, then design, build, and test a prototype diffractive light sail. The three-dimensional, origami-inspired light sail could potentially unlock higher thrust, passive beam riding stability, and higher maneuverability via its ability to transform its shape.

NASA’s Jason Hopper is shown at the E Test Complex at NASA’s Stennis Space Center.NASA/Danny Nowlin Jason Hopper’s journey to NASA started with assessing the risk of stepping into the unknown.
One day, while taking a break from his hobby of rock climbing at Mississippi State University, a fellow student noticed Hopper reading a rocket propulsion textbook with a photo of a space shuttle launch on the cover.
Rocket propulsion – the technology that propels vehicles into space, usually through liquid rocket engines or solid rocket motors – is a highly complex field. Engineers rigorously test the propulsion systems and components to understand their capabilities and limitations, ensuring rockets can safely reach space.
“A guy just walked up and randomly said, ‘Hey, my dad works testing rocket engines,’” Hopper recalled.
Hopper, an aerospace engineering student at the time, did not know about NASA’s Stennis Space Center near Bay St. Louis, Mississippi. He soon would learn more.
The fellow student provided him with contact information, and the rest is history.
A Meridian, Mississippi, native, Hopper graduated from Mississippi State in 2007 and made his way to America’s largest rocket propulsion test site in south Mississippi.
On the other side of Hopper’s risk of stepping into the unknown came the reward of realizing how far he had come from reading about rocket propulsion work to contributing to it.
The career highlight happened when Hopper watched a space shuttle launch, powered in part by an engine he had fired up as a test conductor working at NASA Stennis.
“You cannot really put it into words because it permeates all through you, knowing that you are a part of something that big while at the same time, you are just a little piece of it,” he said.
Hopper transitioned from his contractor position to a civil servant role as test conductor when he joined NASA in 2011.
His work as a test conductor throughout all the NASA Stennis test areas and as test director at the E Test Complex has benefited NASA and industry, while giving him a good perspective on the value of the center’s work.
Among the projects he has played a large role in include the J-2X engine test program, build up for NASA’s SLS (Space Launch System) core stage hot fire ahead of the successful Artemis I launch and multiple projects throughout the E Test Complex.
“We offer operational excellence that I would argue you cannot get anywhere else,” Hopper said. “NASA Stennis is a smaller, family-oriented center renowned for excellence in rocket propulsion testing. It is a small place, where we do amazing things.”
Propulsion test customers at NASA Stennis include government and commercial projects. The NASA center is engaged in two projects to support the agency’s SLS rocket – testing of RS-25 engines to help power SLS launches and of NASA’s new exploration upper stage to fly on future missions to the Moon.
Current commercial companies conducting work at NASA Stennis include Blue Origin; Boeing; Evolution Space; Launcher, a Vast company; Relativity Space; and Rolls-Royce. Three companies – Relativity Space, Rocket Lab, and Evolution Space – are establishing production and/or test operations onsite.
After leaving south Mississippi for a four-year stint at NASA’s Marshall Spaceflight Center in Huntsville, Alabama, Hopper returned to NASA Stennis as risk manager of NASA’s Rocket Propulsion Test Program Office.
In his day-to-day work, Hopper assesses risk around two questions – what is the risk and what do I really need to be focusing on?
Making decisions through this filter helps the Poplarville, Mississippi, resident make the best use of the agency’s rocket propulsion test assets, activities, and resources.
“With a risk perspective, if things are high risk, we need to address these items and focus our attention on them,” Hopper said. “If we lose a national test capability, that impacts more than just NASA; it impacts the nation because NASA is a significant enabler of commercial spaceflight.”
Hopper helps oversee the maintenance and sustainment of propulsion test capabilities across four sites – NASA Stennis; NASA Marshall; NASA’s Neil Armstrong Test Facility in Sandusky, Ohio; and NASA’s White Sands Test Facility in Las Cruces, New Mexico.
By establishing and maintaining world-class test facilities, the agency’s Rocket Propulsion Test Program Office ensures that NASA and its partners can conduct safe, efficient, and cost-effective rocket propulsion tests to support the advancement of space exploration and technology development.
Hopper looks to the future with optimism.
“We have an opportunity to redefine kind of what we as NASA and NASA Stennis do and how we do it,” he said. “Before, we were trying to help commercial companies figure things out. We were trying to get them up and going, but now we are in more of a support role in a lot of ways and so if you look at it, and approach it the right way, it can be very exciting.”

NASA’s F-15D research aircraft is positioned adjacent to the X-59 during electromagnetic compatibility testing at U.S. Air Force Plant 42 in Palmdale, California. Researchers activated the F-15D’s radar, C-band transponder, and radios at different distances from the X-59 to evaluate potential electromagnetic interference with the aircraft’s flight-critical systems, ensuring the X-59 can operate safely with other aircraft. These tests showed that the aircraft’s integration is maturing and cleared a major hurdle that moves it one step closer to first flight.NASA/Carla Thomas NASA’s quiet supersonic X-59 research aircraft has cleared electromagnetic testing, confirming its systems will work together safely, without interference across a range of scenarios.
“Reaching this phase shows that the aircraft integration is advancing,” said Yohan Lin, NASA’s X-59 avionics lead. “It’s exciting to see the progress, knowing we’ve cleared a major hurdle that moves us closer to X-59’s first flight.”
Electromagnetic interference occurs when an electric or magnetic field source affects an aircraft’s operations, potentially impacting safety. This interference, whether from an external source or the aircraft’s own equipment, can disrupt the electronic signals that control critical systems – similar to effects that lead to static or crackling on a radio from a nearby emitting device, like a phone.
The tests, conducted at contractor Lockheed Martin Skunk Works’ facility in Palmdale, California, ensured that the X-59’s onboard systems – such as radios, navigation equipment, and sensors – did not interfere with one another or cause unexpected problems. During these tests, engineers activated each system on the aircraft one at a time while they monitored the other systems for possible interference.
NASA’s X-59 quiet supersonic research aircraft successfully completed electromagnetic interference (EMI) testing at Lockheed Martin Skunk Works in Palmdale, California. During EMI tests, the team examined each of the X-59’s internal electronic systems, ensuring they worked with one another without interference. The X-59 is designed to fly faster than the speed of sound while reducing the loud sonic boom to a quieter sonic thump.NASA/Carla Thomas “This testing helped us determine whether the systems within the X-59 are interfering with each other,” Lin said. “It’s called a source-victim test – essentially, we activate one system and monitor the other for issues like noise, glitches, faults, or errors.”
The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA’s Quesst mission, which will provide regulators with information that could help lift current bans on commercial supersonic flight over land. Currently, the aircraft is progressing through ground tests to ensure safety and performance. These included the recent, successful completion of a set of engine tests. The electromagnetic interference testing to examine the X-59’s internal electronic systems followed.
Other electromagnetic interference testing involved the team looking at the operation of the X-59’s landing gear, ensuring this critical component can extend and retract without affecting other systems. And they tested that the fuel switch shutoff was functioning properly without interference.
Electromagnetic compatibility was also assessed during this testing – making sure the X-59’s systems will function properly when it eventually flies near NASA research aircraft.
NASA test pilot Jim Less prepares to exit the cockpit of the quiet supersonic X-59 aircraft in between electromagnetic interference (EMI) testing. The EMI testing ensures an aircraft’s systems function properly under various conditions of electromagnetic radiation. The X-59 is the centerpiece of the NASA’s Quesst mission, designed to demonstrate quiet supersonic technology and provide data to address a key barrier to commercial supersonic travel.NASA/Carla Thomas Researchers staged the X-59 on the ground in front of NASA’s F-15D, placing them 47 feet apart, then 500 feet apart. The proximity of the two aircraft replicated conditions needed for the F-15D to use a special probe to gather measurements about the shock waves the X-59 will produce.
“We want to confirm there’s compatibility between the two aircraft, even at close proximity,” Lin said.
For the electromagnetic compatibility testing, the team powered up the X-59’s engine while turning on the F-15D’s radar, C-band radar transponder, and radios. Data from the X-59 were transmitted to NASA’s Mobile Operations Facility, where control room staff and engineers monitored for anomalies.
“You want to make discoveries of any potential electromagnetic interference or electromagnetic compatibility issues on the ground first,” Lin said. “This reduces risk and ensures we’re not learning about problems in the air.”
Now that electromagnetic testing is complete, the X-59 is ready to move on to aluminum bird tests – during which data will be fed to the aircraft on the ground under both normal and failure conditions – and then taxi tests before flight.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Artist concept highlighting the novel approach proposed by the 2025 NIAC awarded selection of the Fusion-Enabled Comprehensive Exploration of the Heliosphere conceptNASA/Ryan Weed Ryan Weed
Helicity Space LLC
This proposal aims to revolutionize space exploration by developing a constellation of spacecraft powered by the Helicity Drive, a compact and scalable fusion propulsion system. This innovative technology will enable rapid, multi-directional exploration of the heliosphere and beyond, providing unprecedented insights into the Sun’s vast influence on our solar system and its interaction with interstellar space. We will conduct a comprehensive feasibility study, including advanced modeling and experimental validation of the Helicity Drive’s thrust and power generation capabilities. We will also design a realistic spacecraft architecture that integrates the propulsion system with scientific instruments capable of measuring key properties of the heliosphere and interstellar medium. Each spacecraft will carry a suite of state-of-the-art scientific instruments to comprehensively measure plasma properties, magnetic fields, dust, and energetic particles, providing in-situ data from regions never before explored. This will address critical scientific questions, such as the true shape of the heliosphere and heliopause, the origin of anomalous cosmic rays, and the mechanisms driving turbulence in the heliospheric tail. Finally, we will develop a mission concept of operations that leverages the Helicity Drive’s variable specific impulse and high delta-V capability to speed-up and slow-down in order to capture key scientific data in different heliosphere regions, and the local interstellar medium along 6 different trajectories, maximizing scientific return. The successful implementation of this mission will not only revolutionize our understanding of the heliosphere and its implications for space radiation and habitability but also pave the way for future interstellar missions. By demonstrating the feasibility of fusion propulsion for deep-space exploration, including outer solar system probes and crewed missions to Mars, it will open new frontiers for scientific discovery and inspire future generations. The technological advancements and potential spinoffs resulting from this mission will also contribute significantly to the national economy.
