MuSat2 at Vandenberg Air Force Base, prior to launch. MuSat2 leverages a dual-frequency science antenna developed with support from NASA to measure phenomena such as ocean wind speed. Muon Space A science antenna developed with support from NASA’s Earth Science Technology Office (ESTO) is now in low-Earth orbit aboard MuSat2, a commercial remote-sensing satellite flown by the aerospace company Muon Space. The dual-frequency science antenna was originally developed as part of the Next Generation GNSS Bistatic Radar Instrument (NGRx). Aboard MuSat2, it will help measure ocean surface wind speed—an essential data point for scientists trying to forecast how severe a burgeoning hurricane will become.
“We’re very interested in adopting this technology and pushing it forward, both from a technology perspective and a product perspective,” said Jonathan Dyer, CEO of Muon.
Using this antenna, MuSat2 will gather signals transmitted by navigation satellites as they scatter off Earth’s surface and back into space. By recording how those scattered navigation signals change as they interact with Earth’s surface, MuSat2 will provide meteorologists with data points they can use to study severe weather.
“We use the standard GPS signals you know—the navigation signals that work for your car and your cell phone,” explained Chris Ruf, director of the University of Michigan Space Institute and principal investigator for NGRx.
Ruf designed the entire NGRx system to be an updated version of the sensors on NASA’s Cyclone Global Navigation Satellite System (CYGNSS), another technology he developed with support from ESTO. Since 2016, data from CYGNSS has been a critical resource for people dedicated to forecasting hurricanes.
The science antenna aboard MuSat2 enables two key improvements to the original CYGNSS design. First, the antenna allows MuSat2 to gather measurements from satellites outside the U.S.-based GPS system, such as the European Space Agency’s Galileo satellites. This capability enables MuSat2 to collect more data as it orbits Earth, improving its assessments of conditions on the planet’s surface.
Second, whereas CYGNSS only collected cross-polar radar signals, the updated science antenna also collects co-polar radar signals. This additional information could provide improved information about soil moisture, sea ice, and vegetation. “There’s a whole lot of science value in looking at both polarization components scattering from the Earth’s surface. You can separate apart the effects of vegetation from the effects of surface, itself,” explained Ruf.

NASA For Muon Space, this technology infusion has been helpful to the company’s business and science missions. Dallas Masters, Vice President of Muon’s Signals of Opportunity Program, explains that NASA’s investments in NGRx technology made it much easier to produce a viable commercial remote sensing satellite. According to Masters, “NGRx-derived technology allowed us to start planning a flight mission early in our company’s existence, based around a payload we knew had flight heritage.”
Dyer agrees. “The fact that ESTO proves out these measurement approaches – the technology and the instrument, the science that you can actually derive, the products from that instrument – is a huge enabler for companies like ours, because we can adopt it knowing that much of the physics risk has been retired,” he said.
Ultimately, this advanced antenna technology for measuring ocean surface wind speed will make it easier for researchers to turn raw data into actionable science products and to develop more accurate forecasts.
“Information is absolutely precious. When it comes to forecast models and trying to understand what’s about to happen, you have to have as good an idea as you can of what’s already happening in the real world,” said oceanographer Lew Gramer, an Associate Scientist with the Cooperative Institute For Marine And Atmospheric Studies and NOAA’s Hurricane Research Division.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Engineer Adam Gannon works on the development of Cognitive Engine-1 in the Cognitive Communications Lab at NASA’s Glenn Research Center.Credit: NASA Automated technology developed in Cleveland has launched to space aboard the Technology Education Satellite 11 mission. The flight test aims to confirm the precision and accuracy of this new technology developed at NASA’s Glenn Research Center.
The Cognitive Communications Project was founded by NASA in 2016 to develop autonomous space communications systems for the agency. Autonomous systems use technology that can react to its environment to implement updates during a mission, without needing any human interaction.
The project first collaborated with the Technology Education Satellite (TES) program at NASA’s Ames Research Center in California’s Silicon Valley back in 2022 to launch the TES-13 CubeSat, which sent the first neuromorphic processor to space. A neuromorphic processor is a piece of technology built to act in ways that replicate how the human brain functions. Through TES-13, the cognitive team was able to test their advanced technology in space successfully for the first time.

CE-1 is a space and ground software system that automates normal aspects of spacecraft communications, like service scheduling and planning reliable priority-based data transfers.
Cognitive technology launched to space for the second time on July 3 on TES-11 aboard Firefly Aerospace’s Noise of Summer mission. TES-11 was one of eight small satellites launched during the mission. It was created as a part of the Technology Education Satellite program at NASA Ames, which organizes collaborative projects and missions that pair college and university students with NASA researchers to evaluate how new technologies work on small satellites, known as CubeSats.

Credit: NASA TES-11 is testing the components of CE-1 that allow satellites to independently schedule time with ground stations and download data without human interaction. Results from the TES-11 mission will be used by the Cognitive Communications team to finalize their CE-1 design, to ensure that the technology is ready to be adopted by future NASA missions.
The Cognitive Communications Project is funded by the Space Communications and Navigation program at NASA Headquarters in Washington and managed out of NASA’s Glenn Research Center in Cleveland.

Michael Zanetti (ST13), Kyle Miller (EV42), and Chris Whetsel (ES52) conducted a technology demonstration and field work with the NASA JSC 5th Joint EVA Test Team (JETT-3) from 5/17-23/24, near SP Crater, Flagstaff, AZ. JETT5 tested full-up mission operations with communication to JSC-Houston, and included astronauts Kate Rubins and Andre Douglas testing ATLAS suits and 4-6 hr. planned traverses near SP-Crater – a former Apollo astronaut geology training site. The Kinematic Navigation and Cartography Knapsack (KNaCK) team members were invited to demonstrate GPS-denied navigation solutions using our person-mounted velocity-sensing LiDAR sensors that provide local position and a ground-track in addition to terrain mapping capabilities using terrain relative navigation and LiDAR SLAM algorithms. KNaCK tests were designed to provide a real-time ground-track to the Joint Augmented Reality (JointAR/JARVIS) heads-up display suit from NASA JSC. Our technology demo had Astronaut Kate Rubins in the JARVIS suit receiving real-time updates of her traverse path. KNaCK provided flawless positioning for 75% of the traverse, with ~2 m local accuracy compared to GPS. The remaining 25% of the run was impacted by algorithm issues in perfectly flat terrain (a rare issue, likely only on Earth, causing 3 restarts to reacquire an accurate ground-track). Overall, the KNaCK tech demo mission was a big success, with Kate Rubins noting Navigation accuracy reducing mental overhead and decreasing traverse time to sampling stations “Definitely giving me what I need. Pretty Cool!”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA used its remotely piloted Ikhana aircraft to test technology it helped develop or recommended to the U.S. Forest Service, including a system to send sensor data to decision makers on the ground in near real time.Credit: NASA It’s not easy to predict the path of forest fires—a lot depends on constantly changing factors like wind. But it is crucial to be as accurate as possible because the lives, homes, and businesses of the tens of thousands of people living and working in fire-prone areas depend on the reliability of these predictions. Sensors mounted on airplanes or drones that provide a picture of the fire from above are an important tool, and that’s where NASA comes in.
In partnership with the U.S. Forest Service, local and state firefighting agencies, and the Bureau of Land Management, NASA plays a pivotal role in battling infernos. The agency’s extensive experience and technical expertise in remote sensing technology have significantly improved the speed and accuracy of information relayed to firefighting decision-makers.
According to Don Sullivan, who specialized in information technology design at the time, the Airborne Science Program at NASA’s Ames Research Center in Silicon Valley, California, was integral to that effort.
In the 1990s, NASA began a project to adapt uncrewed aircraft for environmental research. The researchers at Ames wanted to ensure the technology would be useful to the broadest possible spectrum of potential end users. One concept tested during the project was sending data in real-time to the ground via communications links installed on the aircraft.
That link sent data faster and to multiple recipients at once—not just the team on the fire front line, but also the commanders organizing the teams and decision makers looking at the big picture across the entire region throughout the fire season, explained Sullivan.
For the Forest Service, this was a much-needed upgrade to the original system on their crewed jets: rolling up a printout and later thumb drives with thermal sensor data placed into a plastic tube attached to a parachute and dropped out of the airplane. NASA’s remotely piloted aircraft called Ikhana tested the technology, and it’s still used by the agency to collect data on wildfires.
Since the introduction of this technology, wildfires have gotten bigger, burn hotter, and set new records every year. But in California in 2008, this technology helped fight what was then the worst fire season on record. A NASA test flight using a data downlink system provided updated information to the incident managers that was crucial in determining where to send firefighting resources and whether a full evacuation of the town of Paradise was needed.
Without that timely information, said Sullivan, “there likely would have been injuries and certainly property damage that was worse than it turned out to be.”
