Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA and partners from Aerostar and AeroVironment discuss a simulation of a high-altitude air traffic management system for vehicles flying 60,000 feet and above in the Airspace Operations Lab (AOL) at NASA’s Ames Research Center in California’s Silicon Valley.NASA/Don Richey NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes. This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as an Upper-Class E traffic management, or ETM.
There is currently no traffic management system or set of regulations in place for aircraft operating 60,000 feet and above. There hasn’t been a need for a robust traffic management system in this airspace until recently. That’s because commercial aircraft couldn’t function at such high altitudes due to engine constraints.
However, recent advancements in aircraft design, power, and propulsion systems are making it possible for high altitude long endurance vehicles — such as balloons, airships, and solar aircraft — to coast miles above our heads, providing radio relay for disaster response, collecting atmospheric data, and more.
But before these aircraft can regularly take to the skies, operators must find a way to manage their operations without overburdening air traffic infrastructure and personnel.
NASA partners from Aerostar and AeroVironment discuss a simulation of the ATM-X E Traffic Management (ETM) system for vehicles flying 60,000 feet and above in the Airspace Operations Lab (AOL) at NASA’s Ames Research Center in California’s Silicon Valley. “We are working to safely expand high-altitude missions far beyond what is currently possible,” said Kenneth Freeman, a subproject manager for this effort at NASA’s Ames Research Center in California’s Silicon Valley. “With routine, remotely piloted high-altitude operations, we have the opportunity to improve our understanding of the planet through more detailed tracking of climate change, provide internet coverage in underserved areas, advance supersonic flight research, and more.”
Current high-altitude traffic management is processed manually and on a case-by-case basis. Operators must contact air traffic control to gain access to a portion of the Class E airspace. During these operations, no other aircraft can enter this high-altitude airspace. This method will not accommodate the growing demand for high-altitude missions, according to NASA researchers.
To address this challenge, NASA and its partners have developed an ETM traffic management system that allows aircraft to autonomously share location and flight plans, enabling aircraft to stay safely separated.
During the recent traffic management simulation in the Airspace Operations Laboratory at Ames, data from multiple air vehicles was displayed across dozens of traffic control monitors and shared with partner computers off site. This included aircraft location, health, flight plans and more. Researchers studied interactions between a slow fixed-wing vehicle from AeroVironment and a high-altitude balloon from Aerostar operating at stratospheric heights. Each aircraft, connected to the ETM traffic management system for high altitude, shared location and flight plans with surrounding aircraft.
This digital information sharing allowed Aerostar and AeroVironment high-altitude vehicle operators to coordinate and deconflict with each other in the same simulated airspace, without having to gain approval from air traffic control. Because of this, aircraft operators were able to achieve their objectives, including wireless communication relay.
This simulation represents the first time a traffic management system was able to safely manage a diverse set of high-altitude aircraft operations in the same simulated airspace. Next, NASA researchers will work with partners to further validate this system through a variety of real flight tests with high-altitude aircraft in a shared airspace.
The Upper-Class E traffic management concept was developed in coordination with the Federal Aviation Administration and high-altitude platform industry partners, under NASA’s National Airspace System Exploratory Concepts and Technologies subproject led out of Ames.

NASA, NOAA: Sun Reaches Maximum Phase in 11-Year Solar Cycle
In a teleconference with reporters on Tuesday, representatives from NASA, the National Oceanic and Atmospheric Administration (NOAA), and the international Solar Cycle Prediction Panel announced that the Sun has reached its solar maximum period, which could continue for the next year.
The solar cycle is a natural cycle the Sun goes through as it transitions between low and high magnetic activity. Roughly every 11 years, at the height of the solar cycle, the Sun’s magnetic poles flip — on Earth, that’d be like the North and South poles swapping places every decade — and the Sun transitions from being calm to an active and stormy state.
Visible light images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum (left, Dec. 2019) versus solar maximum (right, May 2024). During solar minimum, the Sun is often spotless. Sunspots are associated with solar activity and are used to track solar cycle progress. For these images and more relating to solar maximum, visit https://svs.gsfc.nasa.gov/14683.
NASA/SDO Images from NASA’s Solar Dynamics Observatory highlight the appearance of the Sun at solar minimum (left, December 2019) versus solar maximum (right, May 2024). These images are in the 171-angstrom wavelength of extreme ultraviolet light, which reveals the active regions on the Sun that are more common during solar maximum. For these images and more relating to solar maximum, visit https://svs.gsfc.nasa.gov/14683.

NASA and NOAA track sunspots to determine and predict the progress of the solar cycle — and ultimately, solar activity. Sunspots are cooler regions on the Sun caused by a concentration of magnetic field lines. Sunspots are the visible component of active regions, areas of intense and complex magnetic fields on the Sun that are the source of solar eruptions.
“During solar maximum, the number of sunspots, and therefore, the amount of solar activity, increases,” said Jamie Favors, director, Space Weather Program at NASA Headquarters in Washington. “This increase in activity provides an exciting opportunity to learn about our closest star — but also causes real effects at Earth and throughout our solar system.”
The solar cycle is the natural cycle of the Sun as it transitions between low and high activity. During the most active part of the cycle, known as solar maximum, the Sun can unleash immense explosions of light, energy, and solar radiation — all of which create conditions known as space weather. Space weather can affect satellites and astronauts in space, as well as communications systems — such as radio and GPS — and power grids on Earth.
Credits: Beth Anthony/NASA Solar activity strongly influences conditions in space known as space weather. This can affect satellites and astronauts in space, as well as communications and navigation systems — such as radio and GPS — and power grids on Earth. When the Sun is most active, space weather events become more frequent. Solar activity has led to increased aurora visibility and impacts on satellites and infrastructure in recent months.
During May 2024, a barrage of large solar flares and coronal mass ejections (CMEs) launched clouds of charged particles and magnetic fields toward Earth, creating the strongest geomagnetic storm at Earth in two decades — and possibly among the strongest displays of auroras on record in the past 500 years.
May 3–May 9, 2024, NASA’s Solar Dynamics Observatory observed 82 notable solar flares. The flares came mainly from two active regions on the Sun called AR 13663 and AR 13664. This video highlights all flares classified at M5 or higher with nine categorized as X-class solar flares.
Credit: NASA “This announcement doesn’t mean that this is the peak of solar activity we’ll see this solar cycle,” said Elsayed Talaat, director of space weather operations at NOAA. “While the Sun has reached the solar maximum period, the month that solar activity peaks on the Sun will not be identified for months or years.”
Scientists will not be able to determine the exact peak of this solar maximum period for many months because it’s only identifiable after they’ve tracked a consistent decline in solar activity after that peak. However, scientists have identified that the last two years on the Sun have been part of this active phase of the solar cycle, due to the consistently high number of sunspots during this period. Scientists anticipate that the maximum phase will last another year or so before the Sun enters the declining phase, which leads back to solar minimum. Since 1989, the Solar Cycle Prediction Panel — an international panel of experts sponsored by NASA and NOAA — has worked together to make their prediction for the next solar cycle.
Solar cycles have been tracked by astronomers since Galileo first observed sunspots in the 1600s. Each solar cycle is different — some cycles peak for larger and shorter amounts of time, and others have smaller peaks that last longer.
Sunspot number over the previous 24 solar cycles. Scientists use sunspots to track solar cycle progress; the dark spots are associated with solar activity, often as the origins for giant explosions — such as solar flares or coronal mass ejections — which can spew light, energy, and solar material out into space. For these images and more relating to solar maximum, visit https://svs.gsfc.nasa.gov/14683.
NOAA’s Space Weather Prediction Center “Solar Cycle 25 sunspot activity has slightly exceeded expectations,” said Lisa Upton, co-chair of the Solar Cycle Prediction Panel and lead scientist at Southwest Research Institute in San Antonio, Texas. “However, despite seeing a few large storms, they aren’t larger than what we might expect during the maximum phase of the cycle.”
The most powerful flare of the solar cycle so far was an X9.0 on Oct. 3 (X-class denotes the most intense flares, while the number provides more information about its strength).
NOAA anticipates additional solar and geomagnetic storms during the current solar maximum period, leading to opportunities to spot auroras over the next several months, as well as potential technology impacts. Additionally, though less frequent, scientists often see fairly significant storms during the declining phase of the solar cycle.

NOAA’s Space Weather Prediction Center NASA and NOAA are preparing for the future of space weather research and prediction. In December 2024, NASA’s Parker Solar Probe mission will make its closest-ever approach to the Sun, beating its own record of closest human-made object to the Sun. This will be the first of three planned approaches for Parker at this distance, helping researchers to understand space weather right at the source.
NASA is launching several missions over the next year that will help us better understand space weather and its impacts across the solar system.
Space weather predictions are critical for supporting the spacecraft and astronauts of NASA’s Artemis campaign. Surveying this space environment is a vital part of understanding and mitigating astronaut exposure to space radiation.
NASA works as a research arm of the nation’s space weather effort. To see how space weather can affect Earth, please visit NOAA’s Space Weather Prediction Center, the U.S. government’s official source for space weather forecasts, watches, warnings, and alerts.
