As humanity prepares to return to the lunar surface, Aaisha Ali is behind the scenes ensuring mission readiness for astronauts set to orbit the Moon during Artemis II.
Ali is the Artemis ground control flight lead at NASA’s Johnson Space Center in Houston. She makes sure her team has the resources needed for the next giant leap to the Moon and beyond.

Artemis Ground Control Flight Lead
Ali received a bachelor’s degree in biology from Texas A&M University at Galveston before beginning a career as a marine biologist. Her curiosity about science and communication eventually led her from studying marine life to sharing NASA’s mission with the public. With a robust skill set that includes public relations, media relations, and strategic communications, she went on to work at Space Center Houston and later at Johnson on the protocol and digital imagery teams.
Today, Ali leads the ground control team supporting Artemis II, ensuring that systems, simulations, and procedures are ready for the mission. Her role includes developing flight rules, finalizing operations plans and leading training sessions – known as “network sims” – that prepare her team to respond quickly and effectively.
“Because I’ve had a multifaceted career path, it has given me a different outlook,” she said. “Diversity of mindsets helps us approach problems. Sometimes a different angle is exactly what we need.”

Her perspective was also shaped by visits to her grandmother in the Caribbean as a child. “She lived in the tropical forest in a small village in Trinidad,” Ali said. “I was fortunate enough to spend summers on the island and experience a different way of life, which has helped me grow into the person I am today.”
Communication, she explained, is just as critical as technical expertise. “When we report to the flight director, we are the experts in our system. But we have to be clear and concise. You don’t get a lot of time on the flight loop to explain.”
That clarity, humility, and sense of teamwork are values Ali says have shaped her journey.
Aaisha Ali participates in a public affairs event at Ellington Field Joint Reserve Base in Houston in 2005. We don’t do it by ourselves. Everyone — from our engineers to custodial staff to cafeteria workers — plays a role in getting us to the Moon. NASA is for the world. And it takes all of us.

Looking ahead, Ali is especially passionate about inspiring the Artemis Generation — those who will one day explore the Moon and Mars. She often shares advice with her nieces and nephews, including one determined nephew who has dreamed of becoming an astronaut since age 7.
“Do what you love, and NASA will find a place for you,” she said. “NASA is a big place. If you love the law, we have lawyers. If you love art, science, or technology, there’s a place for you. Passion is what we’re looking for.”
Aaisha Ali at Walt Disney World in Orlando, Florida. In her free time, Ali enjoys photography and connecting with nature by camping and visiting national parks. She also loves planning trips to Walt Disney World, meeting new people, experiencing different cultures, and learning new things.
Even as her days are packed with simulations and mission prep, Ali knows landing astronauts on the lunar surface for Artemis III is not far behind.
“There’s a lot of uphill left to climb,” she said. “But we’re ready.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Since launching in 2023, NASA’s Tropospheric Emissions: Monitoring of Pollution mission, or TEMPO, has been measuring the quality of the air we breathe from 22,000 miles above the ground. June 19 marked the successful completion of TEMPO’s 20-month-long initial prime mission, and based on the quality of measurements to date, the mission has been extended through at least September 2026. The TEMPO mission is NASA’s first to use a spectrometer to gather hourly air quality data continuously over North America during daytime hours. It can see details down to just a few square miles, a significant advancement over previous satellites.
“NASA satellites have a long history of missions lasting well beyond the primary mission timeline. While TEMPO has completed its primary mission, the life for TEMPO is far from over,” said Laura Judd, research physical scientist and TEMPO science team member at NASA’s Langley Research Center in Hampton, Virginia. “It is a big jump going from once-daily images prior to this mission to hourly data. We are continually learning how to use this data to interpret how emissions change over time and how to track anomalous events, such as smoggy days in cities or the transport of wildfire smoke.”

By measuring nitrogen dioxide (NO2) and formaldehyde (HCHO), TEMPO can derive the presence of near-surface ozone. On Aug. 2, 2024 over Houston, TEMPO observed exceptionally high ozone levels in the area. On the left, NO2 builds up in the atmosphere over the city and over the Houston Ship Channel. On the right, formaldehyde levels are seen reaching a peak in the early afternoon. Formaldehyde is largely formed through the oxidation of hydrocarbons, an ingredient of ozone production, such as those that can be emitted by petrochemical facilities found in the Houston Ship Channel. Trent Schindler/NASA's Scientific Visualization Studio When air quality is altered by smog, wildfire smoke, dust, or emissions from vehicle traffic and power plants, TEMPO detects the trace gases that come with those effects. These include nitrogen dioxide, ozone, and formaldehyde in the troposphere, the lowest layer of Earth’s atmosphere.
“A major breakthrough during the primary mission has been the successful test of data delivery in under three hours with the help of NASA’s Satellite Needs Working Group. This information empowers decision-makers and first responders to issue timely air quality warnings and help the public reduce outdoor exposure during times of higher pollution,” said Hazem Mahmoud, lead data scientist at NASA’s Atmospheric Science Data Center located at Langley Research Center.

TEMPO data is archived and distributed freely through the Atmospheric Science Data Center. “The TEMPO mission has set a groundbreaking record as the first mission to surpass two petabytes, or 2 million gigabytes, of data downloads within a single year,” said Mahmoud. “With over 800 unique users, the substantial demand for TEMPO’s data underscores its critical role and the immense value it provides to the scientific community and beyond.” Air quality forecasters, atmospheric scientists, and health researchers make up the bulk of the data users so far.

On April 14, strong winds triggered the formation of a huge dust storm in the U.S. central plains and fueled the ignition of grassland fires in Oklahoma. On the left, the NO2 plumes originating from the grassland fires are tracked hour-by-hour by TEMPO. Smoke can be discerned from dust as a source since dust is not a source of NO2. The animation on the right shows the ultraviolet (UV) aerosol index, which indicates particulates in the atmosphere that absorb UV light, such as dust and smoke. Trent Schindler/NASA's Scientific Visualization Studio The TEMPO mission is a collaboration between NASA and the Smithsonian Astrophysical Observatory, whose Center for Astrophysics Harvard & Smithsonian oversees daily operations of the TEMPO instrument and produces data products through its Instrument Operations Center.
Datasets from TEMPO will be expanded through collaborations with partner agencies like the National Oceanic and Atmospheric Administration (NOAA), which is deriving aerosol products that can distinguish between smoke and dust particles and offer insights into their altitude and concentration.

On May 5, TEMPO measured NO2 emissions over the Twin Cities in the center of Minnesota during morning rush hour. The NO2 increases seen mid-day through the early evening hours are illustrated by the red and black shaded areas at the Red River Valley along the North Dakota state line. These levels are driven by emissions from the soils in agriculturally rich areas. Agricultural soil emissions are influenced by environmental factors like temperature and moisture as well as fertilizer application. Small fires and enhancements from mining activities can also be seen popping up across the region through the afternoon.Trent Schindler/NASA's Scientific Visualization Studio “These datasets are being used to inform the public of rush-hour pollution, air quality alerts, and the movement of smoke from forest fires,” said Xiong Liu, TEMPO’s principal investigator at the Center for Astrophysics Harvard & Smithsonian. “The library will soon grow with the important addition of aerosol products. Users will be able to use these expanded TEMPO products for air quality monitoring, improving forecast models, deriving pollutant amounts in emissions and many other science applications.”
The TEMPO mission detects and highlights movement of smoke originating from fires burning in Manitoba on June 2. Seen in purple hues are observations made by TEMPO in the ultraviolet spectrum compared to Advanced Baseline Imagers (ABIs) on NOAA’s GOES-R series of weather satellites that do not have the needed spectral coverage. The NOAA GOES-R data paired with NASA’s TEMPO data enhance state and local agencies’ ability to provide near-real-time smoke and dust impacts in local air quality forecasts.NOAA/NESDIS/Center for Satellite Applications and Research “The TEMPO data validation has truly been a community effort with over 20 agencies at the federal and international level, as well as a community of over 200 scientists at research and academic institutions,” Judd added. “I look forward to seeing how TEMPO data will help close knowledge gaps about the timing, sources, and evolution of air pollution from this unprecedented space-based view.”
An agency review will take place in the fall to assess TEMPO’s achievements and extended mission goals and identify lessons learned that can be applied to future missions.
The TEMPO mission is part of NASA’s Earth Venture Instrument program, which includes small, targeted science investigations designed to complement NASA’s larger research missions. The instrument also forms part of a virtual constellation of air quality monitors for the Northern Hemisphere which includes South Korea’s Geostationary Environment Monitoring Spectrometer and ESA’s (European Space Agency) Sentinel-4 satellite. TEMPO was built by BAE Systems Inc., Space & Mission Systems (formerly Ball Aerospace). It flies onboard the Intelsat 40e satellite built by Maxar Technologies. The TEMPO Instrument Operations Center and the Science Data Processing Center are operated by the Smithsonian Astrophysical Observatory, part of the Center for Astrophysics | Harvard & Smithsonian in Cambridge.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Swept Wing Flow Test model, known as SWiFT, with pressure sensitive paint applied, sports a pink glow under ultraviolet lights while tested during 2023 in a NASA wind tunnel at Langley Research Center in Virginia.NASA / Dave Bowman Many of us grew up using paint-by-number sets to create beautiful color pictures.
For years now, NASA engineers studying aircraft and rocket designs in wind tunnels have flipped that childhood pastime, using computers to generate images from “numbers-by-paint” – pressure sensitive paint (PSP), that is.
Now, advances in the use of high-speed cameras, supercomputers, and even more sensitive PSP have made this numbers-by-paint process 10,000 times faster while creating engineering visuals with 1,000 times higher resolution.
So, what’s the big difference exactly between the “old” capability in use at NASA for more than a decade and the “new?”
“The key is found by adding a single word in front of PSP, namely ‘unsteady’ pressure sensitive paint, or uPSP,” said E. Lara Lash, an aerospace engineer from NASA’s Ames Research Center in California’s Silicon Valley.
With PSP, NASA researchers study the large-scale effects of relatively smooth air flowing over the wings and body of aircraft. Now with uPSP, they are able to see in finer detail what happens when more turbulent air is present – faster and better than ever before.
In some cases with the new capability, researchers can get their hands on the wind tunnel data they’re looking for within 20 minutes. That’s quick enough to allow engineers to adjust their testing in real time.
Usually, researchers record wind tunnel data and then take it back to their labs to decipher days or weeks later. If they find they need more data, it can take additional weeks or even months to wait in line for another turn in the wind tunnel.
“The result of these improvements provides a data product that is immediately useful to aerodynamic engineers, structural engineers, or engineers from other disciplines,” Lash said.
Robert Pearce, NASA’s associate administrator for aeronautics, who recently saw a demonstration of uPSP-generated data displayed at Ames, hailed the new tool as a national asset that will be available to researchers all over the country.
“It’s a unique NASA innovation that isn’t offered anywhere else,” Pearce said. “It will help us maintain NASA’s world leadership in wind tunnel capabilities.”

With both PSP and uPSP, a unique paint is applied to scale models of aircraft or rockets, which are mounted in wind tunnels equipped with specific types of lights and cameras.
When illuminated during tests, the paint’s color brightness changes depending on the levels of pressure the model experiences as currents of air rush by. Darker shades mean higher pressure; lighter shades mean lower pressure.
Cameras capture the brightness intensity and a supercomputer turns that information into a set of numbers representing pressure values, which are made available to engineers to study and glean what truths they can about the vehicle design’s structural integrity.
“Aerodynamic forces can vibrate different parts of the vehicle to different degrees,” Lash said. “Vibrations could damage what the vehicle is carrying or can even lead to the vehicle tearing itself apart. The data we get through this process can help us prevent that.”
Traditionally, pressure readings are taken using sensors connected to little plastic tubes strung through a model’s interior and poking up through small holes in key places, such as along the surface of a wing or the fuselage.
Each point provides a single pressure reading. Engineers must use mathematical models to estimate the pressure values between the individual sensors.
With PSP, there is no need to estimate the numbers. Because the paint covers the entire model, its brightness as seen by the cameras reveals the pressure values over the whole surface.

The introduction, testing, and availability of uPSP is the result of a successful five-year-long effort, begun in 2019, in which researchers challenged themselves to significantly improve the PSP’s capability with its associated cameras and computers.
The NASA team’s desire was to develop and demonstrate a better process of acquiring, processing, and visualizing data using a properly equipped wind tunnel and supercomputer, then make the tool available at NASA wind tunnels across the country.
The focus during a capability challenge was on NASA’s Unitary Plan Facility’s 11-foot transonic wind tunnel, which the team connected to the nearby NASA Advanced Supercomputing Facility, both located at Ames.
Inside the wind tunnel, a scale model of NASA’s Space Launch System rocket served as the primary test subject during the challenge period.
Now that the agency has completed its Artemis I uncrewed lunar flight test mission, researchers can match the flight-recorded data with the wind tunnel data to see how well reality and predictions compare.
With the capability challenge officially completed at the end of 2024, the uPSP team is planning to deploy it to other wind tunnels and engage with potential users with interests in aeronautics or spaceflight.
“This is a NASA capability that we have, not only for use within the agency, but one that we can offer industry, academia, and other government agencies to come in and do research using these new tools,” Lash said.
NASA’s Aerosciences Evaluation and Test Capabilities portfolio office, an organization managed under the agency’s Aeronautics Research Mission Directorate, oversaw the development of the uPSP capability.

An unexpectedly strong solar storm rocked our planet on April 23, 2023, sparking auroras as far south as southern Texas in the U.S. and taking the world by surprise.
Two days earlier, the Sun blasted a coronal mass ejection (CME) — a cloud of energetic particles, magnetic fields, and solar material — toward Earth. Space scientists took notice, expecting it could cause disruptions to Earth’s magnetic field, known as a geomagnetic storm. But the CME wasn’t especially fast or massive, and it was preceded by a relatively weak solar flare, suggesting the storm would be minor. But it became severe.
Using NASA heliophysics missions, new studies of this storm and others are helping scientists learn why some CMEs have more intense effects — and better predict the impacts of future solar eruptions on our lives.
During the night of April 23 to 24, 2023, a geomagnetic storm produced auroras that were witnessed as far south as Arizona, Arkansas, and Texas in the U.S. This photo shows green aurora shimmering over Larimore, North Dakota, in the early morning of April 24. Copyright Elan Azriel, used with permission Why Was This Storm So Intense?
A paper published in the Astrophysical Journal on March 31 suggests the CME’s orientation relative to Earth likely caused the April 2023 storm to become surprisingly strong.
The researchers gathered observations from five heliophysics spacecraft across the inner solar system to study the CME in detail as it emerged from the Sun and traveled to Earth.
They noticed a large coronal hole near the CME’s birthplace. Coronal holes are areas where the solar wind — a stream of particles flowing from the Sun — floods outward at higher than normal speeds.
“The fast solar wind coming from this coronal hole acted like an air current, nudging the CME away from its original straight-line path and pushing it closer to Earth’s orbital plane,” said the paper’s lead author, Evangelos Paouris of the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. “In addition to this deflection, the CME also rotated slightly.”
Paouris says this turned the CME’s magnetic fields opposite to Earth’s magnetic field and held them there — allowing more of the Sun’s energy to pour into Earth’s environment and intensifying the storm.
The strength of the April 2023 geomagnetic storm was a surprise in part because the coronal mass ejection (CME) that produced it followed a relatively weak solar flare, seen as the bright area to the lower right of center in this extreme ultraviolet image of the Sun from NASA’s Solar Dynamics Observatory. The CMEs that produce severe geomagnetic storms are typically preceded by stronger flares. However, a team of scientists think fast solar wind from a coronal hole (the dark area below the flare in this image) helped rotate the CME and made it more potent when it struck Earth. NASA/SDO Cool Thermosphere
Meanwhile, NASA’s GOLD (Global-scale Observations of Limb and Disk) mission revealed another unexpected consequence of the April 2023 storm at Earth.
Before, during, and after the storm, GOLD studied the temperature in the middle thermosphere, a part of Earth’s upper atmosphere about 85 to 120 miles overhead. During the storm, temperatures increased throughout GOLD’s wide field of view over the Americas. But surprisingly, after the storm, temperatures dropped about 90 to 198 degrees Fahrenheit lower than they were before the storm (from about 980 to 1,070 degrees Fahrenheit before the storm to 870 to 980 degrees Fahrenheit afterward).
“Our measurement is the first to show widespread cooling in the middle thermosphere after a strong storm,” said Xuguang Cai of the University of Colorado, Boulder, lead author of a paper about GOLD’s observations published in the journal JGR Space Physics on April 15, 2025.
The thermosphere’s temperature is important, because it affects how much drag Earth-orbiting satellites and space debris experience.
“When the thermosphere cools, it contracts and becomes less dense at satellite altitudes, reducing drag,” Cai said. “This can cause satellites and space debris to stay in orbit longer than expected, increasing the risk of collisions. Understanding how geomagnetic storms and solar activity affect Earth’s upper atmosphere helps protect technologies we all rely on — like GPS, satellites, and radio communications.”
Predicting When Storms Strike
To predict when a CME will trigger a geomagnetic storm, or be “geoeffective,” some scientists are combining observations with machine learning. A paper published last November in the journal Solar Physics describes one such approach called GeoCME.
Machine learning is a type of artificial intelligence in which a computer algorithm learns from data to identify patterns, then uses those patterns to make decisions or predictions.
Scientists trained GeoCME by giving it images from the NASA/ESA (European Space Agency) SOHO (Solar and Heliospheric Observatory) spacecraft of different CMEs that reached Earth along with SOHO images of the Sun before, during, and after each CME. They then told the model whether each CME produced a geomagnetic storm.
Then, when it was given images from three different science instruments on SOHO, the model’s predictions were highly accurate. Out of 21 geoeffective CMEs, the model correctly predicted all 21 of them; of 7 non-geoeffective ones, it correctly predicted 5 of them.
“The algorithm shows promise,” said heliophysicist Jack Ireland of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, who was not involved in the study. “Understanding if a CME will be geoeffective or not can help us protect infrastructure in space and technological systems on Earth. This paper shows machine learning approaches to predicting geoeffective CMEs are feasible.”
The white cloud expanding outward in this image sequence is a coronal mass ejection (CME) that erupted from the Sun on April 21, 2023. Two days later, the CME struck Earth and produced a surprisingly strong geomagnetic storm. The images in this sequence are from a coronagraph on the NASA/ESA (European Space Agency) SOHO (Solar and Heliospheric Observatory) spacecraft. The coronagraph uses a disk to cover the Sun and reveal fainter details around it. The Sun’s location and size are indicated by a small white circle. The planet Jupiter appears as a bright dot on the far right. NASA/ESA/SOHO Earlier Warnings
During a severe geomagnetic storm in May 2024 — the strongest to rattle Earth in over 20 years — NASA’s STEREO (Solar Terrestrial Relations Observatory) measured the magnetic field structure of CMEs as they passed by.
When a CME headed for Earth hits a spacecraft first, that spacecraft can often measure the CME and its magnetic field directly, helping scientists determine how strong the geomagnetic storm will be at Earth. Typically, the first spacecraft to get hit are one million miles from Earth toward the Sun at a place called Lagrange Point 1 (L1), giving us only 10 to 60 minutes advanced warning.
By chance, during the May 2024 storm, when several CMEs erupted from the Sun and merged on their way to Earth, NASA’s STEREO-A spacecraft happened to be between us and the Sun, about 4 million miles closer to the Sun than L1.
A paper published March 17, 2025, in the journal Space Weather reports that if STEREO-A had served as a CME sentinel, it could have provided an accurate prediction of the resulting storm’s strength 2 hours and 34 minutes earlier than a spacecraft could at L1.
According to the paper’s lead author, Eva Weiler of the Austrian Space Weather Office in Graz, “No other Earth-directed superstorm has ever been observed by a spacecraft positioned closer to the Sun than L1.”

Communicating in space usually relies on radio waves, but NASA is exploring laser, or optical, communications, which can send data 10 to 100 times faster to the ground. Instead of radio signals, these systems use infrared light to transmit high-definition video, picture, voice, and science data across vast distances in less time. NASA has proven laser communications during previous technology demonstrations, but Artemis II will be the first crewed mission to attempt using lasers to transmit data from deep space.
To support this effort, researchers working on the agency’s Real Time Optical Receiver (RealTOR) project have developed a cost-effective laser transceiver using commercial-off-the-shelf parts. Earlier this year, NASA Glenn engineers built and tested a replica of the system at the center’s Aerospace Communications Facility, and they are now working with ANU to build a system with the same hardware models to prepare for the university’s Artemis II laser communications demo.
“Australia’s upcoming lunar experiment could showcase the capability, affordability, and reproducibility of the deep space receiver engineered by Glenn,” said Jennifer Downey, co-principal investigator for the RealTOR project at NASA Glenn. “It’s an important step in proving the feasibility of using commercial parts to develop accessible technologies for sustainable exploration beyond Earth.”
During Artemis II, which is scheduled for early 2026, NASA will fly an optical communications system aboard the Orion spacecraft, which will test using lasers to send data across the cosmos. During the mission, NASA will attempt to transmit recorded 4K ultra-high-definition video, flight procedures, pictures, science data, and voice communications from the Moon to Earth.

This ground station will serve as a test location for the new transceiver design and will not be one of the mission’s primary ground stations. If the test is successful, it will prove that commercial parts can be used to build affordable, scalable space communication systems for future missions to the Moon, Mars, and beyond.
“Engaging with The Australian National University to expand commercial laser communications offerings across the world will further demonstrate how this advanced satellite communications capability is ready to support the agency’s networks and missions as we set our sights on deep space exploration,” said Marie Piasecki, technology portfolio manager for NASA’s Space Communications and Navigation (SCaN) Program.
As NASA continues to investigate the feasibility of using commercial parts to engineer ground stations, Glenn researchers will continue to provide critical support in preparation for Australia’s demonstration.
Strong global partnerships advance technology breakthroughs and are instrumental as NASA expands humanity’s reach from the Moon to Mars, while fueling innovations that improve life on Earth. Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

These include the LCOT (Low-Cost Optical Terminal) project, the Laser Communications Relay Demonstration, and more. NASA Glenn manages the project under the direction of agency’s SCaN Program at NASA Headquarters in Washington.
The Australian National University’s demonstration is supported by the Australian Space Agency Moon to Mars Demonstrator Mission Grant program, which has facilitated operational capability for the Australian Deep Space Optical Ground Station Network.
