Preparations for Next Moonwalk Simulations Underway (and Underwater)
Artist’s concept of a future airliner based on the NASA Advanced Aircraft Concepts for Environmental Sustainability 2050 submission from awardee Electra. The team’s project focuses on electric propulsion, integrated aircraft technologies, and vehicle design.Electra Picture yourself at an airport a few decades from now. What does your airliner look like? It’s more efficient, with lower emissions than today’s aircraft – what kinds of designs or technology make that possible? NASA is working to answer those questions by commissioning five new design studies looking to push the boundaries of possibility for sustainable aircraft.
Through NASA’s Advanced Aircraft Concepts for Environmental Sustainability (AACES) 2050 initiative, the agency asked industry and academia to come up with studies looking at aircraft concepts, key technologies, and designs that could offer the transformative solutions needed to secure commercial aviation’s sustainable future by 2050. NASA issued five awards, worth a total of $11.5 million, to four companies and one university. These new NASA-funded studies will help the agency identify and select promising aircraft concepts and technologies for further investigations.

The team’s project focuses on exploring scenarios and technologies based on an aircraft concept the institute has developed, known as ATH2ENA.Georgia Institute of Technology “Through initiatives like AACES, NASA is positioned to harness a broad set of perspectives about how to further increase aircraft efficiency, reduce aviation’s environmental impact and enhance U.S. technological competitiveness in the 2040s, 2050s, and beyond,” said Bob Pearce, NASA associate administrator for the Aeronautics Research Mission Directorate. “As a leader in U.S. sustainable aviation research and development, these awards are one example of how we bring together the best ideas and most innovative concepts from the private sector, academia, research agencies, and other stakeholders to pioneer the future of aviation.”
For decades, NASA has connected government agencies, industry, and academia to develop sustainable aviation technologies. In 2021, NASA launched its Sustainable Flight National Partnership, focused on technologies that could be incorporated into aircraft by the 2030s. The partnership’s research and development led to current NASA work including the experimental X-66 Sustainable Flight Demonstrator aircraft, its Electrified Powertrain Flight Demonstration project, and the development of more efficient engine cores and processes for the rapid manufacturing of lightweight composite materials.

The kinds of partnerships NASA develops through SFNP and AACES are critical for the agency to support the U.S. goal of net-zero aviation emissions by 2050 and to help put aviation on a path toward energy-resilience.
“The AACES 2050 solicitation drew significant interest from the aviation community and as a result the award process was highly competitive,” said Nateri Madavan, director for NASA’s Advanced Air Vehicles Program. “The proposals selected come from a diverse set of organizations that will provide exciting and wide-ranging explorations of the scenarios, technologies, and aircraft concepts that will advance aviation towards its transformative sustainability goals.”

NASA expects the awardees to complete their studies by mid-2026. The new awardee institutions are:
Aurora Flight Sciences, a Boeing Company, whose team will perform a comprehensive, “open-aperture” exploration of technologies and aircraft concepts for the 2050 timeframe. This will include examining new alternative aviation fuels, propulsion systems, aerodynamic technologies, and aircraft configurations along with other technology areas that arise throughout the study. The Electra-led team will explore extending Electra’s novel distributed electric propulsion and its unique aerodynamic design capabilities to develop innovative wing and fuselage integrations that deliver sustainable aviation focused on enabling community-friendly emission reduction, noise reduction, and improved air travel access. The company’s existing small aircraft prototype has been flying for over a year, demonstrating Electra’s technology that aims to transform air travel with reduced environmental impact and improved operational efficiency. Georgia Institute of Technology will perform a comprehensive exploration of sustainability technologies, including alternative fuels, propulsion systems, and aircraft configurations. The institute’s team will then explore new aircraft concepts incorporating the selected technologies with their Advanced Technology Hydrogen Electric Novel Aircraft (ATH2ENA) as a starting point. JetZero will explore technologies that enable cryogenic, liquid hydrogen to be used as a fuel for commercial aviation to reduce greenhouse gas emissions. These technologies will be evaluated on both tube-and wing and JetZero’s blended wing body – an airplane shape that provides more options for larger hydrogen fuel tanks within the aircraft. Pratt and Whitney a division of RTX Corporation, will explore a broad suite of commercial aviation propulsion technologies targeting thermal and propulsive efficiency improvements to reduce fuel consumption and greenhouse gas emissions. The Pratt & Whitney team will then down-select high-priority and alternative propulsion concepts for potential integration studies with various airframe concepts for aircraft in 2050 and beyond.

Looking Back on Looking Up: The 2024 Total Solar Eclipse
Credit: NASA’s Glenn Research Center (GRC) Introduction
First as a bite, then a half Moon, until crescent-shaped shadows dance through the leaves and the temperature begins to drop – a total solar eclipse can be felt growing in the atmosphere. As the sky darkens in the few minutes before totality, the sounds of animals begin to dissipate along with the vibrancy of red and orange hues, and we enter the mesopic zone, or twilight vision. All is quiet in these cold, silvery-blue moments, until the Moon lines up perfectly with the Sun from our viewpoint on Earth – an odd quirk of the Moon–Earth system, and an occurrence that does not exist elsewhere in the solar system.
Millions of people gazed up at the sky on April 8, 2024, as a total solar eclipse darkened the skies across a thin ribbon of North America – spanning Mexico’s Pacific coast to the Atlantic coast of Newfoundland, Canada – see Figure 1.
Figure 1. A total solar eclipse was visible along a narrow track stretching from Texas to Maine on April 8, 2024. A partial eclipse was visible throughout all 48 contiguous U.S. states. Figure credit: NASA Scientific Visualization Studio A pearly, iridescent halo lined the perimeter of the Moon as it crossed in front of the Sun, revealing the Sun’s corona – see Photo 1. Solar prominences – bright features made of plasma flowing outwards through tangled structures of magnetic fields along the Sun’s surface – were observable as reddish-pink dots rising from the edges of the eclipsed Sun – see Photo 2.

Over 400 NASA staff took up positions along the path of totality, hosting various events to engage the public in outreach activities spanning the scope of NASA Science. NASA staff hosted 14 “SunSpot” locations across 7 states (Texas, Arkansas, Ohio, Indiana, Pennsylvania, New York, and Maine), including 224 NASA engagement and Science Activation events. As an example, Zoe Jenkins [NASA Headquarters/Arctic Slope Regional Corporation (ASRC) Federal—Graphic Designer] was stationed in Maine to view the eclipse –see Photos 3–4. More information about events at these SunSpots is available at the eclipse website. The Science Activation Program furthered NASA’s message, reaching all 50 states through public events by sharing information and providing professional development programming for educators. (To learn more about NASA’s Science Activation Program, see NASA Earth Science and Education Update: Introducing the Science Activation Program, The Earth Observer, 35:6, 6–12.)

The Great Lakes Science Center and its two partners – NASA’s Glenn Research Center (GRC) and the Cleveland Orchestra – presented “Total Eclipse Fest 2024,” a three-day celestial celebration at North Coast Harbor in downtown Cleveland beginning April 6 and culminating on the day of the eclipse. The event included free concerts, performances, speakers, and hands-on science activities.
At the heart of the festival was the “NASA Village,” an immersive experience featuring the agency’s major missions and projects aimed at advancing space exploration and revolutionizing air travel. Figure 2 shows the location of each outreach tent in the village, while Figure 3 provides descriptions of each activity. More than 36,000 attendees visited the NASA village over the three-day event.
Exhibits focused on innovations in aeronautics, space, solar, and lunar science, and best practices for ensuring a safe solar eclipse viewing experience. Through virtual and augmented simulations, attendees had the opportunity to take a supersonic flight, walk on Mars, and visit the International Space Station. Attendees of all ages participated in hands-on activities and talked to NASA scientists and engineers about their work and how to join the NASA team. Attendees could also walk through Journey to Tomorrow, a traveling exhibit complete with interactive English and Spanish-language content, and see an Apollo-era Moon rock. Visitors also explored large-scale, inflatable displays of the X-59 plane designed to quiet supersonic air travel, the Space Launch System rocket slated to take the first woman and person of color to the Moon, and a Mars habitat concept. Throughout the NASA Village, attendees could take advantage of several photo opportunities, including iconic NASA cutouts and displays. NASA also hosted astronaut autograph signing sessions, as well as special guest “meet and greets.”

In Cleveland, the eclipse began at 1:59 PM EDT, with totality spanning 3:13–3:17 PM. The eclipse concluded at 4:28 PM. SSO staff supported total eclipse outreach from April 5–9, specifically engaging attendees at the Solar Science tent within the NASA Village and providing information about eclipse safety and heliophysics, and handing out items such as the NASA Science calendar, NASA tote bags, and other outreach materials. SSO also supported a NASA photo booth with eclipse-themed props and took hundreds of souvenir photos for visitors to remember their time at the festival – see Photos 5–9.

In addition to the Cleveland eclipse festival, SSO staff members supported total eclipse engagement in Kerrville, TX, from April 5–9, including several small events at Cailloux Theatre, Doyle Community Center, Trailhead Garden, and Kerrville-Schreiner Park leading up to the eclipse. (While a bit more remote than Cleveland, Kerville was chosen as a SunSpot location during the total eclipse because it was also in the path of the October 2023 annular eclipse, NASA had outreach activities in Kerville for that eclipse as well). The events culminated on April 8 at Louise Hays Park. NASA’s impact on the community was wide-reaching, engaging approximately 4000 individual interactions with community members and visitors. The feedback was overwhelmingly positive and appreciative. On April 8, SSO provided astronaut handler support for NASA Astronaut Reid Wiseman – who will command the Artemis II Moon mission – during a “photos with an astronaut” session. SSO staff also escorted Wiseman to and from a main stage speaking engagement and the NASA broadcast engagement – see Photos 10–13.

As millions gazed at totality from the ground, NASA was conducting science from the skies. Atmospheric Perturbations around the Eclipse Path (APEP), a NASA sounding rocket mission, launched three rockets from NASA’s Wallops Flight Facility in Virginia to study how the sudden dip in sunlight that occurs during an eclipse affects the upper atmosphere. Each rocket deployed four scientific instruments that measured changes in electric and magnetic fields, density, and temperature – see Photo 14.

This photo shows the third APEP sounding rocket – launched during the October 2023 annular eclipse – leaving the launchpad. Photo credit: WSMR Army Photo As part of the Nationwide Eclipse Ballooning Project, student teams constructed hundreds of balloons and launched them during the eclipse, encouraging students to consider careers in the STEM workforce.
Also, two WB-57 aircraft carried instruments to further extend scientific observations made during the eclipse. By taking images above Earth’s atmosphere, scientists were able to see new details of structures in the middle and lower corona. The observations – taken with a camera that images in infrared and visible light at high resolution and high speed – could improve our understanding of the dust ring around the Sun and help search for asteroids that may orbit near the Sun. The WB-57 flights also carried instruments to learn more about the temperature and chemical composition of the corona and coronal mass ejections – or large bursts of solar material. By flying these instruments on a WB-57, the scientists extended their time in the Moon’s shadow by over two minutes from what could be achieved using ground-based observations. A third experiment used an ionosonde to study the ionosphere – the charged layer of Earth’s upper atmosphere. The device functions like a simple radar, sending out high frequency radio signals and listening for their echo rebounding off the ionosphere. The echoes allow researchers to measure how the ionosphere’s charge changed during the eclipse – see Photo 15.

Photo credit: NASA/James Blair The eclipse also provided an opportunity for the public to contribute to the NASA Citizen Science program – a project called Eclipse Soundscapes reached over 900 people during their training programs to prepare for the eclipse. Over 36,000 individual citizen scientists contributed more than 60,000 data submissions across the eclipse path, recording the reactions of wildlife before, during, and after this celestial event.
As part of NASA’s Heliophysics Big Year to celebrate the Sun, NASA played a key role in enabling safe participation as well as working with new-to-NASA audiences. NASA’s Science Mission Directorate ordered and distributed 2.05 million eclipse glasses across the country, with distribution locations including K–12 schools, libraries, minority-serving institutions, community events, museums, partner organizations, underserved communities, science centers, and NASA personnel.
As of April 8, Science Activation reached over 2000 educators across the country through programming designed to prepare educators for the eclipse and provide them with educational resources to train students in STEM. NASA broadcasted a livestream of engagement events on NASA+, the NASA App, NASA.gov, and NASA social media channels. By 4:30 PM EDT, NASA’s websites spiked (e.g., nasa.gov, science.nasa.gov, plus.nasa.gov, and ciencia.nasa.gov) with nearly 28.9 million views and 15.6 million unique visitors. At its peak, 1,458,212 people watched the eclipse broadcast live, experiencing the eclipse together through the eyes of NASA. Total viewership as of 4:30 PM EDT was 13,511,924.
NASA’s Office of Communications Engagement Division organized at least 17 in-person and digital partner interactions, including several Major League Baseball games, Google eclipse safety Doodle and search effect, coverage of NASA on NASDAQ’s screen in Times Square, a solar songs request weekend on Third Rock Radio, and a Snoopy visit to the Cleveland sunspot. Several partners also interacted on social media, including Barbie, Cookie Monster, Elmo, Snoopy, LEGO, and other partner accounts.
Conclusion
The 2024 total eclipse brought joy and awe to millions, inspiring so many to look up, be curious about the natural world around them, and explore the sky. The next total solar eclipse will occur in 2026 and will be visible in Spain, a small area of Portugal, as well as Iceland, Greenland, and Russia. We won’t see another total eclipse in the U.S. until 2044.

Interview with NESC Director, Tim Wilson
NESC Director, Tim Wilson Upon reaching its 20th year of operations at NASA in 2023, the NESC is busier than it has ever been. With a portfolio of more than 160 in-progress requests from Agency programs, NESC Director Tim Wilson spends much of his day prioritizing, allocating funds from the organization’s fixed budget to NASA’s most pressing issues. Of late, the NESC has focused on priority-one requests—projects in the flight phase—such as the Artemis missions and those of NASA’s commercial partners, while lower priority requests like discipline-advancing activities have been placed on hold until the next fiscal year. For Mr. Wilson, each day is a new shuffle of requests, funding, and resources.
When he joined the newly formed NESC in 2003, Mr. Wilson could not have predicted the impact the organization would have on Agency operations. “To be honest, I didn’t really think we’d still be here,” he said. “The NESC was an experiment.” Initiated by the results of the Columbia accident investigation, the idea behind it was that NASA programs would benefit from expert, unbiased perspectives on its tough engineering problems. The vision for the organization was straightforward, but the execution was far more challenging than Mr. Wilson expected.
“When we started those first assessments with the CALIPSO satellite and Shuttle, we had to elbow our way to the table to be accepted. We were new, and no one knew who we were or what we were doing. Back then, programs were worried that we might slow them down or cause problems.” Though Agency leadership had given them the green light, it was up to Mr. Wilson and the NESC’s early members to prove they deserved a seat at those tables. “You have to produce some results before folks respect you,” he said. It was hard won, but with each assessment, the NESC gained that respect by bringing ideas and solutions programs could use.
Two decades in, Mr. Wilson is happy to say the NESC is now invited to the table. “That’s part of why demand has grown as much as it has. Our team is respected, and we’re asked to participate. We’ve gone from being an unknown to an organization they reach out to as a trusted partner: someone who can help them be successful, bring expertise or resources they don’t have, or sometimes just bring another perspective to break a logjam and help them get things done. That’s the shift I have seen over the years. It’s been really encouraging to see it.”
The NESC portfolio of work also has shifted from the early, hectic pace of Shuttle assessments where quick, real-time solutions were needed. In the years following the Shuttle’s retirement, the NESC had the luxury of time to invest in longer-term projects like the design and construction of a composite crew module that would be leveraged in the development of Orion and commercial spacecraft. Today, the pace has ramped up again as Artemis, Dragon, and Starliner head to the Moon and ISS.
“These are real-time activities where you have to engage immediately and be able to add value out of the chute. You don’t have time to come up to speed on the system,” Mr. Wilson said. “We learned with Shuttle that it was important to move quickly and be pre-positioned to help.” Over the years the NESC has cultivated good relationships with programs—keeping people plugged in to their day-to-day activities so that when problems arose, they could engage right away.
“The lesson we learned is you need people doing routine work for those programs all along so that they understand the subsystems and hardware and they’re ready to engage when there’s a real-time problem.” It’s been a balancing act to keep close ties yet remain independent, but Mr. Wilson said the NESC has found an equilibrium. Independent yet parallel modeling and simulation (M&S) is a good example of finding that balance, he said. “We build our own M&S tools in parallel with the programs’ tools to give them a second set of eyes to a problem.” Since 2012, for example, NESC-built M&S trajectory tools have help mitigate risks for Artemis missions’ ascent to orbit, and entry, descent, and landing simulations for CCP provider vehicles.
With capped budgets, the NESC must adjust its scope continually to keep up with the increasing tempo of space exploration. For now, that means focusing on what is most critical and has the highest payback. “We’ll continue to focus on the heavy hitters, the programs that are flying and have a critical immediate need. There are a lot of those, and the pace is ramping up.”
As for the future, Mr. Wilson said, “I have not seen very many Agency initiatives persist the way the NESC has, so I’m thrilled that we have met the needs that we were placed here to meet and that we continue to deliver value, because I think that’s what has kept us rolling and growing over all of this time.”

One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga, spewing volcanic material up to 58 km into the atmosphere. It brought a nearly 15 m tsunami that crashed ashore, destroying villages, and creating a sonic boom that rippled around the world – twice.
Satellites orbiting Earth scrambled to capture images and data of the aftermath of the disaster. Almost a year later, you can now listen to a sonification of the largest eruption of the 21st Century, created using wind data from ESA’s Aeolus mission.
