Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s coverage of the April 8, 2024, total solar eclipse has earned two nominations for the 46th Annual News & Documentary Emmy Awards.
The Academy of Television Arts & Sciences announced the nominations on May 1, recognizing NASA’s outstanding work in sharing this rare celestial event with audiences around the world. The winners are set to be unveiled at a ceremony in late June.
“Total solar eclipses demonstrate the special connection between our Earth, Moon, and Sun by impacting our senses during the breathtaking moments of total alignment that only occur at this time on Earth,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “NASA’s Eclipse coverage team perfectly encapsulated the awe-inspiring experience from start to finish for viewers around the world in this once-in-a-lifetime moment in American history. Congratulations to the entire NASA Eclipse coverage team for their two much-deserved Emmy award nominations!”
The two nominations include:
Outstanding Live News Special for the agency’s live broadcast coverage of the 2024 total solar eclipse. NASA’s live broadcast coverage of the 2024 total solar eclipse was the most ambitious live project ever attempted by the agency. The broadcast spanned three hours as the eclipse traveled 3,000 miles across seven states and two countries. From cities, parks, and stadiums, 11 hosts and correspondents provided on air commentary, interviews, and live coverage. Viewers tuned in from all over the world, including at watch parties in 9 locations, from the Austin Public Library to New York’s Times Square. An interactive “Eclipse Board” provided real time data analysis as the Moon’s shadow crossed North America. Live feeds from astronauts aboard the International Space Station and NASA’s WB-57 high-altitude research aircraft were brought in to provide rare and unique perspectives of the solar event.
In total, NASA received almost 40 million views across its own distribution. Externally, the main broadcast was picked up in 2,208 hits on 568 channels in 25 countries.
Outstanding Show Open or Title Sequence – News for the agency’s show open for the 2024 total solar eclipse. NASA’s show open for the 2024 total solar eclipse live broadcast explores the powerful connections between the Sun, humanity, and the rare moment when day turns to night. From witnessing the Sun’s atmosphere to feeling the dramatic drop in temperature, the video captures the psychological, emotional, and cultural impact of this celestial phenomenon.

Amateur Radio Scientists Shine at the 2025 HamSCI Workshop
A collage of Posters from HamSCI’s March workshop. You can read them all online! Love Ham Radio? The HamSCI project fosters collaboration between amateur radio operators and professional researchers. Its goals are to advance scientific research and understanding through amateur radio activities, encourage the development of modern technologies to support this research, and provide educational opportunities for the amateur community and the public.
HamSCI held its annual Workshop, ‘HamSCI’s Big Year’, at the New Jersey Institute of Technology in late March. Over 100 members of the HamSCI community attended: researchers, students (secondary through graduate level), and citizen scientist volunteers. Over the two-day event, in-person and virtual participants experienced twenty-five talks on topics ranging from analysis of HamSCI’s 2023/24 Festivals of Eclipse Ionospheric Science events to space weather observations made during the May 10, 2024 geomagnetic superstorm.
The Workshop hosted a variety of Keynote and Invited Tutorial speakers, including distinguished scientists and leaders in the Amateur (ham) Radio community. The Workshop concluded with a poster session, featuring current research, ongoing educational activities, and concepts for future events involving Sun-space-Earth science topics. Posters were submitted from the US, Brazil, Egypt, the United Kingdom, and Turkey.
Explore the workshop presentations and posters. Videos of conference presentations will be available at the HamSCI website in a few months.
HamSCI is supported by NASA, the National Science Foundation, and the Amateur Radio Digital Communications (ARDC) foundation.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
As associate administrator for NASA’s Space Operations Mission Directorate Ken Bowersox puts it, “nothing happens without communications.”
And effective communications require the use of radio waves.
None of NASA’s exciting science and engineering endeavors would be possible without the use of radio waves to send data, communications, and commands between researchers or flight controllers and their flight platforms or instruments.
Reflecting on his time as a pilot, commander, and mission specialist during the Space Shuttle Program, Bowersox says, “If you’re not there physically, you can’t be a part of the team. But if you’re getting the data, whether it’s video, telemetry data with states of switches, or individual parameters on temperatures or pressures, then you can act on it and provide information to the spacecraft team so they can do the right thing in their operation.”
These vital data and communications functions, as well as the gathering of valuable scientific data through remote sensing applications, all use radio frequencies (RF) within the electromagnetic spectrum. NASA centers and facilities also use the RF spectrum to support their everyday operations, including the walkie-talkies used by security guards, air traffic control systems around airfields, and even office Wi-Fi routers and wireless keyboards.
Nothing happens without communications.
Ken Bowersox
NASA Astronaut & Associate Administrator for NASA's Space Operations Mission Directorate
All of NASA’s uses of the RF spectrum are shared, with different radio services supporting other kinds of uses. Service allocation is a fundamental concept in spectrum regulation and defines how the spectrum is shared between different types of applications. A service allocation defines ranges, or bands, of radio frequencies that can be used by a particular type of radio service. For example, a television broadcasting satellite operates in frequency bands allocated to the broadcasting satellite service, terrestrial cellular services operate in bands allocated for the mobile service, and the communications antennas on the International Space Station (ISS) operate in bands allocated to space operations service.
However, an allocation is not a license to operate — it does not authorize a specific system or operator to use particular frequencies. Such authority is granted through domestic and international regulatory processes.
Most frequency bands of the RF spectrum are shared, and each frequency band typically has two or more radio services allocated to it. Careful spectrum regulation, planning, and management aim to identify mutually compatible services to share frequency bands while limiting its negative impacts.
NASA’s Most Notable Spectrum Uses
Many of NASA’s most notable uses of spectrum rely on the following service allocations:
Earth exploration-satellite service Space research service Space operations service Inter-satellite service Note that allocations in the Earth exploration-satellite service and the space research service are designated either for communications links in the Earth-to-space, space-to-Earth, or space-to-space directions or designated for active or passive sensing of Earth or celestial objects (respectively) to differentiate the types of uses within the service and afford the requisite protections.

First Results from the Eclipse Soundscapes Project: Webinar on May 7
How do the sudden darkness and temperature changes of a solar eclipse impact life on Earth? The Eclipse Soundscapes project invited you to document changes in the environment during the week of the April 8, 2024 total solar eclipse, using your own senses or an audiomoth sound recorder.
Thanks to your participation, the Eclipse Soundscapes team collected 25 terabytes of audio data during the 2023 and 2024 solar eclipses. “It was really empowering for me to participate in a scientific research study with my son beside me so he could see how scientific data can be (collected),” said one Eclipse Soundscapes volunteer.
More than 500 volunteers collected data using AudioMoth recorders during the April 8, 2024 eclipse for the Eclipse Soundscapes project. Credit: Eclipse Soundscapes Since the eclipse, the Eclipse Soundscapes team has been turning the submitted data into a new, carefully validated data set. They have been assessing recording quality, verifying timestamps, and logging other kinds of information that support the submitted data. With the newly validated data, they are now using machine learning to study wildlife behavior and compare regional differences. They do some of this work using spectrographic analysis—spreading out the sound into different frequency ranges like a prism spreads light into a rainbow. The team is also working to make the validated data freely available to the public on the Zenodo website—a free, open-source research data repository developed by CERN (the European Organization for Nuclear Research) that allows researchers to share and preserve their work, regardless of discipline or format.
The team’s first inspection of the data suggests that some species may mimic dusk-like behavior during totality. Want to hear more early results? You can join the team’s live webinar on May 7, 2025, at 2:00 p.m. EST with Dr. Brent Pease. Register now at EclipseSoundscapes.org. You can also explore this interactive map of data analysis sites, with details about each site, including partner organizations.
