Preparations for Next Moonwalk Simulations Underway (and Underwater)
On April 16, 2025, the Earth Science Division at NASA’s Ames Research Center in Silicon Valley held an Earth Science Showcase to share its work with the center and their families. As part of this event, kids were invited to share something they like about the Earth. These are their masterpieces.

Video: 00:02:22 ESA’s state-of-the-art Biomass mission has been designed to shed new light on the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the forest canopy and whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.

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.

NASA The Sun’s glint beams off a partly cloudy Atlantic Ocean just after sunrise as the International Space Station orbited 263 miles above on March 5, 2025. The space station serves as a unique platform for observing Earth with both hands-on and automated equipment. Station crew members have produced hundreds of thousands of images, recording phenomena such as storms in real time, observing natural events such as volcanic eruptions as they happen, and providing input to ground personnel for programming automated Earth-sensing systems.
NASA has been observing Earth from space for more than 60 years, with cutting-edge scientific technology that can revolutionize our understanding of our home planet and provide benefits to all humanity.
