Astronauts aboard the International Space Station conducted hundreds of science experiments and technology demonstrations during 2024. Crew members participated in research across a variety of scientific disciplines and accomplished milestones demonstrating benefits for future missions and humanity back on Earth. Their work included snapping thousands of images of Earth to understand our planet’s changing landscape, bioprinting cardiac tissues to validate technology for organ manufacturing in space, and studying physical phenomena that could improve drug delivery systems and technology for plant growth in reduced gravity.
This new image gallery showcases dozens of awe-inspiring photos and includes details about the research benefits of the state-of-the-art science happening aboard space station.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and ‘weighed’ a galaxy, in the early Universe, that has a mass that is similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Found at around 600 million years after the Big Bang, this lightweight galaxy, nicknamed the Firefly Sparkle, is gleaming with star clusters – 10 in total – that researchers examined in great detail. Other galaxies Webb has detected at this period in the history of the Universe are significantly more massive.

At Goddard Space Flight Center, the GSFC Data Science Group has completed the testing for their SatVision Top-of-Atmosphere (TOA) Foundation Model, a geospatial foundation model for coarse-resolution all-sky remote sensing imagery. The team, comprised of Mark Carroll, Caleb Spradlin, Jordan Caraballo-Vega, Jian Li, Jie Gong, and Paul Montesano, has now released their model for wide application in science investigations.
Foundation models can transform the landscape of remote sensing (RS) data analysis by enabling the pre-training of large computer-vision models on vast amounts of remote sensing data. These models can be fine-tuned with small amounts of labeled training and applied to various mapping and monitoring applications. Because most existing foundation models are trained solely on cloud-free satellite imagery, they are limited to applications of land surface or require atmospheric corrections. SatVision-TOA is trained on all-sky conditions which enables applications involving atmospheric variables (e.g., cloud or aerosol).
SatVision TOA is a 3 billion parameter model trained on 100 million images from Moderate Resolution Imaging Spectroradiometer (MODIS). This is, to our knowledge, the largest foundation model trained solely on satellite remote sensing imagery. By including “all-sky” conditions during pre-training, the team incorporated a range of cloud conditions often excluded in traditional modeling. This enables 3D cloud reconstruction and cloud modeling in support of Earth and climate science, offering significant enhancement for large-scale earth observation workflows.
With an adaptable and scalable model design, SatVision-TOA can unify diverse Earth observation datasets and reduce dependency on task-specific models. SatVision-TOA leverages one of the largest public datasets to capture global contexts and robust features. The model could have broad applications for investigating spectrometer data, including MODIS, VIIRS, and GOES-ABI. The team believes this will enable transformative advancements in atmospheric science, cloud structure analysis, and Earth system modeling.
The model architecture and model weights are available on GitHub and Hugging Face, respectively. For more information, including a detailed user guide, see the associated white paper: SatVision-TOA: A Geospatial Foundation Model for Coarse-Resolution All-Sky Remote Sensing Imagery.

Right: The reconstructed images produced by the model, along with their respective Structural Similarity Index Measure (SSIM) scores. These examples illustrate the model’s ability to preserve structural detail and reconstruct heterogeneous features, such as cloud textures and land-cover transitions, with high fidelity.NASAView the full article

NASA’s podcasts let you experience the thrill of space exploration without ever leaving Earth.Credit: NASA NASA’s audio storytelling reached new frontiers in 2024, with Spotify Wrapped revealing the agency’s podcasts as a favorite among listeners worldwide. In celebration of the milestone, NASA astronaut Nick Hague spoke with Spotify about what space sounded like this year.
“Music is one of those things that connects us to the planet,” said Hague, in the video released on Spotify and NASA social accounts. “Music is a vital part of life up here. The soundtrack up here, it’s just going all the time. Everybody’s got their own flavor of music. Every Friday night the crew gets together, we turn on music and we stream things that we like. Whether they’re into pop or hard rock, it’s an international mix. When I think of space walks, I think of classical music, slow, methodical tunes, because that is the way that we conduct spacewalks. Slowly and methodically. Classical music captures the essence of, just floating in space.”
With listeners in more than 100 countries, NASA podcasts reached new audiences and inspired people around the world on Spotify this year. Other 2024 highlights included:
Ranked as a top choice for thousands of listeners seeking to learn about science and space. Spent a combined 37 weeks in Spotify’s top charts for science podcasts. The top streamed podcast was “NASA’s Curious Universe”, and the top streamed episode was “A Year in Mars Dune Alpha.” “We’re thrilled to have our space-centric content featured in Spotify Wrapped 2024,” said Brittany Brown, director of digital communications, NASA Headquarters in Washington. “Our collaboration with Spotify is a testament to NASA’s commitment to producing innovative and engaging content. We’re excited to see how audiences continue to respond to this unique listening experience only NASA can provide.”
The agency’s podcasts cover a wide range of topics, including in-depth conversations with NASA astronauts, stories that take audiences on a tour of the galaxy, and Spanish-language content.
“Music, just like space, connects us all,” said Katie Konans, audio program lead, eMITS contract with NASA. “Our partnership with Spotify has allowed NASA to share the wonder and excitement of space with music and podcast lovers globally. This year, we’re thrilled to take this connection to new heights by bringing the Spotify Wrapped 2024 conversation beyond planet Earth.”
NASA released its collection of original podcasts on Spotify in 2023, furthering the agency’s mission to engage the Artemis Generation in the science, space exploration, and discovery.
In addition to Spotify, users may find NASA podcasts on Apple Podcasts, Google Podcasts, and Soundcloud.
