Inside a laboratory in the Space Systems Processing Facility at NASA’s Kennedy Space Center in Florida, a payload implementation team member harvests ‘Outredgeous’ romaine lettuce growing in the Advanced Plant Habitat ground unit on Thursday, April 24, 2025. The harvest is part of the ground control work supporting Plant Habitat-07, which launched to the International Space Station aboard NASA’s SpaceX 31st commercial resupply services mission.
The experiment focuses on studying how optimal and suboptimal moisture conditions affect plant growth, nutrient content, and the plant microbiome in microgravity. Research like this continues NASA’s efforts to grow food that is not only safe but also nutritious for astronauts living and working in the harsh environment of space.
The ‘Outredgeous’ romaine lettuce variety was first grown aboard the space station in 2014, and Plant Habitat-07 builds on that legacy, using the station’s Advanced Plant Habitat to expand understanding of how plants adapt to spaceflight conditions. Findings from this work will support future long-duration missions to the Moon, Mars, and beyond, and could also lead to agricultural advances here on Earth.

Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms.
Microalgae in microgravity
Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein yield. Microalgae are nutrient dense and produce proteins with essential amino acids, beneficial fatty acids, B vitamins, iron, and fiber. These organisms also can be used to make fuel, cooking oil, medications, and materials. Learning more about microalgae growth and protein production in space could support development of sustainable alternatives to meat and dairy. Such alternatives could provide a food source on future space voyages and for people on Earth and be used to make biofuels and bioactive compounds in medicines.
Microscopic motion
Portland State University These swimming microalgae are visible thanks to the Extant Life Volumetric Imaging System or ELVIS, a fluorescent 3D imaging microscope that researchers are testing aboard the International Space Station. The investigation studies both active behaviors and genetic changes of microscopic algae and marine bacteria in response to spaceflight. ELVIS is designed to autonomously capture microscopic motion in 3D, a capability not currently available on the station. The technology could be useful for a variety of research in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms.
Genetics of biofilms
BioServe This preflight image shows sample chambers for the Genetic Exchange in Microgravity for Biofilm Bioremediation (GEM-B2) investigation, which examines the mechanisms of gene transfer within biofilms under microgravity conditions. Biofilms are communities of microorganisms that collect and bind to a surface. They can clog and foul water systems, often leave a residue that can cause infections, and may become resistant to antibiotics. Researchers could use results from this work to develop genetic manipulations that inhibit biofilm formation, helping to maintain crew health and safety aboard the International Space Station and on future missions.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Nemanja Jovanovic, lead instrument scientist at Caltech, presents at the Emerging Technologies for Astrophysics workshop, held at NASA’s Ames Research Center in California’s Silicon Valley. The workshop brought together experts in astrophysics to discuss how advanced technologies could impact future mission planning.NASA/Donald Richey The future of astrophysics research could unlock the secrets of the universe, and emerging technologies like artificial intelligence, quantum sensing, and advanced materials may hold the key to faster, more efficient discovery. Advancements and implementations of new technologies are imperative for observational astrophysics to achieve the next level of detection.
NASA’s Emerging Technologies for Astrophysics workshop brought together subject matter experts from industry, government, and academia to explore the state of new and disruptive technologies. The meeting was an effort to identify specific applications for astrophysics missions and better understand how their infusion into future NASA space telescopes could be accelerated.
The workshop took place at NASA’s Ames Research Center in California’s Silicon Valley,. supporting the agency’s efforts to make partnership with public and private industry and collaborative mission planning possible.
“The profound questions about the nature of our universe that astrophysics at NASA answers require giant leaps in technology,” explained Mario Perez, chief technologist for the Astrophysics Division at NASA Headquarters in Washington. “Spotting potential in early-stage tech by encouraging discussions between imaginative researchers helps expand the scope of science and lessen the time required to achieve the next generation of astrophysics missions.”
Emerging technologies like artificial intelligence can support the design and optimization of future missions, and participants focused efforts on combining technologies to push research further. “Cross-pollination” of advanced materials like composites with advanced manufacturing, metamaterials, and photonic chips could support advancement in imaging missions beyond existing mechanical stability needs.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) has dubbed 2025 the “International Year of Quantum Science and Technology” in recognition of a century of quantum mechanics. Workshop participants discussed how quantum sensing could enable more precise measurements, achieve “super resolution” by filling in missing details in lower resolution images, and provide greater capabilities in forthcoming space telescopes.
“This gathering of experts was an opportunity to find ways where we can increase the capabilities of future space instrumentation and accelerate technology development for infusion into NASA astrophysics missions,” said Naseem Rangwala, astrophysics branch chief at NASA Ames. “We can speed up the process of how we develop these future projects by using the emerging technologies that are incubated right here in Silicon Valley.”
The findings from this workshop and ongoing discussions will support efforts to study and invest in technologies to advance astrophysics missions with greater speed and efficiency.

Help Classify Galaxies Seen by NASA’s James Webb Space Telescope!
The Galaxy Zoo classification interface shows you an image from NASA’s Webb telescope and asks you questions about it. Image credit: Galaxy Zoo, Zooniverse. Inset galaxy: NASA/STScI/CEERS/TACC/S. Finkelstein/M. Bagley/Z. Levay/A. Pagan NASA needs your help identifying the shapes of thousands of galaxies in images taken by our James Webb Space Telescope with the Galaxy Zoo project. These classifications will help scientists answer questions about how the shapes of galaxies have changed over time, what caused these changes, and why. Thanks to the light collecting power of Webb, there are now over 500,000 images of galaxies on website of the Galaxy Zoo citizen science project—more images than scientists can classify by themselves.
“This is a great opportunity to see images from the newest space telescope,” said volunteer Christine Macmillan from Aberdeen, Scotland. “Galaxies at the edge of our universe are being seen for the first time, just as they are starting to form. Just sign up and answer simple questions about the shape of the galaxy that you are seeing. Anyone can do it, ages 10 and up!”
As we look at more distant objects in the universe, we see them as they were billions of years ago because light takes time to travel to us. With Webb, we can spot galaxies at greater distances than ever before. We’re seeing what some of the earliest galaxies ever detected look like, for the first time. The shapes of these galaxies tell us about how they were born, how and when they formed stars, and how they interacted with their neighbors. By looking at how more distant galaxies have different shapes than close galaxies, we can work out which processes were more common at different times in the universe’s history.
At Galaxy Zoo, you’ll first examine an image from the Webb telescope. Then you will be asked several questions, such as ‘Is the galaxy round?’, or ‘Are there signs of spiral arms?’. If you’re quick, you may even be the first person to see the galaxies you’re asked to classify.
“I’m amazed and honored to be one of the first people to actually see these images! What a privilege!” said volunteer Elisabeth Baeten from Leuven, Belgium.
Galaxy Zoo is a citizen science project with a long history of scientific impact. Galaxy Zoo volunteers have been exploring deep space since July 2007, starting with a million galaxies from a telescope in New Mexico called the Sloan Digital Sky Survey and then, moving on to images from space telescopes like NASA’s Hubble Space Telescope and ESA (European Space Agency)’s Euclid telescope. The project has revealed spectacular mergers, taught us about how the black holes at the center of galaxies affect their hosts, and provided insight into how features like spiral arms form and grow.
Now, in addition to adding new data from Webb, the science team has incorporated an AI algorithm called ZooBot, which will sift through the images first and label the ‘easier ones’ where there are many examples that already exist in previous images from the Hubble Space Telescope. When ZooBot is not confident on the classification of a galaxy, perhaps due to complex or faint structures, it will show it to users on Galaxy Zoo to get their human classifications, which will then help ZooBot learn more. Working together, humans and AI can accurately classify limitless numbers of galaxies. The Galaxy Zoo science team acknowledges support from the International Space Sciences Institute (ISSI), who provided funding for the team to get together and work on Galaxy Zoo. Join the project now.
