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.

5 Min Read NASA 3D Wind Measuring Laser Aims to Improve Forecasts from Air, Space
3D wind measurements from NASA's Aerosol Wind Profiler instrument flying on board a specially mounted aircraft along the East Coast of the U.S. and across the Great Lakes region on Oct. 15, 2024. Credits: NASA/Scientific Visualization Studio Since last fall, NASA scientists have flown an advanced 3D Doppler wind lidar instrument across the United States to collect nearly 100 hours of data — including a flight through a hurricane. The goal? To demonstrate the unique capability of the Aerosol Wind Profiler (AWP) instrument to gather extremely precise measurements of wind direction, wind speed, and aerosol concentration – all crucial elements for accurate weather forecasting.
Weather phenomena like severe thunderstorms and hurricanes develop rapidly, so improving predictions requires more accurate wind observations.
“There is a lack of global wind measurements above Earth’s surface,” explained Kris Bedka, the AWP principal investigator at NASA’s Langley Research Center in Hampton, Virginia. “Winds are measured by commercial aircraft as they fly to their destinations and by weather balloons launched up to twice per day from just 1,300 sites across the globe. From space, winds are estimated by tracking cloud and water vapor movement from satellite images.”
However, in areas without clouds or where water vapor patterns cannot be easily tracked, there are typically no reliable wind measurements. The AWP instrument seeks to fill these gaps with detailed 3D wind profiles.
The AWP instrument (foreground) and HALO instrument (background) was integrated onto the floorboard of NASA’s G-III aircraft. Kris Bedka, project principal investigator, sitting in the rear of the plane, monitored the data during a flight on Sept. 26, 2024. NASA/Maurice Cross Mounted to an aircraft with viewing ports underneath it, AWP emits 200 laser energy pulses per second that scatter and reflect off aerosol particles — such as pollution, dust, smoke, sea salt, and clouds — in the air. Aerosol and cloud particle movement causes the laser pulse wavelength to change, a concept known as the Doppler effect.
The AWP instrument sends these pulses in two directions, oriented 90 degrees apart from each other. Combined, they create a 3D profile of wind vectors, representing both wind speed and direction.
We are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.

“The Aerosol Wind Profiler is able to measure wind speed and direction, but not just at one given point,” Bedka said. “Instead, we are measuring winds at different altitudes in the atmosphere simultaneously with extremely high detail and accuracy.”
Vectors help researchers and meteorologists understand the weather, so AWP’s measurements could significantly advance weather modeling and forecasting. For this reason, the instrument was chosen to be part of the National Oceanic and Atmospheric Administration’s (NOAA) Joint Venture Program, which seeks data from new technologies that can fill gaps in current weather forecasting systems. NASA’s Weather Program also saw mutual benefit in NOAA’s investments and provided additional support to increase the return on investment for both agencies.
On board NASA’s Gulfstream III (G-III) aircraft, AWP was paired with the agency’s High-Altitude Lidar Observatory (HALO) that measures water vapor, aerosols, and cloud properties through a combined differential absorption and high spectral resolution lidar.
Working together for the first time, AWP measured winds, HALO collected water vapor and aerosol data, and NOAA dropsondes (small instruments dropped from a tube in the bottom of the aircraft) gathered temperature, water vapor, and wind data.

NASA/Maurice Cross “With our instrument package on board small, affordable-to-operate aircraft, we have a very powerful capability,” said Bedka. “The combination of AWP and HALO is NASA’s next-generation airborne weather remote sensing package, which we hope to also fly aboard satellites to benefit everyone across the globe.”

This visualization shows AWP 3D measurements gathered on Oct. 15, 2024, as NASA’s G-III aircraft flew along the East Coast of the U.S. and across the Great Lakes region. Laser light that returns to AWP as backscatter from aerosol particles and clouds allows for measurement of wind direction, speed, and aerosol concentration as seen in the separation of data layers. NASA/Scientific Visualization Studio “When we took off on this particular day, I thought that we would be finding a clear atmosphere with little to no aerosol return because we were flying into what was the first real blast of cool Canadian air of the fall,” described Bedka. “What we found was quite the opposite: an aerosol-rich environment which provided excellent signal to accurately measure winds.”
During the Joint Venture flights, Hurricane Helene was making landfall in Florida. The AWP crew of two pilots and five science team members quickly created a flight plan to gather wind measurements along the outer bands of the severe storm.

NASA/Kris Bedka “A 3D wind profile can significantly improve weather forecasts, particularly for storms and hurricanes,” said Harshesh Patel, NOAA’s acting Joint Venture Program manager. “NASA Langley specializes in the development of coherent Doppler wind lidar technology and this AWP concept has potential to provide better performance for NOAA’s needs.”

“The need to improve global 3D wind models requires a space-based platform,” added Patel. “Instruments like AWP have specific space-based applications that potentially align with NOAA’s mission to provide critical data for improving weather forecasting.”

These missions studied atmospheric processes within the planetary boundary layer, the lowest part of the atmosphere, that drives the weather conditions we experience on the ground.

Image: The Atomic Clock Ensemble in Space (ACES), ESA’s state-of-the-art timekeeping facility, is now installed on the Columbus laboratory of the International Space Station. This still image, captured by external cameras on the Station, shows ACES after installation. For 25 years, cameras on the Station have documented activities in orbit, providing real-time views of operations like this one – a rare and remarkable perspective from space.
On 25 April, the Canadian Space Agency’s robotic arm carefully extracted ACES from the SpaceX Dragon trunk and secured it onto the Columbus External Payload Facility, next to ESA’s space storm hunter ASIM (Atmospheric-Space Interactions Monitor). Mounted on the Earth-facing side, ACES will connect with ground clocks worldwide as the Station orbits Earth sixteen times a day.
Developed by ESA with European industry led by Airbus, ACES carries the most precise clocks ever sent to space: PHARAO, developed by the French space agency CNES, and the Space Hydrogen Maser from Safran Timing Technologies in Switzerland. Together with a sophisticated microwave and laser link, they will compare time between space and Earth with unprecedented accuracy, testing fundamental physics and advancing future time standards.
In March 2025, ACES arrived at NASA’s Kennedy Space Center, where ESA, Airbus and NASA teams prepared the payload for flight. ACES launched on 21 April aboard a SpaceX Falcon 9 as part of the 32nd commercial resupply services mission to the International Space Station. Today, ACES was successfully switched on for the first time, establishing communications with ground control and stabilising its thermal systems in preparation for clock operations.
A six-month commissioning phase now begins, after which ACES will embark on its two-year science mission, opening new frontiers in fundamental physics and timekeeping.

NASA’s James Webb Space Telescope has taken the most detailed image of planetary nebula NGC 1514 to date thanks to its unique mid-infrared observations. Webb shows its rings as intricate clumps of dust. It’s also easier to see holes punched through the bright pink central region. Credits:
NASA, ESA, CSA, STScI, Michael Ressler (NASA-JPL), Dave Jones (IAC) Gas and dust ejected by a dying star at the heart of NGC 1514 came into complete focus thanks to mid-infrared data from NASA’s James Webb Space Telescope. Its rings, which are only detected in infrared light, now look like “fuzzy” clumps arranged in tangled patterns, and a network of clearer holes close to the central stars shows where faster material punched through.
“Before Webb, we weren’t able to detect most of this material, let alone observe it so clearly,” said Mike Ressler, a researcher and project scientist for Webb’s MIRI (Mid-Infrared Instrument) at NASA’s Jet Propulsion Laboratory in southern California. He discovered the rings around NGC 1514 in 2010 when he examined the image from NASA’s Wide-field Infrared Survey Explorer (WISE). “With MIRI’s data, we can now comprehensively examine the turbulent nature of this nebula,” he said.
This scene has been forming for at least 4,000 years — and will continue to change over many more millennia. At the center are two stars that appear as one in Webb’s observation, and are set off with brilliant diffraction spikes. The stars follow a tight, elongated nine-year orbit and are draped in an arc of dust represented in orange.
One of these stars, which used to be several times more massive than our Sun, took the lead role in producing this scene. “As it evolved, it puffed up, throwing off layers of gas and dust in in a very slow, dense stellar wind,” said David Jones, a senior scientist at the Institute of Astrophysics on the Canary Islands, who proved there is a binary star system at the center in 2017.
Once the star’s outer layers were expelled, only its hot, compact core remained. As a white dwarf star, its winds both sped up and weakened, which might have swept up material into thin shells.

Webb’s observations show the nebula is tilted at a 60-degree angle, which makes it look like a can is being poured, but it’s far more likely that NGC 1514 takes the shape of an hourglass with the ends lopped off. Look for hints of its pinched waist near top left and bottom right, where the dust is orange and drifts into shallow V-shapes.
What might explain these contours? “When this star was at its peak of losing material, the companion could have gotten very, very close,” Jones said. “That interaction can lead to shapes that you wouldn’t expect. Instead of producing a sphere, this interaction might have formed these rings.”
Though the outline of NGC 1514 is clearest, the hourglass also has “sides” that are part of its three-dimensional shape. Look for the dim, semi-transparent orange clouds between its rings that give the nebula body.
A Network of Dappled Structures
The nebula’s two rings are unevenly illuminated in Webb’s observations, appearing more diffuse at bottom left and top right. They also look fuzzy, or textured. “We think the rings are primarily made up of very small dust grains,” Ressler said. “When those grains are hit by ultraviolet light from the white dwarf star, they heat up ever so slightly, which we think makes them just warm enough to be detected by Webb in mid-infrared light.”
In addition to dust, the telescope also revealed oxygen in its clumpy pink center, particularly at the edges of the bubbles or holes.
NGC 1514 is also notable for what is absent. Carbon and more complex versions of it, smoke-like material known as polycyclic aromatic hydrocarbons, are common in planetary nebulae (expanding shells of glowing gas expelled by stars late in their lives). Neither were detected in NGC 1514. More complex molecules might not have had time to form due to the orbit of the two central stars, which mixed up the ejected material. A simpler composition also means that the light from both stars reaches much farther, which is why we see the faint, cloud-like rings.
What about the bright blue star to the lower left with slightly smaller diffraction spikes than the central stars? It’s not part of this nebula. In fact, this star lies closer to us.
This planetary nebula has been studied by astronomers since the late 1700s. Astronomer William Herschel noted in 1790 that NGC 1514 was the first deep sky object to appear genuinely cloudy — he could not resolve what he saw into individual stars within a cluster, like other objects he cataloged. With Webb, our view is considerably clearer.
NGC 1514 lies in the Taurus constellation approximately 1,500 light-years from Earth.
The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
