A host of scientific investigations await the crew of NASA’s SpaceX Crew-11 mission during their long-duration expedition aboard the International Space Station. NASA astronauts Zena Cardman and Mike Fincke, and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui, are set to study plant cell division and microgravity’s effects on bacteria-killing viruses, as well as perform experiments to produce a higher volume of human stem cells and generate on-demand nutrients.
Here are details on some of the research scheduled during the Crew-11 mission:
Making more stem cells
Cultures of stem cells grown in 2D on Earth, left, and as 3D spheres in simulated microgravity on Earth.BioServe A stem cell investigation called StemCellEx-IP1 evaluates using microgravity to produce large numbers of induced pluripotent stem cells. Made by reprogramming skin or blood cells, these stem cells can transform into any type of cell in the body and are used in regenerative medicine therapies for many diseases. However, producing enough cells on the ground is a challenge.
Researchers plan to use the microgravity environment aboard the space station to demonstrate whether generating 1,000 times more cells is possible and whether these cells are of higher quality and better for clinical use than those made on Earth. If proven, this could significantly improve future patient outcomes.
“This type of stem cell research is a chance to find treatments and maybe even cures for diseases that currently have none,” said Tobias Niederwieser of BioServe Space Technologies, which developed the investigation. “This represents an incredible potential to make life here on Earth better for all of us. We can take skin or blood cells from a patient, convert them into stem cells, and produce custom cell-therapy with little risk for rejection, as they are the person’s own cells.”
Alternative to antibiotics
Genes in Space-12 student investigators Isabella Chuang, left, and Julia Gross, middle, with mentor Kayleigh Ingersoll Omdahl.Genes in Space Genes in Space is a series of competitions in which students in grades 7 through 12 design DNA experiments that are flown to the space station. Genes in Space-12 examines the effects of microgravity on interactions between certain bacteria and bacteriophages, which are viruses that infect and kill bacteria. Bacteriophages already are used to treat bacterial infections on Earth.
“Boeing and miniPCR bio co-founded this competition to bring real-world scientific experiences to the classroom and promote molecular biology investigations on the space station,” said Scott Copeland of Boeing, and co-founder of Genes in Space. “This
investigation could establish a foundation for using these viruses to treat bacterial infections in space, potentially decreasing the dependence on antibiotics.”
“Previous studies indicate that bacteria may display increased growth rates and virulence in space, while the antibiotics used to combat them may be less effective,” said Dr. Ally Huang, staff scientist at miniPCR bio. “Phages produced in space could have profound implications for human health, microbial control, and the sustainability of long-duration remote missions. Phage therapy tools also could revolutionize how we manage bacterial infections and microbial ecosystems on Earth.”
Edible organisms
A purple, pre-incubation BioNutrients-3 bag, left, and a pink bag, right, which has completed incubation, on a purple and pink board used for comparison.NASA Some vitamins and nutrients in foods and supplements lose their potency during prolonged storage, and insufficient intake of even a single nutrient can lead to serious diseases, such as a vitamin C deficiency, causing scurvy. The BioNutrients-3 experiment builds on previous investigations looking at ways to produce on-demand nutrients in space using genetically engineered organisms that remain viable for years. These include yogurt and a yeast-based beverage made from yeast strains previously tested aboard station, as well as a new, engineered co-culture that produces multiple nutrients in one sample bag.
“BioNutrients-3 includes multiple food safety features, including pasteurization to kill microorganisms in the sample and a demonstration of the feasibility of using a sensor called E-Nose that simulates an ultra-sensitive nose to detect pathogens,” said Kevin Sims, project manager at NASA’s Ames Research Center in California’s Silicon Valley.
Another food safety feature is a food-grade pH indicator to track bacterial growth.
“These pH indicators help the crew visualize the progress of the yogurt and kefir samples,” Sims said. “As the organisms grow, they generate lactic acid, which lowers the pH and turns the indicator pink.”
The research also features an investigation of yogurt passage, which seeds new cultures using a bit of yogurt from a finished bag, much like maintaining a sourdough bread starter. This method could sustain a culture over multiple generations, eliminating concerns about yogurt’s shelf life during a mission to the Moon or Mars while reducing launch mass.
Understanding cell division
Cells of green algae dividing.University of Toyama The JAXA Plant Cell Division investigation examines how microgravity affects cell division in green algae and a strain of cultured tobacco cells. Cell division is a fundamental element of plant growth, but few studies have examined it in microgravity.
“The tobacco cells divide frequently, making the process easy to observe,” said Junya Kirima of JAXA. “We are excited to reveal the effects of the space environment on plant cell division and look forward to performing time-lapse live imaging of it aboard the space station.”
Understanding this process could support the development of better methods for growing plants for food in space, including on the Moon and Mars. This investigation also could provide insight to help make plant production systems on Earth more efficient.
For nearly 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and conducting critical research for the benefit of humanity and our home planet. Space station research supports the future of human spaceflight as NASA looks toward deep space missions to the Moon under the Artemis campaign and in preparation for future human missions to Mars, as well as expanding commercial opportunities in low Earth orbit and beyond.

Pictured from left: Roscosmos cosmonaut Oleg Platonov, NASA astronauts Mike Fincke and Zena Cardman, and JAXA (Japan Aerospace Exploration Agency) astronaut Kimiya Yui (Credit: SpaceX). NASA’s SpaceX Crew-11 mission is set to launch a four-person crew to the International Space Station later this summer. Some of the crew have volunteered to participate in a series of experiments to address health challenges astronauts may face on deep space missions during NASA’s Artemis campaign and future human expeditions to Mars.
The research during Crew-11 includes simulated lunar landings, tactics to safeguard vision, and other human physiology studies led by NASA’s Human Research Program.
Select crew members will participate in a series of simulated Moon landings, before, during, and after their flight. Using a handheld controller and multiple screens, the astronauts will fly through simulated scenarios created to resemble the lunar South Pole region that Artemis crews plan to visit. This experiment allows researchers to evaluate how different gravitational forces may disorient astronauts and affect their ability to pilot a spacecraft, like a lunar lander.
“Even though many landing tasks are automated, astronauts must still know how to monitor the controls and know when to take over to ensure a safe landing,” said Scott Wood, a neuroscientist at NASA’s Johnson Space Center in Houston coordinating the scientific investigation. “Our study assesses exactly how changes in gravity affect spatial awareness and piloting skills that are important for navigating these scenarios.”
A ground control group completing the same tasks over a similar timeframe will help scientists better understand gravitational effects on human performance. The experiment’s results could inform the pilot training needed for future Artemis crews.
“Experiencing weightlessness for months and then feeling greater levels of gravity on a planet like Mars, for example, may increase the risk of disorientation,” said Wood. “Our goal is to help astronauts adapt to any gravitational change, whether it’s to the Moon, a new planet, or landing back on Earth.”
Other studies during the mission will explore possible ways to treat or prevent a group of eye and brain changes that can occur during long-duration space travel, called spaceflight associated neuro-ocular syndrome (SANS).
Some researchers suspect the redistribution of bodily fluids in constant weightlessness may increase pressure in the head and contribute to SANS. One study will investigate fluid pressure on the brain while another will examine how the body processes B vitamins and whether supplements can affect how astronauts respond to bodily fluid shifts. Participating crew members will test whether a daily B vitamin supplement can eliminate or ease symptoms of SANS. Specific crew members also will wear thigh cuffs to keep bodily fluids from traveling headward.
Crew members also will complete another set of experiments, called CIPHER (Complement of Integrated Protocols for Human Exploration Research), which measures how multiple systems within the human body change in space. The study includes vision assessments, MRI scans, and other medical exams to provide a complete overview of the whole body’s response to long-duration spaceflight.
Several other studies involving human health and performance are also a part of Crew-11’s science portfolio. Crew members will contribute to a core set of measurements called Spaceflight Standard Measures, which collects physical data and biological samples from astronauts and stores them for other comparative studies. Participants will supply biological samples, such as blood and urine, for a study characterizing how spaceflight alters astronauts’ genetic makeup. In addition, volunteers will test different exercise regimens to help scientists explore what activities remain essential for long-duration journeys.
After landing, participating crew members will complete surveys to track any discomfort, such as scrapes or bruises, acquired from re-entry. The data will help clarify whether mission length increases injury risks and could help NASA design landing systems on future spacecraft as NASA prepares to travel to the Moon, Mars, and beyond.
NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and aboard the International Space Station, the program investigates how spaceflight affects human bodies and behaviors. Such research drives NASA’s quest to innovate ways that keep astronauts healthy and mission-ready.

NASA’s Parker Solar Probe Snaps Closest-Ever Images to Sun
KEY POINTS
NASA’s Parker Solar Probe has taken the closest ever images to the Sun, captured just 3.8 million miles from the solar surface. The new close-up images show features in the solar wind, the constant stream of electrically charged subatomic particles released by the Sun that rage across the solar system at speeds exceeding 1 million miles an hour. These images, and other data, are helping scientists understand the mysteries of the solar wind, which is essential to understanding its effects at Earth. On its record-breaking pass by the Sun late last year, NASA’s Parker Solar Probe captured stunning new images from within the Sun’s atmosphere. These newly released images — taken closer to the Sun than we’ve ever been before — are helping scientists better understand the Sun’s influence across the solar system, including events that can affect Earth.
“Parker Solar Probe has once again transported us into the dynamic atmosphere of our closest star,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “We are witnessing where space weather threats to Earth begin, with our eyes, not just with models. This new data will help us vastly improve our space weather predictions to ensure the safety of our astronauts and the protection of our technology here on Earth and throughout the solar system.”
Parker Solar Probe started its closest approach to the Sun on Dec. 24, 2024, flying just 3.8 million miles from the solar surface. As it skimmed through the Sun’s outer atmosphere, called the corona, in the days around the perihelion, it collected data with an array of scientific instruments, including the Wide-Field Imager for Solar Probe, or WISPR.

The solar wind expands throughout of the solar system with wide-ranging effects. Together with outbursts of material and magnetic currents from the Sun, it helps generate auroras, strip planetary atmospheres, and induce electric currents that can overwhelm power grids and affect communications at Earth. Understanding the impact of solar wind starts with understanding its origins at the Sun.
The WISPR images give scientists a closer look at what happens to the solar wind shortly after it is released from the corona. The images show the important boundary where the Sun’s magnetic field direction switches from northward to southward, called the heliospheric current sheet. It also captures the collision of multiple coronal mass ejections, or CMEs — large outbursts of charged particles that are a key driver of space weather — for the first time in high resolution.
“In these images, we’re seeing the CMEs basically piling up on top of one another,” said Angelos Vourlidas, the WISPR instrument scientist at the Johns Hopkins Applied Physics Laboratory, which designed, built, and operates the spacecraft in Laurel, Maryland. “We’re using this to figure out how the CMEs merge together, which can be important for space weather.”

This video, made from images taken by Parker Solar Probe’s WISPR instrument during its record-breaking flyby of the Sun on Dec. 25, 2024, shows the solar wind racing out from the Sun’s outer atmosphere, the corona. NASA/Johns Hopkins APL/Naval Research Lab When CMEs collide, their trajectory can change, making it harder to predict where they’ll end up. Their merger can also accelerate charged particles and mix magnetic fields, which makes the CMEs’ effects potentially more dangerous to astronauts and satellites in space and technology on the ground. Parker Solar Probe’s close-up view helps scientists better prepare for such space weather effects at Earth and beyond.
Zooming in on Solar Wind’s Origins
The solar wind was first theorized by preeminent heliophysicist Eugene Parker in 1958. His theories about the solar wind, which were met with criticism at the time, revolutionized how we see our solar system. Prior to Parker Solar Probe’s launch in 2018, NASA and its international partners led missions like Mariner 2, Helios, Ulysses, Wind, and ACE that helped scientists understand the origins of the solar wind — but from a distance. Parker Solar Probe, named in honor of the late scientist, is filling in the gaps of our understanding much closer to the Sun.
At Earth, the solar wind is mostly a consistent breeze, but Parker Solar Probe found it’s anything but at the Sun. When the spacecraft reached within 14.7 million miles from the Sun, it encountered zig-zagging magnetic fields — a feature known as switchbacks. Using Parker Solar Probe’s data, scientists discovered that these switchbacks, which came in clumps, were more common than expected.
When Parker Solar Probe first crossed into the corona about 8 million miles from the Sun’s surface in 2021, it noticed the boundary of the corona was uneven and more complex than previously thought.
As it got even closer, Parker Solar Probe helped scientists pinpoint the origin of switchbacks at patches on the visible surface of the Sun where magnetic funnels form. In 2024 scientists announced that the fast solar wind — one of two main classes of the solar wind — is in part powered by these switchbacks, adding to a 50-year-old mystery.
However, it would take a closer view to understand the slow solar wind, which travels at just 220 miles per second, half the speed of the fast solar wind.
“The big unknown has been: how is the solar wind generated, and how does it manage to escape the Sun’s immense gravitational pull?” said Nour Rawafi, the project scientist for Parker Solar Probe at the Johns Hopkins Applied Physics Laboratory. “Understanding this continuous flow of particles, particularly the slow solar wind, is a major challenge, especially given the diversity in the properties of these streams — but with Parker Solar Probe, we’re closer than ever to uncovering their origins and how they evolve.”
Understanding Slow Solar Wind
The slow solar wind, which is twice as dense and more variable than fast solar wind, is important to study because its interplay with the fast solar wind can create moderately strong solar storm conditions at Earth sometimes rivaling those from CMEs.

This artist’s concept shows a representative state of Earth’s magnetic bubble immersed in the slow solar wind, which averages some 180 to 300 miles per second. NASA’s Goddard Space Flight Center Conceptual Image Lab Prior to Parker Solar Probe, distant observations suggested there are actually two varieties of slow solar wind, distinguished by the orientation or variability of their magnetic fields. One type of slow solar wind, called Alfvénic, has small-scale switchbacks. The second type, called non-Alfvénic, doesn’t show these variations in its magnetic field.
As it spiraled closer to the Sun, Parker Solar Probe confirmed there are indeed two types. Its close-up views are also helping scientists differentiate the origins of the two types, which scientists believe are unique. The non-Alfvénic wind may come off features called helmet streamers — large loops connecting active regions where some particles can heat up enough to escape — whereas Alfvénic wind might originate near coronal holes, or dark, cool regions in the corona.
In its current orbit, bringing the spacecraft just 3.8 million miles from the Sun, Parker Solar Probe will continue to gather additional data during its upcoming passes through the corona to help scientists confirm the slow solar wind’s origins. The next pass comes Sept. 15, 2025.
“We don’t have a final consensus yet, but we have a whole lot of new intriguing data,” said Adam Szabo, Parker Solar Probe mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

On June 14 and 16, technicians installed solar panels onto NASA’s Nancy Grace Roman Space Telescope, one of the final steps in assembling the observatory. Collectively called the Solar Array Sun Shield, these panels will power and shade the observatory, enabling all the mission’s observations and helping keep the instruments cool.

By the end of the year, technicians plan to connect the two halves and complete the Roman observatory. Credit: NASA/Sydney Rohde “At this point, the observatory is about 90% complete,” said Jack Marshall, the Solar Array Sun Shield lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We just need to join two large assemblies, and then we’ll run the whole Roman observatory through a series of tests. We’re currently on track for launch several months earlier than the promised date of no later than May 2027.” The team is working toward launch as early as fall 2026.

Over the course of two days, eight technicians installed Roman's solar panels onto the outer portion of NASA's Nancy Grace Roman Space Telescope. Each of the six panels is about 23 by 33 feet (7 by 10 meters), fitted with photovoltaic cells which will harness energy from sunlight to power the observatory. The solar panels were designed, built, and installed at NASA's Goddard Space Flight Center in Greenbelt, Md.Credit: NASA/Sophia Roberts The Solar Array Sun Shield is made up of six panels, each covered in solar cells. The two central panels will remain fixed to the outer barrel assembly (the observatory’s outer shell) while the other four will deploy once Roman is in space, swinging up to align with the center panels.
The panels will spend the entirety of the mission facing the Sun to provide a steady supply of power to the observatory’s electronics. This orientation will also shade much of the observatory and help keep the instruments cool, which is critical for an infrared observatory. Since infrared light is detectable as heat, excess warmth from the spacecraft’s own components would saturate the detectors and effectively blind the telescope.
The solar panels on NASA’s Nancy Grace Roman Space Telescope are covered in a total of 3,902 solar cells that will convert sunlight directly into electricity much like plants convert sunlight to chemical energy. When tiny bits of light, called photons, strike the cells, some of their energy transfers to electrons within the material. This jolt excites the electrons, which start moving more or jump to higher energy levels. In a solar cell, excited electrons create electricity by breaking free and moving through a circuit, sort of like water flowing through a pipe. The panels are designed to channel that energy to power the observatory.Credit: NASA/Sydney Rohde “Now that the panels have been installed, the outer portion of the Roman observatory is complete,” said Goddard’s Aaron Vigil, a mechanical engineer working on the array. Next, technicians will test deploy the solar panels and the observatory’s “visor” (the deployable aperture cover). The team is also testing the core portion of the observatory, assessing the electronics and conducting a thermal vacuum test to ensure the system operates as planned in the harsh space environment.
This will keep the project on track to connect Roman’s inner and outer segments in November, resulting in a whole observatory by the end of the year that can then undergo pre-launch tests.
Now that the solar panels are installed on the outer portion of NASA’s Nancy Grace Roman Space Telescope, technicians are readying the assembly for vibration testing to ensure it will withstand the extreme shaking experienced during launch.Credit: NASA/Sydney Rohde To virtually tour an interactive version of the telescope, visit: https://roman.gsfc.nasa.gov/interactive/
