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.

The Axiom Mission 4 crew launched on June 25, 2025, aboard a SpaceX Dragon spacecraft to the International Space Station from NASA’s Kennedy Space Center in Florida. From left to right: Tibor Kapu of Hungary, ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla, former NASA astronaut Peggy Whitson, and ESA (European Space Agency) astronaut Sławosz Uznański-Wiśniewski of Poland (Credit: Axiom Space). The NASA-supported fourth private astronaut mission to the International Space Station, Axiom Mission 4, completed its flight as part of the agency’s efforts to demonstrate demand and build operational knowledge for future commercial space stations.
The four-person crew safely returned to Earth, splashing down off the coast of California at 5:31 a.m. EDT on Tuesday, aboard a SpaceX Dragon spacecraft. Teams aboard SpaceX recovery vessels retrieved the spacecraft and astronauts.
Peggy Whitson, former NASA astronaut and director of human spaceflight at Axiom Space, ISRO (Indian Space Research Organization) astronaut Shubhanshu Shukla, and ESA (European Space Agency) project astronaut Sławosz Uznański-Wiśniewski of Poland, and Hungarian to Orbit (HUNOR) astronaut Tibor Kapu of Hungary, completed about two and a half weeks in space.
The Axiom Mission 4 crew launched at 2:31 a.m. on June 25, on a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. Approximately 28 hours later, Dragon docked to the space-facing port of the space station’s Harmony module. The astronauts undocked at 7:15 a.m. on July 14, to begin the trip home.
The crew conducted microgravity research, educational outreach, and commercial activities. The spacecraft will return to Florida for inspection and processing at SpaceX’s refurbishing facilities. Throughout their mission, the astronauts conducted about 60 science experiments, and returned science, including NASA cargo, back to Earth.
A collaboration between NASA and ISRO allowed Axiom Mission 4 to deliver on a commitment highlighted by President Trump and Indian Prime Minister Narendra Modi to send the first ISRO astronaut to the station. The space agencies participated in five joint science investigations and two in-orbit science, technology, engineering, and mathematics demonstrations. NASA and ISRO have a long-standing relationship built on a shared vision to advance scientific knowledge and expand space collaboration.
The private mission also carried the first astronauts from Poland and Hungary to stay aboard the space station.
The International Space Station is a springboard for developing a low Earth orbit economy. NASA’s goal is to achieve a strong economy off the Earth where the agency can purchase services as one of many customers to meet its science and research objectives in microgravity. NASA’s commercial strategy for low Earth orbit provides the government with reliable and safe services at a lower cost, enabling the agency to focus on Artemis missions to the Moon in preparation for Mars while also continuing to use low Earth orbit as a training and proving ground for those deep space missions.

Curiosity Blog, Sols 4595-4596: Just Another Beautiful Day on Mars
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on July 9, 2025 — Sol 4594, or Martian day 4,594 of the Mars Science Laboratory mission — at 11:03:48 UTC. NASA/JPL-Caltech Written by Ashley Stroupe, Mission Operations Engineer at NASA’s Jet Propulsion Laboratory
Earth planning date: Wednesday, July 9, 2025
In today’s plan, we have a little bit of everything. With it being winter still, we are taking advantage of the ability to let the rover sleep in, doing most of the activities in the afternoon when it is warmer and we need less heating. As the Systems Engineer (Engineering Uplink Lead) today, I sequenced the needed heating and some other engineering housekeeping activities.
We start off with an extensive remote science block with Mastcam imaging of a nearby trough to look for potential sand activity. There is color imaging of a displaced block, “Ouro,” near a circular depression — could this be a small crater? Mastcam also takes a look at a ridge “Volcán Peña Blanca” to look at the sedimentary structures, which may provide insights into its formation. ChemCam LIBS and Mastcam team up to look at the “Los Andes” target, which is the dark face of a nearby piece of exposed bedrock. ChemCam RMI and Mastcam check out a distant small outcrop to examine the geometry of the layers. We also throw in environmental observations, a Mastcam solar Tau and a Navcam line-of-site looking at dust in the atmosphere. After a nap, Curiosity will be doing some contact science activities on “Cataratas del Jardín” and “Rio Ivirizu” bedrock targets. Looking at two nearby targets for variability can help us understand the local geology. Cataratas del Jardín gets a brushing to clear away the dust before both targets are examined by MAHLI and APXS. Fortunately for the Arm Rover Planner, both of these targets are fairly flat and easy to reach. Before going to sleep for the night, Curiosity will stow the arm to be ready for driving on the next sol.On the second sol, there is more remote science. ChemCam LIBS and Mastcam will examine “Torotoro,” another piece of layered bedrock. ChemCam RMI will take a mosaic of “Paniri,” which is an interesting incision in the rock that is filled with another material. There are also environmental observations, a Navcam dust devil survey and a suprahorizon movie. After another nap, Curiosity is getting on the road. We’re heading southwest (direction shown in the image) about 50 meters (about 164 feet), but we need to sneak between sandy pits and skirt around some terrain that we can’t see behind. The terrain here provides pretty nice driving, though, without a lot of big boulders, steep slopes, or pointy rocks that can poke holes in our wheels. After the standard post-drive imaging for our next plan, there are some Navcam observations to look for clouds and our normal look under the rover with MARDI before Curiosity goes to sleep for the night.

Curiosity Blog, Sols 4593-4594: Three Layers and a Lot of Structure at Volcán Peña Blanca
NASA’s Mars rover Curiosity used its Mast Camera (Mastcam) to acquire this image showing a part of Volcán Peña Blanca from about 10 meters away (about 33 feet). It is already possible to see the different layers and make out that some of them are parallel, while others are at an angle. Curiosity acquired this image on July 6, 2025 — Sol 4591, or Martian day 4,591 of the Mars Science Laboratory mission — at 10:13:13 UTC. NASA/JPL-Caltech/MSSS Written by Susanne P. Schwenzer, Professor of Planetary Mineralogy at The Open University, UK
Earth planning date: Monday, July 7, 2025
A few planning sols ago, we spotted a small ridge in the landscape ahead of us. Ridges and structures that are prominently raised above the landscape are our main target along this part of Curiosity’s traverse. There are many hypotheses on how they formed, and water is one of the likely culprits involved. That is because water reacts with the original minerals, moves the compounds around and some precipitate as minerals in the pore spaces, which is called “cement” by sedimentologists, and generally known as one mechanism to make a rock harder. It’s not the only one, so the Curiosity science team is after all the details at this time to assess whether water indeed was responsible for the more resistant nature of the ridges. Spotting one that is so clearly raised prominently above the landscape — and in easy reach of the rover, both from the distance but also from the path that leads up to it — was therefore very exciting. In addition, the fact that we get a side view of the structure as well as a top view adds to the team’s ability to read the geologic record of this area. “Outcrops,” as we call those places, are one of the most important tools for any field geologist, including Curiosity and team!
Therefore, the penultimate drive stopped about 10 meters away (about 33 feet) from the structure to get a good assessment of where exactly to direct the rover (see the blog post by my colleague Abby). You can see an example of the images Curiosity took with its Mast Camera above; if you want to see them all, they are on the raw images page (and by the time you go, there may be even more images that we took in today’s plan.
With all the information from the last parking spot, the rover drivers parked Curiosity in perfect operating distance for all instruments. In direct view of the rover was a part of Volcán Peña Blanca that shows several units; this blogger counts at least three — but I am a mineralogist, not a sedimentologist! I am really looking forward to the chemical data we will get in this plan. My sedimentologist colleagues found the different angles of smaller layers in the three bigger layers especially interesting, and will look at the high-resolution images from the MAHLI instrument very closely.
With all that in front of us, Curiosity has a very full plan. APXS will get two measurements, the target “Parinacota” is on the upper part of the outcrop and we can even clean it from the dust with the brush, aka DRT. MAHLI will get close-up images to see finer structures and maybe even individual grains. The second APXS target, called “Wila Willki,” is located in the middle part of the outcrop and will also be documented by MAHLI. The third activity of MAHLI will be a so-called dog’s-eye view of the outcrop. For this, the arm reaches very low down to align MAHLI to directly face the outcrop, to get a view of the structures and even a peek underneath some of the protruding ledges. The team is excitedly anticipating the arrival of those images. Stay tuned; you can also find them in the raw images section as soon as we have them!
ChemCam is joining in with two LIBS targets — the target “Pichu Pichu” is on the upper part of the outcrop, and the target “Tacume” is on the middle part. After this much of close up looks, ChemCam is pointing the RMI to the mid-field to look at another of the raised features in more detail and into the far distance to see the upper contact of the boxwork unit with the next unit above it. Mastcam will first join the close up looks and take a large mosaic to document all the details of Volcán Peña Blanca, and to document the LIBS targets, before looking into the distance at two places where we see small troughs around exposed bedrock.
Of course, there are also atmospheric observations in the plan; it’s aphelion cloud season and dust is always of interest. The latter is regularly monitored by atmosphere opacity experiments, and we keep searching for dust devils to understand where, how and why they form and how they move. Curiosity will be busy, and we are very much looking forward to understanding this interesting feature, which is one piece of the puzzle to understand this area we call the boxwork area.
