The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around.NASA NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are headed to the International Space Station for the agency’s SpaceX Crew-9 mission in September. Once on station, these crew members will support scientific investigations that include studies of blood clotting, effects of moisture on plants grown in space, and vision changes in astronauts.
Here are details on some of the work scheduled during the Crew-9 expedition:
Blood cell development in space
Megakaryocytes Orbiting in Outer Space and Near Earth (MeF1) investigates how environmental conditions affect the development and function of megakaryocytes and platelets. Megakaryocytes, large cells found in bone marrow, and platelets, pieces of these cells, play important roles in blood clotting and immune response.
“Understanding the development and function of megakaryocytes and platelets during long-duration spaceflight is crucial to safeguarding the health of astronauts,” said Hansjorg Schwertz, principal investigator, at the University of Utah. “Sending megakaryocyte cell cultures into space offers a unique opportunity to explore their intricate differentiation process. Microgravity also may impact other blood cells, so the insights we gain are likely to enhance our overall comprehension of how spaceflight influences blood cell production.”
Results could provide critical knowledge about the risks of changes in inflammation, immune responses, and clot formation in spaceflight and on the ground.

The Neutron Star Interior Composition Explorer (NICER) telescope on the exterior of the space station measures X-rays emitted by neutron stars and other cosmic objects to help answer questions about matter and gravity.
In May 2023, NICER developed a “light leak” that allows sunlight to interfere with daytime measurements. Special patches designed to cover some of the damage will be installed during a future spacewalk, returning the instrument to around-the-clock operation.
“This will be the fourth science observatory and first X-ray telescope in orbit to be repaired by astronauts,” said principal investigator Keith Gendreau at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In just a year, we diagnosed the problem, designed and tested a solution, and delivered it for launch. The space station team — from managers and safety experts to engineers and astronauts — helped us make it happen. We’re looking forward to getting back to normal science operations.”

Some astronauts experience vision changes, a condition called Spaceflight-Associated Neuro-ocular Syndrome. The B Complex investigation tests whether a daily B vitamin supplement can prevent or mitigate this problem and assesses how genetics may influence individual response.
“We still do not know exactly what causes this syndrome, and not everyone gets it,” said Sara Zwart, principal investigator, at the University of Texas Medical Branch, Houston. “It is likely many factors, and biological variations that make some astronauts more susceptible than others.”
One such variation could be related to a metabolic pathway that requires B vitamins to function properly. Inefficiencies in this pathway can affect the inner lining of blood vessels, resulting in leaks that may contribute to vision changes. Providing B vitamins known to affect blood vessel function positively could minimize issues in genetically at-risk astronauts.
“The concept of this study is based on 13 years of flight and ground research,” Zwart said. “We are excited to finally flight test a low-risk countermeasure that could mitigate the risk on future missions, including those to Mars.”

As people travel farther from Earth for longer, growing food becomes increasingly important. Scientists conducted many plant growth experiments on the space station using its Veggie hardware, including Veg-01B, which demonstrated that ‘Outredgeous’ red romaine lettuce is suitable for crop production in space.
Plant Habitat-07 uses this lettuce to examine how moisture conditions affect the nutritional quality and microbial safety of plants. The Advanced Plant Habitat controls humidity, temperature, air, light, and soil moisture, creating the precise conditions needed for the experiment.
Using a plant known to grow well in space removes a challenging variable from the equation, explained Chad Vanden Bosch, principal investigator at Redwire, and this lettuce also has been proven to be safe to consume when grown in space.
“For crews building a base on the Moon or Mars, tending to plants may be low on their list of responsibilities, so plant growth systems need to be automated,” Bosch said. “Such systems may not always provide the perfect growing conditions, though, so we need to know if plants grown in suboptimal conditions are safe to consume.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A fisheye lens attached to an electronic still camera was used to capture this image of NASA astronaut Don Pettit.NASA Science ideas are everywhere. Some of the greatest discoveries have come from tinkering and toying with new concepts and ideas. NASA astronaut Don Pettit is no stranger to inventing and discovering. During his previous missions, Pettit has contributed to advancements for human space exploration aboard the International Space Station resulting in several published scientific papers and breakthroughs.
Pettit, accompanied by cosmonauts Alexey Ovchinin and Ivan Vagner, will launch to the orbiting laboratory in September 2024. In preparation for his fourth spaceflight, read about previous “science of opportunity” experiments Pettit performed during his free time with materials readily available to the crew or included in his personal kit.
Freezing Ice in Space
Thin ice under polarized light frozen aboard the International Space Station.NASA Have you ever noticed a white bubble inside the ice in your ice tray at home? This is trapped air that accumulates in one area due to gravity. Pettit took this knowledge, access to a -90° Celsius freezer aboard the space station, and an open weekend to figure out how water freezes in microgravity compared to on Earth. This photo uses polarized light to show thin frozen water and the visible differences from the ice we typically freeze here on Earth, providing more insight into physics concepts in microgravity.
Space Cup
NASA astronaut Don Pettit demonstrates how surface tension, wetting, and container shape hold coffee in the space cup.NASA Microgravity affects even the most mundane tasks, like sipping your morning tea. Typically, crews drink beverages from a specially sealed bag with a straw. Using an overhead transparency film, Pettit invented the prototype of the Capillary Beverage, or Space Cup. The cup uses surface tension, wetting, and container shape to mimic the role of gravity in drinking on Earth, making drinking beverages in space easier to consume and showing how discoveries aboard station can be used to design new systems.
Planetary Formation

Astronaut Don Pettit demonstrates a mixture of coffee grounds and sugar sticking together in microgravity to understand planetary formation. NASA Using materials that break into very small particles, such as table salt, sugar, and coffee, Pettit experimented to understand planetary formation. A crucial early step in planet formation is the aggregation or clumping of tiny particles, but scientists do not fully understand this process. Pettit placed different particulate mixtures in plastic bags, filled them with air, thoroughly shook the bags, and observed that the particles clumped within seconds due to what appears to be an electrostatic process. Studying the behavior of tiny particles in microgravity may provide valuable insight into how material composition, density, and turbulence play a role in planetary formation.
Orbital Motion
Charged water particles orbit a knitting needle, showing electrostatic processes in space. NASA Knitting needles made of different materials arrived aboard station as personal crew items. Pettit electrically charged the needles by rubbing each one with paper. Then, he released charged water from a Teflon syringe and observed the water droplets orbit the knitting needle, demonstrating electrostatic orbits in microgravity. The study was later repeated in a simulation that included atmospheric drag, and the 3D motion accurately matched the orbits seen in the space station demonstration. These observations could be analogous to the behavior of charged particles in Earth’s magnetic field and prove useful in designing future spacecraft systems.
Astrophotography

These photos contribute to a database researchers use to understand Earth’s changing landscapes, and this imagery can inspire the public’s interest in human spaceflight.
