NASA’s SpaceX Crew-9 commander Nick Hague is pictured in his flight suit during training at SpaceX headquarters in Hawthorne, California. Hague will perform human health and performance research on the International Space Station as part of his mission.SpaceX NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will soon dock with the International Space Station as part of the agency’s SpaceX Crew-9 mission, a venture which will enhance scientific research and bolster the knowledge about how people can live and work in space.
During the planned five-month mission, Hague’s mission tasks will include participating in a variety of research projects for NASA’s Human Research Program. Each study is designed to help address the health challenges that astronauts may face during future long-duration missions to the Moon, Mars, and beyond.
“Hague’s experiences and research may potentially lead to scientific breakthroughs that may not be possible on Earth,” said Steven Platts, chief scientist for human research at NASA’s Johnson Space Center in Houston.
A major focus for Hague’s time aboard the station is to study the suite of space-related vision disorders called Spaceflight Associated Neuro-ocular Syndrome (SANS) which occur as body fluids shift toward the head in weightlessness. These shifts can cause changes to the eye: the optic nerve can swell, the retina may develop folds, and the back of the eye can even flatten. Earlier research suggests multiple factors contribute to the syndrome, so two vision-related studies on this mission will tackle different yet distinct approaches that may help address or even prevent such changes during future missions.
One project, called Thigh Cuff, will explore whether wearing fitted cuffs could counter the syndrome by keeping more bodily fluids in the legs. Thigh cuffs are compact, lightweight, and easy to use, which makes them appealing for potential use during long-duration, deep space missions.
For this study, Hague will wear the thigh cuffs for six hours during two sessions. To help researchers measure how well the cuffs work, he will record ultrasound images of blood flow in his legs and neck veins during the sessions. Researchers will also compare this data against ultrasounds taken without the cuff to examine flow differences.
“Thigh cuffs like these may allow researchers to better investigate medical conditions that result in extra fluid in the brain or too much blood returning to the heart,” said study leader Brandon Macias at NASA Johnson.
In another study, Hague will test if a vitamin regimen may help combat SANS. The study, led by Sara Zwart, a nutritional biochemist at NASA Johnson, seeks to examine if a daily vitamin B supplement—taken before, during, and after flight—can prevent or mitigate swelling at the back of the eye. The research will also assess how an individual’s genetics may influence the response.
“Earlier research suggests that some people are more susceptible to this ocular syndrome than others based on genetics that can influence B vitamin requirements, so taking daily vitamins may make all the difference,” Zwart said. “We think by giving the B vitamins, we could be taking that piece of genetic variability out of the equation.”
The work also may eventually improve care options for women on Earth with polycystic ovary syndrome, a condition that can cause eye changes and infertility in women. Researchers hope that patients may similarly benefit from targeting the same genetic pathways and vitamin supplementation as crew members in space.
Hague also will record data to study whether a new way of administering a common anti-nausea medicine can help alleviate motion sickness following launch and landing. In this study, Hague can self-administer a novel nasal gel formulation of the medication scopolamine. Hague will note his experiences using this medicine and any other motion sickness aides, including alternative medications or behavioral interventions like specific head movements.
This research, led by neuroscientist Scott Wood of NASA Johnson, eventually will include 48 people.
“Our goal is to understand how to help future space travelers adapt to motion sickness when living and working in space,” Wood said. “Crew members must stay healthy and perform key tasks, including landing on the Moon and other destinations.”
To help NASA plan future missions, Hague also will participate in human research studies that tackle other space challenges, such as avoiding injury upon landing back on Earth and learning how space travel affects the human body on a molecular level.

4 Min Read Robotic Moving ‘Crew’ Preps for Work on Moon
The LANDO system works by using onboard sensors to scan encoded markers (similar to a QR code) on a payload, which will reveal critical information about its position and orientation relative to the LSMS. This information is used to calculate where the robotic arm exists in space and plan the motion path to pick up and move payloads. Credits: NASA/David C. Bowman As NASA moves forward with efforts to establish a long-term presence on the Moon as part of the Artemis campaign, safely moving cargo from landers to the lunar surface is a crucial capability.
Whether the cargo, also known as payloads, are small scientific experiments or large technology to build infrastructure, there won’t be a crew on the Moon to do all the work, which is where robots and new software come in.
A team at NASA’s Langley Research Center in Hampton, Virginia, spent the last couple of years infusing existing robotic hardware with a software system that makes the robot operate autonomously. Earlier this month, that team, led by researcher Dr. Julia Cline of NASA Langley’s Research Directorate, ran demonstrations of their system called LANDO (Lightweight Surface Manipulation System AutoNomy capabilities Development for surface Operations and construction).
LANDO prepares to move its payload to a safe spot on the simulated lunar surface.NASA/David C. Bowman The demos took place in an area set up to look like the Moon’s surface, complete with fake boulders and a model lunar lander. During the first demo, the team placed the payload, a small metal box, on a black pedestal. The robotic arm stretched over the scene, with its dangling hook poised to grasp the box.
As the team huddled nearby around computers, sensors on the arm scanned the surrounding area, looking for the metal box, which was outfitted with encoded markers — similar to QR codes — that revealed critical information about its position and orientation relative to the arm. Using a graphic user interface, team member Amelia Scott also chose a location for LANDO to place the payload.
During a series of slow, methodical movements, LANDO transports a payload from a pedestal to a simulated lunar surface.NASA/Angelique Herring After locating the metal box and computing a safe path to move it, the arm began a slow, deliberate movement toward its target, coming in at a precise angle that allowed the hook to select a capture point on the payload. Once engaged, the arm slowly lifted the payload from the pedestal, moved right, and gently lowered the payload to the simulated lunar surface. With the payload safely on the surface, the system carefully disengaged the hook from the capture point and returned to its home position. The entire process took a few minutes. Shortly after the first demo was complete, the team did it again, but with a small model rover.
“What we demonstrated was the repeatability of the system,moving multiple payloads to show that we’re consistently and safely able to get them from point A to point B,” said Cline. “We also demonstrated the Lightweight Surface Manipulation System hardware – the ability to control the system through space and plan a path around obstacles.”
The system’s successful performance during the September demonstration marks the end of this project, but the first step in developing a larger system to go to the Moon.
Now that the team has determined how the system should function, Cline believes the next natural step would be to develop and test an engineering design unit on one of the landers going to the Moon as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative. The team is actively looking for industry partners who want to commercialize the capability.
Through CLPS, NASA is working with commercial companies to deliver science and technology demonstrations to the Moon.
The work behind LANDO could be directly infused into much larger versions of a lightweight surface manipulation system.

And kneeling, left to right: Amelia Scott, Matthew Vaughan, Julia Cline, Jessica Friz and Javier Puig-Navarro.NASA/Ryan Hill “The overall control system we’ve developed would apply to larger versions of the technology,” said Cline. “When you think about the payloads we’ll have to offload for on the Moon, like habitats and surface power systems, this is the kind of general-purpose tool that could be used for those tasks.”
The LANDO system was funded through the Early Career Initiative in NASA’s Space Technology Mission Directorate (STMD). Through STMD, NASA supports and develops transformative space technologies to enable future missions. As NASA embarks on its next era of exploration with the Artemis campaign, STMD is helping advance technologies, developing new systems, and testing capabilities at the Moon that will be critical for crewed missions to Mars.

NASA astronaut Tracy C. Dyson, along with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub, return to Earth after completing their mission to the International Space Station.Credit: NASA NASA astronaut Tracy C. Dyson completed a six-month research mission aboard the International Space Station on Monday, returning to Earth with Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub.
The trio departed the space station aboard the Soyuz MS-25 spacecraft at 4:36 a.m. EDT Monday, Sept. 23, making a safe, parachute-assisted landing at 7:59 a.m. (4:59 p.m. Kazakhstan time), southeast of the remote town of Dzhezkazgan, Kazakhstan.
While aboard the orbiting laboratory, Dyson conducted multiple scientific and technology activities including the operation of a 3D bioprinter to print cardiac tissue samples, which could advance technology for creating replacement organs and tissues for transplants on Earth. Dyson also participated in the crystallization of model proteins to evaluate the performance of hardware that could be used for pharmaceutical production and ran a program that used student-designed software to control the station’s free-flying robots, inspiring the next generation of innovators.
Dyson launched on March 23 and arrived at the station March 25 alongside Roscosmos cosmonaut Oleg Novitskiy and spaceflight participant Marina Vasilevskaya of Belarus. Novitskiy and Vasilevskaya were aboard the station for 12 days before returning home with NASA astronaut Loral O’Hara on April 6.
Spanning 184 days in space, Dyson’s third spaceflight covered 2,944 orbits of the Earth and a journey of 78 million miles as an Expedition 70/71 flight engineer. Dyson also conducted one spacewalk of 31 minutes, bringing her career total to 23 hours, 20 minutes on four spacewalks.
Kononenko and Chub, who launched with O’Hara to the station on the Soyuz MS-24 spacecraft last September, spent 374 days in space on a trip of 158.6 million miles, spanning 5,984 orbits. Kononenko completed his fifth flight into space, accruing a record of 1,111 days in orbit, and Chub completed his first spaceflight.
Following post-landing medical checks, the crew will return to the recovery staging city in Karaganda, Kazakhstan. Dyson will then board a NASA plane bound for the agency’s Johnson Space Center in Houston.
