Few people have had the chance to see Earth from house. And for astronauts dwelling within the Worldwide House Station like Loral O’Hara, that view by no means will get outdated.
However there’s nothing like the primary time.
“, you see it in images, however that does not examine in any respect to seeing it in individual for the primary time in 3D,” O’Hara advised NPR Brief Wave host Regina G. Barber in a latest interview. “I simply noticed the ocean and the clouds — this blue and white marble in opposition to the blackness of house — and it was one of the stunning issues I’ve ever seen.”
O’Hara is a flight engineer for NASA’s Expedition 70 crew, who launched into house in September 2023. She and her crew spent the final six months researching a spread of subjects: How the human mind and physique adapt to microgravity, 3D-printed human coronary heart tissue and the way house modifications the immune programs of vegetation.

One among these investigations is the Complement of Built-in Protocols for Human Exploration Analysis program, or CIPHER. It goals to assist researchers perceive how dwelling in house modifications human well being and psychology.
On Earth, gravity retains blood and different fluids comparatively low within the physique. However when astronauts reside in microgravity these fluids are pushed up in the direction of the guts and coronary heart, which may trigger swelling, congestion and even imaginative and prescient and listening to modifications.
O’Hara says these modifications might be disorienting for astronauts — and typically make them really feel sick.
“I have been congested for a couple of month now and it isn’t going away, she says. “It is type of my new regular.”
Onboard the ISS, O’Hara says astronauts preserve tabs on these potential well being dangers, performing common eye exams and ultrasounds to gather information.
The hope is to make use of this information not just for microgravity analysis, but additionally for analysis on Earth. For instance, researchers know astronauts lose about 1% to 2% of their bone density monthly throughout spaceflight. So, O’Hara and her crew are analyzing bone marrow stem cells in an effort to higher perceive each this bone loss and regular getting old on Earth.
O’Hara says the modifications aren’t simply bodily both. She’s even had new forms of desires since she boarded the ISS final September. She says she usually finds herself in small, tight areas, on the lookout for issues on the house station.
“They don’t seem to be house nightmares, however they don’t seem to be, , nice desires, floating, taking a look at Earth,” she says.
Perhaps at some point an experiment will clarify that, too.
