Few people have had the chance to see Earth from area. And for astronauts dwelling within the International Space Station like Loral O’Hara, that view by no means will get outdated.
But there’s nothing like the primary time.
“You know, you see it in pictures, however that does not examine in any respect to seeing it in particular person for the primary time in 3D,” O’Hara instructed NPR Short Wave host Regina G. Barber in a latest interview. “I simply noticed the ocean and the clouds — this blue and white marble towards the blackness of area — and it was one of the lovely issues I’ve ever seen.”
O’Hara is a flight engineer for NASA’s Expedition 70 crew, who launched into area in September 2023. She and her group 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 area adjustments the immune methods of crops.

One of those investigations is the Complement of Integrated Protocols for Human Exploration Research program, or CIPHER. It goals to assist researchers perceive how dwelling in area adjustments human well being and psychology.
On Earth, gravity retains blood and different fluids comparatively low within the physique. But when astronauts reside in microgravity these fluids are pushed up in the direction of the center and coronary heart, which might trigger swelling, congestion and even imaginative and prescient and listening to adjustments.
O’Hara says these adjustments might be disorienting for astronauts — and typically make them really feel sick.
“I’ve been congested for a couple of month now and it is not going away, she says. “It’s type of my new regular.”
Onboard the ISS, O’Hara says astronauts hold 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 per thirty days throughout spaceflight. So, O’Hara and her group are analyzing bone marrow stem cells with a view to higher perceive each this bone loss and regular getting old on Earth.
O’Hara says the adjustments aren’t simply bodily both. She’s even had new varieties of goals since she boarded the ISS final September. She says she typically finds herself in small, tight areas, on the lookout for issues on the area station.
“They’re not area nightmares, however they don’t seem to be, you recognize, nice goals, floating, Earth,” she says.
Maybe someday an experiment will clarify that, too.
