Few people have had the chance to see Earth from house. And for astronauts residing within the Worldwide House Station like Loral O’Hara, that view by no means will get previous.
However there’s nothing like the primary time.
“, you see it in pictures, however that does not examine in any respect to seeing it in individual for the primary time in 3D,” O’Hara informed NPR Quick 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 house — and it was one of the crucial 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 staff 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 adjustments the immune techniques of vegetation.

One in every of these investigations is the Complement of Built-in Protocols for Human Exploration Analysis program, or CIPHER. It goals to assist researchers perceive how residing in house adjustments human well being and psychology.
On Earth, gravity retains blood and different fluids comparatively low within the physique. However when astronauts stay 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 have been congested for a couple of month now and it is not going away, she says. “It is sort 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 in addition for analysis on Earth. For instance, researchers know astronauts lose about 1% to 2% of their bone density per 30 days throughout spaceflight. So, O’Hara and her staff are analyzing bone marrow stem cells with a purpose to higher perceive each this bone loss and regular ageing on Earth.
O’Hara says the adjustments aren’t simply bodily both. She’s even had new sorts of goals since she boarded the ISS final September. She says she usually finds herself in small, tight areas, in search of issues on the house station.
“They don’t seem to be house nightmares, however they don’t seem to be, you already know, nice goals, floating, taking a look at Earth,” she says.
Perhaps at some point an experiment will clarify that, too.
