Japanese researchers behind the new work... wanted to know how space radiation affects fertility in mammals. Radiation can damage the DNA within cells, causing mutations... Environments on Earth with heavy radiation exposure can cause defects in the offspring of animals.
Space radiation in particular has been a major concern for countries like the U.S. and Japan that have sent many astronauts on lengthy missions into low Earth orbit. Farther space destinations are also on the horizon. NASA and other space agencies are developing systems that could support humans on monthslong journeys to other solar system destinations such as the moon and Mars, and radiation is a big concern.
Researchers freeze-dried mouse sperm samples from 12 mice and sealed them within small lightweight capsules...
The packets were transported to the ISS and stored for different amounts of time. A portion of the samples returned to Earth after nine months in space, another set returned after two years and nine months, and the final set of mice sperm samples came back after five years and 10 months in space.
Once back on Earth, the team...chose to rehydrate the sperm with water, then injected them into fresh mouse ovary cells. After transferring them to female mice, the mothers became pregnant and eventually gave birth to baby mice.
The "space pups" were born healthy and with no defects...

Stupid, worthless study, considering that "space radiation" (aka cosmic rays & solar radiation among geeks & scientists) are overwhelmingly shielded by Earth's magnetosphere, especially in LEO.
I've been consistent in my statements that any attempt to visit Mars with our current technology will be a one way trip, that it's a fool's errand until we transcend chemical rocketry propulsion to both shorten transit time and permit enhanced shielding of deep space radiation.
In the meantime, if they REALLY wanted to learn about cosmic radiation, LEO is the dumbest place to be. Morons.
We need a Moon laboratory for multiple scientific missions, including the study of harvesting H3.
When I was growing up, all the ‘sensible’ people said that we’d never land on the Moon.
I researched this a few years back, but memory is foggy.
IIRC, 24 humans have penetrated the Van Allen Belt to space and have been exposed to not only the trapped particles surrounding the Earth, but cosmic & solar radiation alike.
Not for weeks or months, but merely ‘days’. Researchers are devoid of any data whatsoever on the effects of long term exposure to solar & cosmic radiation, save for the experience of the Apollo missions (the oft-repeated citation, “They didn’t die.”).
From a scientific standpoint, it’s rather pathetic.
I still want to read the protocol and the results.
Do you know how much money was spent on this, and whose money it was?
If they never took before/after sperm counts of the space station crews, they were derelict. But the same limitations apply.
We need to be black on the moon.
I’m all for more Black astronauts...:-)
I’m majorly gobsmacked that this is being reported without any challenge whatsoever, just like ‘climate change’ adherents report all things human-caused.
