Space: the final frontier. What’s stopping us from exploring it? Well, lots of things, but one of the major issues is space radiation, and the effects it can have on astronaut health during long voyages. A new review in the open-access journal Frontiers in Cardiovascular Medicine explores what we know about the ways that space radiation can negatively affect cardiovascular health,…

Researchers Finally Measured Radiation Levels On the Moon. They’re High.
Slashdot reader DevNull127 writes: Scientists were able to, for the first time, measure radiation levels on the lunar surface, reports UPI, and nine days ago they published their results: that the radiation levels on the moon are 200 times stronger than on earth — and 2.6 times higher than those on space station. One of the scientists behind the study calls…
First measurements of radiation levels on the moon
In the coming years and decades, several nations are planning to send astronauts to the moon. But on the lunar surface, space radiation poses a significant risk. The Apollo astronauts carried so-called dosimeters with them, which performed rudimentary measurements of the total radiation exposure during their entire expedition to the moon and back again. In the current issue of the journal…
Self-Replicating Chernobyl Mold Tested on ISS as a Space Radiation Shield
Humans on the moon and Mars would face the problem of damaging space radiation. But new research suggests one possible solution to the fact that “Space wants to kill you,” according to CNET:
To protect astronauts, scientists have been studying an unusually hardy organism, discovered in one of the most radioactive places on the planet: Chernobyl… In some parts of the plant,…
Sunlight cracking rocks on Bennu
Asteroids don’t just sit there doing nothing as they orbit the Sun. They get bombarded by meteoroids, blasted by space radiation, and now, for the first time, scientists are seeing evidence that even a little sunshine can wear them down. Source: https://phys.org/news/2020-06-sunlight-bennu.html…
Researchers find clues to how hazardous space radiation begins
Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, satellites and electronic equipment in space. Using data obtained by NASA’s Parker Solar Probe (PSP), researchers observed one of the largest events so far during…
Today in science: Launch of Explorer 1
Can you believe it’s been 62 years since the United States launched its 1st satellite? Explorer 1 advanced the space race between the US and the Soviet Union. It led to the discovery of the Van Allen radiation belts. Source: https://earthsky.org/space/launch-of-explorer-1-jan-31-1958…
Space travel might fry your brain, causing permanent learning and memory problems
During the course of a deep space mission, astronauts are routinely in various degrees of peril. Depending on which Hollywood sci-fi thrillers you choose, these intrepid explorers are at the mercy of malicious aliens, psychotic computers, or collisions with asteroids or space debris. While these might all be possible concerns, remote or otherwise, the greatest real danger to astronauts may in…
