Will asteroid 2024 YR4 hit the Moon?
Asteroid 2024 YR4 made headlines earlier this year when its probability of impacting Earth in 2032 rose as high as 3%. While an Earth impact has now been ruled out, the asteroid’s story continues.
The final glimpse of the asteroid as it faded out of view of humankind’s most powerful telescopes left it with a 4% chance of colliding with the Moon on 22 December 2032.
The likelihood of a lunar impact will now remain stable until the asteroid returns to view in mid-2028. In this FAQ, find out why we are left with this lingering uncertainty and how ESA's planned NEOMIR space telescope will help us avoid similar situations in the future.
A fast radio burst detected last year turned out to be from long-dead NASA satellite
A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant source, but from one circling the planet—a long-dead satellite. The team has posted a paper outlining their findings on the arXiv preprint server.
A Framework To Ensure Lunar Resources Are Available To All
Space exploration enthusiasts tend to overlook the regulatory aspects of their desired goals. They focus on technologies and the science we can do with them rather than mundane things like property rights or environmental considerations. However, in the long run, those enthusiasts will have to grapple with all aspects of exploration programs as they begin to affect more and more of the public. With such foresight, various groups have started putting forward ideas for frameworks of how to holistically think about how to utilize the Moon, as that seems the most likely first stepping stone out to the wider solar system. A new paper from Ekaterina Seltikova and her colleagues at the Space Generation Advisory Council (SGAC) and the University of Toronto puts forth one such framework, with a particular focus on how to develop a lunar economy that is open for everyone.
