Physicists at the Ural Federal University (UrFU, Ekaterinburg, Russia) will print unique magnets, magnetic systems, soft magnetic elements with a 3D printer. Samples made with this printer can be useful in almost any field from medicine to space. For example, it can be used by robotic surgical assistants to unclog arteries and veins or to place stents. According to Aleksey Volegov, associate professor of the Department of magnetism and magnetic nanomaterials at the UrFU, now scientists are deciding which kind of magnets they will start printing first.
These will be magnets based on either samarium or cobalt compounds. They can be used in submarines, at space stations, on ships. That is, in those areas where there are very strong temperature changes and we need magnets with special properties in terms of stability, said Aleksey Volegov. Or it will be simple magnets based on an alloy of neodymium, iron, and boron, which work at normal tem ....

The storms, which consist of brightenings and broadenings of the dawn flank of an oval of auroral activity that encircles Jupiter s poles, evolve in a pattern surprisingly reminiscent of familiar surges in the aurora that undulate across Earth s polar skies, called auroral substorms, according to the authors.
The new study is the first to track the storms from their birth on the nightside of the giant planet through their full evolution. It was published today in ....

Skoltech and MIT researchers identify optimal human landing system architectures to land on the Moon

Credit: Pavel Odinev (Skoltech)
Researchers from Skoltech and the Massachusetts Institute of Technology have analyzed several dozen options to pick the best one in terms of performance and costs for the last mile of a future mission to the Moon - actually delivering astronauts to the lunar surface and back up to the safety of the orbiting lunar station. The paper was published in the journal
Acta Astronautica.
Ever since December 1972, when the crew of Apollo 17 left the lunar surface, humans have been eager to return to the Moon. In 2017, the US government launched the Artemis program, which intends to bring the first woman and the next man to the lunar south pole by 2024. The Artemis mission will use a new orbital platform, dubbed the Lunar Gateway, which is going to be a permanent space station from which reusable modules will bring astronauts back to the Moon. This new approach requires a reanalysis of the optimal landing approaches; the private companies cont ....

LOS ALAMOS, N.M., March 11, 2021 A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data shows that the highest-energy cosmic rays come not from supernovae, but from star clusters. ....

Ideas for future NASA missions searching for extraterrestrial civilizations

A researcher at the Instituto de Astrofísica de Canarias (IAC) is the lead author of a study with proposals for technosignatures -evidence for the use of technology or industrial activity in other parts of the Universe- for future NASA missions. The article, published in the specialized journal
Acta Astronautica, contains the initial conclusions of a meeting of experts in the search for intelligent extraterrestrial life, sponsored by the space agency to gather advice about this topic.
In the article, several ideas are presented to search for technosignatures that would indicate the existence of extraterrestrial civilizations, from the most humdrum, such as the presence of industrial pollution in the atmosphere or large swarms of satellites, to hypothetical gigantic space engineering work, such as heat shields to fend off climate change, or Dyson spheres for optimum use of the light from the local star. So ....
