Advanced Orbital Constellations for Solar Storm Defense

Universe Today - Sun, 06/08/2025 - 6:36pm

Solar storms have the potential to cause catastrophic damage. One that occurred around the end of October 2003 (now called the 2003 Halloween Storm) caused an estimated $27B in damages. That number will only increase as humanity has become more reliant on space-based and electrical infrastructure. However, if we could predict when storms would hit with some accuracy and adjust our use of the technologies that could be affected, we could avoid the worst damage. But, as of now, we don't have such a system that could help predict the types of events that could cause that damage accurately enough. That is where a new Sun activity monitoring system, described in a recent paper by Leonidas Askianakis of the Technical University of Munich, would help.

Advancing Deep Space Travel with Nuclear Propulsion

Universe Today - Sun, 06/08/2025 - 6:36pm

How can fission-powered propulsion help advance deep space exploration, specifically to the outer planets like Jupiter, Saturn, Uranus, and Neptune? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as a pair of researchers from India investigated the financial, logistical, and reliability of using fission power for future deep space missions. This study has the potential to help scientists, engineers, and future astronauts develop next-generation technologies as humanity continues to expand its presence in space.
