New Frontiers: U.S. Space Force, Zenno, and SpaceX Propel the Next Era of Space Innovation

The US Space Force is making headlines by awarding contracts to Viasat and Intelsat for new anti-jam communication satellites. These are part of a program to develop a jam-resistant satellite communication fleet, and it’s a pretty big investment—we’re talking hundreds of millions of dollars.On a global scale, there's some exciting news from Zenno Astronautics—they've become the first company to operate a superconducting product in space, which is a huge leap for space infrastructure technology.And if we zoom in a bit, there’s also a lot of buzz around SpaceX and its recent IPO. The company's shares have been soaring, and it’s causing a lot of excitement in the market.It’s definitely an exciting time in space industry! 

Astrophysicists construct approximations for the metric of spherically symmetric black holes

RUDN astrophysicists have proposed a new method for approximate calculation of the parameters of spherically symmetric black holes in the Einstein-Maxwell theory. By comparing the shadow radii of the black holes obtained via this method with exact numerical solutions, astrophysicists have revealed that the approximation they suggested shows a reasonable accuracy in the second order. This means that it is possible to study the black holes themselves and the phenomena in their vicinity, for example, particle motion. The article is published in the journal Physical Review D.
