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! 

Old at heart: A solution to red giants' age paradox

Four years ago, several red giant stars were discovered to pose a paradox: even though they are built from very old stellar material, their large masses indicate a clearly younger age. Scientists from the Max Planck Institute for Solar System Research (Germany), Aarhus University (Denmark), and The Ohio State University (U.S.) have now solved the apparent contradiction. For the first time, they investigated the abundances of carbon, nitrogen, and oxygen swirled from the nuclei of these stars to their surfaces. This allows for an indirect look at processes deep within. Several of the investigated red giants must have merged with others during an advanced stage of stellar evolution, the researchers conclude. In these cases, mass is not a suitable criterion for age determination; the stars are indeed old.
