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!

Risk from solar flares to planes is real but not worth costly mitigation

Aviation guidelines aim to mitigate the effects of radiation, mainly caused by galactic cosmic rays and solar energetic particles, or SEP. The fluxes in the former are stable and predictable: dose rates are no higher than 10 µSv/h at the normal flight altitude of 12 km. But in the case of SEP, does the frequency of detected solar flares justify the costs of countermeasures? Current mitigation procedures instruct planes to lower altitude or change or cancel flight paths altogether, significantly raising expenses.
