Rocket Lab has won a $515 million contract from the U.S. Space Development Agency to build and launch 18 Photon satellites for the Tranche 2 Transport Layer Beta constellation. The spacecraft will form a resilient, low-latency military mesh network in low Earth orbit. This deal builds on the company’s successful Tranche 1 performance and underscores its growing role in national security space programs.
Smartwatches combined with AI detect physiological shifts like elevated heart rate or temperature changes up to 12 hours after infection, potentially cutting pandemic transmission by 50%. Stanford and Texas A&M studies show real promise, yet accuracy varies and devices remain advisory tools rather than diagnostic ones. Physicians emphasize trends over single readings while cautioning against overreliance.
