Blue Origin preps New Glenn for first booster reflights with NG-3 static fire

Blue Origin fired up its New Glenn rocket in a 19-second static test at Cape Canaveral ahead of NG-3, a mission designed to refly a previously flown booster and push the two-stage vehicle toward its first reflights; the company replaced all seven first-stage engines on the refurbished booster and added upgrades including a thermal protection system on one nozzle, with NG-3 slated to launch Sunday carrying a Block 2 AST SpaceMobile satellite to low Earth orbit.
