The rocket company founded by Amazon multibillionaire Jeff Bezos has successfully landed the first stage of its giant new launch vehicle, in a major challenge to Elon Musk’s SpaceX, which dominates the commercial space industry. Blue Origin’s New Glenn rocket took off from Cape Canaveral Space Force Station on Thursday afternoon carrying a pair of NASA space probes bound for Mars. By successfully landing its booster stage on a drone ship downrange, Blue Origin seeks to dramatically cut the cost of launching satellites to Earth orbit and beyond. That’s central to plans by Jeff Bezos to build a constellation of internet satellites to compete with Elon Musk’s Starlink, which has about 9,000 operational satellites on orbit.
