Virgin Galactic is developing a rocket more powerful than LauncherOne to fulfill a recent order for 39 launches from its global satellite Internet partner OneWeb, according to sources familiar with the program.
LauncherTwo will use Virgin Galactic’s largest liquid fuel engine, NewtonThree, in its first stage, according to sources that insisted upon anonymity. A new engine, NewtonFour, will be developed for the second stage.
