RocketMotorTwo is the hybrid engine that powered Virgin Galactic’s SpaceShipTwo, called VSS Unity, into space for the first time on December 13, 2018. This historic flight showcased Virgin Galactic’s newest vehicle, capable of carrying up to six passengers into space. RocketMotorTwo will eventually be displayed in the Futures of Space exhibition, scheduled to open in 2025 as part of the museum’s seven-year renovation.
