NASA’s Solar Probe Plus has passed an important design review milestone and can now proceed to assembly and integration in preparation for its scheduled summer 2018 launch date. Currently comprising only a primary structure and propulsion system, the assembly can now move forward with the installation of the remainder of the spacecraft’s systems and science instruments.
Solar Probe Plus is slated to launch atop a United Launch Alliance (ULA) Delta IV Heavy during a 20-day window that opens on July 31, 2018.
