NASA's SunRISE mission to study solar storms switches its launch rocket to SpaceX's Falcon Heavy

NASA has switched the SunRISE mission launch vehicle from ULA's Vulcan Centaur to SpaceX's Falcon Heavy.

SunRISE is designed to study solar storms and their effects on satellites and astronauts.

The reason for the change was not disclosed, but it may reflect a preference for a more proven rocket.

The launch vehicle shift could improve confidence in the mission's reliability and schedule.
