NASA's Space Launch System (SLS) rocket returns to the Vehicle Assembly Building.
The 322-foot-tall rocket rolled back from Launch Complex 39B on Wednesday, February 25, into the VAB in order to assess a helium flow issue that cropped up with the Interim Cryogenic Propulsion Stage (ICPS). This issue became known after an otherwise successful wet dress rehearsal tanking test of the rocket on February 19.
This video, comprised mostly of video shot by Spaceflight Now, captures the roughly 11.5-hour rollback in a roughly 11.5 minutes timelapse.
