[b]Starliner Rollout Preparations Continue[/b] [i]Weight and center-of-gravity operations complete[/i] Following fueling and checkout operations, the Boeing team moved the Crew Flight Test spacecraft out of the Starliner facility's hazardous processing area to a machine that weighs and measures the center of gravity (CG) of the spacecraft. Using the high bay crane, the engineers and technicians lifted Starliner into place and secured it onto the machine. [i][b]Above[/b]: CFT Starliner spacecraft during final weight and CG.[/i] (Boeing) Previous weigh-ins of the Crew Module and Service Module, where the weight and CG machine tilts the elements up to 30 degrees along their principle axes, were taken to get highly accurate measurements of the individual elements. Once mated, loaded with cargo and fueled, a final weight and CG measurement is taken of the completed spacecraft. Through this method, engineers are able to validate an accurate center of gravity of the entire integrated spacecraft, which needs to be within a volume about the size of an American quarter. Accurate weight and CG measurements are critical to the nominal performance of both the entire integrated spacecraft and launch vehicle during ascent and the spacecraft during on-orbit maneuvers and reentry.

The team then secured Starliner to the transporter, where it is now ready for the overnight trek to its launch site, Space Launch Complex-41.
