ULA Conducts Dress Rehearsal for Starliner Launch; Date Slips a Day

The Boeing CST-100 Starliner spacecraft is guided into position above a United Launch Alliance Atlas V rocket at the Vertical Integration Facility at Space Launch Complex 41 at Florida’s Cape Canaveral Air Force Station on Nov. 21, 2019. Starliner will be secured atop the rocket for Boeing’s Orbital Flight Test to the International Space Station for NASA’s Commercial Crew Program. The spacecraft rolled out from Boeing’s Commercial Crew and Cargo Processing Facility at NASA’s Kennedy Space Center earlier in the day.

CAPE CANAVERAL AIR FORCE STATION, Fla., Dec. 6, 2019 (ULA PR) — The launch of the Atlas V rocket carrying Boeing’s Orbital Flight Test (OFT) Starliner spacecraft is now targeted for Dec. 20.

We successfully conducted a wet dress rehearsal (WDR), a critical pre-launch milestone, on Friday, Dec. 6. We were unable to complete the milestone on Thursday, Dec. 5, as planned due to a weather-related launch delay of an International Space Station re-supply mission, which created a range resource conflict. This caused our targeted launch date to shift to the right by one day.

We continue to work closely with Boeing to ensure that the Starliner flies as soon as the spacecraft and launch vehicle are ready.
