NASA, Boeing and United Launch Alliance now are targeting 1:20 p.m. EDT Tuesday, Aug. 3, for launch of the Orbital Flight Test-2 (OFT-2) with the International Space Station ready for the arrival of the Starliner spacecraft. NASA’s live launch coverage begins at 12:30 p.m. Docking is targeted for 1:37 p.m. Wednesday, Aug. 4.

OFT-2, Boeing’s second uncrewed flight, is designed to test the end-to-end capabilities of the new system for NASA’s Commercial Crew Program.

Earliest Launch Opportunity for NASA’s Boeing OFT-2 Mission is Aug. 3

On July 29, 2021, Boeing’s CST-100 Starliner spacecraft and the United Launch Alliance Atlas V rocket rolled out of the Vertical Integration Facility to the launch pad at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. Starliner will launch on the Atlas V for Boeing’s second uncrewed Orbital Flight Test (OFT-2) for NASA’s Commercial Crew Program. OFT-2 is an important uncrewed mission designed to test the end-to-end capabilities of the new system for NASA’s Commercial Crew Program.

NASA and Boeing have elected to stand down from Friday’s launch attempt of the agency’s second Orbital Flight Test (OFT-2) mission. Currently, the earliest available launch opportunity is 1:20 p.m. EDT Tuesday, Aug. 3. The International Space Station team will use the time to continue working checkouts of the newly arrived Roscosmos Nauka multipurpose laboratory module (MLM) and to ensure the station will be ready for Starliner’s arrival.

Launch preparations will resume following a final decision from the International Space Station and Commercial Crew Program teams for the next opportunity to send Starliner on its way to complete the OFT-2 mission, which will set the stage for the first Crew Flight Test.

Earlier Thursday, Starliner atop its United Launch Alliance Atlas V rocket was moved to its seaside launch pad for standard launch preparations. Teams are assessing moving the vehicle back to its Vehicle Integration Facility to protect it from weather until launch preparations resume. Starliner and Atlas V are in a safe, flight-ready configuration and do not require any near-term servicing.

The Atlas V was assembled throughout July, which included the transfer of Starliner from Boeing’s spacecraft processing facility at NASA’s Kennedy Space Center in Florida to nearby Cape Canaveral Space Force Station Launch Complex 41 for mating atop the rocket.
