The rollout of the Starliner spacecraft and Atlas V launch vehicle is now targeted for Thursday, July 29 at 8 a.m. EDT.
The delay is due to an internet service provider outage that could not be resolved before the onset of predicted weather exceeding operational constraints. The OFT-2 launch, planned for Friday, July 30, at 2:53 p.m. EDT, remains on track.
Teams from NASA, Boeing and United Launch Alliance completed a launch readiness review on July 27 ahead of NASA’s Boeing Orbital Flight Test-2 mission to the International Space Station. The launch teams still are “go” for launch of Boeing’s CST-100 Starliner spacecraft on a mission to the microgravity laboratory on the company’s second uncrewed flight test.
Launch is scheduled at 2:53 p.m. EDT on Friday, July 30, on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.
At 1 p.m., NASA will host a prelaunch news briefing at the agency’s Kennedy Space Center in Florida. Participants are:
Steve Stich, manager, NASA’s Commercial Crew Program
Joel Montalbano, manager, NASA’s International Space Station Program
John Vollmer, vice president and program manager, Boeing Commercial Crew Program
Gary Wentz, vice president, Government and Commercial Programs, ULA
Jennifer Buchli, deputy chief scientist, NASA’s International Space Station Program
Will Ulrich, launch weather officer, U.S. Space Force, 45th Weather Squadron
For a launch Friday, meteorologists with the U.S. Space Force 45th Weather Squadron are predicting a 40% chance of favorable weather. The primary weather concerns for launch day are the cumulus cloud rule, surface electric rule and lightning rule violations during the instantaneous launch window.
NASA and Boeing are taking another major step on the path to regular human spaceflight launches to the International Space Station on American rockets and spacecraft from American soil with the second uncrewed flight test of Boeing’s CST-100 Starliner as part of the agency’s Commercial Crew Program.
NASA’s Boeing Orbital Flight Test-2 (OFT-2) is targeting launch of the Starliner spacecraft on a United Launch Alliance Atlas V rocket at 2:53 p.m. EDT Friday, July 30, from Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida. Starliner is expected to arrive at the space station for docking about 24 hours later with more than 400 pounds of NASA cargo and crew supplies.
The mission will test the end-to-end capabilities of Starliner from launch to docking, atmospheric re-entry, and a desert landing in the western United States. OFT-2 will provide valuable data that will help NASA certify Boeing’s crew transportation system to carry astronauts to and from the space station.
