Starliner Rolls out to Launch Pad for Friday’s Planned Liftoff

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.

This morning, July 29, Boeing’s CST-100 Starliner spacecraft and the United Launch Alliance (ULA) Atlas V rocket rolled out of the ULA Vertical Integration Facility to the launch pad at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida ahead of NASA’s Boeing Orbital Flight Test-2 mission to the International Space Station. Liftoff is scheduled for 2:53 p.m. EDT on Friday, July 30.

Current weather shows a 50 percent chance of favorable conditions. Cumulous clouds, surface electricity, and lightning remain the primary concerns for the instantaneous launch window.

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.

NASA will host two briefings on Thursday, July 29, in advance of the mission. Participants include NASA Administrator Bill Nelson, agency leaders, as well as the crew of Boeing’s Crew Flight Test, the mission that will follow the OFT-2 mission. NASA TV launch coverage begins at 2 p.m. on Friday, July 30, and will provide continuous coverage through Starliner orbital insertion.

Starliner Spacecraft Rollout Targeted for Thursday Morning

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.

NASA’s Boeing Orbital Flight Test-2 Mission Remains on Target

The Boeing CST-100 Starliner spacecraft to be flown on Orbital Flight Test-2 (OFT-2) is seen in the Commercial Crew and Cargo Processing Facility at NASA’s Kennedy Space Center in Florida on June 2. Part of the agency’s Commercial Crew Program, OFT-2 is a critical developmental milestone on the company’s path to fly crew missions for NASA. Photo credit: Boeing

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.
