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.

NASA, Boeing Update Starliner Orbital Flight Test Date

NASA and Boeing now are targeting no earlier than Friday, April 2, for launch of the agency’s Boeing Orbital Flight Test-2 to the International Space Station.

As preparations continue for the second uncrewed flight test, teams remain focused on the safety and quality of the CST-100 Starliner spacecraft and successful launch of the end-to-end test to prove the system is ready to begin flying astronauts to and from the space station as part of NASA’s Commercial Crew Program.

Teams are adjusting the launch date to allow more time for spacecraft and hardware processing. Ahead of final propellant loading, the company recently replaced avionics units affected as a result of a power surge due to a ground support equipment configuration issue during final checkouts.

“NASA continues to work alongside Boeing to prepare for this first mission of 2021,” said Steve Stich, manager of NASA’s Commercial Crew Program. “The Boeing and NASA teamwork on all aspects of flight preparation including final certification, hazard analysis, and software testing is extraordinary. Even though this uncrewed flight test to the International Space Station is a key milestone on the path to the first Starliner crewed mission planned for later this year, we will fly when we are ready.”

With formal software tests completed, Boeing is continuing with flight preparations. The company is ready to conduct an end-to-end mission rehearsal, using high-fidelity flight hardware and final flight software, to ensure the readiness of the team and combined systems.

Boeing continues to support NASA as it reviews flight readiness, and teams have completed about 95% of the recommendations identified by the joint NASA and Boeing Independent Review Team, formed following the anomalies during the company’s first uncrewed Orbital Flight Test in December 2019.

“We appreciate the significant work NASA is undertaking ahead of launch,” said John Vollmer, Starliner’s vice president and program manager at Boeing. “We’re fully engaged in the agency’s review process as a valuable investment of our time to ensure confidence in the spacecraft.”
