Meteorologists with the U.S. Space Force 45th Weather Squadron now predict an 80% chance of favorable weather for today’s uncrewed launch of NASA’s Boeing Orbital Flight Test-2 (OFT-2) to the International Space Station. Liftoff is scheduled for 6:54 p.m. EDT from Cape Canaveral Space Force Station in Florida.
The primary weather concerns for launch day are the cumulus and anvil cloud rules violations during the instantaneous launch window.
Boeing’s CST-100 Starliner spacecraft, atop a United Launch Alliance Atlas V rocket, will lift off from Space Launch Complex-41. Live launch coverage begins at 6 p.m. EDT on NASA TV, the NASA app, and the agency’s website.
On Wednesday, May 4, Boeing’s CST-100 Starliner was joined with the rocket that will launch the spacecraft on its way to the International Space Station on an uncrewed flight test for NASA’s Commercial Crew Program.
During the operation, Starliner rolled out of the Commercial Crew and Cargo Processing Facility (C3PF) at NASA’s Kennedy Space Center in Florida and made its way to Space Launch Complex-41 (SLC-41) at Cape Canaveral Space Force Station in preparation for the company’s second uncrewed Orbital Flight Test (OFT-2)
Starliner was raised and carefully placed onto the rocket and now is fully assembled and ready for an integrated systems test, a tip-to-tail electrical check of the 172-foot-tall Atlas V and Starliner stack.
OFT-2 is scheduled to launch Thursday, May 19, to demonstrate the system’s human transportation capabilities.
About 24 hours after launch, Starliner will rendezvous and dock to the space station and then return to Earth five to 10 days later. The test is the last flight before the Starliner system launches American astronauts on the Crew Flight Test (CFT) to the microgravity laboratory – the spacecraft’s first flight test with crew on board. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.

NASA and Boeing continue making progress toward the agency’s upcoming Starliner Orbital Flight Test-2 (OFT-2) mission to the International Space Station as part of NASA’s Commercial Crew Program.
Teams recently completed offloading fuel from the OFT-2 spacecraft inside Starliner’s production factory at NASA’s Kennedy Space Center in Florida in preparation for separating and replacing the current service module (SM2) from the crew module.
“The Starliner team and successful completion of the spacecraft’s development phase are critical to sustaining International Space Station operations through 2030,” said Steve Stich, manager, NASA Commercial Crew Program. “The team’s dedication to developing effective remedies and corrective action after our first OFT-2 launch attempt demonstrates their continued commitment to safely flying NASA crews for years to come.”
In December, Boeing decided to move up service modules currently in production for its upcoming uncrewed and crewed flight tests. The service module originally planned for the Crew Flight Test (CFT) is now being used for OFT-2, and the service module originally planned for Starliner’s first post-certification mission, Starliner-1, now will be used for CFT.
With fuel offload complete, the spacecraft was moved out of the hazardous processing area and into the production factory high bay.
“Because this is not an operation that we normally perform, our team took the time to fully coordinate and assess the proper spacecraft and ground support equipment configurations, and then execute to plan to ensure the safety of our team,” said John Vollmer, vice president and program manager, Boeing’s Commercial Crew Program.
Once separated in the coming weeks from the OFT-2 crew module, SM2 will be sent to NASA’s White Sands Test Facility in New Mexico for additional testing related to the issue affecting the spacecraft’s oxidizer isolation valves.
The investigation into the valve issue continues to substantiate that the most probable cause is interaction of moisture with nitrogen tetroxide that permeates through the Teflon seal in the valve, leading to corrosion. Testing continues to fully understand how this occurrence affects the valves in various environments.
Tests include environmental seal evaluation and exposing valves, in a controlled setting, to temperatures and conditions similar to those the spacecraft experienced prior to the planned launch of OFT-2. The results of these tests will help in the ongoing development of remediation efforts to prevent similar issues on future service modules.
For example, the team designed a purging system that will be integrated into the spacecraft to protect the valves from potential exposure to moisture at the factory, launch complex, and launch pad.
Progress also continues with production of the new service module (SM4) that will go onto the OFT-2 crew module. That service module was recently moved from the low bay production area to the factory’s hazardous processing area for high pressure leak testing. Remaining tasks before mating this service module with the OFT-2 crew module include acceptance testing, final wire harness mating, installation of solar array panels, and final closeouts.
NASA and Boeing continue to work toward an opening in United Launch Alliance’s launch window availability in May for OFT-2. An actual launch date will be determined closer to spacecraft readiness, and with consideration of Eastern Range and International Space Station availability. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.
Teams from NASA, Boeing and United Launch Alliance are “go” for a launch following today’s launch readiness review ahead of the Orbital Flight Test mission to the International Space Station for NASA’s Commercial Crew Program.
Launch is scheduled for 6:36 a.m. EST Friday, Dec. 20, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
Meteorologists with the U.S. Air Force 45th Space Wing continue to predict an 80% chance of favorable weather with the primary concerns for launch day are the Cumulus Cloud Rule and User Ground Winds violations during the instantaneous launch window.

NASA and Boeing are holding a Flight Readiness Review (FRR) today at the agency’s Kennedy Space Center in Florida in preparation for Boeing’s uncrewed Orbital Flight Test as part of NASA’s Commercial Crew Program. The review provides NASA and Boeing the opportunity to assess the mission status and work that needs to be completed prior to the critical flight test.
Ken Bowersox, deputy associate administrator for Human Exploration and Operations at NASA Headquarters, is leading the meeting. The senior Boeing official at the review is Jim Chilton, senior vice president, Boeing Space and Launch.
Teams have gathered from across the agency and Boeing to hear presentations from key mission managers. The FRR is an in-depth assessment on the readiness of flight for Boeing’s CST-100 Starliner spacecraft and systems, mission operations, support functions and readiness of the space station program to support Starliner’s maiden mission to the International Space Station. The meeting will conclude with a poll of all members of the review board.
Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida to rendezvous and dock with the orbiting laboratory. Launch is targeted for Friday, Dec. 20.
The flight test will provide valuable data NASA will review as part of the process to certify Boeing’s crew transportation system is as safe as possible for carrying astronauts to and from the space station.
NASA and Boeing are preparing for the next step in NASA’s Commercial Crew Program on Thursday, Nov. 21, as the CST-100 Starliner spacecraft begins its transport for integration on a United Launch Alliance (ULA) Atlas V rocket ahead of Boeing’s uncrewed Orbital Flight Test to the International Space Station.
During the operation, the fueled Starliner will be moved from Boeing’s Commercial Crew and Cargo Processing Facility at Kennedy to ULA’s Space Launch Complex 41 Vertical Integration Facility on Cape Canaveral Air Force Station. Later the same day, the spacecraft will be stacked on top of an Atlas V rocket for final processing ahead of the launch.
Boeing’s uncrewed flight test, which is targeted for Dec. 17, will provide valuable data on the end-to-end performance of the rocket, spacecraft and ground systems, as well as, in-orbit and landing operations. The data will be used toward certification of Boeing’s crew transportation system for carrying astronauts to and from the space station.
NASA’s Commercial Crew Program is working with the American aerospace industry through public-private partnerships to launch astronauts on American rockets and spacecraft from American soil for the first time since 2011. The goal of the program is safe, reliable and cost-effective human space transportation to and from the International Space Station. This could allow for additional research time aboard the station and increase the opportunity for discovery aboard humanity’s testbed for exploration, which includes sending astronauts to the Moon and Mars.
The United Launch Alliance (ULA) Atlas V rocket set to launch Boeing’s CST-100 Starliner on its maiden voyage to the International Space Station for NASA’s Commercial Crew Program is ready for the mating of Starliner to the top of the launch vehicle.
On Monday, Nov. 4, the Atlas V’s first stage was lifted to the vertical position inside the Vertical Integration Facility at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, followed by the mating of two solid rocket boosters to the booster. ULA teams then attached the Centaur upper stage and launch vehicle adapter atop the Atlas V first stage.
Boeing’s uncrewed Orbital Flight Test (OFT) mission will rendezvous and dock the Starliner spacecraft with the space station. OFT will help set the stage for Boeing’s Crew Flight Test (CFT), which will carry NASA astronauts Michael Fincke and Nicole Mann, and Boeing astronaut Chris Ferguson to the space station and return them safely home.
As aerospace industry providers Boeing and SpaceX begin to make regular flights to the space station, NASA will continue to advance its mission to go beyond low-Earth orbit and establish a human presence on the Moon with the ultimate goal of sending astronauts to Mars.
