The Starliner OFT-2 mission is scheduled to launch on an Atlas V rocket on May 19th. Liftoff is at 6:54 p.m. The day begins at 2 pm

The mission is an uncrewed test flight to the International Space Station to prove out the Starliners systems before a crewed commercial flight for NASA.

NASA cleared Boeing's Starliner for a planned May 19 launch on Orbital Flight Test-2 (OFT-2), a crucial uncrewed mission to the International Space Station.

The flight readiness review took place on Wednesday. You can read more here.

The OFT-2 was supposed to launch in August of 2021, but technicians discovered that some oxidizer valves were stuck. This issue took about eight months to be solved.

We've determined #Starliner will return to our factory for deeper-level troubleshooting of four propulsion system valves. With @NASA, we've decided to stand down for this launch window to make way for other national priority missions.More: https://t.co/oycWeRz156 pic.twitter.com/UzCZN66451August 13, 2021

The United Launch Alliance Atlas V rocket, which was to be used to launch the Starliner, rolled back into the Vertical Integration Facility at Cape Canaveral Space Force Station to allow technicians to continue their work. Read more.

We're not proceeding with #Starliner launch tomorrow. Our team cycled the Service Module propulsion system valves and is taking time to gather data for next steps. We've ruled out software as a cause for the unexpected position indications.More: https://t.co/2fCrIY7uc8 pic.twitter.com/8dvlfpAOneAugust 4, 2021

Boeing has decided to delay the launch of Starliner after finding a valve that was in the wrong position and not being able to quickly identify the cause of the problem.

John Vollmer, vice president and program manager for Boeing's Commercial Crew Program, said in a statement that they will let the data lead their work.

The story about the launch delay is here.

The launch of the Starliner Orbital Flight Test-2 is scrubbed. There will be more details soon.

The Atlas V rocket has just entered a planned four-hour hold at T-minus four minutes before launch, according to the United Launch Alliance. The hold is to make sure the procedures are perfect. ULA says it plans to practice crew procedures during Orbital Test Flight-2.

The weather forecast for the time of the Atlas V launch with Boeing's Starliner on board stands at 50%, according to the United Launch Alliance. The time is 1720 GMT. The current weather does not pose a threat of lightning for the Blue Team entering the launch pad or for their work at the Space Force Station.

The Atlas V rocket is complete, according to a United Launch Alliance update. The company says the rocket is on track to launch at 1:20 pm. It will depend on the weather.

It is coming soon! United Launch Alliance personnel are filling the rocket's first stage with fuel about 5 hours before lift-off.

NASA astronauts are excited to see Starliner today. They and their colleagues will not be able to give the capsule a spin for themselves until the mission is over. Read more.

The launch delay inside the Vertical Integration Facility delayed the launch of the Atlas V rocket and Starliners. There are photos of their second roll out here.

Boeing said in an update that the Starliner is in launch position on Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida.

There is a new video animation that shows the OFT-2 mission.

After spending the weekend inside in case of bad weather, Starliner and its Atlas V rocket are heading back out to the launch pad.

The 45th Weather Squadron of the U.S. Space Force predicts a 60% chance of favorable weather for liftoff on Tuesday.

NASA officials wrote in an update that the primary weather concerns for launch day are the cumulus cloud rule, lightning rule and thick cloud rule violations.

The launch of the Starliner capsule and Atlas V rocket was delayed until Tuesday because of bad weather expected to hit the Space Coast. You can read more here.

During a news conference, NASA officials said that Starliner will be launched on Tuesday. The time is 1720 GMT. The capsule will arrive at the International Space Station on Wednesday if that launch date holds. Read more.

According to a NASA statement, the Starliner OFT-2 mission has been delayed and a new launch date has been established. Russia's Nauka module briefly tilted the International Space Station by firing its thrusters in an unforeseen maneuver that you can read about here.

We will update with a new launch date as soon as possible.

Boeing officials wrote in a statement that success in spaceflight is achieved by millions of elements coming together and working in perfect harmony. We support NASA on the International Space Station and are ready to launch the Starliner when the time is right.

Boeing just shared a new photo of its Starliner spacecraft inside the Vertical Integration Facility at Cape Canaveral Space Force Station as the Atlas V rocket waits for its delayed roll to the launchpad, now scheduled for 8 a.m. Tomorrow is Thursday, July 29th.

Storms rolled in, so Starliner didn't roll out.

The Atlas V rocket was supposed to be flown to the launchpad this morning, but the launch has been delayed until Thursday at 8 a.m. The sun rises at 1200 GMT.

The internet service provider outage that could not be fixed before predicted weather exceeded operational constraints caused the delay. The OFT-2 launch is scheduled for Friday, July 30. NASA officials wrote in a post that the EDT is on track.

The forecast for Saturday is only 40% favorable, with the primary concerns being the Cumulus Cloud, Surface Electric Fields, and Lightning Rules.

This video from Boeing shows you the plan for the second uncrewed launch of Starliner.

The Starliner OFT-2 mission will have a pre-launch news conference today. The briefings start at 1 p.m. You can watch that live on Space.com, courtesy of NASA TV.
