Boeing’s Starliner spacecraft on the United Launch Alliance (ULA) Atlas V rocket was rolled back from the launch pad at Cape Canaveral Space Force Station in Florida to ULA’s nearby Vertical Integration Facility on July 30 to avoid potential inclement weather in advance of Orbital Flight Test-2’s (OFT-2) launch to the International Space Station.
NASA and Boeing agreed to stand down from the July 30 attempt to allow the space station team time to continue working checkouts of the newly arrived Roscosmos’ Nauka module and to ensure the station will be ready for Starliner’s arrival. The earliest possible launch opportunity to the space station is no earlier than 1:20 p.m. EDT Tuesday, Aug. 3, from Space Launch Complex-41.
The U.S. Space Force 45th Weather Squadron predicts a 60% chance of favorable conditions for the Aug. 3 launch opportunity with the cumulous cloud rule, surface electric fields rule, and the lighting rule as the primary weather concerns.
The OFT-2 mission for NASA’s Commercial Crew Program will test the end-to-end capabilities of Starliner from launch to docking to a return to Earth in the desert of the western United States.
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.
The United Launch Alliance (ULA) Atlas V rocket – set to help write a new chapter in human spaceflight by launching the first flight of the Boeing CST-100 Starliner spacecraft with astronauts to the International Space Station – has arrived at Cape Canaveral in Florida.
The Atlas V will launch NASA astronauts Barry “Butch” Wilmore, Mike Fincke and Nicole Mann on Boeing’s Crew Flight Test (CFT) to demonstrate the ability of the Atlas V and Starliner to safely carry astronauts to and from the space station as part of the agency’s Commercial Crew Program. CFT is targeted for later this year after successful completion of Starliner’s second uncrewed mission, Orbital Flight Test-2, which is targeted to launch on July 30 from Space Launch Complex-41 at Cape Canaveral Space Force Station.
The rocket-delivery ship, called R/S RocketShip, transported the Atlas V first stage and the Dual Engine Centaur upper stage from ULA’s manufacturing facility in Decatur, Alabama, to Cape Canaveral Space Force Station. RocketShip set sail on June 14, arrived June 20, and the Atlas V was unloaded June 21.
Now at the Cape, the Atlas V will undergo receiving checks at the Atlas Spaceflight Operations Center and await the start of operations to prepare for the flight, which will send the three astronauts to the space station. The crewmates are working closely with Boeing to develop the new spacecraft systems, which will provide round-trip crew transportation services to the space station and low-Earth orbit.
