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.
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

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.
Engineers in ULA’s Vertical Integration Facility (VIF) used large cranes to assemble the stages of the rocket in an upright position on its mobile launch platform, which will carry the Atlas V and Starliner from the VIF to the pad for launch.
To verify the rocket is ready to launch, technicians will soon power the Atlas V to test flight controls, check the engine steering profiles, and conduct a combined systems test.
The 172-foot-tall rocket will be fully completed when the Starliner is mounted aboard the Atlas V. A ULA payload transporter will move the capsule from Boeing’s Commercial Crew and Cargo Processing Facility (C3PF) at the Kennedy Space Center to the nearby VIF for attachment.
The Atlas V will propel Starliner off the pad on 1.6 million pounds of thrust on its second uncrewed flight test from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida no earlier than July 30.
As Boeing’s second uncrewed flight for NASA’s Commercial Crew Program, OFT-2 will serve as an end-to-end flight test to prove the Atlas V rocket and Starliner are ready for regular missions launching astronauts to and from the space station.
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.
NASA and Boeing are targeting 2:53 pm EDT Friday, July 30, for the launch of the company’s Starliner uncrewed Orbital Flight Test-2 (OFT-2) to the International Space Station. The updated launch target is supported by the station’s visiting vehicle schedule, Starliner readiness, and the availability of the United Launch Alliance Atlas V rocket.
“NASA and Boeing have done an incredible amount of work to get to this point,” said Steve Stich, Commercial Crew Program manager. “Our teams are ready for this important mission due to the coordinated efforts of many, including United Launch Alliance, NASA’s Launch Services Program, and the U.S. Space Force, which enabled us to establish this launch opportunity. We are looking forward to a successful OFT-2 mission.”
Boeing recently completed end-to-end testing of Starliner’s fight software by flying a five-day simulated OFT-2 mission to the station. The company will continue supporting NASA’s post-test reviews. All actions recommended by the NASA-Boeing Joint Independent Review Team following Starliner’s uncrewed first flight test in December 2019 are complete and pending closure by NASA.
Boeing also will continue processing hardware for its first flight of astronauts – the Crew Flight Test – until mid-summer. OFT-2 launch activities, including loading cargo and fueling the spacecraft are scheduled to begin around this time.
A launch on July 30 would lead to rendezvous and docking with the space station on the evening of Saturday, July 31.
NASA’s Commercial Crew Program is working with industry through a public-private partnership to provide safe, reliable, and cost-effective transportation to and from the International Space Station, which will allow for additional research time and will increase the opportunity for discovery aboard humanity’s testbed for exploration. The space station remains the springboard to space exploration, including future missions to the Moon and eventually to Mars.
NASA and SpaceX agreed to move Crew-1’s undocking and splashdown from Wednesday, April 28, following a review of forecast weather conditions in the splashdown zones off the coast of Florida, which currently predict wind speeds above the recovery criteria. Teams will continue to monitor weather conditions for splashdown ahead of Friday’s planned undocking.
The return to Earth – and activities leading up to the return – will air live on NASA Television, the NASA App, and the agency’s website.
In the early morning hours of Tuesday, April 20, teams will complete the final major review for NASA’s SpaceX Crew-2 mission that will launch from the agency’s Kennedy Space Center in Florida to the International Space Station. At the conclusion of the review, called the Launch Readiness Review (LRR), NASA and SpaceX will confirm the target launch time of 6:11 a.m. EDT Thursday, April 22.
About an hour after completion of the LRR, no earlier than 8 a.m., a prelaunch news conference will take place live on NASA Television and the agency’s website. Participants are:
Steve Stich, manager, Commercial Crew Program, Kennedy Space Center
Joel Montalbano, manager, International Space Station, Johnson Space Center
Kirt Costello, chief scientist, International Space Station Program, Johnson
Norm Knight, deputy manager, Flight Operations Directorate, Johnson
Benji Reed, senior director, Human Spaceflight Programs, SpaceX
Junichi Sakai, manager, International Space Station Program, JAXA
Frank de Winne, manager, International Space Station Program, ESA
Brian Cizek, launch weather officer, 45th Weather Squadron, U.S. Space Force

Crew-2 mission astronauts Shane Kimbrough and Megan McArthur of NASA, along with JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet will head to the International Space Station for a six-month science mission in the Crew Dragon spacecraft, which will launch on the SpaceX Falcon 9 rocket from Launch Complex 39A. NASA TV coverage of the launch preparations and lift off will begin at 2 a.m. Thursday, April 22. The Crew Dragon is scheduled to dock to the space station Friday, April 23 at approximately 5:30 a.m. EDT.
Crew-2 is the second crew rotation flight of a U.S. commercial spacecraft with astronauts to the space station and the first carrying two international crew members. The Crew-2 astronauts will join the other members of Expedition 65, NASA astronaut Mark Vande Hei and cosmonauts Oleg Novitskiy and Pyotr Dubrov of Roscosmos, for a six-month mission conducting science experiments in low-Earth orbit. An important scientific focus on this expedition is continuing a series of Tissue Chips in Space studies. Tissue chips are small models of human organs containing multiple cell types that behave much the same as they do in the body. The expedition will conduct other microgravity science investigations as well as complete maintenance and upgrades to the space station.
The U.S. Space Force 45th Weather Squadron predicts an 80% chance of favorable weather conditions at the launch pad for lift off of NASA’s SpaceX Crew-2 mission based on Falcon 9 Crew Dragon launch weather criteria. The primary weather concerns for the launch area will be liftoff winds.
Teams also will monitor weather conditions both for the launch area and downrange for the flight of Crew Dragon.
NASA, SpaceX, and the Crew-1 astronauts aboard the International Space Station marked a milestone Monday with the relocation of Crew Dragon Resilience from one docking port to another, setting the stage for upcoming crew rotation missions and SpaceX’s next cargo flight to the station.
The planned relocation from the station’s Harmony Node 2 forward docking port to its zenith, or space-facing port, is a first for a commercial crew spacecraft, but demonstrates a task very likely to be commonplace in the future.
The move freed the forward docking adapter ahead of NASA’s SpaceX Crew-2 mission, which will deliver the next four astronauts aboard Crew Dragon Endeavour to augment the station’s Expedition 65 crew.
NASA astronauts Shane Kimbrough and Megan McArthur, JAXA (Japan Aerospace Exploration Agency) astronaut Aki Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet are scheduled to launch to the station at 6:11 a.m. Eastern, Thursday, April 22, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida, and arrive at the station the next day at approximately 5:30 a.m. Crew-2 will be the first commercial crew mission to fly two international partner crew members.
After an approximate five-day shift change, Crew-1 NASA astronauts Michael Hopkins, Victor Glover, and Shannon Walker, along with JAXA astronaut Soichi Noguchi, will undock Crew Dragon Resilience at 5 a.m. Wednesday, April 28, and splashdown off the coast of Florida 7.5 hours later at about 12:35 p.m., after 164 days in space. Their return date and time is dependent on having a healthy spacecraft and favorable weather in the selected splashdown zone.
A Dragon cargo spacecraft carrying several tons of supplies and the first set of new solar arrays for the space station on SpaceX’s 22nd commercial cargo resupply mission is targeted to launch Thursday, June 3, and requires the space-facing port position to enable robotic extraction of the arrays from Dragon’s trunk using Canadarm2.
NASA Commercial Crew Program Manager Steve Stich talked with Expedition 64 Flight Engineer Kate Rubins and Hopkins Friday about their mission. He also highlighted the 10th anniversary Monday, April 5, of the public-private partnership that returned the launch of astronauts on American spacecraft from the United States.
NASA and SpaceX are continuing to prepare for the Crew-3 mission, targeted as early as Saturday, Oct. 23, followed by return of Crew-2 no earlier than Sunday, Oct. 31. These target dates allow NASA’s Commercial Crew Program and the station program to schedule future cargo and crew missions as needed to continue sustaining the orbiting laboratory where hardware and science needs are required.
A trio of astronauts were assigned to the Crew-3 mission last December by NASA and ESA to begin training for the planned six-month science mission.
The trio will consist of NASA astronauts Raja Chari and Tom Marshburn, who will serve as commander and pilot, respectively, and ESA astronaut Matthias Maurer, who will serve as a mission specialist. A fourth crew member will be added at a later date, following a review by NASA and its international partners.
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.”
