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 will hold a joint media teleconference at noon EDT on Tuesday, May 3, to discuss the agency’s Boeing Orbital Flight Test (OFT-2) mission and provide an update on spacecraft readiness.
The teleconference includes the following participants:
Kathryn Lueders, associate administrator, Space Operations Mission Directorate, NASA Headquarters
Steve Stich, manager, Commercial Crew Program, NASA’s Kennedy Space Center in Florida
Joel Montalbano, manager, International Space Station Program, NASA’s Johnson Space Center in Houston
Michelle Parker, vice president and deputy general manager, Space and Launch, Boeing
Mark Nappi, vice president and program manager, CST-100 Starliner, Boeing
OFT-2 is scheduled to launch on Thursday, May 19, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Boeing’s uncrewed CST-100 Starliner will launch atop a United Launch Alliance Atlas V rocket for its flight test to the International Space Station as part of NASA’s Commercial Crew Program.
Starliner is expected to arrive at the space station for docking about 24 hours later with more than 500 pounds of NASA cargo and crew supplies. After a successful docking, Starliner will spend five to 10 days aboard the orbiting laboratory before returning to Earth in the western United States. The spacecraft will return with nearly 600 pounds of cargo, including reusable Nitrogen Oxygen Recharge System (NORS) tanks that provide breathable air to station crew members.
Media wishing to participate in the OFT-2 mission overview news teleconference must RSVP by 11 a.m., Tuesday, May 3, by emailing the Kennedy newsroom at firstname.lastname@example.org.
NASA and Boeing have decided to stand down from Friday’s launch attempt of the agency’s Orbital Flight Test-2 mission. Currently, launch teams are assessing the next available opportunity. The move allows the International 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.
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.
We asked our virtual guests what they would take with them as a zero-gravity indicator if they were launching on the Boeing Starliner spacecraft on July 30 for NASA’s Boeing Orbital Flight Test-2 mission. More than 2,600 of you responded. Two large categories of items emerged: stuffed animals and balls.
Nearly 10% of people suggested something stuffed. This is a traditional category for zero-gravity indicators. Some guests suggested very specific stuffed animals – Snoopy, Baby Yoda, Fiona the hippo from the Cincinnati Zoo, or a something that had been in their family for multiple generations.
We don’t know where they’re shopping, but a few guests suggested stuffed people, Tory Bruno of United Launch Alliance, Jeff Goldblum, and Patrick Star from Sponge Bob fame to be exact. One guest had the lovely idea that “stuffed animals of some sort that would then be donated to sick children.”
Another 10% of respondents suggested some type of ball – or every type of ball. There were tennis balls, baseballs, bouncy balls, disco balls, cannon balls, and balls of yarn. There was the very specific Euro 2020 official football. Finally, there was a handful of very wise respondents packing stress balls.
Water was another frequent suggestion – sometimes with a goldfish in it for good measure, sometimes with an eye toward drinking it if need be! Balloons, books, and M&M’s also were mentioned in multiples. The few suggestions of glitter would no doubt be to the consternation of Starliner engineers! One guest hurt our heads by suggesting “a toy Starliner with a smaller Starliner inside the toy, and to check for zero gravity we look inside the toy to see if the smaller Starliner is floating.”
Our favorite suggestion? A clear cube containing everyone’s name on a card who registered for the event. We’d have trouble fitting the more than 13,000 of you there! But we love the thought.
We’d love to have you along for the next virtual guest program – you can join our standing list or register for specific upcoming missions by visiting nasa.gov/virtualguest. In addition to sharing their thoughts on a launch-related question, virtual guests receive emails with curated launch resources, notifications about NASA activities, and updates on any launch time or date changes.
Whether it’s your first stamp or your eighth, NASA hopes you’ll print, fold, and get ready to fill your virtual passport. Stamps will be emailed following docking to all virtual attendees who registered by email.
Liftoff of the United Launch Alliance Atlas V rocket with Starliner is targeted for 2:53 p.m. EDT Friday, July 30, from Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.
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.
