Good morning from the NASA News Center at Kennedy Space Center in Florida. It’s launch day for Boeing’s CST-100 Starliner spacecraft. The United Launch Alliance Atlas V rocket, with Starliner atop, are poised on the launch pad at nearby Space Launch Complex 41 on Cape Canaveral Air Force Station.

Starliner will make its inaugural flight to the International Space Station, called Orbital Flight Test, as part of NASA’s Commercial Crew Program. Liftoff is scheduled for 6:36 a.m. EST during an instantaneous launch window.

Fueling of the Atlas V rocket began at about 12:30 a.m. today. The first stage booster’s RD-180 engine, containing two thrust chambers, was fueled with Rocket Propellant-1 (RP-1), or highly purified kerosene. The Centaur second stage was fueled with liquid hydrogen and liquid oxygen. Fueling of the rocket was completed about two hours later.

Stay tuned for coverage of the countdown events and launch. Watch the coverage live on NASA TV. More details about the mission and NASA’s Commercial Crew Program can be found in the online press kit and by following the @commercial_crew on Twitter and commercial crew on Facebook.

Meteorologists with the U.S. Air Force 45th Weather Squadron continue to predict an 80% chance of favorable weather for launch early this morning. Primary concerns for launch day are the Cumulus Cloud Rule and User Ground Winds violations during the instantaneous launch window.

Boeing’s CST-100 Starliner spacecraft atop a United Launch Alliance Atlas V rocket rolled out of the Vertical Integration Facility at Cape Canaveral Air Force Station’s Space Launch Complex 41 earlier today. Starliner now stands poised at the launch pad awaiting its maiden flight on Boeing’s uncrewed Orbital Flight Test to the International Space Station as part of NASA’s Commercial Crew Program. Liftoff is scheduled for 6:36 a.m. EST Friday, Dec. 20. The flight test will provide valuable data on the end-to-end performance of the Atlas V rocket, Starliner spacecraft, and ground systems, as well as in-orbit, docking, and landing operations. The data will be used as part of NASA’s process of certifying Boeing’s crew transportation system for carrying astronauts to and from the space station.

When Boeing’s Orbital Flight Test (OFT) launches on Dec. 20, 2019, it will be a major step toward returning human spaceflight capability to the U.S.

The uncrewed mission for NASA’s Commercial Crew Program will rendezvous and dock Boeing’s CST-100 Starliner spacecraft with the International Space Station and return to Earth on Dec. 28. Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.

“This test flight will give us valuable data about Starliner’s performance in the actual environment through each phase of flight and demonstrate its capability to transport crew to the space station and bring them home safely,” said Trip Healey, NASA’s mission manager for OFT. “Being on the cusp of this huge moment in history is really exciting.”

Data from the mission will validate spacecraft system performance and will move Starliner farther down the path toward its first flight with astronauts aboard — Boeing’s Crew Flight Test (CFT).

NASA astronauts Michael Fincke and Nicole Mann and Boeing astronaut Chris Ferguson will be onboard Starliner for CFT. All three were on hand when the spacecraft for this flight test rolled out of Boeing’s Commercial Crew and Cargo Processing Facility at NASA’s Kennedy Space Center in Florida on Nov. 21, making the roughly six mile trek on a transport vehicle to SLC-41 to be mated atop the Atlas V rocket.

NASA and Boeing are proceeding with plans for Boeing’s Orbital Flight Test following a full day of briefings and discussion called a Flight Readiness Review that took place at the agency’s Kennedy Space Center in Florida.

Launch of the CST-100 Starliner spacecraft atop a United Launch Alliance Atlas V rocket is scheduled for 6:36 a.m. EST Friday, Dec. 20, from Space Launch Complex 41 on Cape Canaveral Air Force Station. The uncrewed flight test will be Starliner’s maiden mission to the International Space Station for NASA’s Commercial Crew Program.

NASA is working with its commercial partners to launch astronauts on American rockets and spacecraft from American soil for the first time since 2011. Safe, reliable and cost-effective human transportation to and from the space station will allow for additional research time and increase the opportunity for discovery aboard humanity’s testbed for exploration.

NASA will hold a post-flight readiness review teleconference at 3 p.m. EST for media from Kennedy with the following representatives:

Jim Morhard, NASA Deputy Administrator
Phil McAlister, director, NASA Commercial Spaceflight Development
Kathy Lueders, manager, NASA Commercial Crew Program
Kirk Shireman, manager, International Space Station Program
John Mulholland, vice president and program manager, Boeing Commercial Crew Program
Steve Koerner, director, Flight Operations

Flight Readiness Review Begins for Boeing’s Orbital Flight Test

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.
