Teams from NASA, Boeing and United Launch Alliance are "go" for a launch following today's launch readiness review ahead of the Orbital Flight Test mission to the International Space Station for NASA's Commercial Crew Program.

Launch is scheduled for 6:36 a.m. EST Friday, Dec. 20, from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

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

At 2 p.m., NASA will host a prelaunch news briefing at Kennedy Space Center. Participants are:

• Kathy Lueders, manager, NASA Commercial Crew Program
  
• Joel Montalbano, deputy manager, International Space Station Program
  
• John Mulholland, vice president and program manager, Boeing Commercial Crew Program
  
• John Elbon, chief operating officer, United Launch Alliance
  
• Pat Forrester, astronaut office chief, Johnson Space Center
  
• Will Ulrich, launch weather officer, 45th Weather Squadron

OFT and CFT Starliners are nearly identical, but OFT will not have emergency oxygen system for crew (as there is now crew).

OFT also will not have In Flight Abort capability.

Gap between OFT and CFT can't be answered in concrete number of months but will be driven by readiness, how OFT goes, and making sure that's all rolled into certifications.
