Boeing’s CST-100 Starliner crew ship approaches the International Space Station on the company’s Orbital Flight Test-2 mission before automatically docking to the Harmony module’s forward port. NASA will provide live coverage of prelaunch and launch activities for the agency’s Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.
Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 12:25 p.m. EDT Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the forward-facing port of the station’s Harmony module at approximately 1:50 p.m., Sunday, June 2.
Wilmore and Williams will remain at the space station for about a week to test the Starliner spacecraft and its subsystems before NASA works to complete final certification of the transportation system for rotational missions to the orbiting laboratory as part of the agency’s Commercial Crew Program.
NASA, Boeing, and ULA scrubbed the previous launch opportunity on May 6 due to a suspect oxygen relief valve on the Atlas V rocket’s Centaur second stage. Since, teams have removed and replaced the valve, and completed an assessment of Starliner’s performance and redundancy after discovering a small helium leak in the spacecraft’s service module.
As part of the helium leak investigation, NASA and Boeing conducted a follow-on propulsion system assessment to understand potential helium system impacts to some Starliner return scenarios. NASA also completed a Delta-Agency Flight Test Readiness Review on May 29 to evaluate all work performed and flight rationale before proceeding toward launch.

Audio Only Coverage
Audio only of the news conferences and launch coverage will be carried on the NASA “V” circuits, which may be accessed by dialing 321-867-1220, -1240 or -7135. On launch day, “mission audio,” countdown activities without NASA Television launch commentary, will be carried on 321-867-7135.
Launch audio also will be available on Launch Information Service and Amateur Television System’s VHF radio frequency 146.940 MHz and KSC Amateur Radio Club’s UHF radio frequency 444.925 MHz, FM mode, heard within Brevard County on the Space Coast.
Live Video Coverage Prior to Launch
NASA will provide a live video feed of Space Launch Complex-41 approximately 48 hours prior to the planned liftoff of the mission. Pending unlikely technical issues, the feed will be uninterrupted until the prelaunch broadcast begins on NASA Television, approximately four hours prior to launch. Once the feed is live, find it on NASA Kennedy’s YouTube: http://youtube.com/kscnewsroom.
NASA Website Launch Coverage
Launch day coverage of the mission will be available on the agency’s website. Coverage will include live streaming and blog updates beginning no earlier than 8:15 a.m., June 1, as the countdown milestones occur.

NASA’s Commercial Crew Program has delivered on its goal of safe, reliable, and cost-effective transportation to and from the International Space Station from the United States through a partnership with American private industry. This partnership is changing the arc of human spaceflight history by opening access to low-Earth orbit and the International Space Station to more people, science, and commercial opportunities. The space station remains the springboard to NASA’s next great leap in space exploration, including future missions to the Moon and, eventually, to Mars.
