A faulty valve on the Atlas V rocket prevented liftoff May 6, then engineers discovered a helium leak on the Starliner capsule itself. After several weeks of troubleshooting, NASA and Boeing officials decided to proceed with another launch attempt Saturday.<\/p>\n<p>Everything seemed to be coming together for Boeing\u2019s long-delayed crew test flight until a computer problem triggered an automatic hold in the countdown less than four minutes before liftoff. Technicians from United Launch Alliance (ULA), the Atlas V rocket\u2019s builder and operator, traced the problem to a failed power distribution source connected to a ground computer responsible for controlling the final phase of the countdown.<\/p>\n<p>The instantaneous launch opportunity Wednesday is set for 10:52 am EDT (14:52 UTC), when the launch site at Cape Canaveral passes underneath the space station\u2019s orbital plane. Forecasters predict a 90 percent chance of good weather for launch. You can watch NASA\u2019s live coverage in the video embedded below.<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/HneVxAmYcaA?si=DsZUXzxNvkWkvjNI\" width=\"678\" height=\"381\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\">\ufeff<\/iframe><\/p>\n<p>The countdown began late Tuesday night with the power-up of the Atlas V rocket, which was set to be filled with cryogenic liquid hydrogen and liquid oxygen propellants around 5 am EDT (09:00 UTC). Kerosene fuel was loaded into the Atlas V\u2019s first-stage booster prior to the mission\u2019s first launch attempt in early May.<\/p>\n<p>The two Starliner astronauts departed crew quarters at NASA\u2019s Kennedy Space Center for the 20-minute drive to the launch pad, where they arrived shortly before 8 am EDT (12:00 UTC) to climb into their seats inside the Starliner capsule. After pressure checks of the astronauts\u2019 suits and Starliner\u2019s crew cabin, ground teams will evacuate the pad about an hour before launch.<\/p>\n<p>,<\/p>\n<p>Assuming all systems are \u201cgo\u201d for launch, the Atlas V will ignite its Russian-made RD-180 main engine and two solid-fueled boosters to vault away from Cape Canaveral and head northeast over the Atlantic Ocean. Wilmore and Williams will be not only the first people to fly in space on Boeing\u2019s Starliner, but also the first astronauts to ride on an Atlas V rocket, which has flown 99 times before with satellites for the US military, NASA, and commercial customers.<\/p>\n<p>The rocket\u2019s Centaur upper stage will deploy Starliner into space around 15 minutes after liftoff. A critical burn by Starliner\u2019s engines will happen around 31 minutes into the flight to finish the task of placing it into low-Earth orbit, setting it up for an automated docking at the International Space Station at 12:15 pm EDT (16:15 UTC) Thursday.<\/p>\n<p>The two-person crew will stay on the station for at least a week, although a mission extension is likely if the mission is going well. Officials may decide to extend the mission to complete more tests or to wait for optimal weather conditions at Starliner\u2019s primary and backup landing sites in New Mexico and Arizona. When weather conditions look favorable, Starliner will undock from the space station and head for landing under parachutes.<\/p>\n<p>The crew test flight is a prerequisite to Boeing\u2019s crew capsule becoming operational for NASA, which awarded multibillion-dollar commercial crew contracts to Boeing and SpaceX in 2014. SpaceX\u2019s Crew Dragon started flying astronauts in 2020, while Boeing\u2019s project has been stricken by years of delays.<\/p>\n<p>Wilmore and Williams, both former US Navy test pilots, will take over manual control of Starliner at several points during the test flight. They will evaluate the spacecraft\u2019s flying characteristics and accommodations for future flights, which will carry four astronauts at a time rather than two.<\/p>\n<p>\u201cThe expectation from the media should not be perfection,\u201d Wilmore told Ars earlier this year. \u201cThis is a test flight. Flying and operating in space is hard. It\u2019s really hard, and we\u2019re going to find some stuff. That\u2019s expected. It\u2019s the first flight where we are integrating the full capabilities of this spacecraft.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fresh off repairs at the launch pad in Florida, United Launch Alliance engineers restarted the countdown overnight for the third attempt to send an Atlas V rocket and Boeing\u2019s Starliner spacecraft on a test flight to the International Space Station.
