Boeing attempts a second test flight of an unmanned spacecraft to the ISS

This NASA photo shows the United Launch Alliance Atlas V rocket with the Boeing CST-100 Starliner spacecraft on top.

Boeing aims to bring its space flight program back into orbit on Tuesday after the final test in 2019 fails, and will fly the Starliner capsule to the International Space Station (ISS) on an unmanned spacecraft.

The spacecraft will be launched by the United Launch Alliance-manufactured Atlas V rocket from Cape Canaveral Space Force Base in Florida at 1:20 pm Eastern Standard Time (1720 Greenwich Mean Time).

The mission’s live stream, Orbital Flight Test-2 (OFT-2), will be published on the NASA website.

Approximately 30 minutes after launch, the Starliner capsule launches a thruster into orbit and all day long. Space station, Docking is set at 1:37 pm on Wednesday.

The weather forecast currently predicts a 60% chance of launch, with clouds and lightning being the main hurdles.

NS Test flight It was supposed to take place on Friday, but had to be rescheduled as the Russian science module accidentally fired a thruster after docking with the ISS and removed the orbital outpost from its normal direction.

After ending the Space Shuttle program in 2011, NASA signed billions of dollars contracts with both Boeing and SpaceX to provide astronaut taxi services to space stations and reliance on Russian rockets in the United States. I’m done.

The SpaceX program has moved forward faster and is currently undertaking three crew missions.

The Boeing program is late.Testing the first unmanned spacecraft Flight In December 2019, Starliner Capsules experienced a software problem that prevented them from docking on the ISS and returned to Earth prematurely.

NASA later identified the 80 corrective actions that Boeing needed to take, and characterized the test as a “highly visible close call” in which the spacecraft could have been lost twice in the meantime.

Steve Stitch, the manager of NASA’s commercial crew program, told reporters last week that he was confident this time.

“We want it to work, we expect it to work, and we’ve made all the preparations we can,” he said. ..

“The Starliner is a great vehicle, but I know how difficult it is. It’s also a test flight and I’m completely hoping to learn something from this test flight.”

When the spacecraft lands in the western desert at the end of the mission, it will carry over 400 pounds (180 kilograms) of cargo and crew supplies to the ISS and return over 550 pounds of cargo, including air tanks.
