NASA and SpaceX begin final pre-flight checks on Falcon 9 rocket ahead of Wednesday mission

The weather may still threaten the historical NASA and SpaceX launch, but the team is still moving ahead with their plans.  

Falcon 9, topped with the Crew Dragon capsule, is standing upright on the pad and the access arm is swung open for astronauts Bob Behnken and Doug Hurley to walk across Wednesday.

This will be the first time in nine years NASA has launched American astronauts to the International Space Station from US soil. 

Weather for the launch is currently 60 percent favorable as NASA and SpaceX begin the final pre-flight checks before the craft takes off Wednesday at 4:33 pm ET.  

The mission, dubbed ‘Launch America,’ passed its final major review Monday and the teams involved received the ‘go’ for tomorrow’s launch. 

 

NASA and SpaceX are gearing up to send two American astronauts to the ISS aboard an American rocket. The access arm has been swung open, which  Bob Behnken and Doug Hurley will walk across to board the Crew Dragon capsule atop the Falcon 9 craft

Kathy Lueders, manager, NASA Commercial Crew Program, said: ‘We’re burning down the final paper. All the teams are a go, and we’re continuing to progress toward our mission.’

‘I’m very proud of the team. We are continuing to be vigilant and careful, and make sure we do this right.’

A thick cloud is hovering over Cape Canaveral Tuesday morning, but that is not stopping NASA and SpaceX from setting up for the launch.

The two astronauts remain in quarantine, a routine part of prelaunch preparations for astronauts journeying into space.

Norm Knight, deputy director, Flight Operations, NASA Johnson Space Center, said: ‘It was a really good review today, and from a crew perspective, we were very happy with the discussions that took place — the thoroughness of the review.’

‘We’re definitely ready to press forward.’

News outlets have also began claiming their spots around the launch pad and are setting up their gear to cover the event.

However, the unfavorable weather is causing issues for some crews – a CBS News reflector toppled over from the strong winds Tuesday morning.

Prior to tomorrow’s launch, NASA will lower Falcon 9 into a horizontal position to complete the final pre-flight checks. 

Mike McAleenan, launch weather officer with the 45th Weather Squadron, said in a briefing on Monday that the weather is expected to improve from a 40 percent to 60 percent by launch day.

‘It’s really a dynamic situation that’s developing across Florida,’ said McAleenan.

‘We have some hope for launch day.’ 

If the highly anticipated manned launch is delayed, NASA said it will make another attempt to fly the Crew Dragon capsule to the ISS on Saturday.

The craft will lift off from Launch Pad 39A and Crew Dragon will hit speeds of 17,000 miles per hour as it travels into Earth’s orbit towards the ISS.

Once in orbit, the crew and SpaceX mission control will validate the performance of the craft by testing the environmental control system, displays, maneuvering thrusters and other technologies.

About 24 hours after takeoff, Crew Dragon should be in position to dock with the ISS and will do so autonomously.

After successfully docking Behnken and Hurley will be joined with the other members on the space station and become part of the Expedition 63 crew.

Kirk Shireman, manager, NASA International Space Station Program, said: ‘I think the on-orbit crew is definitely ready for some company, and very much looking forward to the launch this Wednesday.’

‘The ISS team is ready to support the docking of Crew Dragon.’ 

The two astronauts performed their ‘dress rehearsal’ Saturday, Hurley said. They arrived at the launch pad at Kennedy Space Center in Florida wearing their SpaceX-designed spacesuits and in a Tesla with the license plate ISSBND, ISS Bound.

They then climbed into their Crew Dragon spacecraft at Launch Complex 39A. SpaceX also successfully tested their Falcon 9 rocket Friday.

Their instructions are to perform tests on the capsule, along with conducting research and other tasks with the ISS astronauts.

Once the mission is completed, Crew Dragon will autonomously undock with Behnken and Hurley inside and return to Earth.
