NASA’s SpaceX Demo-2 mission passed its final major review today at the agency’s Kennedy Space Center in Florida, and teams received the “go” to proceed toward launch. Liftoff of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft, carrying NASA astronauts Robert Behnken and Douglas Hurley, is scheduled for Wednesday, May 27, at 4:33 p.m. EDT from Kennedy’s Launch Complex 39A.

The mission will return human spaceflight to the International Space Station from U.S. soil on an American rocket and spacecraft as a part of NASA’s Commercial Crew Program. Demo-2 will be SpaceX’s final test flight to validate its crew transportation system, including the Crew Dragon, Falcon 9, launch pad and operations capabilities.

“We’re burning down the final paper. All the teams are a go, and we’re continuing to progress toward our mission,” said Kathy Lueders, manager, NASA Commercial Crew Program. “I’m very proud of the team. We are continuing to be vigilant and careful, and make sure we do this right.”

In this morning’s official forecast, the U.S. Air Force 45th Weather Squadron predicted a 60% chance of unfavorable weather conditions for the Demo-2 mission. The primary weather concerns that could prevent launch are flight through precipitation, thick and cumulus clouds.

However, 45th Weather Squadron Launch Weather Officer Mike McAleenan pointed out things are looking up.

“It certainly has been trending better over the last day or two for launch weather,” McAleenan said. “If I was to issue the forecast today, right now, we would probably be down to 40% chance of violation.”

Crew members Behnken and Hurley remain in quarantine, a routine part of prelaunch preparations for astronauts journeying into space. On Saturday, they took part in a full dress rehearsal of launch day, including suiting up and climbing aboard the Crew Dragon at Launch Complex 39A.

“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,” said Norm Knight, deputy director, Flight Operations, NASA Johnson Space Center. “We’re definitely ready to press forward.”

Upon arriving at the space station, Behnken and Hurley will join the Expedition 63 crew to conduct important research as well as support station operations and maintenance. While docked to the station, the crew will run tests to ensure the Crew Dragon spacecraft is capable on future missions of remaining connected to the station for up to 210 days.

“I think the on-orbit crew is definitely ready for some company, and very much looking forward to the launch this Wednesday,” said Kirk Shireman, manager, NASA International Space Station Program. “The ISS team is ready to support the docking of Crew Dragon.”

The specific duration for this mission will be determined after arrival based on the readiness of the next commercial crew launch. Finally, the mission will conclude with the Crew Dragon undocking from the station, deorbiting and returning Behnken and Hurley to Earth with a safe splashdown in the Atlantic Ocean.

Teams from NASA and SpaceX practiced removing astronauts from a Crew Dragon spacecraft on Tuesday, Aug. 13, at Port Canaveral in Florida, preparing for when humans return to Earth from a mission to the International Space Station as part of NASA’s Commercial Crew Program.

The joint simulation involved a mock-up of the spacecraft and Go Searcher, one of the SpaceX ships that will recover the spacecraft and astronauts after splashing down in the Atlantic Ocean. NASA astronauts Doug Hurley and Bob Behnken, who will fly to and from the space station aboard Crew Dragon for the SpaceX Demo-2 mission, participated in the exercise.

“Integrated tests like today’s are a crucial element in preparing for human spaceflight missions,” Hurley said. “This opportunity allowed us to work with the recovery team and ensure the plans are solid for the Demo-2 mission.”

The event marked the first time a fully integrated NASA and SpaceX team worked together on the ship to go through an end-to-end practice run of how the teams will recover and extract the astronauts when they return from the space station in Crew Dragon. Hurley and Behnken were taken out of the spacecraft, given a mock medical evaluation and then transported to the Cape Canaveral Air Force Station Skid Strip, or airport.

“We’re making sure that the team integrates together — that’s a key to any successful mission,” said Ted Mosteller, the NASA recovery director in charge of the agency’s team for the Commercial Crew Program. “We worked on successfully doing what we need to do to take care of the crew once they return to Earth.”

The purpose of the exercise, Mosteller pointed out, was to ensure participants knew their roles and responsibilities — and where they were supposed to be staged on the 150-foot vessel. He was extremely pleased with the results.

“It feels really good; it has been a lot of hard work to get us to this point,” Mosteller said. “There was a lot of collaboration, and it was a very positive experience for the integrated team.”

For Hurley and Behnken, it’s another milestone on the path to their historic flight.

“We are both looking forward to the Demo-2 flight and having the opportunity to return to the International Space Station,” Behnken said. “Each of these exercises puts us one step closer to fulfilling NASA’s mission of returning astronauts to the International Space Station from U.S. soil.”

As commercial crew providers Boeing and SpaceX begin to make regular flights to the space station, NASA will continue to advance its mission to go beyond low-Earth orbit and establish a human presence on the Moon with the ultimate goal of sending astronauts to Mars.

The activity is part of a series of integrated simulations bringing together NASA and SpaceX flight control teams to complete multiple practice runs for each dynamic phase of a mission from launch to splashdown. These simulations provide the teams plenty of practice to ensure they safely and successfully perform the planned operations of the actual spaceflight, with opportunities to fine-tune their procedures and gain experience on how to solve problems should they arise.

Astronauts Bob Behnken and Doug Hurley are assigned to take the first flight on SpaceX’s Demo-2 mission, and the two have been working closely with SpaceX throughout the design and construction of the spacecraft, offering up the experience they gained on previous spaceflights. Joint simulations bring them together with the teams that will support them from the ground to practice for the mission — including handling any challenges that might arise during flight.

The Demo-2 flight test will be the Crew Dragon’s chance to demonstrate a complete mission with astronauts, from launch to landing, and will put SpaceX on its way to earning certification from NASA’s Commercial Crew Program. Once the spacecraft is certified, SpaceX can begin regular flights to the space station with long-duration crews aboard.

In March, SpaceX’s Demo-1 mission proved the Crew Dragon and its Falcon 9 rocket worked as designed. The mission tested a new launch configuration, checked maneuverability demonstrations in free flight and ensured the crew’s ability to transfer power and data between the spacecraft and the space station. With those boxes all successfully checked, the Crew Dragon became the first commercial spacecraft built to carry humans to dock with the space station. Its subsequent safe reentry and splashdown in the Atlantic Ocean was an important step toward proving the spacecraft is ready to carry humans onboard.
