Behnken and Hurley are more than crewmates: they are also good friends. They entered the astronaut corps at the same time – the class of 2000; they both married astronauts; they were even in each other’s weddings.
Both flew twice to the International Space Station on separate space shuttle missions. Now they’re preparing to fly together – an experience that’s not just enjoyable, but helpful as well.
“We can think ahead in terms of what the other person is going to need, or what the other person is going to want, anticipate the next input, all those sorts of things, which really, in a test flight like this, goes a long way,” Behnken said. “You can really anticipate the other person’s reactions versus to have a, ‘Well, I don’t know, Doug. How do you feel about the next series of events?’ I already know the answers to those questions, and it makes a big difference when you’re doing something as critical as spaceflight.”

The room is part of the Astronaut Crew Quarters, which occupies about 26,000 square feet of Kennedy’s Neil Armstrong Operations and Checkout Building. The crew quarters features 23 bedrooms — each with a bathroom — and the suit room, where Apollo and shuttle crews suited up for flight.
Before today, the last crew to suit up in this room was the STS-135 crew, which included Hurley, the mission’s pilot, in July 2011.
On Monday, March 30, 2020 at a SpaceX processing facility on Cape Canaveral Air Force Station in Florida, SpaceX successfully completed a fully integrated test of critical crew flight hardware ahead of Crew Dragon’s second demonstration mission to the International Space Station for NASA’s Commercial Crew Program; the first flight test with astronauts onboard the spacecraft. NASA astronauts Robert Behnken and Douglas Hurley participated in the test, which included flight suit leak checks, spacecraft sound verification, display panel and cargo bin inspections, seat hardware rotations, and more.

SpaceX Demo-2 astronauts Robert Behnken and Douglas Hurley will suit up inside the suit room in the Astronaut Crew Quarters inside Kennedy’s Neil Armstrong Operations and Checkout Building. A team of SpaceX suit technicians will help them as they put on their custom-fitted spacesuits and check the suits for leaks.
SpaceX spacesuits are designed for safety and functionality – but with a nod to comfort and style. The primary purpose of the spacesuit is to provide a cocoon of pressurization, protecting from potential depressurization. A port on the suit’s thigh connects to life support systems, including air and power. The suits also include touchscreen-compatible gloves and a flame-resistant outer layer.
The helmet is custom manufactured using 3D printing technology and includes integrated valves, mechanisms for visor retraction and locking, and microphones.

The SpaceX Demo-1 mission in March 2019 was the spacecraft’s first flight test. During that uncrewed mission, the fully autonomous Crew Dragon launched aboard a Falcon 9 rocket, rendezvoused and docked with the orbiting laboratory, undocked several days later and returned to Earth with a splashdown in the Atlantic Ocean off the Florida coast.
Throughout the flight, the spacecraft’s performance and capabilities were monitored from the ground, while an anthropomorphic test device nicknamed “Ripley” rode inside the Crew Dragon as a “passenger.” Ripley was fitted with sensors around the head, neck and spine to record everything an astronaut would experience throughout the mission, such as the forces, acceleration, protection offered by Crew Dragon’s seats, and overall environment.

Demo-2 raises the stakes, taking Demo-1 a critical step further with the addition of a crew: veteran astronauts Robert Behnken and Douglas Hurley.
This mission will serve as an end-to-end flight test to validate the SpaceX crew transportation system, from launch to docking to splashdown. It is the final flight test for the system to be certified for regular, crew flights to the station as part of NASA’s Commercial Crew Program.

Anticipation continues to build at NASA’s Kennedy Space Center in Florida just one day before the scheduled launch of the agency’s SpaceX Demo-2 mission. A SpaceX Falcon 9 rocket and Crew Dragon spacecraft will carry two American NASA astronauts, Robert Behnken and Douglas Hurley, to the International Space Station for the agency’s Commercial Crew Program. Liftoff from Kennedy’s historic Launch Complex 39A is targeted for Wednesday, May 27, at 4:33 p.m. EDT — an instantaneous launch window.

“I don’t have to tell you all how exciting it is to have the first flight of humans to space from the Kennedy Space Center in nine years,” Kennedy Space Center Director Bob Cabana said during a briefing Tuesday, adding that the launch pad’s history only adds to the significance of NASA’s SpaceX Demo-2 launch. “Now, rather than rusting away in the salt air, through our partnership with SpaceX, that pad is being used once again, and it’s now for our Commercial Crew Program as well as other missions for SpaceX, and I think that’s absolutely outstanding.”
NASA Administrator Jim Bridenstine recognized the years of hard work required to prepare for this mission, including at the Florida spaceport.
“It’s been nine years since we’ve had this opportunity,” Bridenstine said. “And Bob Cabana, we want to thank you for all the great work you’ve done getting us up to this point, getting the Kennedy Space Center ready. Everything is looking good. As of right now, we are ‘go’ for launch.”
At the launch complex, SpaceX teams continue to prepare for liftoff. Prior to tomorrow’s targeted launch, SpaceX is bringing the rocket horizontal to perform additional preflight checkouts of Falcon 9, Crew Dragon, and the ground support system, including an inspection of the ground-side chilled water radiator feed that keeps Crew Dragon cool before launch. These checkouts do not impact the flight system or targeted launch date, and the vehicle is scheduled to return to vertical later tonight.
The U.S. Air Force 45th Weather Squadron now predicts a 60% chance of favorable weather conditions for NASA’s SpaceX Demo-2 launch — a change from the previous days’ projections, which called for a 40% chance of “go” conditions. The primary weather concerns for launch are flight through precipitation, anvil and cumulus clouds.
“We are so proud and happy for Doug and Bob. It feels kind of like one of your close family members having a great lifetime achievement — and really, that’s what it is,” said astronaut Nicole Mann, herself a member of the NASA astronaut team slated to fly on a future Commercial Crew Program launch on Boeing’s Starliner spacecraft. “I can speak for the astronaut office — that’s how we all feel, so proud for everything that they’ve accomplished with the NASA and SpaceX team to get ready for this launch.”
This will be SpaceX’s final test flight for NASA’s Commercial Crew Program and will provide critical data on the performance of the Falcon 9 rocket, Crew Dragon spacecraft, and ground systems, as well as in-orbit, docking, and landing operations.
While docked to the space station, Behnken and Hurley will join the Expedition 63 crew already on board the orbiting laboratory: astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner.
“That’s at the core of what we’re doing here today, to continue the incredible legacy of work that we’ve done on the International Space Station,” said NASA astronaut Kjell Lindgren, who flew to the station in 2015 aboard a Roscosmos Soyuz spacecraft as part of the Expedition 44/45 crew. “We’ve had humans living and working on that orbital outpost for almost 20 years, conducting science and research to extend our presence in the solar system and to improve life back here on Earth. This launch represents an extension of that capability.”
Bridenstine acknowledged the impact of the coronavirus pandemic on the nation, even its influence on the briefing itself, as he and other briefers sat several feet apart, speaking to cameras in an auditorium empty of press.
“We would love to have this room full. We would love to have reporters; we’d love to have it filled with space enthusiasts,” he said. “Our country has been through a lot. But this is a unique moment when all of America can take a moment and look at our country do something stunning again, and that is to launch American astronauts on an American rocket from American soil to the space station.”
NASA and SpaceX will provide live coverage of the launch activities beginning Wednesday, May 27, at 12:15 p.m., leading up to liftoff and through arrival at the space station at 11:39 a.m. on Thursday, May 28.

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.
