NASA and SpaceX conducted a formal verification of the company’s emergency escape, or egress, system at Kennedy Space Center’s Launch Complex 39A in Florida on Sept. 18, 2019. NASA astronauts Bob Behnken and Shannon Walker participated in the exercise to verify the crew can safely and swiftly evacuate from the launch pad in the unlikely event of an emergency before liftoff of SpaceX’s first crewed flight test, called Demo-2.

“This demonstration allowed all the various teams responsible for ground operations, system design, ground safety and emergency management to observe and verify the system is ready for operational use,” said Steve Payne, launch operations integrator for the agency’s Commercial Crew Program. “It’s a system we hope we never have to use, but we have to be prepared for every scenario.”

During the exercise, Behnken and Walker demonstrated two escape methods to show the crew could leave the 265-foot-level of the launch tower quickly. One method was an expedited non-emergency egress, where the crew started at the end of the crew access arm, called the white room, as if they just exited the capsule, and descended the crew access tower by taking the elevator to the base of the launch pad. Then, they were picked up by the pad team to be returned to crew quarters.

The other method involved an emergency egress, where the crew and pad team started at the crew access arm and escape to the ground using the slidewire baskets, with all alarms and fire suppression systems activated. From there, they boarded an armored vehicle that took them to safety.

“Safety of crew members is the top priority,” Walker said. “This was a great opportunity to test the emergency egress system and procedures on the pad.”

SpaceX provided a demonstration of activating alarms and beacons, putting on emergency breathing air bottles and activating the water deluge system on the crew access level, followed by egress from the white room. The astronauts also practiced loading into the baskets. The release mechanisms were also tested, and a weighted empty basket was sent down the length of the slidewire cable to the landing area.

The slidewire baskets have had a number of design improvements since they were used during the shuttle era. A new braking system was added that regulates the speed as astronauts descend the slidewire, which makes for a smoother ride for the crew.  Adjustments to the system have also made dismounting the slidewire baskets much easier than with the previous design.

Also, the platform used for emergency escape on the tower was relocated and reinstalled to the 265-foot-level, up 70 feet from its original shuttle-era location, in order to accommodate a taller launch vehicle.

“If the emergency egress system were ever to be needed to escape from a hazardous event, we want to have complete confidence that it will operate as designed and get our flight crew and pad personnel off the tower quickly and safely,” Payne said.

The verification team also included personnel from the Astronaut Office at NASA’s Johnson Space Center in Houston, NASA Flight Surgeons, SpaceX systems engineers, Kennedy Aero Medical, Commercial Crew Program Safety, and other observers.

“Each time today when we headed down the crew access arm, I couldn’t help but think about what it will be like to strap into Dragon on launch day,” Behnken said. “It’s exciting to have this verification test behind us on our way to the SpaceX Demo-2 mission.”

As commercial crew providers SpaceX and Boeing 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.

NASA, SpaceX Coordinate Crucial Astronaut Recovery Exercise

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.

NASA’s Commercial Crew Program Target Flight Dates

*NASA and Boeing provided updates on Oct. 11, 2019. For the details on Boeing flight tests and the schedule, visit https://go.nasa.gov/328xeSL.

The next generation of American spacecraft and rockets that will launch astronauts to the International Space Station are nearing the final stages of development and evaluation. NASA’s Commercial Crew Program will return human spaceflight launches to U.S. soil, providing reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements. To meet NASA’s requirements, the commercial providers must demonstrate that their systems are ready to begin regular flights to the space station. Two of those demonstrations are uncrewed flight tests, known as Orbital Flight Test for Boeing, and Demonstration Mission 1 for SpaceX. After the uncrewed flight tests, both companies will execute a flight test with crew prior to being certified by NASA for crew rotation mission. The following schedule reflects the most recent publicly-releasable dates for both providers.

Targeted Test Flight Dates:
Boeing Orbital Flight Test: June 2018
Boeing Crew Flight Test: August 2018
SpaceX Demonstration Mission 1: February 2018
SpaceX Demonstration Mission 2 (crewed): June 2018
