Today, May 21st, SpaceX’s Crew Dragon spacecraft atop Falcon 9 rocket was rolled out to Launch Pad 39A at the Kennedy Space Center (KSC) in Florida, and raised vertical for debut crewed flight, scheduled for May 27th at 4:32 p.m. Eastern Time. The crew that will be launched on a voyage to the International Space Station (ISS) next week are a pair of NASA Astronauts, veteran Space Shuttle pilots Robert Behnken and Douglas Hurley.

The mission, known as Demo-2, will mark the first crewed rocket flight launched from American soil in nearly a decade. Demo-2 is a test flight to certify the Crew Dragon spacecraft can safely and reliably transport humans to space. The brave astronauts Behnken and Hurley will pave the way towards launching crews more frequently from the United States.

 

 

Before Dragon was attached atop Falcon 9, its engines and thrusters were fueled with hypergolic hydrazine and nitrogen tetroxide propellants. Then crews attached Dragon atop Falcon 9, horizontally inside a hangar, and made sure all mechanisms work well. SpaceX crews transported it about four miles from the hangar to Launch Pad 39A at KSC, and used a crane to lift the gigantic 215-feet rocket vertically. “The rocket, topped by the Crew Dragon spacecraft, arrived at the launch pad Thursday morning,” NASA shared.

 

SpaceX will conduct a static-fire test soon. The special Falcon 9 will be fueled with rocket-grade kerosene and cryogenic liquid oxygen propellants. During the static-firing, the rocket’s nine Merlin 1D engines will be ignited for a few seconds while its grounded to the launch pad. The test is to assess the rocket has no issues before flight. It the brief firing goes smoothly, the rocket booster will launch Behnken and Hurley into orbit on Wednesday. The agency shared a series of photographs via Twitter of the rocket raised at the launch complex.

 

 

“Meanwhile, NASA and SpaceX managers are gathered at Kennedy, with some participating remotely to maintain physical distance, for the Demo-2 Flight Readiness Review (FRR). The review will focus on the readiness of SpaceX’s crew transportation system; the readiness of the station program and its international partners to support the flight; and the certification of flight readiness,” NASA wrote in a press release. As crews prepare the rocket at the launch pad, the Flight Readiness Review prepares mission-essential personnel ahead of the historic mission that will return human spaceflight capabilities to the United States of America.

Astronauts Behnken and Hurley have extensive experience as Space Shuttle and military pilots. During the Demo-2 mission, they will carry out a series of test objectives to ensure SpaceX’s Dragon spacecraft is safe to transport astronauts during operational missions. Behnken and Hurley have been training at SpaceX headquarters for years on Dragon mock-up simulators, to familiarize themselves with every software and hardware feature. “When we evaluated the touchscreen interface we really did focus on the task at hand and trying to get good performance for that specific task,” Behnken said earlier this month. Crew Dragon is capable of operating with full autonomy. However, during Demo-2, one of the test objectives is to switch to manual control to test the craft’s capabilities. Testing the manual feature ensures the system works in case future crews need to pilot craft due to a technology glitch or emergency, “The Dragon spacecraft does have a lot of capabilities for us to intervene manually.” Behnken added, “We do have a series of manual capabilities that allow us to really protect ourselves if the automation was to have some sort of a problem with it. [Hurley] …Should have the opportunity a couple of times during the [Demo-2] flight to manually fly the vehicle with those interfaces."

SpaceX released an interactive online simulator that is a replica of what Astronauts Behnken and Hurley used to train for the Demo-2 mission. The interactive simulator allows players to try to dock the Crew Dragon spacecraft to the International Space Station, using similar controls the astronauts will use during their voyage in space.

The astronauts arrived at the Kennedy Space Center yesterday, where they will review launch day preparedness and perform a dress rehearsal ahead of the debut flight. NASA will broadcast all events Live via NASA TV, video and schedule below.
