After months of anticipation, SpaceX’s new crew-worthy spacecraft,Crew Dragon, reached its last major milestone in a years-long testing program.
The success paves the way for astronauts to begin using the spacecraft for rides to the International Space Station this year.
The capsule was launched — without people on board — atop a SpaceX Falcon 9 rocket from Kennedy Space Center in Florida at 10:30 am ET on Sunday. About 84 seconds after liftoff, Crew Dragon intentionally ejected itself from the rocket to simulate how it would carry passengers to safety if something goes awry during launch.
Sunday’s launch came after bad weather on Saturday forced a 24-hour delay.
SpaceX CEO and chief engineer Elon Musk on Twitter called the in-flight abort test a “risky mission” that’s “pushing the envelope in so many ways.”

SpaceX’s Falcon 9 rockets are designed to be reusable, and the one used Sunday already made three trips to space. But for the purposes of the test, the rocket was intentionally destroyed after Crew Dragon executed its emergency abort, erupting into a ball of fire mid-air. Crews will work to recover as much of the debris from the vehicle as possible.
A successful emergency abort test will mark a significant win for SpaceX. There is still some testing left to do, such as additional checks on the vehicle’s parachute design, Kathy Lueders, NASA’s Commercial Crew Program manager, said during a press briefing Friday. But officials can now work to finish the long-awaited verification process that will deem Crew Dragon ready for its first mission with astronauts on board.
The next step will be for SpaceX and NASA to closely review the data collected by the in-flight abort test, including information collected by two sensor-clad test dummies that rode aboard Crew Dragon Sunday. They’ll help determine what type of G-forces astronauts would experience during such a launch abort
NASA asked the private sector to develop crew-worthy spacecraft to replace the Space Shuttle program after it was retired in 2011. SpaceX was allotted $2.6 billion and Boeing was awarded $4.2 billion in 2014, and the space agency initially predicted their vehicles would be ready to fly astronauts by 2017. But development of both spacecrafts took years longer than expected. Meanwhile, NASA haspaidRussia billions of dollars for American astronauts to ride aboard Russia’s Soyuz capsules.
