explosion of the Crew Dragon capsule during an April engine test pushed back the company's plans for its first crewed mission. But SpaceX appears to be making progress with a new round of testing. SpaceX tweeted a video on Thursday that shows a brief but fiery test of Crew Dragon's new and improved launch escape system. We see one set of the capsule's thrusters kick in for a few seconds before the video fades to black.
