This Week in Space 103: Starship's Orbital Feat

1 hour 6 minutes

Last week's test flight of SpaceX's Starship--its third so far--was a mixed bag. The successful launch, ascent, staging, and testing of propellant transfer and the cargo bay door were all brilliant, yet both vehicles were destroyed before completing their planned trajectories, and the upper stage didn't make it into orbit (though it did reach "orbital velocity," according to Elon). So what's the real story on this test flight? When will the next one be? How close is SpaceX to routine launches of Starship, and when might it be ready to land NASA astronauts on the moon? And finally--an interstellar Starship, really Elon? Space.com ace reporter Mike Wall--that's Dr. Mike Wall to you--joins us with the details.
