SpaceX founder Elon Musk has been sharing a number of updates about his company’s progress on Starship this week. Along with footage of the assembly process of the current ‘SN1’ prototype of Starship, he explained on Twitter some of the other considerations and strategies the company is working with as it works on the new spacecraft and tries to fly it to space this year.

Musk said that SpaceX is iterating at a much faster pace with Starship than it has recently with Falcon, since Falcon’s design more or less stabilized once it started working consistently. He noted that the ability to progress with the design towards having a production vehicle is dependent on the number of interactions of the prototypes of the spacecraft, multiple by the progress achieved between each version.
