You might want to dial back your expectations for the first high-altitude SpaceX Starship flight. Elon Musk now says the flight with the SN8 prototype will top out at 15km, or close to 50,000ft, instead of the 18km and 60,000ft he’d mentioned earlier. It’s not clear what prompted the lowered expectations, but Musk added that the rocket would get its nosecone and front flaps “next week.”

He also showed current progress on the prototype, noting that the rear body flaps were already in place. An SN9 prototype is due in October.
