It’s not certain just when SN8 will make its first flight. That could take a while depending on the success of ground tests. SpaceX first asked for permission to conduct a high-altitude flight in early February.
Whenever the flight happens, it will represent an important milestone for SpaceX. Starship is the key to the company’s future now that Crew Dragon appears to be a success. While 60,000ft is far from space (that starts at roughly 62 miles), reaching such altitude would show that Starship is viable for more than brief jumps. It would also represent one of the last major steps before Starship reaches orbit and, eventually, fulfils SpaceX’s dreams of space tourism and interplanetary journeys.
SN8 Starship with flaps & nosecone should be done in about a week. Then static fire, checkouts, static fire, fly to 60,000 ft & back.
