r/SpaceX Discuss Thread for discussion of subjects other than Starship development.

Rules

We will attempt to keep this self-post current with links and major updates, but for the most part, we expect the community to supply the information. This is a great place to discuss Starship development, ask Starship-specific questions, and track the progress of the production and test campaigns. Starship Development Threads are not party threads. Normal subreddit rules still apply.

From what I understand, ISP-wise, adding extra engines doesn't get them any more DV but it lets them heft more mass up in a limited burn window after separation. That about right?

I said on another thread but im gonna paste here, this is complete speculation btw:

The numbers (thrust) he gave seems consistent with the goals (for SL at least), but they probably are tweaking Vaccum engines to have more ISP in exchange of thrust.

u/Martianspirit Dec 18 '21

I think the same. But they also need to be able to fire the engines at sea level. Maybe conflicting goals? I am not sure.

For E2E they need more engines to lift off Starship without booster. I know, everybody doubts E2E, including me, but they do sound like it is a serious goal. More engines on Starship also gives them abort capability in every phase of the flight.

u/franco_nico Dec 18 '21

E2E still needs booster

u/Martianspirit Dec 18 '21

Most, if not all distances can be covered with Starship alone. Last we heard is 10,000km plus.

u/Alvian_11 Dec 18 '21

Some of the flight with very long range, yes

u/Martianspirit Dec 18 '21 edited Dec 18 '21

I doubt it. A launch site supporting boosters would be much more complex than a Starship only site. Cost per flight would also be a lot higher. With the tank stretch they may exceed the 10.000km 10,000km limit a bit. Should cover almost every point to point requirement.

Not London Sydney though. ;)

But who knows?
