  • Saying a suborbital flight is a partial orbit is like saying a cessna can partially achieve hypersonic velocities

    Starship reached over 26000km/h, it had enough energy to be in orbit if it was in a circular orbit. The orbit was intentionally left eccentric enough that the perigee was within the atmosphere, so that a deorbit burn was not required.

    This is a cessna going mach 4.99 and you’re being pedantic enough to say it was not hypersonic.

    I agree with the rest of what you say though. As fun as it is to watch, Starship is over budget and behind schedule. Elon has over promised (pronounced “lied to get government subsidies”) on timelines and capabilities so much that it may jeopardize the Artemis program. Which makes me mad.

    That’s what I mean by status quo bias. Just because there are roads now doesn’t mean that those are the only option. We have spent a fuckton of money and a fuckton of effort over the last century building these roads. But the problem is that cars don’t scale. Self driving or not. So as we continue to spend fucktons of money and effort on transportation, we should allow ourselves to consider all options. Rebuilding all roads to accommodate self driving cars (as the original tweet implies) is probably the worst option. There are options that are better for the economy, better for the environment, and better for people.

    Also, I don’t think any serious person is suggesting replacing ALL roads with rail. Obviously, roads are an important part of any transit network. It’s just that we should not ONLY build roads, and not build ALL roads ONLY for cars.

    Building roadways to achieve the current coverage for the entire US was a massive undertaking that required a huge effort over multiple decades. Compared to that, building railways is downright trivial. Let’s not forget that self driving trains already exist, but self driving cars don’t. People should not let their status quo bias blind them to reality.
