  Sorry, there are so many Musk stans that would say that exact thing, I 100% missed the joke

  Mmm I’d take Common Sense Skeptic’s spaceX videos with about a ton of salt. They’ve got a real big bug up their ass about spaceX for some reason.

    Which part of the video is wrong? The fact is that it failed to reach planned velocity. This is public record. If it did not reach planned velocity then it did not reach the non-circualized suborbit that they intended. They were not “just a circulization away from orbit.”

    The CSS channel was created when Musk and Shotwell were making bonkers claims about their Mars plans, as well as other crazy bullshit like the suborbital rocket airline stuff. The point of CSS is that none of their claims pencil out if you do even basic math, and they proved that by doing the math. They’ve also gone after other space grifters like orbital assembly.

      Haven’t watched the video, but what do you think circularization is? If you’re “just a circulization away from orbit”, you are indeed going a bit slower than orbital velocity. There’s no point to going orbital velocity if your trajectory still brings you back inside the atmosphere. To get to orbit you want to raise your periapsis outside the atmosphere, and you do that by doing a burn at the apoapsis, which is what we commonly call “circularization”.

        The planned goal of the mission was to achieve orbital velocity but not orbital trajectory. This was because they had not yet demonstrated the ability of their vac engines to relight in space. If they go into a stable orbit but can’t relight they can not deorbit and they become space junk.

        They initially claimed that this was a success (they achieved target velocity) but subsequent analysis was they were quite a bit off. Also because their engine relight test was failed/cancelled they will also not be allowed to attempt a stable orbit in IFT4. They have to demonstrate relight/deorbit capability before they will be allowed to attempt stable orbit.
